19 表單的頂端In what two ways will entering into a managed service agreement with an ISP for a network upgrade affect the costs that are incurred by the customer? (Choose two.)

Customer IT training costs will increase to enable operation of the new equipment.The cost of hardware repairs and support will become the responsibility of the customer.Network upgrade and maintenance costs will become predictable.Staffing costs will increase because the customer will need to hire additional IT staff to complete the upgrade.The company will not need to spend a large amount of money to purchase the equipment upfront.

20 表單的頂端What is the benefit for a company to use an ISR router?

An ISR provides the functionality of a switch, router, and firewall in one device.ISRs use a PC operating system for routing traffic, thus simplifying configuration and management.An ISR is immune to security attacks by hackers and so replaces all other network security measures.ISRs make routing decisions at OSI Layer 7, thus providing more intelligence to the network than

do other routers.
