Exam A

QUESTION 1Identify the two security features incorporated in the Oracle Solaris 11 Cryptographic Framework.

A. Layer 5 IP address encryptionsB. Internet protocol securityC. Diffie-Kerberos coaxial key encryptionD. Signed cryptographic plugins (providers)E. Kernel support for signed antivirus plugins

Correct Answer: DESection: (none)Explanation

Explanation/Reference:Explanation:The framework enables providers of cryptographic services to have their services used by many consumers in the Oracle Solaris operating system. Another namefor providers is plugins. The framework allows three types of plugins:

* User-level plugins-Shared objects that provide services by using PKCS #11 libraries, such as pkcs11_softtoken.so.1.

* Kernel-level plugins-Kernel modules that provide implementations of cryptographic algorithms in software, such as AES.

Many of the algorithms in the framework are optimized for x86 with the SSE2 instruction set and for SPARC hardware.

* Hardware plugins-Device drivers and their associated hardware accelerators. The Niagara chips, the ncp and n2cp device drivers, are one example. A hardwareaccelerator offloads expensive cryptographic functions from the operating system. The Sun Crypto Accelerator 6000 board is one example.

* File or directory is present in the older snapshot but not in the newer snapshot --* File or directory is present in the newer snapshot but not in the older snapshot +* File or directory is renamedR

QUESTION 3Which five statements describe options available for installing the Oracle Solaris 11operating system using the installation media?

A. You can perform a text or LiveCD installation locally or over the network.B. The text Installer does not install the GNOME desktop. The GNOME desktop package must he added after you have installed the operating system.


C. The LiveCD Installation cannot be used to install multiple instances of Oracle Solaris.D. The LiveCD installer cannot be used if you need to preserve a specific Solaris Volume Table of Contents (VTOC) slice in your current operating system.E. The LiveCD Installer is for x86 platforms only.F. The GUI installer cannot be used to upgrade your operating system from Solaris 10.G. If you are installing Oracle Solaris 11 on an x86-based system that will have more than one operating system installed in it, you cannot partition your disk during

the installation process.H. The LiveCD installer can be used for SPARC or x86 platforms.

Correct Answer: ABDFSection: (none)Explanation

Explanation/Reference:Explanation:A: If the network is setup to perform automated installations, you can perform a text installation over the network by setting up an install service on the network andselecting a text installation when the client system boots.B: After a fresh install of Solaris 11 express, only the console mode is activated.To add Gnome, simply do :

$ sudo pkg install slim_install

This will install additional packages that are not installed by default.

D:The text installer advantages over the GUI installer include:*In addition to modifying partitions, the text installer enables you to create and modify VTOC slices within the Solaris partition.F: How do I upgrade my Solaris 10 or lower systems to Solaris 11? Unfortunately, you CAN'T. There is no direct upgrade installer or other tool that will allow you toupgrade from earlier releases of Solaris to Solaris 11. This is primarily due to the vast changes in the packaging mechanism in Solaris 10.

over a 24-hour period and peak utilization id displayed each hour.C. It is a sample of dbzone's CPU, virtual memory, and networking utilization.Physical memory is executed from the report.The sampling is taken every 10 minutes

over a 24-hour period and displayed each hour.D. It is a sample of dbzone's physical memory usage taken every 10 seconds and 24-hour period.Only peak virtual memory usage and CPU utilization are

displayed each hour.All other Utilization data is eliminated.E. It is a sample of dbzone's physical memory usage taken every 10 seconds and 24-hour period.Only peak memory usage is displayed each hour.All other

utilization data is eliminated.

Correct Answer: DSection: (none)Explanation

Explanation/Reference:Explanation:* (Not A, B, C): interval (here 10 seconds): Specifies the length in seconds to pause between each interval report.* duration (here 24 h)

* -R report[,report] (here high)Print a summary report.highPrint a summary report detailing the highest usage of each resource and zone during any interval of the zonestat utility invocation.

Note: The zonestat utility reports on the cpu, memory, and resource control utilization of the currently running zones. Each zone's utilization is reported both as apercentage of system resources and the zone's configured limits.

