Which solution do you recommend to the customer?
A customer has a Windows-only environment connected to an EMC VNX for File at their main
campus site. The customer plans to install a new EMC VNX at a remote branch office site. The
new VNX will be used to implement a DR solution for their main campus VNX using several
deduplicated file systems shared and available to clients via CIFS.

What is this time period called?
A customer has a requirement to restore operations within two hours after a disaster. What is this
time period called?
What would you recommend?
A system administrator wants to migrate medical-imaging data stored on an EMC VNX. The host
connects to the VNX via iSCSI. The IP SAN infrastructure has recently been updated to support 1
Gb/10 GB switching. The system administrator wants to maximize data transfer performance.

How many backups are required to perform a full system restore as of Friday morning?
A full backup of a file system is performed once a week on Saturday and cumulative backups are
performed on all other days. Backups start at 20:00 with a two-hour window. Data on the file system
changes every day. How many backups are required to perform a full system restore as of Friday
morning?
What would you advise the customer?
A customer has a CIFS DR solution with EMC VNX using a One-to-Many replication topology. The
customer asks you to explain replication behavior under the following conditions:
• Production site failover or switchover to a DR site
• Replication start and reverse is performed
What would you advise the customer?
What is this process called?
A customer is moving data from a backup disk to tape, which will later will be stored offsite.
What is this process called?
what is the total number of spindles required to generate the required I/O per second?
Click on the calculator icon in the upper left-hand corner.
A SQL database requires 1,000 I/O per second with 85% reads and 15% writes. If RAID 1/0 is
used, what is the total number of spindles required to generate the required I/O per second?
which factor is most significant when determining how long to keep the backup data on disk?
You are planning the staging policy for disk-to-offsite tape backup media. In addition to available disk
space, which factor is most significant when determining how long to keep the backup data on disk?
Why does CIFS replication not failover to the target VNX during the DR test?
A customer has two EMC VNX configured to replicate between sites. Each VNX has dual Control
Stations. The primary Control Station at the source site fails at 6 p.m. and reboots. At 8 p.m., the
customer completes DR testing and observes CIFS replication does not failover to the target site
VNX. Why does CIFS replication not failover to the target VNX during the DR test?
