QUESTION 5
Two RDF groups from two VMAX3 arrays have been added to a Consistency Group. SRDF/A Multi-Session
Consistency (MSC) has been enabled for the Consistency Group. The RDF daemon has been started on a single host
that has
access to both the VMAX3 arrays.
What will happen if this host becomes unavailable?
A. Cycle switching will stop
B. SRDF mode will change to Adaptive Copy Disk
C. RDF links will be suspended immediately
D. SRDF pair state will become Partitioned
Correct Answer: A
QUESTION 6
A storage administrator is using Unisphere for VMAX to provision storage to a virtual machine. This virtual machine
needs to share an RDM device that is already presented to another virtual machine. The administrator is unable to
select
the existing RDM to present to the virtual machine.
What could be the cause?
A. Volumes already presented as an RDM to other virtual machines are excluded from the available volumes list
B. Only available storage from datastores can be presented to virtual machines using Unisphere for VMAX
C. No volumes are available and a new volume cannot be created
D. Existing volumes can only be presented to physical hosts
Correct Answer: A
QUESTION 7
A VMAX3 system administrator needs to create a SRDF relationship for a planned data migration. Which replication
mode of SRDF is recommended for the initial bulk data transfer?
A. Adaptive Copy Disk
B. Synchronous
C. Asynchronous
D. Adaptive Copy Write Pending
Correct Answer: A
SRDF/Synchronous (SRDF/S), SRDF/Asynchronous (SRDF/A), and SRDF Adaptive Copy are the basic operation
modes of SRDF. The first two are valid for Oracle database protection and maintain dependent write-order consistency.
The third is useful for bulk data transfers or in combination with more complex SRDF solutions such as
SRDF/Automated Replication (SRDF/AR)
QUESTION 8
Refer to the Exhibit.
Production work has been resumed on the R2 devices after an SRDF Failover operation. Where will the changes made
to the R2 device be reflected in an SRDF Query?
A. 1
B. 2
C. 3
D. 4
Correct Answer: A
QUESTION 9
Storage has been provisioned from a VMAX3 using a Masking View with a single Storage Group associated with the
Bronze SLO. How can new storage be provisioned to this host using the Gold SLO while maintaining the original
volumes in the Bronze SLO?
A. Convert the existing Storage Group to cascaded, create a new child Storage Group for the new devices, and apply
the Gold SLO.
B. Apply the Gold SLO directly to the new volumes.
C. Add a cascaded Storage Group to the original Storage Group and apply the Gold SLO.
D. A new Masking View and Storage Group is required for the devices managed by the Gold SLO.
Correct Answer: A
QUESTION 10
What does Solutions Enabler use to determine the lockbox Stable System Values (SSVs) during installation?
A. Host hardware characteristics
B. User-defined password

QUESTION 13
What will happen if one or more source (R1) devices in an SRDF/Synchronous Consistency Group cannot propagate
data to their corresponding target (R2) devices?
A. Data propagation from all R1 devices in the Consistency Group to the R2 targets will be suspended
B. Data propagation from the specific R1 devices to their corresponding R2 targets will be suspended
C. SRDF/S replication will be suspended and consistent data cleanup will be performed on the R2 targets
D. All RDF device pairs in the Consistency Group will be set to Not Ready
Correct Answer: A
