Question
Options
- AOnly one
- BTwo, the cluster MVS and the unique Gateway MVS
- COne for each Virtual System configured on the Gateway
- DOne for each physical interface on the Gateway
- EOne for each cluster member
Explanation
In a VSX Gateway cluster, each cluster member runs exactly one Management Virtual System (MVS), which serves as the dedicated management plane for that member - handling management traffic, SIC (Secure Internal Communication), and policy installation for the entire VSX gateway. Option B is wrong because there is no architectural split between a "cluster MVS" and a "unique Gateway MVS"; the single MVS is the management entity regardless of cluster context. Option C is wrong because the number of configured Virtual Systems (data-plane VS instances) has no bearing on MVS count - the MVS is a fixed, singular management construct. Option D is wrong because physical interface count is irrelevant to MVS instantiation; the MVS is a logical construct, not tied to hardware. Option E is tempting but subtly wrong in framing - while it's true each member has a MVS, the answer is about how many per member, which is simply one.
Memory tip: Think of the MVS as the "manager's office" - no matter how many workers (Virtual Systems) or desks (interfaces) exist, there's only one manager's office per building (cluster member).
