An EMC NetWorker customer has an Oracle database client. To achieve acceptable backup performance, they have configured the backup to use four RMAN channels.
The customer wants to benefit from adding Avamar deduplication for this backup. What is a consideration
before proposing this design change?
A. Data from each RMAN channel must be sent to a separate deduplication node
B. Less than six RMAN channels in a deduplicated backup will perform poorly
C. More than two RMAN channels in a deduplicated backup will cause the backup to fail
D. Separate cache files are recommended for each RMAN channel
You are designing a backup solution for an EMC NetWorker customer. Based on EMC best practices, how many CPU cycles are needed by the storage node when backing up clients over the network to local tape drives at a rate of 100 MB/s?
A. 0.2 Hz
B. 0.5 Hz
C. 1.2 GHz
D. 2.4 GHz
A customer plans to integrate an EMC Disk Library (EDL) with NetWorker. The customer has purchased an Embedded Storage Node License to clone virtual taped from the EDL to a physical tape library. What should be included in the design document design to ensure the Embedded Storage Node reads the data from virtual tape during a clone operation?
A. VTL Auto-changer resource needs the Embed Storage Node defined as the Read Host Name
B. Client resource of the Embedded Storage Node needs the Embedded Storage Node defined as the Clone Storage Node
C. Client resource of the NetWorker server needs the Embedded Storage Node defined as the Clone Storage Node
D. Each backup client resource needs the Embedded Storage Node defined as the Clone Storage Node
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
When sizing an EMC Avamar or Data Domain solution, what are important challenges that should be taken into consideration?
A. Data types, change rate, and growth rate
B. Hardware type, change rate, and backup policy
C. Data frequency type, and backup and restore policies
D. Industry growth rate and deduplication ratio
Refer to Scenario.
An enterprise customer would like to better address business continuity at all branch offices. Their
corporate data center resides in Chicago, Illinois and they would like all branch office data centers to use
Chicago as the destination for replicating backups.
Each branch office has a mixture of databases, e-mail, and other data that need full backups on Friday
evenings and daily incremental backups. Based on their new Chief Technology Officer's experience with
deduplication, they are installing EMC Data Domain devices at all sites to take advantage of the lower
bandwidth requirements for backup replications.
The backup requirements for the branch offices are:
1.
New York, Denver, and Houston = 100 GB full, 20% daily incremental
2.
SCO, Seattle, and Kansas City = 20 GB full, 20% dairy incremental
The San Francisco branch office has an existing VTL infrastructure. Which type of replication is recommended for their backups?
A. Collection
B. Pool
C. Directory
D. MTree
A customer has informed you that they would like to purchase an EMC Avamar solution. They plan to implement enhanced security by encrypting all backup data that is stored on the Avamar server. During the final sizing of this solution, what should be taken into consideration?
A. System resources may be impacted by as much as 33%
B. System capacity may be increased by a maximum of 5%
C. Server performance will decrease by 43%
D. Backup windows should be modified by 10%
A customer is currently using EMC Data Protection Advisor (DPA) 5.8 and would like to begin using DPA
6.0. What is the next activity that must occur?
A. Perform a migration rather than an upgrade
B. Use the DPA 6.0 Installer to upgrade in-place
C. Uninstall DPA 5.8 and then install DPA 6.0
D. Use the DPA migration tool to perform the upgrade
A customer has data at several remote offices that needs to be backed up over a secure WAN connection to their data center. However, bandwidth is constrained. A major portion of their backup data will be file system data. In addition, they have a 6 TB database in the primary data center with a 6% change rate that needs to be backed up.
Which EMC backup solution is recommended for this customer?
A. NetWorker with Avamar integration
B. NetWorker with Data Domain and CIFS
C. NetWorker with Data Domain and DD Boost
D. Avamar server with Avamar Virtual Edition
You are asked to design an EMC NetWorker backup solution for a large Microsoft Exchange 2010 DAG environment. Their backup requirements are: Leverage Microsoft VSS to create consistent snapshots of Exchange mailbox database Keep the last two snapshots on the disk array for instant recovery Use NetWorker to schedule and manage the snapshots and roll the last snapshot over to a Data Domain system
What is a design consideration?
A. Exchange mailbox database and transaction logs need to be backed up at the same time
B. Using NetWorker wizard to create client resources for all Exchange 2010 DAG members
C. NetWorker save set should be set to 'All' to back up all Exchange 2010 DAG members
D. Using an EMC VSS hardware provider for the rollover operation
