F5 TMOS Administration — Question 23

When upgrading a BIG-IP redundant pair, what happens when one system has been updated but the other has not?

Answer options

• A. Synching should not be performed.
• B. The first system to be updated will assume the Active role.
• C. This is not possible since both systems are updated simultaneously.
• D. The older system will issue SNMP traps indicating a communication error with the partner.

Correct answer: A

Explanation

The correct answer is A because synchronization between the two systems should be avoided to prevent inconsistencies. Option B is incorrect because the system that is updated first does not automatically become Active until both are on the same version. Option C is false since upgrades can occur sequentially, and option D is not accurate as SNMP traps are not necessarily triggered solely by version discrepancies.
