Huawei H12-831_V1.0 Exam - Topic 1 Question 83 Discussion

Actual exam question for Huawei's H12-831_V1.0 exam

Question #: 83
Topic #: 1

On the network shown in the figure, the DHCP server function is enabled on GE0/0/0 of R2, and the address pool is an interface address pool.

When GE0/0/0 and GE0/0/1 of R1 function as DHCP clients, only one interface can obtain an IP address by default.

Options:

ATRUE

BFALSE

Show Suggested Answer

Suggested Answer: A

Comprehensive and Detailed In-Depth

Understanding the DHCP Process in This Scenario:

DHCP Server on R2:

The DHCP server is configured on interface GE0/0/0 of R2.

The address pool is an interface address pool, meaning that IP addresses are allocated from the subnet of GE0/0/0 (i.e., 10.0.12.0/24).

DHCP Clients on R1:

Both interfaces (GE0/0/0 and GE0/0/1) on R1 are set as DHCP clients, meaning they will send DHCP DISCOVER messages to obtain an IP address dynamically.

Why Only One Interface Gets an IP Address?

Interface address pools in Huawei devices assign only one IP address per MAC address (which is typically the router's MAC).

Since both interfaces belong to R1, they share the same MAC address when making a DHCP request.

As a result, the DHCP server on R2 only assigns one IP address to the first requesting interface.

The second request is ignored or denied by the DHCP server due to the duplicate MAC address issue.

Key Takeaways:

Huawei routers using an interface-based DHCP address pool assign only one IP per MAC address.

Since both interfaces on R1 have the same MAC, only one gets an IP.

This behavior is expected in Huawei's HCIP-Datacom-certified DHCP configurations.

Still, only one gets it by default.

I believe it's TRUE since the interface address pool usually limits the number of clients that can get an IP address. I remember discussing this in class.

This seems similar to a practice question we did on DHCP configurations. I feel like it might be FALSE, but I need to double-check the details.

I'm not so sure about that. I remember something about DHCP relay and how multiple clients can sometimes get addresses, but I can't recall the specifics.

I think the statement is TRUE because typically, a DHCP server assigns IP addresses based on the available pool, and only one client can get an address from the interface pool.
