F5CAB4 Exam Dumps : BIG-IP Administration Control Plane Administration (F5CAB4) exam

Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents: In a High Availability pair, the "Force to Standby" action is a Control Plane command used to trigger a manual failover. This option is only logical and available on the device that is currently in the Active state. If the button is greyed out, it indicates that the administrator is already logged into the Standby unit, which has no active traffic groups to relinquish.

Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:This log message indicates that the system is low on memory and has activated 'Aggressive Mode' to reclaim resources by closing old connections37. In an HA environment, one way to ensure state stability during memory pressure is to manage how connection data is handled38. While the document suggests D, procedural mitigation for 'Aggressive Mode' often involves reviewing resource provisioning or optimizing connection idle timeouts to reduce memory footprint39.

Comprehensive and Detailed Explanation From BIG-IP Administration Control Plane Administration documents:

On BIG-IP systems that participate in a Device Service Cluster (DSC), each device compares theremote device’ssystem time to itsownsystem time. If the difference is outside theConfigSync time threshold(commonly referenced as3 seconds by default), BIG-IP updates the shell prompt to show“Peer Time Out of Sync”, andConfigSync operations may failuntil time is corrected (typically by fixing NTP reachability/configuration, or in some cases adjusting the threshold).

This message is specifically abouttime drift between peersin the trust domain/DSC—not basic reachability (soBis not what it means), and it doesnotprove which side is “correct” (soCis too specific). It also doesn’t directly mean an NTP source is “skewed” (A can be acause, but the prompt message itself indicates thepeer-to-peer time mismatchcondition). (cdn.studio.f5.com)
