Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 834

An engineer must update the local web authentication details on a Cisco 5520 WLC. The engineer has one active SSID configured for web authentication and plans to update the virtual interface with a nonroutable IP address. Which command must the engineer apply?

Answer options

• A. config wlan create wlan_idname
• B. config interface address virtual 1.1.1.1
• C. config interface address dynamic-interface virtual 192.0.2.1
• D. config interface address virtual 192.0.2.1

Correct answer: D

Explanation

The correct command is D because it directly sets the virtual interface to the specified nonroutable IP address. Option A is for creating a WLAN, which is not relevant to updating the virtual interface. Option B provides a nonroutable IP but is not the correct command format, and option C pertains to dynamic interfaces rather than the virtual interface needed in this scenario.
