Refer to the exhibit.
All connections between switches are 10 Gbps. Switch is an Intelligent Resilient Framework (IRF)
group with two member. Switch2 is an IRF group with two members. Switch1 and Switch2 route all
traffic.
A network architect is designing a solution for a finance company. One of the primary applications
is a multicast application that delivers stock information to IP video screens across the site. The
network architect is seeking a multicast solution that meets these needs:
Simple configuration that the customer’s IT staff can manage and troubleshoot
No single point of failure for the multicast traffic
What is the best solution for this environment and these needs?
A.
Protocol Independent Multicast (PIM) Dense Mode (DM).
B.
Protocol Independent Multicast (PIM) Sparse Mode (SM) with switch 1 and switch 2 configured
as candidate Rendezvous Points (C-RPs), and switch1 and Switch2 also configured as Bootstrap
Router (BSRs).
C.
Protocol Independent Multicast (PIM) Dense Mode (DM) with Switch1 and Switch2 set as the
DM Master Router. Switch1 has a higher MR priority for an address associated with the multicast
application.
D.
Protocol independent Multicast (PIM) Sparse Mode (SM) with switch1 and Switch2 set as the
static Rendezvous Points (RPs). Switch1 has a higher RP priority for an address associated with
the multicast application.
Explanation:
correct answer is A
Advantages of PIM-DM include:
– It is simpler to set up.
– It does not have any points of failure besides the points of failure in the routing system.
Disadvantages of PIM-SM include:
– It is more complicated to set up.
– RPs can be points of failure. However, a system can include multiple candidate RPs (C-RPs) to provide resiliency.
