A customer needs to migrate data to a new database environment. They need to make a physical
copy of their data that can be presented to the new environment with the highest level of
availability. Which form of replication should the customer use?

A.
backups to disk

B.
snapshots

C.
clones

D.
asynchronous replication

Explanation:

Incorrect:
Not B: A storage snapshot is a set of reference markers, or pointers, to data stored on a disk drive,
on a tape, or in a storage area network (SAN). A snapshot is something like a detailed table of
contents, but it is treated by the computer as a complete data backup. Snapshots streamline access
to stored data and can speed up the process of data recovery. There are two main types of storage
snapshot, called the copy-on-write (or low-capacity) snapshot and the split-mirror snapshot. Utilities
are available that can automatically generate either type.
