What is the default Minimum Scale per Virtual Service value in Active-Active HA, if one exists?
The correct answer is A. 2. In Active-Active HA mode, a minimum of 2 Service Engines per Virtual Service is required by design - the entire premise of Active-Active is that traffic is simultaneously distributed across multiple active nodes, so the system defaults the minimum to 2 to enforce that behavior…

Explanation
In Active-Active HA mode, a minimum of 2 Service Engines per Virtual Service is required by design - the entire premise of Active-Active is that traffic is simultaneously distributed across multiple active nodes, so the system defaults the minimum to 2 to enforce that behavior. Option B is wrong because a default does exist; the platform enforces this value to prevent misconfiguration. Option C (1) is incorrect because a single-instance deployment describes a standalone or Active-Standby arrangement, not Active-Active - one SE cannot be "active-active" by itself. Option D (3) is a plausible-sounding distractor but exceeds the baseline default; while you can scale higher, the minimum the system sets out of the box is 2.
Memory tip: Think "Active-Active = At least 2" - the double-A mirrors the number 2, reminding you that two active nodes is the floor, not the ceiling.
