350-401 Question #565: Real Exam Question with Answer & Explanation

Question

An engineer must create a new SSID on a Cisco 9800 wireless LAN controller. The client has asked to use a pre-shared key for authentication. Which profile must the engineer edit to achieve this requirement?

Options

• ARF
• BPolicy
• CWLAN
• DFlex

Explanation

Explanation

On a Cisco 9800 Wireless LAN Controller (WLC), the WLAN profile is where you configure the core wireless network settings for an SSID, including the security parameters such as authentication type (WPA2/WPA3) and the pre-shared key (PSK). This is the logical starting point for defining what a wireless network is and how clients authenticate to it.

The RF profile (Option A) is incorrect because it controls radio frequency settings such as channel width, power levels, and data rates - not authentication. The Policy profile (Option B) is incorrect because it defines how clients are treated after they connect, handling QoS, VLAN assignment, and session timeouts. The Flex profile (Option D) is incorrect because it configures FlexConnect-specific behaviors for remote/branch APs operating in local switching mode.

💡 Memory Tip: Think "WLAN = Who gets in and how" - the WLAN profile is where you set the front door rules (SSID name, security type, PSK), while the Policy profile handles what happens inside after entry. If the question mentions authentication or security type, always think WLAN profile first.
