A) SRDF/CG
B) SRDF/STAR
C) SRDF/EDP
D) SRDF/AR

2. A customer is using Virtual Provisioning on a Symmetrix V-Max array. A thin pool has been created and ten (10) 10 GB data devices have been added and enabled. The "Maximum Subscription Percent" has been set to 300.
How many 10 GB thin devices can be bound to the thin pool?

A) 10
B) 20
C) 60
D) 30

3. What is a feature of SRDF/A Group-Level Write Pacing?

A) Configured on RDF director level.
B) Can only be activated on R2 devices when the SRDF/A session is active.
C) Enables TimeFinder/Snap of R2 devices.
D) Extends its availability by preventing cache overflow.

4. Refer to the exhibit.

A database server has its logs stored on a volume on the log source Symmetrix V-Max array and its data stored on a volume on the data source Symmetrix V-Max array. Both source Symmetrix V-Max frames replicate data to the target Symmetrix V-Max at the disaster recovery site.
Two device groups have been defined:
- One group for the data volume on the Symmetrix containing the data LUNs
- One group for the log volume on the Symmetrix containing the log LUNs
What happens if the SRDF links between the Symmetrix containing the data LUNs and the target Symmetrix were to fail?

A) An SRDF failover would be initiated on all volumes and processing will automatically be switched over to the disaster recovery site.
B) The data in the database becomes inconsistent at the Remote Site.
C) The R2 data in the database remains consistent because Enginuity Consistency Assist (RDF-ECA) technology would ensure data consistency.
D) The R2 volumes in the Symmetrix V-Max containing the log LUNs would become write-disabled to the database server.

5. A customer's environment consists of several servers that require the presence of LUN #0 to function properly. What is the optimal way of attaching these servers to a Symmetrix V-Max array?

A) Allow servers to share FA ports while using dynamic LUN addressing
B) Use LUN offsets to make LUN #0 available to each server
C) Use device mapping to make LUN #0 available to each server
D) Connect the servers to different front-end ports on the Symmetrix
