A customer wants to protect production data using local and remote replication on a pair of
VMAX arrays located 100 km apart. Both VMAX arrays are fully configured with virtually
provisioned thin volumes. The customer has a near zero Recovery Point Objective (RPO)
and wants to replicate the production volumes to the remote array, while maintaining a
separate backup copy of the production data on the local array. Which replication options do
you recommend they implement?

A customer wants to protect production data using local and remote replication on a pair of
VMAX arrays located 500 km apart. Both VMAX arrays are fully configured with virtually
provisioned thin volumes. The customer has a Recovery Point Objective (RPO) of thirty
minutes and wants to replicate the production volumes to the remote array while maintaining
a separate backup copy on the local array. Which replication options do you recommend
they implement?

Your customer is interested in using Timefinder/Snap. You have determined there needs to
be fifty save devices to handle the change rate for 125 virtual devices. The Save devices
and the virtual devices are the same size. What should be recommended if source volume
performance is a consideration?

When using Timefinder/SNAP, what is true of Save devices?

Changes were made to a TimeFinder Clone after activation. The changes need to be
propagated back to the source. Which method should be used?

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.?

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)?

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
tell 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?
