Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q24-Q29):

NEW QUESTION # 24
As shown in the figure, data traffic is forwarded in tunnel mode along the path of STA -> HAP -> HAC -> upper-layer network before roaming. What is the flow direction of data traffic after Layer 3 roaming?

  • A. STA -> FAP -> FAC -> Upper-layer network
  • B. STA -> FAP -> FAC -> HAC -> HAP -> Upper-layer network
  • C. STA -> FAP -> FAC -> HAC -> Upper-layer network
  • D. STA -> FAP -> FAC -> HAC -> HAP -> HAC -> Upper-layer network

Answer: C

Explanation:
After Layer 3 roaming, the STA's traffic is forwarded from the Foreign AP (FAP) to the Foreign AC (FAC), and then to the Home AC (HAC) before reaching the upper-layer network. This ensures that the STA remains on the same subnet without breaking existing sessions .


NEW QUESTION # 25
What parameters can a DHCP6 server assign to a DHCPv6 client?

  • A. SNTP server address
  • B. DNS server address
  • C. Gateway address
  • D. IPV6 address/prefix

Answer: A


NEW QUESTION # 26
After the administrator of an enterprise deploys a DHCP server, employees complain that their clients cannot obtain IP addresses from the DHCP server. Which of the following may cause this problem?

  • A. The DHCP function is disabled by default, and the administrator forgets to enable the DHCP function.
  • B. STP is enabled on the DHCP server.
  • C. DHCP clients and the DHCP server are on different network segments, and no DHCP relay agent is configured on the network.
  • D. Multiple DHCP servers are configured.

Answer: A,C

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* DHCP Configuration Issues:
* Option C: The DHCP function is disabled by default on Huawei devices. If the administrator forgets to enable it, clients cannot receive IP addresses.
* Option D: DHCP uses broadcast messages, which do not traverse routers. If the clients and DHCP server are on different subnets, a DHCP relay agent must be configured.
* Other Options:
* Option A: Multiple DHCP servers can coexist as long as their IP address pools do not overlap.
This is unlikely to cause the problem.
* Option B: STP does not affect DHCP operations unless it delays port activation, which is uncommon in this scenario.
