The System Admin role in PowerFlex Manager is primarily responsible for performing lifecycle operations. This includes tasks such as deploying, configuring, and updating the PowerFlex system components. The role is designed to manage the operational aspects of the PowerFlex environment, ensuring that the system is running efficiently and is up to date1.

While managing users and updating certificates are important administrative tasks, they are typically associated with different roles within the PowerFlex Manager’s user management system. For instance, managing users would fall under the purview of a User Admin role, which would handle the creation, modification, and deletion of user accounts. Updating certificates, on the other hand, would be more aligned with a Security Admin role, which would be responsible for maintaining the security aspects of the PowerFlex system, including certificate management1.

Therefore, the correct answer is A. Lifecycle operations, as it directly relates to the System Admin role’s responsibilities within PowerFlex Manager.
