Which method should be used?
Changes were made to a TimeFinder Clone after activation. The changes need to be propagated
back to the source. Which method should be used?
What is the first step needed to create a snap from the same source device at 9:00 p.m.?
A customer has taken four snaps of a TimeFinder/Snap source device at 10:00 a.m., 1:00 p.m.,
3:00 p.m. and 5:00 p.m. A restore operation is performed at 8:00 p.m. from the 5:00 p.m. snap
session. What is the first step needed to create a snap from the same source device at 9:00 p.m.?
what is the effect on the ability to access the data on the VDEV?
When terminating a TimeFinder/Snap session, what is the effect on the ability to access the data
on the VDEV?
What describes the difference between Asynchronous and Synchronous Copy on First Write (COFW)?
What describes the difference between Asynchronous and Synchronous Copy on First Write
(COFW)?
What do you tell the customer?
An existing TimeFinder customer migrated from a DMX-3 running Enginuity 5771 to a new VMAX
array. They ask you to explain how the TimeFinder/Clone Copy on First Write (COFW) mechanism
on the new VMAX array differs from their DMX-3 array.

What do you advise the customer?
An existing TimeFinder customer migrated from a DMX-3 running Enginuity 5771 to a new VMAX
array. A colleague advised them TimeFinder/Clone performance would improve on the VMAX due
to changes to the Copy on First Write (COFW) mechanism. The customer asks you to explain how
the COFW mechanism changed on the VMAX.

What do you advise the customer?
A customer has a pair of VMAX arrays configured to replicate thin devices at one site to thin
devices at another site using SRDF/A. The customer wants to implement TimeFinder/Clone
replication of the R2 device on the target array and asks you to confirm this is a supported
configuration. What do you advise the customer?
