220-1102 Question #649: Real Exam Question with Answer & Explanation

Question

An enterprise user cannot authenticate to the office Wi-Fi. Which of the following steps should most likely be taken to resolve the issue?

Options

• AReinstall the OS.
• BCheck the machine's certificates.
• CResync the Group Policy.
• DPower cycle the switch.

Explanation

For an enterprise user unable to authenticate to Wi-Fi, especially in a secure environment often using 802.1X, checking the machine's certificates is a critical step as expired or incorrect certificates can prevent successful authentication.

Common mistakes.

• A. Reinstalling the OS is a drastic and time-consuming measure that should be a last resort after extensive troubleshooting, not an initial step for a Wi-Fi authentication issue.
• C. Resyncing Group Policy primarily refreshes policy settings and might not directly address a certificate-based authentication failure if the certificate itself is the issue.
• D. Power cycling the switch would affect all users connected to that switch and is unlikely to resolve an issue specific to one user's machine authentication.
