the control host be configured?
A. A dedicated channel to the gatekeeper devices
B. Access to only the target devices
C. Access to only the source devices
D. PowerPath must be installed on the host
Answer: A

Answer: A
QUESTION 3
What will happen if one or more source (R1) devices in an SRDF/S 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 a 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
Answer: A
QUESTION 4
What is the result if one or more source (R1) devices in an SRDF/S consistency group cannot
propagate data to their corresponding target (R2) devices?
A. RDF daemon trips the consistency group, thereby suspending data propagation from all R1 devices
B. Target (R2) devices will be Read/Write Enabled at the R2 site
C. PowerPath suspends data propagation to the R1 devices in the consistency group
D. RDF daemon suspends the data propagation from the affected R1 devices while maintaining consistency
among the remaining devices
Answer: A

VMAX array. What is recommended before starting the Open Replicator session?
A. Ensure that the remote devices are not host accessible
B. Ensure that the remote devices are host Read/Write Enabled
C. Ensure that the control devices are Not Ready
D. Ensure that the control devices are Write Disabled
Answer: A
QUESTION 9
Open Replicator Cold Push will be used to move data between a Symmetrix VMAX array and a
third-party array. What needs to be done before creating the Open Replicator session?
A. Set the control devices to Not Ready
B. Set the remote devices to Not Ready
C. Set the control devices to Read/Write
D. Set a device reservation on the remote devices
Answer: A
QUESTION 10
A customer is planning to migrate data belonging to two applications (i.e., A and B) from an older
array to a new Symmetrix VMAX. Both migrations will run in parallel. However, it is necessary to
transfer data from application A (session A) as fast as possible. The data from application B
(session B) can be transferred at a slower rate.
Which settings should be used to run the two sessions?
A. The pace of session A should be set to 0.
The pace for session B should be set to 9.
B. The pace for session A should be set to 9.
The pace for session B should be set to 0.
C. Session A should be assigned to a Fibre Channel director with a ceiling setting of 100.
Session B should be assigned to a different director with a ceiling value of 10.
D. Session A should be assigned to a Fibre Channel director with a ceiling setting of 10.
Session B should be assigned to a different director with a ceiling value of 100.
