An EMC NetWorker customer is considering implementing NetWorker AES encryption to secure backups on one of their application servers.
What is a concern when using AES?
A. Increased CPU utilization on the backup client
B. Tape must be used as a destination device
C. Backup data cannot be multiplexed
D. Increased CPU utilization on the backup server
The EMC account team has been asked to design a NetWorker backup solution for a Microsoft Exchange server. The customer's environment consists of a Microsoft Exchange Server 2007 Cluster Continuous Replication (CCR) deployment on a CLARiiON disk array with EMC VSS Provider and an EMC Disk Library.
The customer wants to leverage the Microsoft VSS framework to protect the Exchange Server 2007 CCR environment. What needs to be considered when designing a backup solution?
A. Exchange server can be backed up from the Exchange Server 2007 CCR passive node
B. Exchange server can only be backed up through a Proxy Node
C. Microsoft Exchange Server 2007 database and transaction logs must reside on the same volume
D. Microsoft Exchange Server 2007 system path and transaction logs must reside on separate directories

A. Backup from the Exchange Server 2007 CCR passive node will fail after Exchange Server 2007 CCR role change
B. NetWorker Module for Exchange needs to be installed on both the Exchange Server 2007 CCR active node and passive node
C. Exchange Server 2007 database and transaction logs must reside on the same volume
D. Exchange Server 2007 system path and transaction logs must reside on separate directories
A customer has two files that have been locked and backed up to the Data Domain appliance with the following parameters:
File1 = atime = 20 years File2 = atime = 5 years
The Data Domain global retention periods are configured as follows:
Min = 2 years Max = 10 years
The administrator changes the Data Domain maximum retention period to 4 years. After how many years can File2 be deleted?
A. 2
B. 4
C. 5
D. 10
A customer performs weekly full backups and daily incremental backups. A typical full backup is 5 TB. There is usually a 20% daily change rate in data. A full backup completes in 10 hours while an incremental backup completes in 4 hours.
Based on best practices, what is the minimum Data Domain throughput required?
A. 292 333 GB/hr
B. 450 550 GB/hr
C. 585 666 GB/hr
D. 1170 1332 GB/hr
A Symantec NetBackup customer is planning to add a second data center. They would like to leverage deduplication technology to improve backup operations and disaster recovery with a minimum amount of change to their existing backup environment. The customer's primary design goals are:
1.
Improve backup performance
2.
Electronic vaulting for disaster recovery
3.
Maintain NetBackup as their primary tool for backup control and visibility
What should be included with a high-end Data Domain appliance?
A. NetBackup OST
B. 8 GB Fibre Channel
C. iSCSI over 10 GB Ethernet
D. CIFS protocol over 10 GB Ethernet
A customer is interested in using a Remote Copy policy to replicate data between two single- engine EMC Disk Library (EDL) systems. The customer is concerned about the readiness of replicated tapes in case of a failure on the source system.
What can be done to minimize the exposure on the target?
A. Use small virtual tapes
B. Implement a TCP network accelerator
C. Use jumbo frames
D. Increase the number of EDL ports connected to the IP network
An EMC customer is evaluating a single-engine EMC Disk Library (EDL) system. They placed the EDL on their test infrastructure and performed 15 simultaneous backup jobs. The customer is concerned that the overall performance numbers are substantially lower than the published numbers.
Each job is sent to a separate virtual tape at an average rate of 18 MB/s. The EDL is connected to the SAN through two FC ports at 4 GB/s. There are a total of 15 LUNs for virtual tape storage. The infrastructure has been certified to sustain performance in excess of the EDL's capability.
What would you recommend to improve the overall performance?
A. Increase the number of simultaneous streams to at least 22
B. Disable Remote Copy
C. Increase the number of FC port connections to 4 and redistribute the tape drive assignment
D. Disable Capacity on Demand
A customer is interested in implementing two DL4000 systems. One system is located at a central site. The second is at a remote site as a target for Remote Copy operations. Policies will be configured to replicate certain tapes to the target.
Which process is necessary to make the virtual tapes available on the target?
A. Promote the replica resources to virtual tapes and move them into a VTL
B. Move the replicated virtual tapes from the virtual vault to a VTL
C. Remove the replication setting on the target virtual tapes to make them write enabled
D. Import the replicated virtual tapes on the target
A potential EMC customer has a T1 circuit between their production data center and their disaster recovery data center that are 2,000 miles apart. They currently back up their Linux systems to physical tape using HP Data Protector. They back up an average of 20 TB each night.
The customer wants a backup solution that improves backup and restore reliability, reduces overall costs, and eliminates physical tape. What is a recommended solution?
A. Data Domain with replication over IP
B. EMC Disk Library with Consolidated Media Management over FC
C. EMC Disk Library with Remote Copy over IP
D. Data Domain with OST and replication over IP
