Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 認定 H12-831_V1.0-ENU 試験問題:
1. In CE multi-homing scenarios, if BGP AS number substitution is enabled on PEs, you can run the peer soo command on the EBGP peers of the PEs and CE to configure the Site of Origin (SoO) attribute to prevent loops.
A) TRUE
B) FALSE
2. When an OSPFv3 message is encapsulated in an IPv6 message, which of the following is the value of the Next Header field in the IPv6 message header?
A) 189
B) 89
C) 17
D) 6
3. In the CE multi-homing scenario, if the PE enables the BGP AS number replacement function, you can also configure the Soo feature to avoid loops, that is, enable this feature through the peer soo command on the EBGP peers between PE and CE.
A) True
B) False
4. As shown in the figure, RIR4 is one of the four routers in AS 123. They all run OSPE and realize the routing interconnection within the AS. Among them, the two network segments 10.1.1.0/24 and 10.4.4.0/24 are not published to OSPF. Now, R1 and R4 have established an IBGP peer relationship based on the Loopback0 interface, and published the network segments 10.1.1.0/24 and 10.4.4.0/24 to BGP respectively.
Which of the following methods can enable PC1 and PC2 to communicate with each other?
(Multiple choice)
A) On R1 and R4, import routes 10.1.1.0/24 and 10.4.4.0/24 into OSPF respectively.
B) Activate MPLS and LDP on R1~R4 and establish LSPs for routes 1.1.1.1/32 and 4.4.4.4/32.
C) Run BGP on R2 and R3 and establish IBGP full interconnection in AS123
D) Deploy policy routing on R1 and specify R2 as the next hop for traffic from PC1 to PC2.
5. In the network shown in the figure, R1 and R2 are configured with single-hop BFD detection. The network engineer found that the BFD session was Down, so he queried the BFD-related configurations of R1 and R2. The configuration information has been marked in the figure.
In addition, the network engineer performed the Ping 10.0.12.2 operation on R1, and the output information is shown in the figure.
Based on this, the possible reason for the BFD session going Down is that the packets with UDP port 4784 are rejected.
A) True
B) False
