While designing an EMC Data Domain solution for a customer, you want to determine the amount of storage capacity needed. You have discovered the following information:
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 burn rate (in GB)?
A. 150
B. 160
C. 175
D. 200
A customer wants an EMC Avamar solution that provides 8 TB of deduplicated data protection. In addition, they need to protect a VNX system and export data to tape. They anticipate data growth of another 6 TB in the next year.
Which Avamar components should be used to architect the solution, in as few nodes as possible, while meeting sizing best practices?
A. Avamar multi-node server, and an NDMP Accelerator and Media Access nodes
B. NetWorker deduplication server and tape export, and an NDMP Accelerator node
C. vamar integrated with Data Domain and a Data Domain VTL license
D. Avamar Business Edition server, and an NDMP Accelerator and Media Access nodes
An existing EMC NetWorker customer is planning to integrate EMC Data Domain systems into their backup infrastructure. They would like to:
Backup their Microsoft Windows client data using CIFS to a Data Domain system Take weekly Data Domain system snapshots of Windows client backup data Backup their Linux client data using NFS to a Data Domain system Take daily Data Domain system snapshots of Linux client backup data Based on EMC best practice, what should be considered when designing the Data Domain file system layout?
A. Create a separate MTree for CIFS and NFS client data
B. Create an MTree named "data" and create separate sub-directories for CIFS and NFS client data
C. Under /backup MTree, create separate sub-directories for CIFS and NFS client data
D. Create separate storage units for CIFS and NFS client data
A customer has two data centers and each data center has an identical EMC Data Domain system. The customer needs a replication strategy that meets the following objectives:
User name and passwords are unique /data/col1/backup are identical Data Domain destination directory is read only Ownership and permissions remain identical
Which type of Data Domain replication should be configured?
A. Directory
B. Collection
C. MTree
D. Pool
A customer would like assistance with the design of an EMC Data Domain environment. Based on best practices, what should the customer know about Data Domain MTrees?
A. Supports a maximum of 14 simultaneously active MTrees Pre-configured for NFS export /backup Supports compression
B. Supports a maximum of 100 simultaneously active MTrees Pre-configured for NFS export /backup Implements data integrity
C. Supports a maximum of 14 MTrees Pre-configured for CIFS export \backup Implements data integrity
D. Supports a maximum of 100 MTrees Pre-configured for CIFS export \backup Supports compression
While designing an EMC Data Domain solution, you 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
You are sizing an EMC Data Domain system for a new customer. The customer has provided their capacity and performance requirements for the system.
When selecting a Data Domain model to meet their requirements, according to best practices, which buffer
size should be used?
A. 5% - 10%
B. 10% - 15%
C. 15% - 25%
D. 20% - 30%
In an EMC Data Domain environment, what is a supported Extended Retention replication configuration?
A. Collection replication from the active tier to the Retention Unit
B. MTree replication directly to the Retention Unit on the target
C. Collection replication from the GDA to the Retention Unit
D. Directory replication from the GDA to the Retention Unit
A customer wants to use EMC Data Protection Advisor (DPA) to report on their NetWorker backup environment. The customer requires that no additional software be installed on the NetWorker server.
What is minimum NetWorker software requirement when collecting NetWorker data using a DPA proxy?
A. NetWorker client is required on the proxy agent
B. NetWorker storage node is required on the DPA application server
C. NetWorker server is required on the proxy agent
D. NetWorker storage node is required on the proxy agent
A new EMC Data Domain customer has a requirement to store the maximum amount of backup data on their Data Domain system. They are deciding on the type of local compression to use for their backups. When planning the Data Domain design, what should the customer know about the compression types?
A. gz compression uses the least amount of space and the most CPU cycles
B. gzfast compression uses less space and twice as much CPU cycles as gz
C. gz compression uses 30% to 40% less storage space on average than lz
D. lz compression uses the least amount of space and the most CPU cycles
