QUESTION 3
An administrator receives an escalation to investigate a low disk space alarm on a datastore. The
administrator discovers that a snapshot has been accidentally taken on a
production, write-intensive database server. The snapshot has grown to nearly 1 TB in size in less than an
hour and continues growing every second.
Which behavior should the administrator expect while deleting the snapshot? (Choose the best answer.)
A. ESXi will create a virtual RAM disk to cache ongoing database write activity; performance impact will be
limited.
B. ESXi will commit the snapshot delta disk into the base disk; ongoing database write activity could result
in long stun times.