The zonestat utility prints a series of interval reports at the specified interval. It optionally also prints one or more summary reports at a specified interval.

The default output is a summary of cpu, physical, and virtual memory utilization. The -r option can be used to choose detailed output for specific resources.

QUESTION 5You are configuring NFS on a server. Select the two statements that are true.

A. Resources listed in /etc/dfs/dfstab are automatically shared on boot up.B. A directory cannot be shared if a subdirectory below it is already shared.C. Renaming a share created with the zfs set share command is not supported.D. NFS and SMB protocols cannot be used simultaneously to share the same directory.

Correct Answer: ACSection: (none)Explanation


Explanation/Reference:Explanation:A: ZFS can automatically share file systems by setting the sharenfs property. Using this property, you do not have to modify the /etc/dfs/dfstab file when a new filesystem is shared. The sharenfs property is a comma-separated list of options to pass to the share command. The value on is an alias for the default share options,which provides read/write permissions to anyone. The value off indicates that the file system is not managed by ZFS and can be shared through traditional means,such as the /etc/dfs/dfstab file. All file systems whose sharenfs property is not off are shared during boot.

QUESTION 6You have already generated a 256-bit AES raw key and named the keystore file /mykey. You need to use the key to create an encrypted file system.


Which command should you use to create a ZFS encrypted file system named pool1/encrypt using the /mykey keystore?

A. zfs create-oencryption = /mykey pool1/encryptB. zfs create-oencryption = 256-ccm-okeysource = raw, file : ///my key pool1/encryptC. zfs create-oencryption = AES keysource = /mykey pool1/encryptD. zfs create-oencryption = on keystore = /mykey pool1/encrypt

Correct Answer: BSection: (none)Explanation

Explanation/Reference:Explanation:Example: Encrypting a ZFS File System by Using a Raw Key

In the following example, an aes-256-ccm encryption key is generated by using the pktool command and is written to a file, /cindykey.file.

# pktool genkey keystore=file outkey=/cindykey.file keytype=aes keylen=256 Then, the /cindykey.file is specified when the tank/home/cindy file system is created.

# zfs create -o encryption=aes-256-ccm -o keysource=raw,file:///cindykey.file tank/home/cindys References:

of http://pkg.oracle.com/solaris/releaseIssue the pkg publisher command to view the publishers.Set the new publisher to sticky.Issue the pkg update commandto update the OS image.

Correct Answer: CSection: (none)Explanation

Explanation/Reference:Explanation:You can use the pkg set-publisher command to change a publisher URI.

Changing a Publisher Origin URI

To change the origin URI for a publisher, add the new URI and remove the old URI. Use the -g option to add a new origin URI. Use the -G option to remove the oldorigin URI.

# pkg set-publisher -g http://pkg.example.com/support \ -Ghttp://pkg.example.com/release example.com

Note: You can use either the install or update subcommand to update a package. The install subcommand installs the package if the package is not alreadyinstalled in the image. If you want to be sure to update only packages that are already installed, and not install any new packages, then use the updatesubcommand.References:

QUESTION 14Which three options describe the purpose of the zonep2vchk command?

A. Used on a Solaris 10 global zone to access the system for problems before migrating that system to a Solaris 10 branded zone.B. Used to access a Solaris 10 global zone for problems before migrating that zone to a Solaris 11 global zoneC. Used to create zonecfg template for a Solaris 10 global zone that that will be migrated to a solaris10 branded zone.D. Used to migrate an Oracle Solaris 11 global zone to a non-global zone.E. Used to migrate a Solaris 10 global zone to a non-global zone on the same server; the non- global zone can then be migrated to a Solaris 11 server as a

Solaris10 branded zone.

