Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 253

A wireless network uses Cisco ISE to implement 802 1x for user authentication and an Active Directory server as a user database. After a power outage, the wireless clients cannot connect to the wireless network. The ISE log reports a "clock skew". Which action addresses this issue?

Answer options

• A. Install a trusted certificate.
• B. Enter the correct credentials.
• C. Restart the ISE service.
• D. Configure NTR.

Correct answer: D

Explanation

The 'clock skew' error typically indicates a time synchronization issue between the ISE and the Active Directory server. Configuring Network Time Protocol (NTP) (option D) ensures that both systems maintain the same time, resolving the skew. The other options do not address time synchronization issues directly, making them ineffective for this specific problem.
