164. Frage
An engineer is configuring Fit AP onboarding on a Huawei WAC. After the engineer completes network connectivity and CAPWAP configuration, the next step is to configure the AP authentication mode. Which AP authentication modes can the engineer choose to configure?
(Choose all that apply.)
Antwort: A,C,D
Begründung:
Huawei WAC supports multiple AP authentication modes during Fit AP onboarding, including MAC-based authentication, SN-based authentication, and no-authentication mode. These methods define how the WAC verifies and allows APs to join the network. IP-based authentication is not a valid AP authentication mode in this context.
165. Frage
During WLAN deployment, a Fit AP fails to go online on the WAC. Which of the following commands can you run on the WAC to locate the fault? (Choose all that apply.)
Antwort: B,D
Begründung:
When a Fit AP fails to go online, the WAC troubleshooting focuses on AP registration and onboarding status. The command display ap all shows the AP status and helps identify whether the AP is offline or not registered. The command display ap online-fail-record all provides detailed failure reasons for APs that failed to go online, which is directly used for fault location.
Commands related to VAP and SSID profiles are used for WLAN service configuration verification and do not help in diagnosing AP onboarding failures.
166. Frage
The following ACL rule is configured on R1, but the service module has not invoked the rule:
[R1] acl number 2001
[R1-acl4-basic-2001] rule permit source 172.16.105.0 0.0.0.255
[R1-acl4-basic-2001] rule deny source any
[R1-acl4-basic-2001] quit
By default, R1 allows only hosts on 172.16.105.0/24 to access R1.
Antwort: A
Begründung:
The ACL is configured but not applied to any service module or interface. On Huawei devices, an ACL has no effect unless it is explicitly referenced (for example, in an interface, FTP service, or traffic policy). Therefore, by default, it does not restrict access to R1. The statement claiming that only 172.16.105.0/24 can access R1 is incorrect.
167. Frage
When a host uses the stateless address autoconfiguration solution to obtain an IPv6 address, the host cannot obtain the DNS server address.
Antwort: B
Begründung:
Stateless Address Autoconfiguration (SLAAC) allows IPv6 hosts to generate their own IP addresses but does not include DNS server information. DHCPv6 is typically required for DNS configuration.
168. Frage
Huawei launched the leader AP networking solution for small and micro enterprises. APs can operate independently or manage a small number of APs. Which of the following statements are true about the leader AP networking architecture? (Choose all that apply.)
Antwort: A,D
Begründung:
Leader AP networking supports basic WLAN service functions such as user access and roaming within a small-scale network, enabling seamless mobility for STAs. In this architecture, the leader AP can also provide DHCP service to assign IP addresses to wireless clients, simplifying deployment in small and micro enterprise scenarios.
The leader AP does not use CAPWAP to manage Fit APs, as this solution is designed to be lightweight and typically does not rely on a WAC-based CAPWAP control architecture.
Additionally, the leader AP does not operate in Fit mode; it functions in a hybrid/leader role combining control and service capabilities.
