Nokia IS-IS Routing Protocol Sample Questions (Q39-Q44):

NEW QUESTION # 39
For a link-state routing protocol, which of the following statements about link-state updates is FALSE?

  • A. The age value is updated as the link-state update is flooded throughout the network and when it is in the link-state database
  • B. When a router detects that a link-state update has reached its maximum age, it will request a new update from the source router.
  • C. When a link-state update reaches its maximum age on a router, the router will flood that update to its neighbors.
  • D. Aging helps ensure that routers that are no longer part of the topology will eventually get removed from the link-state database.

Answer: C

Explanation:
When a link-state update reaches its maximum age, it is removed from the router's link-state database, not flooded to its neighbors. This prevents outdated information from continuing to affect the routing decisions. The router does not flood the aged update; instead, it will typically request a new link-state advertisement from the original source router if the information is still needed.


NEW QUESTION # 40
Refer to the exhibit.

Routers R1 through R4 are running an IGP in such a way that they have each other's system IP addresses in their routing tables. A static route is configured on router R1 so that it can reach subnetwork 10.4.100.0/24. The network administrator decides to use an indirect static route, as shown in the diagram. However, pinging the server from router R1 fails. What may be the problem in this case?

  • A. The echo request arrives at the server but there is no path for the echo response to return to router R1.
  • B. Router R1 drops the echo request because address 10.10.10.3 does not belong to an adjacent router.
  • C. Router R2 drops the echo request because it does not have subnet 10.4.100.0/24 in its routing table.
  • D. Router R3 drops the echo request because it does not have subnet 10.4.100.0/24 in its routing table.

Answer: A

Explanation:
The static route configured on router R1 uses an indirect next-hop, which is 10.10.10.3 (R3). While the echo request from R1 reaches the server through the IGP, the problem lies in the return path for the echo response.
The route 10.4.100.0/24 is reachable through R3, but there is no reciprocal route in R3's routing table that allows the response to flow back towards R1. This results in a failure to return the echo response to R1, causing the ping to fail.


NEW QUESTION # 41
Consider the exhibit.

All routers are running IS-IS with IPv6 support enabled. Based on the topology shown, and the route tables of routers R3 and R4, which of the following statements is TRUE?

  • A. Route leaking is configured on both routers R1 and R2.
  • B. Route leaking is configured on router R1 but not on router R2.
  • C. There is no route leaking configured on router R1 or router R2.
  • D. Route leaking is configured on router R2 but not on router R1.

Answer: A

Explanation:
Based on the IPv6 route table output for R3 and R4, we can see that the routers have remote routes listed as "Remote ISIS", indicating that the route is being advertised from a different area (area 49.01 or 49.02). This is a sign of route leaking, where routes from one area are being shared across areas.
The routes from R3 (level-1 router) are being advertised to R4 (level-1 router), and vice versa, with ISIS as the protocol. This implies that there is route leaking configured to allow information to pass between areas.


NEW QUESTION # 42
Refer to the exhibit.

Which of the following statements best describes the IS-IS domain to which the command output corresponds?

  • A. Single-area IS-IS domain with broadcast interfaces.
  • B. Multi-area IS-IS domain with broadcast interfaces.
  • C. Multi-area IS-IS domain with no broadcast interfaces.
  • D. Single-area IS-IS domain with no broadcast interfaces.

Answer: B

Explanation:
The output shows two levels of IS-IS databases: Level 1 (L1) and Level 2 (L2). This indicates that the domain is multi-area, as L1 routers are confined to a single area, while L2 routers can route between different areas. The presence of Level 1/Level 2 (L1/L2) routers also suggests that the domain spans multiple areas.
The LSP (Link-State PDU) entries show L1/L2 ATT attributes, which typically indicate that these routers are capable of routing both within their own area (Level 1) and across areas (Level 2), suggesting a multi-area design.
The IS-IS domain likely includes broadcast interfaces, as indicated by the "ATT" attribute (typically referring to the type of interface) and common IS-IS configuration practices on broadcast networks like Ethernet.


NEW QUESTION # 43
Refer to the exhibit.

Routers R1, R2, R3, and R4 are running IS-IS. Assuming all interfaces are added to IS-IS as point-to-point and no commands are issued at the interface level to restrict adjacencies, which of the following statements is TRUE?

  • A. Routers R1 and R2 are L2 routers. Routers R3 and R4 are L1 routers.
  • B. Routers R1 and R2 are L1/L2 routers. Routers R3 and R4 are L1 routers.
  • C. All four routers are L1/L2.
  • D. Routers R1 and R2 are L2 routers. Routers R3 and R4 are L1/L2 routers.

Answer: B

Explanation:
From the output, we can see that the usage column indicates whether a router is operating as an L1 or L2 router:
The L1/L2 designations refer to whether the routers participate in both Level 1 and Level 2 of IS-IS:
In this case, R1 and R2 are L2 routers, and R3 and R4 are L1 routers.
