Nokia IS-IS Routing Protocol Sample Questions (Q41-Q46):

NEW QUESTION # 41
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: D

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 # 42
Refer to the exhibit.

All routers in the diagram are running a link-state routing protocol. Before the link failure, all routers have operational adjacencies with each other and there is a BFD session between routers R1 and R3. After the link failure, which of the following affects the routing protocol's convergence time?

A. The value of the BFD transmit interval, receive interval and multiplier settings on routers R1 and R3.
B. The time taken by the switches to detect that the physical ports are down.
C. The value of the routing protocol hello timers on routers R1 and R3.
D. The value of the Ethernet hello timers on the switches.

Answer: A

Explanation:
BFD (Bidirectional Forwarding Detection) is used to detect link failures quickly and helps improve convergence time in link-state routing protocols. The BFD session between routers R1 and R3 allows them to detect the failure of the link between them more quickly than the regular routing protocol hello timers. The transmit interval, receive interval, and multiplier settings determine how fast BFD detects a failure and triggers the routing protocol to converge, which directly impacts the convergence time.

NEW QUESTION # 43
Refer to the exhibit.

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

A. Multi-area IS-IS domain with no broadcast interfaces.
B. Multi-area IS-IS domain with broadcast interfaces.
C. Single-area IS-IS domain with 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 # 44
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 # 45
When a router performs the SPF calculation, which router is used as the root of the shortest path tree?

A. The router with the fewest links.
B. The router doing the calculation.
C. The router's closest neighbor.
D. The router with the lowest router ID.

Answer: B

Explanation:
When a router performs the SPF (Shortest Path First) calculation, it uses itself as the root of the shortest path tree (SPT). This router computes the shortest paths to all other routers in the network, treating itself as the origin and calculating the paths based on its view of the network.
