1. A customer is migrating from Microsoft Exchange 2003 to Exchange 2007. The customer is trying to estimate the user load profile that fits their environment for the purposes of sizing the disk subsystem.
Which condition could cause the customer to underestimate the IOPS required for their environment?
A. Database maintenance
B. Deleted items retention
C. Mobile device users
D. Nested subfolders with many thousands of items
Answer: C

2. A customer is migrating from Microsoft Exchange 2003 to Exchange 2007. They want to provision each mailbox server with 2,000 users, allowing for 100 “heavy” profile users per Exchange storage group. In designing an SLA for the customer, you determine that the customer requires the use of recovery storage groups for disaster recovery purposes.
Which consideration must be made when architecting this solution?
A. A maximum of 50 production storage groups can be hosted per Exchange Server
B. A maximum of four production storage groups can be hosted per Exchange Server
C. Exchange 2007 Enterprise Edition is required
D. Server hosting the recovery storage group must be in a separate Active Directory forest from the source storage groups
Answer: C

3. A customer is consolidating 2,000 seats from Lotus Notes to one Microsoft Exchange 2007 server. They want to provision each Exchange storage group allowing for 100 “Very Heavy” profile users. Mailbox quotas are set at 500 MB per mailbox. Deleted item recovery is set to the defaults and a full pass of database maintenance completes nightly. Content indexing is enabled and the customer has no need for offline maintenance.
What is the minimum LUN size that can be allocated for each Exchange Storage Group’s database, while meeting the customer’s needs?
A. 25 GB
B. 113 GB
C. 119 GB
D. 133 GB
Answer: C

4. A customer is consolidating 2,000 seats from Lotus Notes to one Microsoft Exchange 2007 server. They want to provision each Exchange storage group allowing for 100 “Heavy” profile users. Mailbox quotas are set at 500 MB per mailbox.
Deleted item recovery is set to the defaults and a full pass of database maintenance takes 48 hours to complete. Content indexing is enabled and the customer has no need for offline maintenance.
What is the minimum LUN size that can be allocated for each Exchange Storage Group’s database, while meeting the customer’s needs?
A. 25 GB
B. 95 GB
C. 100 GB
D. 125 GB
Answer: C

5. A customer has noticed that performance is degraded on one of their Microsoft Exchange servers after migrating all Exchange 2003 servers to Exchange 2007. Analysis indicated that the system is performing two reads for every transaction.
What is the most probable cause?
A. Block size is too small
B. Cache is disabled
C. Sector misalignment
D. Stripe size is too small
Answer: C

6. A customer is implementing Replication Manager 5.1.3 to create BCV replicas against a Microsoft Exchange 2007 server. The Exchange server has two sets of STD devices: one set running the production LUNs and the other acting as a local continuous replication destination.
The customer would like an application consistent BCV replica of the production LUN with minimal impact on the production LUN. How should the Replication Manager job be configured?
A. A file system job should be configured against the local continuous replication target LUN(s)
B. A file system job should be configured against the production Exchange LUN(s)
C. An Exchange job should be configured against the local continuous replication target LUN(s)
D. An Exchange job should be configured against the production Exchange LUN(s)
Answer: D

7. A customer wants to use Replication Manager to create application consistent BCV copies of their Microsoft Exchange 2007 server running Cluster Continuous Replication (CCR). They would like to create the replica from the passive copy of the CCR storage group, regardless of which physical node in the cluster currently hosts that role.
What is your recommendation?
A. Replication Manager can replicate only the active copy of a CCR cluster
B. Use combination replication to replicate the CCR storage group
C. Use node-based replication of the CCR storage group
D. Use role-based replication of the CCR storage group
Answer: D

8. You are designing a Replication Manager solution to provide VSS backups of Exchange 2007 with TimeFinder/Clone. What should you take into consideration?
A. A maximum of five databases per storage group is supported
B. Circular logging must be disabled
C. Transaction Log and database paths must be the same
D. Transaction Log and system path cannot be on the same device
Answer: B
