Question 6 of 158

What describes the LUN Snapshot Copy operation?

    Correct Answer: C

    The correct answer describes that the parent can be a snapshot copy, it can copy an attached or detached snapshot, and it inherits the parent snapshot retention policy. This accurately reflects how LUN snapshot copy operations function, as they allow flexibility in whether the snapshot is attached or detached and automatically inherit the retention policy from the parent snapshot.

Which technology is used by Unity Snapshots?

    Correct Answer: C

    Unity Snapshots employ the technology known as Redirect on Write. This method ensures that new writes to storage resources or their snapshots are redirected to a new location within the same pool, updating the pointers to reflect these changes. This allows for efficient management and storage of snapshots without overwriting original data.

What is the correct sequence of steps taken by the storage array when an AC power failure is detected?

Select and Place:

    Correct Answer:

    The Battery Backup Unit (BBU) provides power to the Storage Processor in the event that cabinet power is lost. The BBU is designed to power the SP long enough for the system to store SP cache content to the M.2 SSD device before powering down. The BBU includes sensors which communicate its charge and health status to the SP. In the event the BBU is discharged the SP will disable cache until the BBU has recharged. In the event the BBU has faulted or cannot sustain enough charge, an alert will be generated.

Question 9 of 158

A system administrator is configuring asynchronous remote replication for an existing NAS server and its' file systems on a Unity system. What should the administrator create to ensure all data is replicated for the NAS server and the file system?

    Correct Answer: D

    To ensure all data is replicated for both the NAS server and its file systems, a replication session for the NAS server must be created. This replicates the NAS server and all associated file systems automatically. Creating replication sessions only on individual file systems or both the NAS server and file systems separately is unnecessary and inefficient. Therefore, the correct approach is to create a replication session for only the NAS server.
