Huawei Exam H12-891_V1.0 Topic 4 Question 56 Discussion

Actual exam question for Huawei's H12-891_V1.0 exam

Question #: 56
Topic #: 4

As shown in the figure, the PPP link between R1 and R2 is not in the same network segment, but the R1 and R2 direct connectors can communicate, and the Ethernet link cannot communicate under the same planning, why?

AThe interconnect POS ports of R1 and R2 learn the 24-bit subnet route of each other's direct connection ports through IPCP

BThe interconnect POS ports of R1 and R2 learn the 32-bit host route for each other's direct connections through IPCP

CThe interconnect POS port of RI and R2, through LCP learns the MAC address of the opposite termination , does not need to use ARP to request the MAC address

DThe data packets of the interconnect POS ports of R1 and R2 do not need to encapsulate ethernet headers and do not need to use ARP to request MAC addresses

Option D makes the most sense to me. No need for Ethernet when the routers can talk directly over the PPP link. Gotta love those networking shortcuts!

D is the way to go. PPP links can communicate directly without the overhead of Ethernet headers and ARP. Saves a lot of time and resources.

Haha, the question is so confusing, I feel like I need a Ph.D. in networking to understand it. But I'll go with D, it sounds the most logical.

I think the answer is C. The LCP protocol allows the interconnect ports to learn the MAC addresses of the other end, so no ARP is needed.

The correct answer is D. The PPP links between R1 and R2 do not need to use Ethernet headers or ARP since they communicate directly at the network layer.

Interesting point, Reuben. But I still think option A makes more sense in this scenario.
