Huawei HCIE-Routing & Switching (Written) V3.0 Sample Questions:
Which of the following descriptions is correct about the MPLS processing mode for TTL?
- A. in Pipe mode. When an IP packet passes through an MPLS network, at the ingress node, IP TTL minus
1 maps to MPLS TTL field. - B. in the MPLS labelTTL, which has the same meaning as the TL field in the IP header. TTL can prevent routing loops in MPLS networks.
- C. In Unifor mode, when IP packets pass through the MPLS network, the TTL minus 1. MPLS The TTL field is a fixed value.
- D. in MPLS In VPI, if you want to hide the structure of the MPLS backbone network, you can use the IngUni on ress form mode.

In the campus network, what are the problems of manually creating static tunnels?
- A. Static tunnels also use related protocols on the control plane, which will cause equipment resource loss
- B. Although the static VXLAN tunnel mode can support distributed gateway application scenarios, the configuration workload is large and the configuration adjustment is complicated
- C. If N devices establish static VXLAN tunnels, at most N(N-1)/2 tunnels need to be manually configured, and the amount of configuration is large.
- D. VTEP can only rely on data flooding to learn the remote MAC address
Correct Answer: C,D 🗳️
As shown in the figure, there is a PPP link between R1 and R2, and the direct-connected interfaces are not in the same network segment, but the direct-connected interfaces of R1 and R2 can communicate, but the Ethernet link cannot communicate with the same IP plan. The reason is that? (multiple choice)
- A. The interconnected POS ports of R1 and R2 learn the MAC address of the peer interface through LCP, and do not need to use ARP to request the MAC address
- B. The data packets of the interconnected POS ports of R1 and R2 do not need to encapsulate the Ethernet header, and do not need to use ARP to request the MAC address
- C. The interconnected POS ports of R1 and R2 learn the 24-bit subnet route of each other's directly connected ports through IPCP
- D. The interconnected POS ports of R1 and R2 learn the 32-bit host route of each other's directly connected ports through IPCP
Correct Answer: B,D 🗳️
