You are having a conversation with an EMC Avamar customer regarding the final design. They indicate that they have certain data that needs to be carefully secured during transit. This data is typically transferred at different times and in different groups.
Which type of encryption would address the customer's concern?
A. AES-256 encryption set at the time of the backup operation
B. AES-128 encryption set at the time of server installation
C. Blowfish encryption enabled at the group policy level
D. AES-256 encryption automatically enabled for all backups
A customer requires support for 60 MTrees on a single Data Domain System. At most, 50% of the MTrees will be active at the same time.
Which Data Domain system fulfills the customer's requirements?
A. DD7200
B. DD2500
C. DD870
D. DD160
A customer's Data Domain DD2500 system has 32 active MTrees. They notice performance issues when using the configuration.
What is the minimum number of MTrees that should be removed from active use to improve performance?
A. 14
B. 16
C. 18
D. 20
A customer wants to know why their backup performance to an EMC Avamar multi-node server has decreased. Initially they were seeing an ingest rate of approximately 5 to 7 GB/hr/node. Recently they estimated that the ingest rate has slowed to around 3 to 5 GB/hr/node.
What is a probable cause for the decrease in the average ingest rate?
A. Stripes contain more data, and steady state has been achieved.
B. HFS check has found errors and has not been completing successfully.
C. A large number of backups have expired, causing new stripes to be created.
D. Garbage collection is not running, causing new stripes to be created.
Which set of features would have a negative impact on the performance of an EMC Data Domain system?
A. Cleaning, 'gz' compression, 35 active MTrees, and encryption
B. Network aggregation, replication, cleaning, and encryption
C. Encryption, replication, cleaning, and local compression disabled
D. Global deduplication, replication, DD Boost, and 5 active MTrees
Your customer is looking for a new EMC Data Domain backup solution. They require a solution that provides the ability to operate at no more than 75-85% of its rated capacity. In addition, 1.2 TB per hour throughput is required.
What should be considered when selecting a Data Domain system to meet the performance requirements?
A. Max Throughput and Max Capacity
B. Max Throughput and Amount of Data
C. Number of Clients and Amount of Data
D. Max Capacity and Amount of Data
An existing EMC Data Domain customer currently has one Data Domain system at their headquarters (HQ) data center. They would like to mirror all data from the HQ Data Domain system to a Data Domain system at their disaster recovery site using collection replication.
When proposing a solution, what should the customer be told about collection replication?
A. Username and passwords are replicated from the source system.
B. Logs and messages are replicated from the source system.
C. Performance statistics are replicated from the source system.
D. Bi-directional collection replication can be set up between the two systems.
A customer has a requirement to size active tier storage beyond the entry capacity of their Data Domain controller.
Which license will meet the customer's requirements?
A. Shelf Capacity
B. Extended Retention
C. Gateway Expanded Storage Level 2
D. Gateway Expanded Storage Level 3
You are designing an EMC Data Domain solution and need to determine the required amount of storage capacity. The following information was gathered from the customer: 2 TB full backup @ 5x compression 10% daily data change rate 4 incremental/week @ 10x compression 1x full per week @ 25x compression Retention period = 4 weeks with no data growth
What is the minimum amount of storage needed to support this solution?
A. 850 GB
B. 900 GB
C. 1040 GB
D. 1200 GB
A customer has recently purchased EMC Data Protection Advisor (DPA) for backups to monitor their NetWorker backup environment. They are currently monitoring the NetWorker servers and storage nodes.
What else can be monitored without the need for additional DPA licenses?
A. Physical and virtual tape libraries
B. VMware server status
C. Replication technologies
D. VMware configuration data
