PQ (Priority Queuing) ensures low-latency services like voice and video are prioritized.

WFQ (Weighted Fair Queuing) fairly allocates remaining bandwidth to services like FTP.

Option B provides a balanced approach: guarantees for voice/video via PQ, and fairness for FTP via WFQ.

Exact Extract - Huawei HCIE-Datacom QoS Module:

“Voice and video traffic should be handled by PQ to minimize delay and jitter. Non-critical services such as FTP should be placed in WFQ queues to ensure bandwidth fairness.”

Huawei’s Network Access Control (NAC) Portal authentication supports various identity authentication methods for user login via a web page. These include:

Username and password — standard method.

Passcode — one-time password or PIN.

SMS verification code — users receive a dynamic code via SMS for identity verification.

However:

MAC address authentication is used in MAC-based authentication, not Portal. MAC authentication allows a device to be authenticated using its MAC address without user interaction (i.e., not via a Portal page).

Correct answer: D. User’s MAC address

Comprehensive and Detailed In-Depth Explanation:

In the Huawei iMaster NCE-Campus solution, when using a third-party Portal authentication application, the following process occurs:

After the Wi-Fi user connects to the network, any attempt to access a website for the first time triggers HTTP redirection.

The user is redirected to the login page provided by the third-party authentication application.

This mechanism ensures that the user authenticates before accessing external resources.

The redirection behavior is consistent with captive portal functionality, which is standard for user authentication on Wi-Fi networks.

Therefore, the statement is TRUE.
