maintenance window and activate the session during the maintenance window
C. Create a hot pull session with the precopy option from the DMX prior to the maintenance
window and activate the session during the maintenance window
D. Activate a hot push session with the precopy option from the VMAX prior to the
maintenance window and activate the session during the maintenance window
Answer: A

Symmetrix VMAX 40K array. What happens when the Federated Live Migration session is
created?
A. VMAX devices assume the geometry and identity of the DMX devices
B. DMX devices assume the geometry and identity of the VMAX devices
C. DMX devices are set to Not Ready and VMAX devices are set to Host Passive
D. VMAX devices are set to Not Ready and DMX devices are set to Host Passive
Answer: A
An application host is zoned to FAs 7E:0 and 10E:0. The RecoverPoint appliances are
zoned to FAs 8E:0 and 11E:0 of the same VMAX 10K. LUNs have been masked to the
RecoverPoint appliances. The RecoverPoint splitter is unable to split the writes to the
LUNs. What requirement for using RecoverPoint has not been met?
A. RecoverPoint appliances must be zoned to the same FA ports as the replicated host
B. The replicated LUN must be configured as an SRDF/R1 device
C. RecoverPoint appliances must be zoned to a minimum of 4 FA ports
D. The RecoverPoint splitter is only available for use with the VMAX 20K and VMAX40K.
Answer: A
Which underlying product is used by the Symmetrix RecoverPoint splitter?
A. Open Replicator
B. TimeFinder
C. SRDF
D. FLM
Answer: A
Where on a Symmetrix is the I/O split for RecoverPoint?

C. Rename the default pool.
D. Associate the SRDF group with the default pool.
Answer: A
Click on the calculator icon in the upper left. A customer requested assistance in using the
symcli symconfigure command to create one 8-way 1 TB striped meta bound to POOL_A.
Which parameters do you provide?
A. Create dev count=1, size=1118480 cyl, config=tdev, emulation=fba,
meta_member_size=139810, meta_config=striped, binding to pool=POOL_A

What is an optimized read miss on a Symmetrix VMAX 40K?
A. In case of a read miss, the data read from the backend disk is sent directly to the FA
buffer bypassing the cache.
B. In case of a read miss, the optimizer moves the requested tracks to other spindles with
lower utilization for faster processing.
C. In case of a read miss, the read and pre-fetch operations are optimized by reading 8
subsequent tracks of data and loading them on cache.
D. In case of a read miss, I/O is quiesced on the FA to avoid buffer overflow until the
requested I/O is delivered to the FA.
Answer: A