Correct Answer: CDESection: (none)Explanation

Explanation/Reference:Explanation:zonep2vchk- check a global zone's configuration for physical to virtual migration into non-global zone

The zonep2vchk utility is used to evaluate a global zone's configuration before the process of physical-to-virtual (p2v) migration into a non-global zone. The p2vprocess involves archiving a global zone (source), and then installing a non-global zone (target) using that archive

zonep2vchk serves two functions. First, it can be used to report issues on the source which might prevent a successful p2v migration. Second, it can output atemplate zonecfg, which can be used to assist in configuring the non-global zone target. zonep2vchk can be executed on a Solaris 10 or later global zone. Toexecute on Solaris 10, copy the zonep2vchkutility to the Solaris 10 source global zone.

When run on Solaris 10, a target release of S11 can be specified, which will check for p2v into a Solaris 10 Branded zone.

QUESTION 17You are troubleshooting the failure of a computer to mount an NFS file system hosted by a server (hostname mars) in the local area network.

Select the three commands that will enable you to identify the problem.

A. ping-s marsB. cat /etc/vfstabC. cat /etc/dfs/dfstabD. sharemgr show -vE. showmount -e marsF. rpcinfo-s mars | egrep `nfs|mountd'

Correct Answer: BEFSection: (none)Explanation

Explanation/Reference:Explanation:B:The mount point Error. The following message appears during the boot process or in response toan explicit mount request and indicates a non-existent mountpoint.mount: mount-point /DS9 does not exist.To solve the mount point error condition, check that the mount point exists on the client. Check the spelling of the mount point on the command line or in the /etc/vfstab file (B) on the client, or comment outthe entry and reboot the system.

Note: The /etc/vfstab file lists all the file systems to be automatically mounted at system boot time, with the exception of the /etc/mnttab and /var/run file systems.

E: showmountThis command displays all clients that have remotely mounted file systems that are shared from an NFS server, or only the file systems that are mounted by clients,or the shared file systems with the client access information. The command syntax is:

showmount [ -ade ] [ hostname ]

where -a prints a list of all the remote mounts (each entry includes the client name and the directory), -d prints a list of the directories that are remotely mounted byclients, -e prints a list of the files shared (or exported), and hostname selects the NFS server to gather the information from. If hostname is not specified the localhost is queried.

F: * mountd DaemonThis daemon handles file-system mount requests from remote systems and provides access control. The mountd daemon checks /etc/dfs/sharetab to determinewhich file systems are available for remote mounting and which systems are allowed to do the remote mounting.


* Commands for Troubleshooting NFS ProblemsThese commands can be useful when troubleshooting NFS problems.rpcinfo CommandThis command generates information about the RPC service that is running on a system.

QUESTION 18You want to deploy oracle Solaris 11 with the automated installer (AI). You need to make sure that your server and network meet the requirements for using AI.

Choose the three options that describe; the requirements for using AI.

A. You can create only one manifest per install service. If you need more than one manifest, create multiple install services.B. If two client machines have different architectures and need to be installed with the same version of the Oracle Solaris 11 OS, then create two AI manifests and

a single Install service.C. You need a separate install service for each different client architecture that you plan to install, and for each different version of the Oracle Solaris 11 OS that

you plan to install on client systems.D. If two client machines have different architectures and need to be installed with different versions of the Oracle Solaris 11 OS, then create two AI manifests and

two install services.E. The install server needs to be able to access an Oracle Solaris Image Packaging System (IPS) software package repository; the clients do not.F. The install server can be either an x86 machine or a SPARC machine.

Correct Answer: BEFSection: (none)Explanation

Explanation/Reference:Explanation:B:

Note: You can create custom AI manifests for particular clients. Create a custom XML AI manifest file. This method is best suited to an environment where fewsystems require custom provisioning. Most systems to be installed have identical or similar hardware and will be provisioned identically.

Write a script that dynamically creates an AI manifest for each client at installation time. Use this method to create a custom installation for each client, based onclient characteristics discovered at installation time.

E: AI Server Software Requirements includeSoftware package repositoryEnsure that the install server can access an IPS software package repository. AI requires the install/installadm package.

