An administrator wants to schedule signature updates to occur at 3:00 AM daily. Where is this configured?
Device > Dynamic Updates provides the scheduled signature update setting, where a recurring daily time is defined for the firewall to fetch new content versions. This directly satisfies the 3:00 AM daily requirement, unlike manual or threshold-based update methods that cannot enforce a fixed schedule.
Why this answer
The Device > Dynamic Updates page contains the schedule settings for various update types like Applications, Threats, and WildFire.
