Huawei HCIA-Datacom V2.0 H12-811_V2.0 Prüfungsfragen mit Lösungen (Q35-Q40):

35. Frage
In the leader AP networking architecture, the leader AP functions as a WAC and uses the CAPWAP protocol to uniformly manage and configure Fit APs.

Antwort: A

Begründung:
This statement is true . In the leader AP networking architecture, one AP acts as the leader AP , taking on controller-like functions similar to those of a WAC for a small or medium-sized WLAN deployment. It can centrally manage other Fit APs and deliver unified wireless configurations such as SSIDs, security settings, and radio parameters. CAPWAP is used for management and control communication between the leader AP and the managed Fit APs.
This architecture is useful in scenarios where deploying a dedicated WAC is unnecessary or uneconomical, but centralized AP management is still desired. It provides a balance between simplicity and control and is commonly used in branch offices, small campuses, and similar environments. HCIA-Datacom explains leader AP networking as an intermediate solution between fully autonomous AP deployment and full WAC + Fit AP enterprise architecture. The key point is that the leader AP behaves as the management node for the other APs and enables unified configuration and control. Therefore, the statement correctly describes both the role of the leader AP and the use of CAPWAP in this architecture.


36. Frage
Which of the following hosts are reachable to the host at 192.168.1.200/27 at Layer 2? (Select all that apply)

Antwort: A,B,D

Begründung:
A /27 subnet mask is 255.255.255.224, which means each subnet contains 32 IP addresses. The subnet increments in blocks of 32 in the last octet: 0, 32, 64, 96, 128, 160, 192, 224. The address 192.168.1.200/27 belongs to the subnet 192.168.1.192/27.
For this subnet, the network address is 192.168.1.192, the broadcast address is 192.168.1.223, and the valid host range is from 192.168.1.193 to 192.168.1.222. Therefore, 192.168.1.221/27, 192.168.1.193/27, and
192.168.1.222/27 are all valid host addresses in the same subnet and are reachable at Layer 2 without routing.
That makes A, C, and D correct.
Option B is not correct because 192.168.1.192/27 is the network address of the subnet and cannot be assigned to a host by default. This question checks IP subnetting and the ability to identify valid hosts within the same broadcast domain.


37. Frage
The emergence of AI poses new requirements on data center networks. To meet AI computing requirements, a high-speed intelligent computing data center network with zero packet loss needs to be constructed. Which of the following statements are false about the requirements and solutions of intelligent computing data center networks? (Select all that apply)

Antwort: C,D

Begründung:
The false statements are A and D . Option A is considered false in HCIA-Datacom wording because intelligent computing data center networks aim to build a lossless Ethernet fabric through coordinated technologies such as high-bandwidth interfaces, deep buffers, PFC, ECN, congestion control, and optimized forwarding. The exam-oriented knowledge point treats these technologies as solutions for a zero packet loss network design goal rather than stating that a truly lossless network cannot be achieved.
Option D is also false because RDMA is used to reduce end-to-end communication latency and CPU overhead between servers, especially for east-west traffic in AI and high-performance computing clusters. It is not specifically described as reducing latency between GPU servers and physical switches . That wording is inaccurate. Option B is true because PFC and ECN are standard lossless Ethernet technologies applied in intelligent computing networks. Option C is also true because AI training and distributed computing generate massive data synchronization traffic, requiring very high single-port bandwidth such as 200GE or 400GE .
HCIA-Datacom highlights bandwidth, low latency, and lossless transport as the core requirements of intelligent computing data center networks.


38. Frage
In the WAC + Fit AP networking, an AP fails to go online. The output of the display ap all command run on the WAC is shown below. According to the command output, which of the following is the possible cause of the AP's failure to go online?

Antwort: B

Begründung:
The correct answer is C. In the command output, the AP state is shown as ver-mismatch. This state directly indicates a version mismatch between the AP and the WAC. In Huawei WLAN deployment, a Fit AP must use a software version that is compatible with the WAC version. If the versions do not match, the AP may be discovered by the WAC and appear in the AP list, but it cannot successfully complete the online process.
Option A is incorrect because blacklist-related failures are displayed with blacklist-related status information, not ver-mismatch. Option B is also incorrect because authentication failures normally generate authentication- related fault indications. Option D is incorrect because configuration initialization failure would not be identified by the specific ver-mismatch state.
HCIA-Datacom troubleshooting knowledge emphasizes reading AP online states carefully. Common causes of AP online failure include IP address acquisition failure, CAPWAP tunnel establishment failure, insufficient licenses, authentication problems, and version mismatch. When the state explicitly shows ver-mismatch, the troubleshooting direction is clear: check AP and WAC software compatibility and upgrade or align the software version as needed.


39. Frage
The domain to which a user belongs is determined by the user name used by the user to log in to the NAS device. If the domain name carried in the user name is not configured on the NAS device, the authentication fails.

Antwort: A

Begründung:
This statement is false . On Huawei devices, the domain to which a user belongs is usually determined by the domain part carried in the user name, for example [email protected]. However, if the specified domain is not configured on the NAS device, authentication does not necessarily fail immediately . In many cases, the device can use a default domain for authentication processing, depending on the AAA configuration.
Huawei AAA supports both an administrator user default domain and a normal user default domain . If a user name does not match a configured domain, or the domain carried in the user name is unavailable, the device may fall back to the default domain and continue authentication according to the configured policy.
Therefore, the statement is incorrect because it treats authentication failure as unavoidable in every such case.
HCIA-Datacom emphasizes domain-based AAA processing because it allows different groups of users to use different authentication, authorization, and accounting methods. At the same time, learners must understand the function of default domains, which provide flexibility in real deployments and prevent unnecessary authentication failures in some login scenarios.