F: Install Server Requirements


Any system that meets these requirements can be used as an AI install server, including laptops, desktops, virtual machines, and enterprise servers. The installserver can be either an x86 machine or a SPARC machine. An x86 install server can install both SPARC and x86 clients, and a SPARC install server can installboth SPARC and x86 clients.

Note: To install clients over the network, AI requires a separate system to be an install server. On the install server, create an AI install service to provide a netimage and instructions for installing the Oracle Solaris 11 OS on different clients.

Serving a Local Repository Using SMF4. (A) Copy the repository files to the ZFS file system you created. This will increase the performance of repository accesses and avoid the need to remount the .isoimage each time the system restarts. (Be sure to use /mnt/repo, not /mnt/repo/, so that you copy the repo directory and not just the files and subdirectories in therepo directory.)

# rsync -aP /mnt/repo /export/repo2010_11You can use the df command to confirm the copy:

5.Once the files are copied, unmount the image and deallocate the block device.

6. Now that your local copy is ready, use the svccfg command to configure the repository server service, specifying the location of your local repository and settingreadonly to true:(D)#svccfg -s application/pkg/server setprop pkg/inst_root=/export/repo2010_11/repo (E)#svccfg -s application/pkg/server setprop pkg/readonly=true

7. Start the pkg.depotd repository service:(G) #svcadm refresh application/pkg/server(I)#svcadm enable application/pkg/serverReferences:

QUESTION 26The crash dump notification on your server is:

Documentation states that there should be two core files for each crash dump in the /var/crash directory named vmdump.0

Which command should you choose to display theses two files?

A. savecore-f vmdump.0B. dumpadm uncompressedC. gunzip vmdump.0


D. dumpadm-z off


Explanation/Reference:Explanation:Decompress using savecore -f vmdump.0

savecore - save a crash dump of the operating system

-fdumpfileAttempt to save a crash dump from the specified file instead of from the system'scurrent dump device. This option may be use-ful if the information stored on the dumpdevice has been copied to an on-disk file bymeans of thedd(1M)command.

QUESTION 28You need to migrate a UFS file system named /production_ufs to a ZFS file system named /production_ufs. The /production_ufs file system cannot be taken downor be out of production during the migration, and the current /production_ufs file system must remain active until the /ptoduction_zfs file system is copied and ready.

Which method allows you to meet both requirements?

1. Copy live data from /production_ufs to /production_zfs while /production_ufs is in use.2. When the copy is complete, /production_zfs will contain an up-to date copy of /production_ufs

A. Create a snapshot of the UFS file system.Create the new ZFS file system.Use cpio to copy data from the snapshot to the new ZFS file system.B. Create a new Boot Environment.Create the ZFS file system.Use lucreate -m to copy data from the Current UFS file system to the new ZFS file system.C. Mirror the existing UFS file system by using SVM.After both submissions are in sync, migrate one of the submissions to a ZFS file System by using Live

Upgrade.D. Create the new ZFS file system by using zfs create import to import data from the existing UFS file system into the new ZFS file systemE. Create the new zfs file system by using the zfs create -oshadow.


Explanation/Reference:Explanation:Migrating Data With ZFS Shadow MigrationZFS shadow migration is a tool you can use to migrate data from an existing file system to a new file system. A shadow file system is created that pulls data fromthe original source as necessary.

You can use the shadow migration feature to migrate file systems as follows:* A local or remote ZFS file system to a target ZFS file system* A local or remote UFS file system to a target ZFS file system

Shadow migration is a process that pulls the data to be migrated:* Create an empty ZFS file system.* Set the shadow property on an empty ZFS file system, which is the target (or shadow) file system, to point to the file system to be migrated.For example:# zfs create -o shadow=nfs://system/export/home/ufsdata users/home/shadow2* Data from file system to be migrated is copied over to the shadow file system.

Create the AI install service.Specify the path to the AI network boot image ISO file and the path where the AI net image ISO file should be unpacked.I. Create the AI install service. Specify the path to the AI network boot image ISO file and the path to the IPS repository.

