Nokia IS-IS Routing Protocol Sample Questions (Q31-Q36):

NEW QUESTION # 31
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. Control Processing Module (CMP)
  • B. Switch Fabric (SF)
  • 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 # 32
A new router is added to a broadcast network. What does IS-IS use as the tiebreaker for selecting the DIS if the priorities are the same?

  • A. The Hello packet with the highest sequence number.
  • B. The router with the highest system ID.
  • C. The existing DIS remains the DIS.
  • D. The router with the highest interface MAC address.

Answer: B

Explanation:
In IS-IS, the Designated Intermediate System (DIS) is responsible for certain tasks on broadcast networks, such as generating link-state advertisements and acting as the central point for flooding information.


NEW QUESTION # 33
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. There is no route leaking configured on router R1 or router R2.
  • B. Route leaking is configured on router R1 but not on router R2.
  • C. Route leaking is configured on both routers R1 and R2.
  • D. Route leaking is configured on router R2 but not on router R1.

Answer: C

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 # 34
For a link-state routing protocol, which of the following statements about link-state updates is FALSE?

  • A. When a router detects that a link-state update has reached its maximum age, it will request a new update from the source router.
  • B. The age value is updated as the link-state update is flooded throughout the network and when it is in the link-state database
  • 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 # 35
Which of the following statements about router interfaces on a Nokia 7750 SR is FALSE?

  • A. They can be used in pairs on the same subnet for redundancy.
  • B. They can be logical or physical.
  • C. The system interface exists by default.
  • D. They can be assigned IPv4 and/or IPv6 addresses.

Answer: A

Explanation:
Typically, interfaces on a Nokia 7750 SR router are not configured in pairs on the same subnet for redundancy. Instead, redundancy is achieved through mechanisms like Virtual Router Redundancy Protocol (VRRP) or other high availability protocols, not by simply using interfaces in pairs on the same subnet.
