Nokia 4A0-112 exam is designed to test the knowledge and skills of IT professionals in implementing and managing networks using Nokia's Intermediate System-to-Intermediate System (IS-IS) routing protocol. 4A0-112 Exam is intended for those who have a strong background in networking and wish to validate their proficiency in Nokia's IS-IS routing technology.
NEW QUESTION # 21
A routing domain is using a single-area link-state routing protocol. Which of the following is NOT information that a router can share with other routers in the domain using protocol-specific messages?
Answer: B
Explanation:
In a single-area link-state routing protocol (such as OSPF), routers share specific information about the network topology, not their entire routing table. They exchange link-state advertisements (LSAs) that contain information about their directly connected interfaces and their state, allowing other routers to build a consistent view of the network.
NEW QUESTION # 22
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?
Answer: A
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 # 23
An IS-IS router receives a CSNP that references an older LSP than the one in its local database. What action is taken?
Answer: B
Explanation:
When a router receives a CSNP (Complete Sequence Number PDU) that references an older LSP (Link-State PDU) than the one in its local database, it indicates that the neighbor is missing newer information.
In response, the router sends back a PSNP (Partial Sequence Number PDU) to the neighbor, which includes a copy of the LSPs it has in its local database that the neighbor may not yet have. This helps to synchronize the link-state information between routers.
NEW QUESTION # 24
Two IS-IS neighboring routers are trying to establish an adjacency, but the interface has been configured as broadcast on one of them and as point-to-point on the other. Why is the adjacency not established?
Answer: C
Explanation:
IS-IS routers use different types of Hello messages depending on whether the interface is configured as a broadcast (LAN) or point-to-point (P2P) link.
On a broadcast network (e.g., Ethernet), IS-IS routers use LAN Hello packets to establish adjacencies.
On a point-to-point link, IS-IS uses point-to-point Hello packets.
If one router is configured for a broadcast interface and the other for point-to-point, they will exchange incompatible Hello packets, and as a result, neither router will accept the other's Hello messages, preventing the adjacency from being established.
NEW QUESTION # 25
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?
Answer: C
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.
