The exhibit shows part of the configuration for a router. You receive a complaint that the router is
not correctly reclassifying all traffic to the best-effort forwarding class when the amount of IPv4
traffic exceeds 10 Mbps.

You have isolated the problem to traffic with the IP precedence bits set to the binary value 101.
Which configuration is causing this behavior?

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?

You add a multicast source to a network. The source’s DR sends register messages to the RP
However, multicast clients are not able to receive traffic from the source. What are two causes of
this problem? (Choose two.)

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.)

You are troubleshooting a problem where external routes are not being summarized into the OSPF backbone.

Referring to the exhibit, what needs to be done to resolve this problem?

Referring to the exhibit, an administrator has configured dot1q-tunneling on the VLAN, but
LLDP is not being tunneled.

What is causing the problem?

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?

Interface ge-0/0/12 on Switch1 is connected to ge-0/0/12 on Switch2. You have configured both
Switch1 and Switch2 to run MSTP. You see the CLI output shown in the exhibit.

What would cause this output?

Referring to the exhibit, an administrator notices that the VLAN interface is not coming up. What
would cause this problem? Click the Exhibit to see a larger version.

You have configured OSPF between two routers and the adjacency is not coming up. You confirm
that the physical link between them is up and then run the commands shown in the exhibit on both routers.

Which two configuration mistakes apply? (Choose two.)
