A BIG-IP Administrator needs to make sure that the automatic update check feature works properly. What must the administrator configure on the BIG-IP system?

The "Update Check Schedule" directly dictates when and how often the BIG-IP system checks for new software updates. Without a defined schedule, the automatic update check feature cannot execute, as it lacks instructions on when to perform the update checks.

NTP servers are used for time synchronization but do not directly enable or control the automatic update check feature.

DNS name servers are essential for resolving hostnames to IP addresses (e.g., F5 update servers), but their configuration alone does not activate or schedule the update check process.

SMTP servers are configured for sending email notifications and are unrelated to the core functionality of checking for system updates.
