During the routine maintenance of the wireless network, engineers use the traditional WLAN network operation and maintenance method to view information on the wireless controller web interface…

Question

Options

• AWireless controller license status
• BMemory usage of wireless controller
• CCPU usage of wireless controller
• DAP CPU utilization

• A
  100% (36)

Explanation

All four options are correct because a wireless controller's web interface serves as a centralized management dashboard that exposes both the controller's own health metrics and the status of all managed devices. License status (A) is surfaced on the web UI because administrators need quick visibility into feature entitlements without using the CLI. The controller's memory (B) and CPU (C) usage are standard system resource metrics available on any management interface, letting engineers spot performance bottlenecks at a glance. AP CPU utilization (D) is also queryable because the controller aggregates telemetry from every associated AP and presents it centrally - this is a core value proposition of controller-based WLAN architecture.

Since this is an all-of-the-above question with no wrong options, the exam is testing whether candidates underestimate the web interface's scope - specifically, whether they mistakenly believe AP-level metrics (D) require direct AP access rather than being visible through the controller.

Memory tip: Think of the wireless controller web UI as a "single pane of glass" - it shows its own health (license, CPU, memory) and the health of every AP it manages. If the controller owns it, the web UI shows it.
