Nokia IS-IS Routing Protocol Sample Questions (Q18-Q23):

NEW QUESTION # 18
A router running a link-state routing protocol detects that one of its neighbors is no longer connected to it. The router generates a new link-state advertisement to inform other routers of the topology change. Which of the following is NOT an action that is triggered by this event?

  • A. If a router receives multiple copies of the new link-state advertisement, it will simply ignore all copies received after the first one.
  • B. If a router receives the new link-state advertisement, it acknowledges it, stores it, and forwards it to its own neighbors.
  • C. Every router that receives the new link-state advertisement runs the SPF algorithm to recalculate its shortest-path tree and its forwarding database.
  • D. Every router that receives the new link-state advertisement updates its age field before forwarding it.

Answer: D

Explanation:
When a router receives a link-state advertisement (LSA), it does not update the age field before forwarding it. The age field in an LSA is typically updated by the originating router or during the process of forwarding the LSA within the network. Routers do not modify the age field upon receiving and forwarding an LSA.


NEW QUESTION # 19
Refer to the exhibit.

In the IS-IS network shown, router R1 has been configured to summarize subnetworks 20.20.1.0/24 and 20.20.2.0/24 as 20.20.0.0/16. Which routers' routing tables will be reduced, compared to their routing tables before the summarization?

  • A. Routers R1 and R2
  • B. Router R2
  • C. Routers R2 and R4
  • D. Router R1

Answer: B

Explanation:
Router R1 is the one that performs the summarization of the two subnets (20.20.1.0/24 and 20.20.2.0/24) into the summarized route 20.20.0.0/16. However, R1 itself will not see any change in its routing table because it is directly connected to both subnets and already knows about them.
Router R2, which is in Area 49.0002, will benefit from this summarization because it previously had separate routes for both 20.20.1.0/24 and 20.20.2.0/24. After the summarization, R2 will only need to maintain a single route to 20.20.0.0/16, reducing the size of its routing table.
Router R4 does not directly benefit from the summarization because it is only connected to the Level 1 network and has no need for the summarized routes from R1. Thus, the summarization does not affect R4's routing table.


NEW QUESTION # 20
Which component of the Nokia 7750 SR is in charge of performing the longest prefix match lookup on packets that arrive on the physical interfaces?

  • A. Switch Fabric (SF)
  • B. Control Processing Module (CMP)
  • C. Input/Output Module (IOM)
  • D. Media Dependent Adapter (MDA)

Answer: C

Explanation:
The Input/Output Module (IOM) is responsible for performing the longest prefix match (LPM) lookup on packets that arrive at the physical interfaces. The IOM performs this function by examining the destination IP address of incoming packets and using the routing table to determine the best match.


NEW QUESTION # 21
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 router R1 but not on router R2.
  • B. Route leaking is configured on both routers R1 and 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: B

Explanation:
From the route tables of R3 and R4, we can see that remote routes are present, with R3 and R4 both having routes referencing routers in different areas (Area 49.01 and 49.02). These remote routes are characteristic of route leaking, which is the process of sharing routes between different IS-IS areas.
R3 has routes for R1, R2, and R4, which are in Area 49.01, suggesting that R1 and R2 have advertised their routes to R3, possibly due to route leaking.
R4 has similar routes for R2 and R3, indicating that R2 might have advertised its routes to R4.
This sharing of routes between areas is indicative of route leaking being configured on both R1 and R2, allowing these routes to be shared across the areas.


NEW QUESTION # 22
Refer to the exhibit.

In the diagram, all routers are using IS-IS as their routing protocol. The number next to each link is its metric value.
What path will traffic follow from router R6 to router R3, and from router R3 to router R6?

  • A. Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3-R4-R2-R5-R6).
  • B. Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3-R4-R7-R5-R6).
  • C. Router R6 to router R3 will follow (R6-R5-R7-R4-R3). Router R3 to router R6 will follow (R3-R4-R7-R5-R6).
  • D. Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3-R2-R5-R6).

Answer: D

Explanation:
The metric values between the routers dictate the routing paths, and IS-IS will calculate the shortest path based on these values.
R6 to R3: The path from R6 to R3 will go through R5 and R2, as this route has the least cumulative metric (10 + 10 + 15 = 35).
R3 to R6: The reverse path from R3 to R6 will follow R3 → R2 → R5 → R6 because this route is also the shortest with a total metric of 10 + 10 + 10 = 30.


NEW QUESTION # 23
