質問 # 59
A customer has a fully scaled-out Dell PowerStore T cluster and wants to ensure that PowerStore Manager is in a highly available configuration How many instances of PowerStore Manager should be installed, and why?

A. Four A customer should install one instance per appliance in the cluster
B. Two PowerStore Manager needs at least two instances for a highly available configuration
C. Zero PowerStore Manager runs highly available by default
D. Eight A customer should install one instance per node in the cluster

正解：B

解説：
Explanation
A fully scaled-out Dell PowerStore T cluster requires at least two instances of PowerStore Manager to ensure high availability. This is because the PowerStore Manager provides a centralized management and monitoring interface for the cluster, and having multiple instances of it allows for redundancy in case one instance becomes unavailable.
