Huawei H12-891_V1.0 Exam - Topic 1 Question 6 Discussion

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

Question #: 6
Topic #: 1

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

No way, I thought Ethernet was always reliable for communication!

I think it's because of the encapsulation differences.

Wait, so the Ethernet link can't communicate? That seems odd.

R1 and R2 can communicate directly via IPCP.

I practiced a similar question where the focus was on how MAC addresses are handled in different protocols. I think option D might be the right answer since it mentions not needing ARP.

I’m a bit confused about the IPCP and LCP terms. I think they have to do with how the routers establish communication, but I can't recall the specifics.

This question feels familiar; I think it relates to how PPP handles addressing differently compared to Ethernet. Maybe it has to do with the encapsulation process?

I remember something about how PPP can work across different network segments, but I'm not entirely sure why the Ethernet link fails in this case.

Alright, time to put on my troubleshooting hat. I'll need to carefully analyze the exhibit and the possible explanations to determine the correct statement. Methodical approach is key here.

Hmm, I'm a bit unsure about this one. I know we're dealing with a partition table, but I'm not totally clear on the differences between the options. I'll need to think this through carefully.

I remember studying that the border leaf plays a key role in connecting different sites, but I'm a bit unsure if it's specifically the main component in VXLAN EVPN architecture.

Hmm, this seems like a tricky one. I'll need to think through the responsibilities of a steering committee or improvement council carefully.

I think Option B is the way to go. Designing flexible tests that can be updated is key when requirements are still in flux. We've handled this before on similar projects.

Hmm, I'm a bit unsure about this one. I'll need to carefully review the options and think through what's most important for a cloud-based disaster recovery plan.
