Free Huawei H12-831_V1.0-ENU Exam Dumps Questions & Answers

On the OSPFv3 network shown in the figure:
* Area 1 is a stub area, Area 2 is a common area, and Area 3 is an NSSA (Not-So-Stubby Area).
* The IPv6 address of Loopback0 on R6 is 2000::6/128.
* The router ID of each router is 10.0.X.X, where X is the router number.
* The stub no-summary command is configured in Area 1 on R2.
Which of the following statements is true?

• A.  The routing table of R4 does not contain the route 2000::6/128.
• B.  The path for data packets from R4 to 2000::6 is R4 - > R1 - > R5 - > R3 - > R6.
• C.  The path for data packets from R4 to 2000::6 is R4 - > R2 - > R6.
• D.  The LSDB of R4 contains the Inter-Area-Prefix-LSA that is generated by R1 and describes 2000::6/128.

On the OSPFv3 network shown in the figure, area 1 is an NSSA. R1 imports the external route 2000::1/128 to OSPFv3. Which of the following LSAs does not exist in area 1?

• A.  NSSA LSA
• B.  AS-External-LSA
• C.  Inter-Area-Prefix-LSA
• D.  Intra-Area-Prefix-LSA

On the OSPF network shown in the figure, area 1 is a totally NSSA, area 2 is a common area, and R4 imports an external route 10.0.4.4/32. The router ID of each router is 10.0.X.X, where X is the number of the router.
The asbr-summary 10.0.4.0 255.255.255.0 command is configured in the OSPF processes of R1 and R3.
Which of the following statements is true?

• A.  Area 0 does not have Type 5 LSAs.
• B.  Area 2 does not have Type 7 LSAs.
• C.  Area 0 does not have Type 4 LSAs.
• D.  Area 1 does not have Type 7 LSAs.

On the OSPF network shown in the figure, R1 and R2 use OSPF to communicate with each other through Loopback0. In addition:
* MPLS LDP is enabled on R1 and R2.
* The LDP transport address is the IP address of Loopback0.
* A network engineer finds that an LDP session cannot be established between R1 and R2 and runs diagnostic commands (shown in the figure) to locate the fault.
Given this, which of the following are possible causes of the fault?

Options:

• A.  MPLS LDP is not enabled on R2's GE0/0/1.
• B.  R2's GE0/0/1 rejects packets with TCP destination port 646.
• C.  R1's GE0/0/1 rejects packets with UDP destination port 646.
• D.  R1's GE0/0/1 rejects packets with the destination IP address 10.0.2.2.

On the 05PFv3 network shown in the figure, each interface of R1 and R2 has two IPv6 addresses. Although the IPv6 address prefixes of R1 and R2 are different, they can still be used to establish an OSPFv3 neighbor relationship. If R2 is the DR, the Intra-Area-Prefix-LSA generated by R2 contains four prefixes.

• A.  FALSE
• B.  TRUE
