Question No: 3

You are using the limited scope multicast IP address 239.128.0.1 for a high volume data distribution

application. what symptom would you expect to find in the network?

A. The video traffic cannot be handled by a limited scope multicast address

B. There is no problem and the network is performing smoothly , just as designed

C. The high volume traffic is being sent to the 224.128.0.1 multicast address as well as on the original

address, causing high network load on all multicast subnets

D. The high volume application creates high network traffic load on all systems on the subnets where the video is being sent.

Question No: 6

Which two loops-prevention mechanisms are implemented in BGP? (Choose two)

A. The command bgp bestpath as-path-ignore enables the strict checking of AS_PATH so that they drop routes with their own AS in the AS_PATH.

B. A route with its own cluster ID in the CKUSTER_LIST is dropped automatically when the route reenters its own AS.

C. The command bgpbestpath med missing-as-worst assigns the smallest possible MED, which directly prevents a loop.

D. The command bgpallowa-in enables a route with its own AS_PATH to be dropped when it reenters its own AS

E. A route with its own AS in the AS_PATH is dropped automatically if the routereenters its own AS.
