A customer wants to configure a large SRDF deployment between two VMAX3 arrays. The customer has many different applications and workloads. They want to separate each into its own SRDF group.
What is the maximum number of SRDF groups this configuration will support?

A customer has production and disaster recovery VMAX3 arrays. There is limited bandwidth between the sites. The amount of data which will be replicated by using SRDF to the disaster recovery site is slightly more than the available bandwidth allows.
Which action is needed to accommodate the customers need?

A customer is using two VMAX3 arrays with a compression module installed on both arrays. After careful monitoring of the SRDF traffic, they discover that the data is not being compressed.
What additional action needs to be performed to enable compression?

You have configured Open Replicator between a new VMAX3 array and a VMAX. A host is connected to the VMAX3 array and a control device is configured 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 being pulled from the remote device.
What will cause writes to the control device to be propagated back to the remote device?

A customer needs to automate SRDF disaster recovery for a Microsoft cluster. Which SRDF solution is recommended?

When data consistency is not a requirement, which SRDF mode is preferred when replicating large volumes of data?

The Reserved Capacity for a Storage Resource Pool (SRP) on a VMAX3 has been set to 15%. A TimeFinder SnapVX snapshot has been created for a Storage
Group containing 10 devices. An application is actively performing read and write I/Os to these devices. Allocation for the SRP reaches 85%.
What will happen to the snapshot?

The Reserved Capacity for a Storage Resource Pool (SRP) on a VMAX3 has been set to 15%. A TimeFinder SnapVX snapshot has been created for a Storage
Group containing 10 devices. An application is actively performing read and write I/Os to these devices. The snapshot is linked to the target in Copy mode.
Allocation for the SRP reaches 85%.

What will happen to the copy process?

A TimeFinder SnapVX snapshot of source volumes has been linked to target volumes. The target volumes are being used for application testing.
What is recommended prior to a relink operation?

A TimeFinder SnapVX snapshot of source volumes has been linked to target volumes. The target volumes are being used for application testing.
What is recommended prior to restoring from the snapshot?

A storage administrator attempts to link a TimeFinder SnapVX snapshot to a target Storage Group using Unisphere for VMAX. Which Storage Groups (SGs) will be available?

A VMAX3 customer has linked a TimeFinder SnapVX snapshot to a target in Copy mode. The copy has completed. Which operation will disassociate the linked target and provide a full usable copy?

How can a TimeFinder SnapVX snapshot be terminated when there are linked targets in NoCopy mode?

A TimeFinder SnapVX snapshot of source volumes has been linked to target volumes. Target volumes are accessed by a host and changes are made. These changes need to be copied back to the source volumes.
Which mode should the target have been linked to enable a restore from them?

A storage administrator has completed TimeFinder SnapVX testing. The administrator is unable to terminate the TimeFinder SnapVX snapshot of the test Storage
Group.
What advice should be provided to the administrator?

A storage administrator began taking nightly TimeFinder SnapVX snapshots of Oracle database LUNs 7 days ago. The administrator reports that the snapshots failed the previous night.
What advice should be provided to the administrator?

The Storage Group containing the source volumes on a VMAX3 array is managed by the Gold SLO. A TimeFinder SnapVX snapshot of this Storage Group is linked to target volumes. The Storage Group containing the target volumes is managed by the Bronze SLO.
Which SLO will be used to manage the snapshot deltas?

A TimeFinder SnapVX snapshot of the Storage Group containing four devices is created at 10 AM. The storage administrator adds another device to this Storage
Group at 2 PM. The snapshot is used to perform a restore operation at 3 PM.
What will be the status of the newly added device after the restore operation?

A TimeFinder SnapVX snapshot of the Storage Group containing four devices is created at 10 AM. The storage administrator adds another device to this Storage
Group at 2 PM. A second snapshot of the Storage Group is created at 3 PM. The 3 PM snapshot is used to perform a restore operation at 4 PM.
What will be the status of the newly added device after the restore operation?

A company is using a VMAX3 at each of their two sites. They have allowed hosts to write data to both the R1 and R2 devices. They decide that the data on the R1 site is the actual production data and need to start replicating data from R1 to the R2 site again.
Which operation will discard the new data on the R2 and resume replication?

SRDF/A has been enabled between two VMAX3 arrays. What is the benefit of SRDF/A Multi-Cycle mode?

What will be the status of the links in a query after an SRDF suspend operation?

Which SRDF remote replication licenses are available with VMAX3?

You are planning a migration from a VMAX to a new VMAX3. What will allow SRDF device pairing when the source device is configured with an odd number of cylinders?

A storage administrator needs to add three newly created RDF devices into an already existing asynchronous SRDF group. What are the appropriate steps to achieve this goal?
