A. VDSL

B. IPS, antivirus, and URL filtering

C. PoE

D. Wi-Fi

A. Traditional QoS can manage or schedule traffic of multiple services for multiple users simultaneously.

B. Traditional QoS schedules traffic based on interface bandwidth, allowing services to be differentiated by service level. However, it is difficult to differentiate services by user. Therefore, traditional QoS is typically applied at the core layer rather than the access layer.

C. Traditional QoS technologies can provide differentiated services to meet the requirements of voice, video, and data services.

D. Hierarchical Quality of Service (HQoS) uses queue-based hierarchical scheduling to provide fine- grained quality assurance for services of different users.

A. Tunnel forwarding facilitates centralized management and control of wireless traffic.

B. Direct forwarding is more efficient.

C. Tunnel forwarding has the disadvantage of traffic detour, which increases the forwarding-performance pressure on the WAC.

D. Direct forwarding is not suitable for scenarios that have high requirements for roaming performance.
This is because roaming performance deteriorates slightly when a STA roams across edge nodes.

A. Traffic statistics: Traffic statistics are collected based on different terminal types, and reports are generated.

B. Authentication and authorization: Different network access permissions are assigned to different types of terminals.

C. Spoofing detection: Terminal type changes are checked to provide a basis for spoofing detection.

D. Wired authentication: Terminals are identified through wired authentication.

A. ESP mode

B. Transport mode

C. AH mode

D. Tunnel mode

A. It displays the energy consumption of network-wide devices.

B. It automatically powers off some wireless APs during energy-saving periods.

C. It automatically recommends energy-saving periods.

D. It automatically powers off switches.

A. Spectrum analysis

B. Mesh

C. WIPS

D. PMF
