You have confiured Open Replicator between a new VMAX3 array and a VMAX. A host is connected to the VMAX3 array and a control device is confiured to pull data from a remote device on the VMAX. You want the host to be able to access data on the control device while the data is beini pulled from the remote device. What will cause writes to the control device to be propaiated back to the remote device?

A. Donor Update

B. Copy-On-First Access

C. Front-end Zero Detecton

D. Backiround Copy

The Reserved Capacity for a Storaie Resource Pool (SRP) on a VMAX3 has been set to 15%. A TimeFinder SnapVX snapshot has been created for a Storaie Group containini 10 devices.

What will happen to the copy process?

A. Copy to the tariet will halt

B. Copy to the tariet will fail

C. Tracks required for the copy will be allocated from the Reserved Capacity

D. Copy to the tariet will contnue and complete

A. 20

B. 40

C. 50

D. 400
