Question: 1

Which two commands are required to enable multicast on a router, knowing that the receivers only support IGMPv2? (Choose two.)

A. ip pim rp-address

B. ip pim ssm

C. ip pim sparse-mode

D. ip pim passive

Answer: AC

Question: 2

A branch router is configured with an egress QoS policy that was designed for a total number of 10 concurrent VOIP calls. Due to expansion, 15 VOIP calls are now running over the link, but after the 14th call was established, all calls were affected and the voice quality was dramatically degraded. Assuming that there is enough bandwidth on the link for all of this traffic, which part of the QoS configuration should be updated due to the new traffic profile?

A. Increase the shaping rate for the priority queue.

B. Remove the policer applied on the priority queue.

C. Remove the shaper applied on the priority queue.

D. Increase the policing rate for the priority queue.

Answer: D

Question: 3

A new backup connection is being deployed on a remote site router. The stability of the connection has been a concern. In order to provide more information to EIGRP regarding this interface, you wish to incorporate the “reliability” cost metric in the EIGRP calculation with the command metric   weights 1 0 1 0 1.

What impact will this modification on the remote site router have for other existing EIGRP neighborships from the same EIGRP domain?

A. Existing neighbors will immediately begin using the new metric.

B. Existing neighbors will use the new metric after clearing the EIGRP neighbors.

C. Existing neighbors will resync, maintaining the neighbor relationship.

D. All existing neighbor relationships will go down.

Answer: D

Question: 4

Refer to the exhibit. R1 has an EBGP session to ISP 1 and an EBGP session to ISP 2. R1 receives the same prefixes through both links.

Which configuration should be applied so that the link between R1 and ISP 2 will be preferred for outgoing traffic (R1 to ISP 2)?

A. Increase local preference on R1 for received routes

B. Decrease local preference on R1 for received routes

C. Increase MED on ISP 2 for received routes

D. Decrease MED on ISP 2 for received routes

Answer: A

Question: 5

Refer to the exhibit. A small enterprise connects its office to two ISPs, using separate T1 links. A static route is used for the default route, pointing to both interfaces with a different administrative distance, so that one of the default routes is preferred. Recently the primary link has been upgraded to a new 10 Mb/s Ethernet link. After a few weeks, they experienced a failure. The link did not pass traffic, but the primary static route remained active. They lost their Internet connectivity, even though the backup link was operating.

Which two possible solutions can be implemented to avoid this situation in the future? (Choose two.)

A. Implement HSRP link tracking on the branch router R1.

B. Use a track object with an IP SLA probe for the static route on R1.

C. Track the link state of the Ethernet link using a track object on R1.

D. Use a routing protocol between R1 and the upstream ISP.
