10. You are designing an SRDF service level plan for a customer. Their needs assessment shows the
following:
Performance: Remote replication with potential impact, depending on distance and network latency for
synchronous leg
Availability: Zero data exposure in the event of a source failure; no data loss on a single point of failure
Functionality: Continuous real-time mirroring on synchronous leg, Unlimited distances with no additional
host impact for asynchronous leg, and the ability to synchronize between two remote sites
Economics: Requires sufficient bandwidth to support peak workload requirements
Which SRDF mode of operation should be chosen?
A.SRDF/A
B.SRDF/DM
C.SRDF/S
D.SRDF/Star

A.Block size is too small.
B.Read cache is turned off.
C.Sectors are misaligned.
D.Stripe size is too small.
Answer: C

the STDR2. A few minutes later the TimeFinder Integration Module for Exchange found inconsistencies in
the information store of the local STDR1 device. The SRDF link comes back up.
What must the storage administrator do next?
A.Restore the STD from the STDR2.
B.Establish the R1BCV with the STDR2.
C.Keep the data from becoming unusable at the remote location.
