D.
Secondary
Answers
D.
Secondary
Suggested answer: C

Explanation:

In a PowerFlex system, the SCLI (ScaleIO Command Line Interface) commands are typically performed on the Primary MDM (Metadata Manager). The Primary MDM is responsible for the overall management and operation of the cluster, including configuration changes and monitoring1. It is the authoritative source for metadata and cluster configuration, making it the primary point of interaction for administrative tasks.

The Tie-breaker and Standby MDMs serve as part of the high availability setup. The Tie-breaker MDM is used to avoid split-brain scenarios, and the Standby MDM is a backup that can take over the role of the Primary MDM if it fails. The Secondary MDM works in conjunction with the Primary MDM to manage the cluster but does not serve as the main point for executing SCLI commands.

Therefore, the correct answer is C. Primary, as it is the MDM where SCLI commands are executed for monitoring and managing the PowerFlex cluster.
