Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 Sample Questions:
On the OSPF network shown in the figure:
* Area 1 is a common area .
* Area 2 is a totally NSSA (Not-So-Stubby Area) .
* Area 3 is an NSSA .
* R5 imports the external route 10.0.5.5/32 into OSPF .
Which of the following routers have the route 10.0.5.5/32 in their routing tables?
- A. R6
- B. R2
- C. R4
- D. R3
Correct Answer: A,B,D 🗳️
Explanation: Only visible for RealValidExam members. You can sign-up / login (it's free).
On a stable network that requires fast route convergence, you can change the value of the interval at which OSPF LSAs are updated to 0 so that topology or route changes can be immediately advertised on the network through LSAs, which speeds up route convergence.
- A. TRUE
- B. FALSE
Correct Answer: A 🗳️
BFD for OSPF refers to the association of BFD with OSPF to speed up OSPF ' s response to network topology changes. The OSPF neighbor relationship can enter the Full state only after the BFD session goes up. The OSPF neighbor relationship can go down only after the BFD session goes down.
- A. TRUE
- B. FALSE
Correct Answer: A 🗳️
On the OSPFv3 network shown in the figure, the LSDB of R2 contains ____ Router-LSAs . ( Enter only digits. )
Correct Answer:
3
Explanation:
To determine the correct answer, we need to analyze how OSPFv3 handles Router LSAs (Type 1 LSAs) in a simple Area 0 topology like the one shown in the figure.
1. Understanding OSPFv3 Router LSAs (Type 1 LSAs)
* Router LSAs (Type 1 LSAs) are generated by each router within an OSPF area to describe its own directly connected links.
* Each router in an OSPF area generates exactly one Type 1 LSA.
* The Link-State Database (LSDB) on a router contains LSAs from all routers in the same area .
2. Analyzing the Network in the Figure
* There are 3 routers: R1, R2, and R3.
* All routers are in OSPFv3 Area 0 (which is a single area).
* Each of these routers generates one Router LSA (Type 1 LSA) .
* Since R2 is in the same area as R1 and R3, its LSDB contains the Router LSAs from itself, R1, and R3 .
3. Conclusion
* The LSDB of R2 contains 3 Router LSAs (one from each router: R1, R2, and R3).
* Final answer: 3
In the hub-spoke networking shown in the figure, the Hub-PE can be configured to allow repetitive local AS numbers for correct route transmission.
- A. TRUE
- B. FALSE
Correct Answer: A 🗳️
