Question 2

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?

  • 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.
Mark Question:
Answer:

C


Explanation:
For those asking about the password, area authentication doesn't prevent neighboring to come up
because it is carried only in LSP, CSNP and PSNP messages and not in IIH messages.

Question 4

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?

  • 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

Question 5

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?

  • 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
Mark Question:
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 6

Refer to the exhibit.

After troubleshooting an OSPF adjacency issue, routers 1, 2, and 3 have formed OSPF
neighbor relationships. Which statement about the configuration is true?

  • A. Router 2 receives a Type 5 LSAs from router 1 for its connected subnets
  • B. Router 2 uses router 3 as the next hop for 192.168.0.0/24
  • C. Router 2 uses router 1 as the next hop for 192.168.0.0/24
  • D. Router 2 receives a Type 7 LSAs from router 3 for its connected subnets
Mark Question:
Answer:

C


Explanation:
From IOS 15.1(2)S onwards, Cisco uses the OSPF path selection order is O > O IA > N1 > E1 > N2 > E2
