PAP conducts periodic password challenges.

PAP uses MD5 hashing to keep the password secure.

15. What is an accurate description of CHAP when used with PPP on a serial connection between two

routers?

A username and password are sent to the peer router, which replies with an accept or reject message.

A username and password are sent to the peer router. If these match the configuration in the peer, the peer in turn

provides a username and password to the initiating router.

A challenge message is sent to the peer router, which responds with its username and a calculated value based

on a shared secret. This value is then compared by the challenger to its own calculations.

An encrypted password is sent to the peer router, which decrypts it and compares it to a shared secret. If the

decrypted passwords match, the peer sends the encrypted password back to the initiating router.

40. Refer to the exhibit. Which statement correctly describes how Router1 processes an FTP request packet

that enters interface S0/0/0, and is destined for an FTP server at IP address 172.16.1.5?

The router matches the incoming packet to the statement that is created by access-list 201 permit ip any any

command and allows the packet into the router.

The router reaches the end of ACL 101 without matching a condition and drops the packet because there is no

statement that was created by access-list 101 permit ip any any command.

The router matches the incoming packet to the statement that was created by the access-list 101 permit ip any

172.16.1.0 0.0.0.255 command, ignores the remaining statements in ACL 101, and allows the packet into the

router.

The router matches the incoming packet to the statement that was created by the access-list 201 deny icmp

172.16.1.0 0.0.0.255 any command, continues comparing the packet to the remaining statements in ACL 201 to

ensure that no subsequent statements allow FTP, and then the router drops the packet.

26

Refer to the exhibit. Which statement correctly describes how Router1 processes an FTP

request packet that enters interface S0/0/0, and is destined for an FTP server at IP address

172.16.1.5?

The router matches the incoming packet to the statement that is created by access-list 201

permit ip any any command and allows the packet into the router.

The router reaches the end of ACL 101 without matching a condition and drops the packet

because there is no statement that was created by access-list 101 permit ip any any

command.

***The router matches the incoming packet to the statement that was created by the

access-list 101 permit ip any 172.16.1.0 0.0.0.255 command, ignores the remaining

statements in ACL 101, and allows the packet into the router.

The router matches the incoming packet to the statement that was created by the access-

list 201 deny icmp 172.16.1.0 0.0.0.255 any command, continues comparing the packet to

the remaining statements in ACL 201 to ensure that no subsequent statements allow FTP,

and then the router drops the packet.

Refer to the exhibit. Partial results of the show access-lists and show ip interface FastEthernet 0/1 commands for router Router1 are shown. There are no other ACLs in effect. Host A is unable to telnet to host B.

Which action will correct the problem but still restrict other traffic between the two networks?



***Reverse the order of the TCP protocol statements in the ACL.


44Which combination of Layer 2 protocol and authentication should be used to establish a link without sending authentication information in plain text between a Cisco and a non-Cisco router?

PPP with PAP

***PPP with CHAP

HDLC with PAP

HDLC with CHAP

45Which Frame Relay flow control mechanism is used to signal routers that they should reduce the flow rate of frames?

DE

BE

CIR

***FECN

CBIR

46Which three guidelines would help contribute to creating a strong password policy? (Choose three.)


***Deliberately misspell words when creating passwords.

***Create passwords that are at least 8 characters in length.

47An administrator is configuring a dual stack router with IPv6 and IPv4 using RIPng. The administrator receives an error message when trying to enter the IPv4 routes into RIPng. What is the cause of the problem?

When IPv4 and IPv6 are configured on the same interface, all IPv4 addresses are over-written in favor of the newer technology.

Incorrect IPv4 addresses are entered on the router interfaces.


***IPv4 is incompatible with RIPng.

48When would the multipoint keyword be used in Frame Relay PVCs configuration?

when global DLCIs are in use

when using physical interfaces

when multicasts must be supported

***when participating routers are in the same subnet

49A network administrator is tasked with maintaining two remote locations in the same city. Both locations use the same service provider and have the same service plan for DSL service. When comparing download rates, it is noticed that the location on the East side of town has a faster download rate than the location on the West side of town. How can this be explained?

The West side has a high volume of POTS traffic.

The West side of town is downloading larger packets.

***The service provider is closer to the location on the East side.

More clients share a connection to the DSLAM on the West side.

50

Which two statements are true about IPv6 link local addresses? (Choose two.)

***They begin with the 2000::/3 prefix.

They begin with the FE80::/10 prefix.

***They are assigned by IANA to an organization.

They must be manually configured by the administrator.

They are assigned to a host by a stateless autoconfiguration process.

51What is tunneling?

using digital certificates to ensure that data endpoints are authentic

creating a hash to ensure the integrity of data as it traverses a network

using alternate paths to avoid access control lists and bypass security measures

encapsulating an entire packet within another packet for transmission over a network
