Question 7

In a PIM sparse mode network, how to restore the flow of multicast traffic when a link fails along a branch of a multicast distribution tree?
A) The traffic reverts to the shared tree while the downstream router recalculates the RPF interface and sends a new PIM join message to the RP.
B) The downstream receivers notice the loss of the multicast flow and resend PIM join messages to reestablish the tree.
C) The downstream receivers notice the loss of the multicast flow and resend IGMP Membership Reports to reestablish the tree.
D) The router downstream of the break recalculates the RPF interface when it notices a change in the unicast routing table and immediately sends a new PIM join message out from the new RPF.

Accepted Answer

When a link fails, the downstream router recalculates the Reverse Path Forwarding (RPF) interface based on the updated unicast routing table and sends a new PIM join message to reestablish the multicast distribution tree.

A) It is independent of the routed protocol.
B) It offloads routing between sites to the service provider.
C) It improves routing protocols and network convergence.
D) It allows for transparent routing across the service provider.

MPLS-based L3VPN service allows the service provider to manage routing between customer sites, simplifying the customer's network management.

Question 11

Which description is true about downstream suppression?
A) the ability of a fault management tool to generate alerts for only an upstream device failure and to suppress the alarms related to all unreachable downstream sites
