Question # 4

Drag the fast Reroute mechanism on the left and drop it onto the corresponding routing protocol on the right

Question # 5

You are redesigning a single-level IS-IS network with 500 routers, which have short-haul and long-haul links Most of the time the routing domain is stable, but periodically interfaces on 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 important, the client has concerns about taxing CPU cycles on the older routing platforms. What change should you recommend that both protects the CPU of the older routers during the short periods of excessive flapping, yet does not have an impact on fast convergence for all interface failures?

A.

Modify hello timers on routers with short-haul links

B.

Implement LSP generation throttling on routers with long-haul links

C.

Modify the length of time than an LSP remains in the router database without being refreshed on all routers

D.

Implement a delay between successive IS-IS LSP packet transmissions on routers with long-haul links

Question # 6

What is an implication of using route reflectors in an iBGP topology?

A.

Route reflection limits the total number of iBGP routers.

B.

Route reflection causes traffic to flow in a hub-and-spoke fashion.

C.

The manipulation of BGP attributes is not supported on the other routers than the route reflectors.

D.

Route reflectors can create routing loops when more than one router reflector is used in the same cluster.

E.

Multipath information is difficult to propagate in a route reflector topology.

C.

CE devices that run OSPF clear the DN bit toward the PE router

D.
