• Question 215:

  What are characteristics of the LUN Snapshot Copy operation?

  A. Parent cannot be a snapshot copy Can only copy a detached snapshot Has an independent Retention Policy from the parent

  B. Parent can be a snapshot copy Can only copy a detached snapshot Has an independent Retention Policy from the parent

  C. Parent can be a snapshot copy Can copy an attached or detached snapshot Inherits the parent Snapshot Retention Policy

  D. Parent cannot be a snapshot copy Can copy an attached or detached snapshot Inherits the parent Snapshot Retention Policy

  Correct Answer: D

  The Snapshot Copy operation will make a copy of an existing snapshot that is either attached or detached from a host. The copy will capture the existing data state of the snapshot it copies. In this Copy example, a copy of an existing 4 o clock snapshot is being made. The copy inherits the parent snapshot data state of 4 o clock and its retention policy

• Question 216:

  What is used by the Local LUN Move data mobility feature?

  A. Transparent Data Transfer

  B. SANCopy push

  C. Inband Migration Tool

  D. Common base Snapshots
