Nokia IS-IS Routing Protocol Sample Questions (Q23-Q28):

NEW QUESTION # 23
Refer to the exhibit.

Routers R1 through R4 in the diagram have established IS-IS adjacencies. Router R1 is L1/L2 and is the DIS of its two broadcast interfaces. How many LSPs will it generate?

A. 0
B. 1
C. 2
D. 3

Answer: B

Explanation:
Router R1 is configured as L1/L2, meaning it is part of both Level 1 and Level 2 IS-IS routing areas. This means R1 will generate two types of LSPs:
Level 1 LSP (for the local area 49.0001) to advertise its local topology to other Level 1 routers.
Level 2 LSP (for the backbone area 49.0002) to advertise the global network topology to Level 2 routers.
R1 also has two broadcast interfaces, and as the Designated Intermediate System (DIS) on these interfaces, it will generate an LSP for each interface (one per broadcast link).
This results in three total LSPs:
A Level 1 LSP for the local area (49.0001).
A Level 2 LSP for the backbone area (49.0002).
An LSP for each of the two broadcast interfaces, which may include interface-related topology information.

NEW QUESTION # 24
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 router with the highest interface MAC address.
B. The Hello packet with the highest sequence number.
C. The router with the highest system ID.
D. The existing DIS remains the DIS.

Answer: C

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 # 25
When multiple routing protocols offer a route for the same prefix, what part of the router is in charge of deciding which route to make active?

A. The routing table manager (RTM)
B. The routing information base (RIB)
C. The equal cost multipath configuration
D. The forwarding information base (FIB)

Answer: A

Explanation:
The routing table manager (RTM) is responsible for selecting the best route when multiple routing protocols provide a route for the same destination prefix. It makes the decision on which route to add to the routing table based on the administrative distance, metric, and other criteria.

NEW QUESTION # 26
Refer to the exhibit.

Examine the physical topology of the IS-IS network, the metrics of the links and the levels of the routers. All routers have their system interfaces included in IS-IS. Which of the following statements describes the route-table entry that router R4 will use to reach the system IP address of router R6?

A. Router R4 will have a default route with router R2 as the next-hop.
B. Router R4 will have a default route with router R3 as the next-hop.
C. Router R4 will have a route to router R6's system IP address with router R2 as the next-hop.
D. Router R4 will not have a matching entry in its routing table for router R6's system IP address.

Answer: C

Explanation:
Router R4 is in Area 49.0001 and R6 is in Area 49.0002. Both routers are Level 2 (L2), meaning that they can communicate across areas using Level 2 IS-IS routing.
Since R2 is the L1/L2 router that connects both Area 49.0001 and Area 49.0002, it will be the next-hop for router R4 to reach R6's system IP address.
The IS-IS protocol will ensure that R4 will have a route to R6's system IP address via R2 as the next-hop.

NEW QUESTION # 27
Which of the following is NOT a required configuration step to successfully run IS-IS on a router?

A. Layer-3 interfaces that will participate in IS-IS need to be identified.
B. A reference bandwidth needs to be configured to calculate link costs.
C. The IS-IS context needs to be enabled.
D. The router needs to be associated with an IS-IS area ID.

Answer: B

Explanation:
While configuring a reference bandwidth (which is used to calculate link costs) can be useful, it is not strictly required for IS-IS to run. IS-IS uses default bandwidth values to calculate costs, and it can function without explicitly configuring a reference bandwidth.
