• Question 183:

  A network architect dides to expand the scope of the multicast deployment within the company network the network is already using PlM-SM with a static RP that supports a high-bandwidth. video-based training application that s heavily used by the employees, but excessive bandwidth usage is a concern.

  How must the engineer update the network to provide a more efficient multicast implementation'?

  A. Configure IGMP to manage the multicast hosts on each LAN

  B. implement BSR to support dynamic RP notification.

  C. Deploy ICMP to Improve multicast reachability across the network using static RP.

  D. Implement STP to improve switching performance for multicast data.

  Correct Answer: B

• Question 184:

  Refer to the exhibit.

  

  An organization s network recently experienced several significant outages due to device failures. The network administrator just moved the network devices to a new central data center, and packets are switched using labels. The administrator Is now implementing NSF on the network to reduce potential risk factors in the event of another outage.

  Which task must the administrator perform on each router as part of the process?

  A. Remove route filtering to speed repopulation of the link-state database

  B. Copy the router s existing state information and share the file with its peers to enable BGP soft resets

  C. Implement MPLS to forward packets while the RIB updates after a faliover.

  D. Implement Graceful Restart to mitigate the delay in MPLS LDP synchronization when the IGP starts up.

  Correct Answer: D

• Question 185:
