Question 9 Discussion
Comments
Selected Answers: B
Explanation:
Traffic Groups in BIG-IP control which device is active for specific application traffic.
To move a traffic group from the current active device to another device (so maintenance can be performed), the administrator should fail over the traffic group.
This allows another BIG-IP in the device group to become active for that traffic group only, without forcing the entire device into standby.
Selected Answers: B
The correct option is B. Select Traffic Group and then select Failover.
Explanation:
Device Groups & Traffic Groups: In a BIG-IP HA setup, traffic groups manage the failover of virtual servers and related configurations between devices. One device is active (Primary), and others are Standby.
Failover (Option B): This action explicitly initiates a controlled failover of the active traffic group(s) to the next available standby device in the device group, which is exactly what's needed to move traffic off the primary for maintenance.
Force to Standby (Option C): While it moves the traffic, "Force to Standby" can be more abrupt and is often used in situations where you need to immediately take the primary offline, potentially causing brief disruption. "Failover" is the preferred method for planned maintenance.
Demote (Option D): Demoting a device makes it a standby, but it doesn't move an already active traffic group to it; it just changes the role of the device itself.
Selected Answers: C
A BIG-IP Administrator uses a device group to share the workload and needs to perform service on a BIG-IP device currently active for a traffic group. The administrator needs to enable the traffic group to run on another BIG-IP device in the device group. What should the administrator do to meet the requirement? (Choose one answer)