Correct Answer: Section: (none)Explanation

Explanation/Reference:Answer: B,D,F,G,IExplanation:B:Configure the AI install server to use a static IP address and default route.D: The create-service command can set up DHCP on the AI install server. If you want to set up a separate DHCP server or configure an existing DHCP server foruse with AI. The DHCP server must be able to provide DNS information to the systems to be installed.E: An automated installation of a client over the network consists of the following high-level steps:

1. The client system boots over the network and gets its network configuration and the location of the install server from the DHCP server.

2. The install server provides a boot image to the client.

3. Characteristics of the client determine which installation instructions and which system configuration instructions are used to install the client.

4. The Oracle Solaris 11 OS is installed on the client, pulling packages from the package repository specified by the installation instructions in the AI install service.

G: Install the AI tool set.Use the installadm create-service command to create an AI install service. Give the service a meaningful name, and specify the path where you want the servicecreated. Specify the source of the network boot image (net image) package or ISO file.

installadm create-service [-n svcname][-s FMRI_or_ISO] [-d imagepath]

QUESTION 48United States of America export laws include restrictions on cryptography.


Identify the two methods with which these restrictions are accommodated in the Oracle Solaris 11 Cryptographic Framework.

A. Corporations must utilize signed X.509 v3 certificates.B. A third-party provider object must be signed with a certificate issued by Oracle.C. Loadable kernel software modules must register using the Cryptographic Framework SPI.D. Third-party providers must utilize X.509 v3 certificates signed by trusted Root Certification Authorities.E. Systems destined for embargoed countries utilize loadable kernel software modules that restrict encryption to 64 bit keys.

Correct Answer: BCSection: (none)Explanation


B: Binary Signatures for Third-Party SoftwareThe elfsign command provides a means to sign providers to be used with the Oracle Solaris Cryptographic Framework. Typically, this command is run by thedeveloper of a provider.

The elfsign command has subcommands to request a certificate from Sun and to sign binaries. Another subcommand verifies the signature. Unsigned binariescannot be used by the Oracle Solaris Cryptographic Framework. To sign one or more providers requires the certificate from Sun and the private key that was usedto request the certificate.

C: Export law in the United States requires that the use of open cryptographic interfaces be restricted. The Oracle Solaris Cryptographic Framework satisfies thecurrent law by requiring that kernel cryptographic providers and PKCS #11 cryptographic providers be signed.

QUESTION 50You are troubleshooting the Oracle Solaris11 Automated Installer (AI), which is not connecting with the IPS software repository.

Which three steps will help determine the cause of DNS name resolution failure?

A. Verify the contents of /etc/resolve.conf.B. Run netstat-nr to verify the routing to the DNS server.C. Ping the IP address of the IPS server to verify connectivity.D. On the installation server, verify that the menu.1st file for the client points to a valid boot arc hive.E. Run df-k to verify that the boot directory containing the boot archive is loopback mounted under /etc/netboot.F. Run the command /sbin/dhcpinfo DNSserv to ensure that the DHCP server providing the DNS server information.

Correct Answer: ABFSection: (none)Explanation

Explanation/Reference:Explanation:Check DNS* (A) Check whether DNS is configured on your client by verifying that a non-empty /etc/resolv.conf file exists.* (F) If /etc/resolv.conf does not exist or is empty, check that your DHCP server is providing DNS server information to the client:


# /sbin/dhcpinfo DNSservIf this command returns nothing, the DHCP server is not set up to provide DNS server information to the client. Contact your DHCP administrator to correct thisproblem.* (B) If an /etc/resolv.conf file exists and is properly configured, check for the following possible problems and contact your system administrator for resolution:**The DNS server might not be resolving your IPS repository server name.**No default route to reach the DNS server exists.

Zfs send pool1/data@Monday | ssh system zfs recv backup/mondayD. Zfs snapshot pool1/data@Monday | ssh system zfs recv backup/monday



Explanation/Reference:Explanation:Example (assuming there exists a snapshot `tank/test@1).Full backupNow let's do a full initial backup from the `tank/test@1 snapshot:# zfs send tank/test@1 | zfs receive tank/testback

QUESTION 52A change in your company's security policy now requires an audit trial of all administrators assuming the sysadm role, capturing:

There are two command necessary to accomplish this change. One is a rolemod command. What is the other?

