E20-326 Online Practice Questions and Answers

A customer has a pair of VMAX arrays configured to replicate thin devices at one site to thin devices at another site using SRDF/A. The customer wants to implement TimeFinder/Clone replication of the R1 device on the source array and asks you to confirm this is a supported configuration. What do you advise the customer?

A. Yes, it is supported.

B. It is supported only if the precopy option is used.

C. No, it is not supported.

D. It is supported only if composite groups are used.

How is Open Replicator licensed?

A. Licenses are per-system and are priced by the raw capacity of the array. This is required for the control array only.

B. Licenses are per host and are priced based on an agent license that is entered via command line.

C. Licenses are per-system and are priced by the raw capacity of the array. This is required for both the remote and control arrays.

D. Licenses are per host and are priced based on the amount on the total amount of storage capacity that is mapped to an FA port.

Where is the pace set when using Open Replicator?

A. At the session level.

B. On the Host HBA.

C. On the Switch Port.

D. At the Symmetrix FA port.

What is the impact on response time when multiple concurrent writes to an RDF device arrive from different FA ports on a Symmetrix VMAX?

A. Concurrent SRDF/S writes will not help to improve response time.

B. Writes can run in parallel and response time is slightly improved.

C. Writes need to be finished before new writes arrive and negatively impacts response time.

D. Response time is mostly determined by the application write behavior.

A customer is planning a Tech Refresh. The proposed migration will make use of Open Replicator Hot Pull.

Which Open Replicator Hot Pull feature allows the customer to minimize the possibility of data loss during the migration?

A. Donor Update

B. Symmetrix Differential Data Facility

C. Protection Bitmap

D. Symmetrix Track Table

Which host-based performance tool should be used to gather data for Microsoft Windows systems?

A. PERFMON

B. SAR

C. IOSTAT

D. NAR

Which two tools should be used to compute the Capacity Available for Active Replication (CAAR)?

A. SymmMerge and Direct Express (Channel Express)

B. SymmMerge and Tier Advisor

C. BCSD and Direct Express (Channel Express)

D. BCSD and Tier Advisor

What is the EMC recommended network quality for SRDF/S over GigE?

A. Less than 0.01% packet loss

B. Less than 0.1% packet loss

C. Less than 0.25% packet loss

D. Less than 1% packet loss

A customer recently reconfigured their Microsoft Exchange 2010 environment. They placed the log and system files on the L:\ drive and mounted the mailbox stores on L:\SG1DBMP. The customer reports that they updated the associated Replication Manager replica job to reflect the change. However, the mounts to the backup server fail.

What should you advise the customer?

A. Mount both the logs and database to separate mount points within a folder on the C. drive

B. Additional clone targets need to be added to the storage pool.

C. Log and system files on same volume are not supported.

D. The mailbox store replica must be part of the same replica job as the log files.

A customer has implemented an Oracle application on a Symmetrix VMAX with a mix of Enterprise Flash Drives (EFD) and FC 15K drives. EFD are configured in RAID 5, and FC 15K drives are configured both in RAID 5 and RAID 1. In terms of IOPS activity, reads are predominant over writes. The customer decided to place a portion of the database in each tier.

Which Oracle database object(s) is suitable for placing on the FC 15K RAID 1 drives?

A. Redo log files

B. Data files

C. Index files

D. Temp file
