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?