A. auditconfig set policy=argvB. auditconfig-setpolicy +argvC. auditconfig-setflags lo, ex sysadmD. auditconfig set flags=lo, ex sysadm


Explanation/Reference:Explanation:Audit Significant Events in Addition to Login/Logout (see step 2 below) Use this procedure to audit administrative commands, attempts to invade the system, andother significant events as specified by your site security policy.

For all users and roles, add the AUE_PFEXEC audit event to their preselection mask.

# usermod -K audit_flags=lo,ps:no username# rolemod -K audit_flags=lo,ps:no rolename# auditconfig -setpolicy +argv3- Record the environment in which audited commands are executed.# auditconfig -setpolicy +arge

Note: [-t] -setpolicy [+|-]policy_flag[,policy_flag ...] Set the kernel audit policy. A policy policy_flag is literal strings that denotes an audit policy. A prefix of + adds thepolicies specified to the current audit policies. A prefix of - removes the policies specified from the current audit policies. No policies can be set from a local zoneunless the perzone policy is first set from the global zone.

QUESTION 55View the Exhibit to inspect the boot environment Information displayed within a non global zone on your system.

Which two options describe the solaris-1 boot environment?

A. The solaris-1 boot environment is not bootable.B. The solaris-1 boot environment is incomplete.C. The solaris-1 boot environment was created automatically when the non global zone was created.D. The solaris-1 boot environment was created in the non-global zone using the beadm create command.E. The solaris-1 boot environment is associated with a non active global zone boot environment.



Explanation/Reference:Explanation:A: The of the Active Column indicates that this boot environment is inactive, and hence not bootable.

Note: The values for the Active column are as follows:

R Active on reboot.

N Active now.

NR Active now and active on reboot.

"-" Inactive.

"!" Unbootable boot environments in a non-global zone are represented by an exclamation point.

D: beadm createCreates a new boot environment name, beName.

Note: beadm listLists information about the existing boot environment, which is beName, or lists information for all boot environments if beName is not provided.Note: Using beadm Utility (Tasks)You can use the beadm utility to create and manage snapshots and clones of your boot environments.Note the following distinctions relevant to boot environment administration:* A snapshot is a read-only image of a dataset or boot environment at a given point in time. A snapshot is not bootable.* A boot environment is a bootable Oracle Solaris environment, consisting of a root dataset and, optionally, other datasets mounted underneath it. Exactly one bootenvironment can be active at a time.* A clone of a boot environment is created by copying another boot environment. A clone is bootable.

QUESTION 56You are using AI to install a new system. You have added to following information to the AI manifest:

<configuration type= "zone" name= "dbzone"source = "http://sysA.example.com/zone_cfg/zone.cfg"/>


Which statement is true with regard to the zone.cfg?

A. The zone.cfg file is text file in a zonecfg export format.B. The zone.cfg file is an AI manifest that specifies how the zone is to be installed.C. The zone.cfg file is an xml file in a form suitable for use as a command file for the zonecfg command.D. The zone.cfg file is an SC profile with keywords that are specific for configuring a as part of the installation process.E. It is am xml configuration file from the /etc/zone directory. It will be used as a profile for the zone. It specifies the zonename, zonepath, and other zonecfg

parameters.


Explanation/Reference:Explanation:The configuration element supports non-global zone configurations. When installing a global zone system, the zone configurations specified in the AI manifest areused to install non-global zones onto the system after the global zone has been installed

The configuration element has the following attributes:

typeThe type of configuration to install. The only type supported by AI is zone.

nameA name given to the configuration. This name must be unique across all configuration elements in an AI manifest. For configurations of type zone, this name is alsoused as the zonename for the zone.

sourceThe location from which AI downloads the configuration file for this configuration element. The value can be an HTTP or FILE URI specification. For configurationsof type zone, this value should point to a zone configuration file as produced from the zonecfg export command.
