Wired and wireless convergence is one of the trends of campus network development. Switches with WAC cards can implement Wired and Wireless Network Convergence at both hardware andsoftware levels.
Correct Answer:A
Wired and wireless convergence is a key trend in modern campus networks, enabling unified management and seamless connectivity across wired and wireless devices. Huawei switches equippedwithWireless Access Controller (WAC) cardsintegrate wired and wireless functions into a single platform. This integration provides:
Hardware-level convergence:Combines switching and wireless control capabilities in one device.
Software-level convergence:Enables centralized management, policy enforcement, and traffic optimization for both wired and wireless networks.
This approach simplifies network architecture, reduces costs, and improves operational efficiency, making it a preferred solution for converged campus networks.

In the latest-generation WPA3 encryption standard, the key length is 192 bits, making WPA3 more secure than WPA2.
Correct Answer:A
Comprehensive and Detailed in Depth Explanation:WPA3 (Wi-Fi Protected Access 3) introduces enhanced security features compared to WPA2. One of the key improvements is the use of a 192-bit encryption key in the WPA3 Enterprise mode, which provides stronger cryptographic protection. This is part of the "WPA3-Enterprise 192-bit" mode, designed for high-security environments such as government and financial institutions. The increased key length enhances resistance to brute-force attacks and ensures better protection of sensitive data. Additionally, WPA3 includes features like Simultaneous Authentication of Equals (SAE), which replaces the Pre-Shared Key (PSK) mechanism, further improving security.

In order to increase the redundancy of leaf switches, we can use stack or M-LAG technology. However, Huawei CloudEngine 6881 cannot support M-LAG.
Correct Answer:B
The Huawei CloudEngine 6881 is a high-performance data center switch that supports both stacking and M-LAG (Multichassis Link Aggregation Group) technologies. M-LAG is a key feature for increasing redundancy and reliability in leaf-spine architectures by enabling two switches to act as a single logical device for link aggregation.
The claim that the CE6881 does not support M-LAG is FALSE , as this model fully supports M-LAG to enhance network availability and fault tolerance.

Which of the following are factors affecting the wireless rate (throughput) of a Wi-Fi AP? (Select All that Apply)
Correct Answer:ABCD
Factors Affecting Wireless Rate:
The wireless rate (throughput) of a Wi-Fi AP depends on multiple factors, including hardware capabilities, environmental conditions, and configuration settings. Explanation of Each Factor:
CPU performance:The AP's CPU processes data packets and performs tasks like encryption/decryption. Higher CPU performance enables better throughput.
SNR (Signal-to-Noise Ratio):A higher SNR indicates a stronger signal relative to noise, resulting in better data rates.
Spatial stream:Wi-Fi 6 supports multiple spatial streams (MIMO), increasing throughput by transmitting multiple data streams simultaneously.
Frequency bandwidth:Wider channels (e.g., 20 MHz, 40 MHz, 80 MHz, or 160 MHz) allow higher data rates but may increase interference in crowded environments.
Conclusion:All four options are factors that affect the wireless rate of a Wi-Fi AP. References:
