Question #6 (Topic: )
You are monitoring a network that is configured with PIM sparse mode. An end user's PC
(PC1) joins a multicast stream. The stream never switches from the rendezvous-point tree
(RPT) to the shortest-path tree (SPT).
Which two statements explain this behavior? (Choose two.)
(PC1) joins a multicast stream. The stream never switches from the rendezvous-point tree
(RPT) to the shortest-path tree (SPT).
Which two statements explain this behavior? (Choose two.)
A. An interface on the SPT is not configured for PIM.
B. The designated router for PCI's LAN does not have a route to the multicast source.
C. This is the normal operation of PIM sparse mode.
D. This is a source-specific multicast (SSM) stream.
Answer: A,B

-- Exhibit --
Click the Exhibit button.
Your network has two connections to your ISP. You have been asked to load-balance
traffic across both links that connect to your ISP. You have enabled multipath for this peer,
but you are still not getting the expected load balancing.
Given the information shown in the exhibit, what else must you do?

but you are still not getting the expected load balancing.
Given the information shown in the exhibit, what else must you do?
A. Configure and apply a load-balancing policy.
B. Change the multipath parameter to multihop.
C. Create a policy to manually change the next hops.
D. Enable the keep all parameter.
Answer: A
Question #8 (Topic: )
You are asked to troubleshoot a problem with MSTP and determine why Switch-1 and
Switch-2 think they are the root bridge for the same MSTI instances. Switch-1 should be
the root bridge for the MSTI 1 instance and Switch-2 should be the root bridge for the MSTI
2 instance. Referring to the exhibit, what is causing this problem?

A. The configuration digest is misconfigured.
B. Both switches have the same bridge priority.
C. The member VLAN assignments are not identical.
D. The revision levels are identical.
Answer: C
Question #9 (Topic: )
Two neighboring routers are able to form an OSPF adjacency, but are not able to establish
an IBGP neighborship.
What are two reasons for the IBGP neighborship problem? (Choose two.)
an IBGP neighborship.
What are two reasons for the IBGP neighborship problem? (Choose two.)
A. One of the devices has a misconfigured BGP peer address.
B. One or both of the connected interfaces are missing the family iso statement.
C. OSPF has a lower route preference than BGP.
D. A firewall filter on one of the interfaces is blocking TCP traffic.
Answer: B,C
Question #10 (Topic: )
There is a lot of traffic marked with IP precedence values af2l and af3l that ingresses the
router. The af3l traffic should be using the expedited forwarding queue, but the traffic is
much lower than expected and there are no drops seen on the egress interface.

Referring to the exhibit, what is causing the problem?
A. The assured forwarding queue has a strict high priority and is starving the expedited forwarding queue.
B. The expedited forwarding queue has a low priority value; therefore the traffic is not serviced.
C. The MF classifier is forwarding most of the af3l traffic to the best-effort queue.
D. The MF classifier is does not match on af3l and therefore the traffic is being dropped.
Answer: C
