9. Question 119 · 197 in bank

   In preparation for a maintenance task, an LTM Specialist performs a "Force to Standby" on LTM device Unit 1. LTM device Unit 2 becomes active as expected. The maintenance task requires the reboot of Unit 1. Shortly after the reboot is complete, the LTM Specialist discovers that Unit 1 has become active and Unit 2 has returned to standby. What would cause this behavior?

   • AUnit 1 is set with the redundancy state preference of active in devices groups.
   • BUnit 1 is set with the redundancy state preference of active in high availability.
   • CA traffic group is configured with Auto Failback, and Unit 1 is the default device.
   • DA device group is configured with Auto Failback, and Unit 1 is the default device.
