300-510 Cisco Practice Questions

Question #1 (Topic: demo questions)

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?

A.

weight of 0 on the prefix coming from 192.168.0.2

B.

lower local preference on the prefix coming from 192.168.0.2

C.

higher local preference on the prefix coming from 192.168.0.1

D.

weight of 100 on the prefix coming from 192.168.0.1

Correct Answer: A

Explanation:

Because Weight is the first attribute in path selection algorithm and is 0 for eBGP routes by default. If we set it to 0, router will continue from weight to the bottom, and when comparing neighbor router IDs it will find 192.168.0.1 less than 192.168.0.2 and st path will be selected as the best

Question #2 (Topic: demo questions)

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?

A.

Configure the summary-only keyword on the aggregate command

B.

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

C.

Filter the routes on the receiving router

D.

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

Correct Answer: A

Question #3 (Topic: demo questions)

Which effect of this configuration is true?

A.

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

B.

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

C.

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

D.

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

Correct Answer: A

Question #4 (Topic: demo questions)

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?

A.

The two routers cannot authenticate with one another.

B.

The two routers have the same area ID.

C.

The two routers have the same network ID.

D.

The two routers have different IS-types.

Correct Answer: C

B.

C.

source tree

D.
