Learn About Cisco Exam 642-892: CCNP Composite

The following are questions from MeasureUp Practice Test for the Cisco exam 642-892: CCNP Composite

The audience for this exam includes individuals who are responsible for implementing multilayer switched networks and for configuring Cisco ISR routers to ensure the LANs and WANs to which they are connected are scalable. Experience with configuring, supporting and securing routing protocols, VLANs, IP multicasting, IPv6, wireless clients and voice networks will help you prepare for this exam.

Objective: Implement multicast forwarding.
Sub-objective: Describe, configure or verify IP multicast routing (e.g., PIM Sparse-Dense Mode).

Single answer, multiple-choice

Which command should you use so the router sends an auto-RP message to the address announcing that it is a candidate rendezvous point?

A.    ip pim send-rp-discovery
B.    ip pim send-rp-announce
C.    ip pim spt-threshold
D.    ip pim sparse-mode

The ip pim send-rp-announce global configuration command is used on a router, so it sends an auto-RP message to announcing it is a candidate RP for the group.

The ip pim send-rp-discovery global configuration command configures a router as an RP mapping agent.

The ip pim spt-threshold global configuration command controls when the Protocol Independent Multicast (PIM) leaf router will switch over from the shared tree to the source tree in sparse mode.

The ip pim sparse-mode interface configuration command enables PIM-SM (sparse mode) operation on an interface.
