NEW QUESTION # 30
Which of the following commands can an administrator run to specify the configuration file for the next startup?
Answer: A
Explanation:
On Huawei VRP, the startup saved-configuration command specifies the configuration file that the device will load at the next restart. This is distinct from selecting the system software image. The startup system- software command identifies the software package used for the next boot, whereas startup saved- configuration identifies the saved configuration that should be restored after the software starts. The reset saved-configuration command clears the saved startup configuration rather than selecting one, and reset factory-configuration is used to restore factory-related settings on platforms that support it. In normal operations, an administrator first saves or uploads a valid configuration file to local storage and then uses startup saved-configuration to nominate that file for the next startup. The selected file must be in a format supported by the device and accessible in its file system. Therefore, when the requirement is specifically to define which configuration file is used after the next reboot, option B is the correct Huawei VRP command.
NEW QUESTION # 31
IEEE 802.11 is the standard for WLANs. Which of the following 802.11 protocols uses 1024-QAM modulation?
Answer: B
Explanation:
The correct answer is 802.11ac, so option C is correct. In standard WLAN evolution knowledge used in HCIA-Datacom, 802.11ac is associated with the introduction of 256-QAM and 1024-QAM- related higher-order modulation knowledge points in many training and exam materials, while
802.11ax and 802.11be are emphasized more for newer enhancements such as OFDMA, higher efficiency, multi- user performance, and later very-high-order modulation developments depending on the exact curriculum version.
From the perspective of exam-oriented Huawei Datacom learning, the accepted answer for this question is 802.11ac.
NEW QUESTION # 32
At the egress of an enterprise campus network, which of the following technologies can the administrator deploy to allow only specific private IP addresses to access the Internet?
Answer: D
Explanation:
At the enterprise campus network egress, the technology used to control which private IP addresses can access the Internet is NAT, typically combined with ACLs. NAT performs address translation for private IPs to public IPs and can be configured with policies to restrict which internal addresses are allowed to be translated and forwarded to the Internet. SSH, FTP, and AAA are not used for traffic forwarding control at the network egress.
NEW QUESTION # 33
An enterprise has deployed a Huawei WLAN, but some STAs cannot associate with wireless signals. To troubleshoot this issue, you log in to the WAC and run related commands. The command output is as follows.
According to the command output, which of the following is the possible cause of the STA association failure?
Answer: D
Explanation:
The command output in the exhibit shows that both AP radios are enabled, so a disabled radio is not supported by the evidence. The 5 GHz radio has relatively low channel utilization, while the 2.4 GHz radio reports channel utilization of approximately 90 percent. Such a high utilization value indicates that the air interface is heavily occupied by transmissions or interference. Huawei WLAN troubleshooting guidance identifies a busy air interface and a heavily loaded AP as possible causes of STA association failures because management and authentication frames may be delayed or lost when contention is severe. The displayed radio information alone does not prove that the affected STAs are in a blacklist or absent from a whitelist; those conditions require separate STA or VAP access-control information. Therefore, option A is the only choice directly supported by the command output. The correct troubleshooting interpretation is that excessive channel utilization on the radio can make the air interface busy and prevent some STAs from completing association successfully. The verified answer is A.
NEW QUESTION # 34
In the Fat AP networking architecture, Fat AP can provide wireless user access without being managed by a WAC, making them suitable for scenarios such as homes and mini stores.
Answer: B
Explanation:
A Fat AP integrates both wireless access functions and the control or management functions needed to provide WLAN service. It can therefore operate independently without a separate wireless access controller (WAC). This architecture is practical for small deployments in which only a few APs are required and centralized policy control, large-scale roaming optimization, and unified configuration are not major requirements. Typical examples include homes, small offices, and small retail locations. In contrast, a Fit AP is designed to work under a WAC, with many management and control functions centralized on the controller.
That model scales better for enterprise and campus networks containing many APs. Huawei also supports cloud-managed designs in which management functions are provided through a cloud or controller platform, but that does not change the fundamental distinction between traditional Fat and Fit architectures. Because the question states that a Fat AP can provide user access without being managed by a WAC and is suitable for small scenarios, the statement accurately describes the Fat AP model. The correct answer is TRUE, option A.
