Nokia OSPF Routing Protocol Exam Sample Questions (Q75-Q80):

NEW QUESTION # 75
An OSPF ASBR must have at least one interface in the backbone area (area 0)

A. True
B. False

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
From Nokia 7750 SR OS Routing Protocols Guide (OSPF ASBR Behavior):
An ASBR can exist in any OSPF area - including stub or NSSA areas.
There is no requirement that an ASBR be directly connected to area 0.
Thus, correct answer: B (False).

NEW QUESTION # 76
Which of the following OSPF area types are supported by the Alcatel-Lucent 7750 SR? Choose two answers.

A. Level1 area WC
B. Stub areas
C. Not so stubby areas
D. Level 2 areas
E. Partially stubby areas

Answer: B,C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
FromNokia 7750 SR OS OSPF Guide - Area Types Section:
"The 7750 SR supports standard areas, stub areas, and not-so-stubby areas (NSSA)." NSSA (Not-So-Stubby Areas) are supported.
Stub Areas are supported.
Terms like Level 1, Level 2, or WC do not apply to OSPF but rather to IS-IS.
Thus, the correct answers are A and C.

NEW QUESTION # 77
An operator configures a Nokia 7750 SR with a loopback interface and IPv6 address. The operator then configures a routing policy to redistribute the loopback prefix into OSPFv3. What type of LSA is used to advertise the route to other OSPFv3 routers in the same area?

A. Network LSA
B. Router LSA
C. Intra-Area Prefix LSA
D. None of the statements are correct.
E. Inter-Area Prefix LSA
F. AS External LSA

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
From Nokia 7750 SR OS Routing Protocols Guide (OSPFv3 Prefix Advertisement):
In OSPFv3, loopback interface prefixes are advertised using Intra-Area Prefix LSAs (Type 9).
Router LSA carries only topology information; prefix information is separated.
Thus, correct answer: C.
-

NEW QUESTION # 78
What causes an adjacency to change from down to two ways?

A. When a router receives a Hello packet that contains its own router ID in the neighbor list from a neighbor.
B. When a link state update is received in response to a link state request.
C. When a router receives a database description packet from a neighbor.
D. When a link state acknowledgement is received in response to a link state update.

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
FromNokia 7750 SR OS OSPF Guide - OSPF Neighbor State Machine:
"The transition from Down to 2-Way occurs when a Hello packet is received that includes the router's own Router ID in the neighbor list. This confirms bidirectional communication." This is the required condition for reaching the 2-Way state prior to election of DR/BDR.

NEW QUESTION # 79
Which type of OSPF LSA has the following characteristics: It is flooded only within the area it originates from and can be originated by any OSPF router within the area (including non-DR routers).

A. Type 1 Router LSA
B. Type 4 ASBR LSA
C. Type 2 Network LSA
D. Type 3 Summary LSA

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract (Nokia 7750 SR OS Routing Protocols Guide
- OSPF LSA Types Summary):
Type 1 Router LSAs are originated by every OSPF router, flooded within their own area.
They describe the router's links, neighbors, and local topology.
Type 2 LSAs are generated only by the DR.
Thus, correct answer: A.
-
