Question 1 of 111

Refer to the exhibit. Which tree does multicast traffic follow?

shared tree

MDT default

source tree

MDT voice

Correct Answer: B

Question 2 of 111

Refer to the exhibit. After you applied these configurations to routers R1 and R2, the two devices could not form a neighbor relationship. Which reason for the problem is the most likely?

The two routers cannot authenticate with one another.

The two routers have the same area ID.

The two routers have the same network ID.

The two routers have different IS-types.

Correct Answer: C

The two routers cannot form a neighbor relationship because they have the same network ID. In Integrated IS-IS, neighbors must have different network IDs to establish a relationship. The network ID is a unique identifier for each router, and having the same ID can cause conflicts that prevent the establishment of an adjacency. Therefore, the most likely reason for the problem is the matching network IDs.

Question 3 of 111

Refer to the exhibit. Which effect of this configuration is true?

It sets the keepalive timer to 30 seconds and the hold timer to 240 seconds.

It sets the keepalive timer to 30 milliseconds and the hold timer to 240 milliseconds

It sets the hold timer to 30 milliseconds and the keepalive timer to 240 milliseconds

It sets the hold timer to 30 seconds and the keepalive timer to 240 seconds

Correct Answer: A

The command 'timers bgp 30 240' in the configuration sets the BGP (Border Gateway Protocol) keepalive timer to 30 seconds and the hold timer to 240 seconds. The keepalive timer specifies how often keepalive messages are sent to ensure the connection is still alive, and the hold timer is the maximum time the router waits to receive a keepalive message before considering the connection as down. Therefore, the correct effect of this configuration is that the keepalive timer is set to 30 seconds and the hold timer is set to 240 seconds.

Question 4 of 111

Refer to the exhibit. A network operator is working to filter routes from being advertised that are covered under an aggregate announcement. The receiving router of the aggregate announcement block is still getting some of the more specific routes plus the aggregate. Which configuration change ensures that only the aggregate is announced now and in the future if other networks are to be added?

Configure the summary-only keyword on the aggregate command

Set each specific route in the AGGRO policy to drop instead of suppress-route

Filter the routes on the receiving router

Set each specific route in the AGGRO policy to remove instead of suppress-route

Correct Answer: A

To ensure that only the aggregate route is announced and no specific routes are being leaked, the 'summary-only' keyword should be configured on the aggregate command. This option helps to suppress the advertisement of all more specific routes that are part of the aggregate. This method is effective now and will continue to be effective in the future if other networks are added under the aggregate.

Question 5 of 111

Refer to the exhibit. A network operator is getting the route for 10.11.11 0/24 from two upstream providers on #XR3. The network operator must configure #XR3 to force the 10.11.11.0/24 prefix to route via next hop of 10.0.0.9 as primary when available. Which of these can the operator use the routing policy language for, to enforce this traffic forwarding path?

weight of 0 on the prefix coming from 192.168.0.2

lower local preference on the prefix coming from 192.168.0.2

higher local preference on the prefix coming from 192.168.0.1

weight of 100 on the prefix coming from 192.168.0.1

Correct Answer: A

Weight is the first attribute in the BGP path selection process. Since the prefix from 192.168.0.2 already has a weight of 651, setting its weight to 0 would ensure that the router will prefer the prefix from 192.168.0.1 regardless of other attributes. This will force the 10.11.11.0/24 prefix to route via the next hop of 10.0.0.9, making it the primary path when available.
