Configuring the AC Country Code in Huawei WLAN View
Short answer
B Enter WLAN view on the AC and use the country-code command, for example country-code cn, to set the regulatory domain.
Question
Key Takeaways
This question tests memorisation of the exact VRP keyword for the WLAN regulatory domain; the trap is choosing a plausible synonym like nation-code or a sub-national term like province-code or state-code.
Huawei ACs set the wireless regulatory domain with the country-code command in WLAN view, which fixes the permitted channels and transmit power. The correct option is B, because nation-code, province-code and state-code are not valid VRP commands.
Common mistake: Option A, nation-code, is the most tempting error because it sounds synonymous with country code, but VRP has no nation-code command — the documented keyword is country-code.
Expert Analysis
The governing principle
On Huawei wireless LAN controllers, the regulatory domain is set under the AC's global WLAN view with a single documented command: country-code. The value takes an ISO country code such as cn, us, or de, and it must be configured before any radio can be activated. The country code determines which channels, channel widths and transmit power levels the radios are legally allowed to use in that jurisdiction, so VRP validates the rest of the WLAN configuration against it.
Mapping the scenario
The question asks for the command that configures the country code on an AC. The typical sequence is system-view, then wlan to enter WLAN view, then country-code cn (or the appropriate ISO code). Option B, country-code, matches this documented syntax exactly.
Why the other options fail
Option A, nation-code, is a plausible-sounding synonym but is not a VRP command — VRP uses the internationally recognised term "country" rather than "nation". Options C, province-code and D, state-code, describe sub-national administrative regions, which do not exist in the WLAN regulatory model; radio regulation is defined at national level by bodies such as the MIIT in China or the FCC in the United States, and VRP therefore has no command for them. A supporting comment in the community notes precisely this: on Huawei ACs country-code is used to configure the country code, which determines the radio regulations and channels available for wireless operation, and the other three options are simply not valid VRP commands.
Exam takeaway
This is a pure command-recognition question. Recognise that WLAN regulatory settings live in wlan view and are expressed with hyphenated English keywords; when an option mirrors everyday administrative vocabulary that VRP does not use (nation, province, state), reject it in favour of the documented keyword.
Exam Strategy
For Huawei VRP command-recognition questions, enter the relevant view in your head first — WLAN settings sit in wlan view — then match the keyword to the feature name the vendor documents. Reject options that use everyday synonyms (nation, province, state) that never appear in VRP help output; the real command almost always mirrors the English feature name exactly, as country-code does here. When stuck between two similar keywords, type the feature name into the mental command tree and pick the one Huawei would list.
