The LUN Snapshot Attach to Host operation is being performed with Read/Write Access selected. By default, what does the Dell Unity XT system do before beginning the attach process?

Explanation

When attaching a LUN Snapshot with Read/Write Access, the Dell Unity XT automatically creates a copy of the Snapshot before proceeding. This is because R/W access would allow the attached host to modify the data - and allowing direct writes to the original snapshot would corrupt its point-in-time integrity. By copying the snapshot first, the system hands the host a safe, writable clone while preserving the original snapshot unchanged.

Why the distractors are wrong:

• B - Detaching other hosts from the snapshot tree is not a prerequisite step; existing host attachments are handled independently.
• C - The system doesn't concern itself with what other LUNs' snapshots the host is connected to; that's unrelated to this operation.
• D - Creating a new snapshot of the LUN (not the snapshot) is a separate operation and would be redundant here - the snapshot itself already captures the LUN's state.

Memory tip: Think "R/W = Risk to the original." Whenever write access is requested, Unity XT plays it safe by making a copy first - like photocopying a document before letting someone write on it.
