Company XYZ wants to use the FCAPS ISO standard for network management design. The focus of the

design should be to monitor and keep track of any performance issues by continuously collecting and

analyzing statistical information to monitor, correct, and optimize any reduced responsiveness across the

network. Which layer accomplishes this design requirement?

When designing a network, which two security features should be added to the design to protect hosts from potential IPv6 neighbor discovery denial of service attacks at the access layer? (Choose two.)

What is a correct design consideration of IPv6 MLD snooping?

A large service provider network has a single-level IS-IS network with 500 routers. This network has short-haul and long-haul links. Periodically, long-haul links bounce for a short period of time, causing 10 to 20 flaps in a few minutes. The probable cause is local road construction. Although fast convergence is important, a design engineer is concerned about taxing CPU cycles on the older routers. Which solution protects the CPU of the older routers during the short periods of excessive flapping, yet has no impact on fast convergence for all interface failures?
