Nokia IS-IS Routing Protocol Sample Questions (Q35-Q40):

NEW QUESTION # 35
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?

A. The local router ID and the router IDs of neighboring routers.
B. The IP prefixes of subnets directly attached to the router.
C. A copy of the local routing table.
D. IP prefixes known by the router because it is running ad additional routing protocol.

Answer: C

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 # 36
Two IS-IS routers are exchanging Hello packets. One is configured to use authentication and the other is not. Which of the following statements is TRUE?

A. The two routers will negotiate the authentication parameters and the establish an adjacency.
B. An adjacency will not be established.
C. An adjacency will be established without authentication.
D. An adjacency will be established with authentication using the default parameters defined for IS-IS routers.

Answer: B

Explanation:
IS-IS routers must have matching authentication settings to establish an adjacency. If one router is configured with authentication and the other is not, the routers will not be able to establish an adjacency because their authentication parameters do not match.

NEW QUESTION # 37
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. They can be assigned IPv4 and/or IPv6 addresses.
D. The system interface exists by default.

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.

NEW QUESTION # 38
There are several differences between IS-IS Hello packets used on broadcast interfaces and on point-to-point interfaces.
Which of the following statements is FALSE?

A. On broadcast interfaces there are different Hello packet types for level-1 and level-2 adjacencies, whereas on point-to-point interfaces there is a single Hello packet type.
B. The multicast MAC addresses to which the Hello messages are sent are different on broadcast interfaces and on point-to-point interfaces.
C. The neighbors are identified using their interface MAC addresses on broadcast Hello messages and using their system IDs on point-to-point Hello messages.
D. Broadcast Hello messages identify the elected designed IS (DIS) and point-to-point Hello messages do not.

Answer: C

Explanation:
In both broadcast and point-to-point interfaces, IS-IS routers identify neighbors using system IDs, not interface MAC addresses. The system ID is a unique identifier assigned to each router, and it is used to identify neighbors in both types of interfaces.

NEW QUESTION # 39
Which of the following is a valid alternative representation of the IPv6 address
2001:0da8:0000:0000:0024:0000:4ab9:0300?

A. 2001:da8::24:0:4ab9:300
B. 2001:da8::0:24::4ab9:300
C. 2001:0da8::0024:0000:4ab9:03
D. 2001:da8::24::4ab9:300

Answer: C

Explanation:
In IPv6, consecutive sections of zeros can be abbreviated with a double colon (::) once in an address. Also, leading zeros in each hextet (group of four hexadecimal digits) can be removed.
The original address is 2001:0da8:0000:0000:0024:0000:4ab9:0300.
Removing leading zeros and applying the abbreviation:
