1.A customer has installed Microsoft Windows Server 2008 Enterprise and is about to install Exchange
Server 2007. They will be connecting to a Symmetrix V-Max SE array and want to ensure the partitions
they create are properly aligned with the underlying physical disk tracks.
What is the recommended EMC and Microsoft best practice?
A. Create all partitions using the Windows Disk Management utility
B. Use the diskpar utility with the align=128 offset parameter
C. Use the diskpart utility with the align=64 offset parameter
D. Partition alignment is not necessary on the Symmetrix V-Max platform
Answer: A
2.A customer has an Microsoft Exchange Server 2007 database running on Windows Server 2008. The
Windows server contains users with dynamic mailbox growth requirements. In order to avoid
over-provisioning space while still allowing room for extended growth, the customer is considering
implementing Virtual Provisioning on their Symmetrix V-Max for this specific mailbox database.
The customer is trying to determine which option to use when performing a volume format on the NTFS
partition that will contain the mailbox database. Which option should be used and why.?
A. A quick format because it only performs a read request on the thin device and does not cause any
space to be allocated
B. A quick format because it will not take as long as a regular format on thin devices
C. A regular format because it will write zeros to every block in the file system, causing the thin device to
become fully allocated
D. A regular format because it will scan the entire volume for bad sectors
Answer: A
3.A customer has migrated a Microsoft Exchange 2007 server with several very active mailbox databases
to their Symmetrix V-Max. In addition, they have decided to integrate host-based fault tolerance by
utilizing Microsoft s nati ve conti nuous r epli ction technology.
Which database feature, provided by Exchange to reduce the chance of data loss, will also increase disk
capacity requirements on this busy mailbox server?
A. Lost Log Resilience
B. Replay Manager
C. Incremental Reseed
D. Transport Dumpster
Answer: A
4.A customer is migrating their Microsoft Exchange 2007 server from a NAS back end to a new
Symmetrix V-Max SE array. Perfmon was used to create a log view of an average day's activity against
the database LUN of the busiest datastore in the Exchange environment. This will serve as the
performance benchmark for all other database LUNs. There are an additional four mailbox databases on
this server.
How many RAID 1-protected 15k rpm spindles are required to satisfy the performance needs of the
customer for all the mailbox databases on this server?
A. 10
B. 26

8.A customer is using the TimeFinder/Exchange Integration Module (TF/EIM) to back up multiple
Microsoft Exchange 2007 mailbox servers, each with a different SLA. They have configured an
initialization file defining the options to be used when performing VSS backups of each Exchange storage

10.A customer has implemented Cluster Continuous Replication with a Majority Node Set cluster
configuration for a critical mailbox server. They are using Replication Manager to create daily replicas of
five storage groups on the mailbox server, each containing a single mailbox database.
The customer notices that logical corruption has been introduced in one of the databases being backed
up with Replication Manager. They attempt to perform a point-in-time restore of the corrupted database,
but the restore process fails.

B. An attempt to restore to the Active Node in the cluster
C. File Share Witness is not responding
D. Shared quorum volume is not available
Answer: A

environment.
In addition, the customer has created a scheduled job to create replicas of five storage groups in
consecutive order. Since doing so, they notice that the newly added replica jobs seem to take a very long
time to complete.

13.A customer has implemented Microsoft Exchange Server 2007 in an SRDF environment with replicas
being taken at the disaster recovery (DR) site. During testing of this solution, they have failed over

Controller
B. Recover the database from the BCV copies available at the DR site
C. Ensure that the World Wide Web service on the Exchange server at the DR site has started

successfully
D. Recover the database from the remote BCV copies available at the primary site
Answer: A
14.A customer wants to provide remote disaster recovery (DR) for several critical mailbox servers in their
Microsoft Exchange Server 2007 environment. Local recoverability is provided by creating replicas of their
critical databases.
The customer's DR site is located 20 km away. They have already provisioned the necessary failover host
on the DR site, as well as the required Active Directory infrastructure needed to support a failover.
However, they want to minimize the total number of database copies required to provide basic failover
capabilities for the Exchange server.
Which solution would you recommend to provide remote point-of-failure recovery with the fewest local
and remote database copies?
A. R1-R2-BCV
B. Mixed Mirroring
C. STD-R1BCV-R2-BRBCV
D. STD-R1BCV-R2
Answer: A
15.A customer wants to use TimeFinder/Exchange Integration Module (TF/EIM) to create daily local
replicas of a critical Microsoft Exchange 2007 mailbox server. Using Terminal Services, they connect
remotely to the backup server and execute the following command:
exbackup2007 -v -vss -s [servername\] -preestablish
The command runs up until the point where TF/EIM attempts to mount the volumes, then it fails. Why is
the process unable to complete?
A. Exbackup is not supported using a terminal session
B. Correct VSS Provider was not installed
C. "copyonly" switch must be specified the first time a backup is run
D. Exbackup does not have the permissions needed to run on the backup host
Answer: A
