NO.7 A pair of VNX storage arrays is replicating between two data centers over an iSCSI connection. The
SQL Admin has noticed that a small OLTP database with a write size of 4k periodically experiences
increased disk response times. The Storage Admin reports that during the same period, replication
sessions are taking longer to complete. The Network Admin reports degraded performance between the
sites during the same period.
Why is the SQL application seeing increased disk response times from the local array?
A. Increased latency causes the MirrorView/A update cycles to take longer, increasing COFW activity.
B. The 64 KB chunk size for MirrorView/A does not match the small transaction size of the database,
increasing the bandwidth required between the arrays.
C. The MirrorView/A update cycle time is too short. It should be increased to improve write folding.
D. The MirrorView/A buffer size should be adjusted to match the smaller write I/O size.

NO.14 A SQL Data Warehouse database is replicating between two VNX storage systems with Incremental
San Copy. The production database is on 15, 15k rpm SAS drives and the Reserved LUN Pool uses five
NL-SAS drives. The database is continuously updated locally and replicated once a day to maximize the
benefits of write folding. Replication takes place from 6 PM until 10 PM. At 6 PM the storage administrator
notices an increase in response time of the application, which steadily improves until 10 PM.
What should be done to improve performance during replication without affecting recovery data
granularity?
A. Put the Reserve LUN Pool on a similar disk and RAID type as the source volume.
B. Create a clone of the source volume and replicate the clone.
C. Expand the number of drives in the source volume to accommodate the increased I/O from the
replication session.
D. Adjust the San Copy throttle to minimize the impact to the production application.
