A customer has implemented EMC Data Domain Boost for Oracle RMAN software in their environment and are successfully backing up several Oracle servers. Backups are directed to a local Data Domain system and a second Data Domain system was configured at their disaster recovery site as a target for replication.
What needs to be done to create copies of the backup data on the remote system that are tracked and recoverable by RMAN?

• A.Modify the RMAN script to include backup copies
• B.Configure directory replication between the Data Domain systems
• C.Create a second RMAN script for the second Data Domain system
• D.Configure Mtree replication between the Data Domain systems

If using NetWorker 7.6 SP2, what is the minimum number of Data Domain devices that should be configured to meet the requirement?

• A.6
• B.12
• C.10

An EMC Avamar customer is using Avamar SQL Server Client to back up their numerous MS SQL databases. They want to always make full backups for new databases and non- full backups for existing ones.
What are the recommended backup options to achieve this task?

• A.Force Full and Force Differential
• B.Full and Differential
• C.Force Full and Force Incremental
• D.Full and Incremental

An EMC Avamar customer has two remote sites; each site has an EMC Celerra. The local data center has an EMC VNX. The remote sites are on a different VLAN than the local data center.
Based on EMC best practice, how many NDMP Accelerator Nodes should be used and where should they be placed?

• A.3 - On the same VLAN as the Avamar server
• B.1 - Only in the local data center
• C.2 - One per VLAN located in the local data center
• D.3 - One at each remote office and one at the local data center

A client has a large ESX environment that they backup using EMC NetWorker. Their virtual machines are a mix of database and non-database servers. They currently perform guest- based backups so that their database server backups are application consistent.
They have asked you to address some performance issues they have been encountering.
Specifically, network utilization is high during backups. They would like you to provide a recommendation to reduce network traffic without adding additional cost while retaining application consistency.
What is a recommended solution that addresses the customer's issues?

• A.Switch the non-database servers to image-based backups and leave the database servers as is
• B.Provide additional bandwidth to the environment by installing additional network equipment
• C.Switch all guest backups to image-based backups to reduce backup traffic from the network
• D.Provide additional bandwidth to the environment by replacing slower equipment with faster equipment
