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

A new EMC Avamar customer would like to configure backups of a single SQL instance running on a two-node Microsoft SQL cluster. To enable backups of the SQL database, what is the order of installation for the client software?

• A.Install Avamar Windows client on both nodes.
  Install the Avamar SQL client on the active node in the cluster.
• B.Install the Avamar Windows client and Avamar SQL client on both nodes in the cluster.
  Configure the Avamar Cluster Client on both nodes in the cluster.
• C.Install the Avamar Windows client and Avamar SQL client on both nodes in the cluster.
  Create AvamarBackupUser and configure the Avamar Cluster Client on both nodes in the cluster.
• D.Install the Avamar Windows client and Avamar SQL client on both nodes in the cluster.
  Configure the Avamar Cluster Client on the active node in the cluster.

An EMC NetWorker customer wants to replicate backup data stored on their Data Domain system to a new, offsite Data Domain system. They want the benefits of replicating data in deduplicated format. However, they also want to be able to manage and report on the replicated save sets using NetWorker media database information.
To meet their requirements, which method of storing backup data on the Data Domain system and which type of replication should be used?

• A.DD Boost for the backup data and clone-controlled replication
• B.DD Boost for the backup data and regular clone operation
• C.AFTD for the backup data and regular clone operation
• D.AFTD for the backup data and clone-controlled replication

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 goalsare:
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.CIFS protocol over 10 GB Ethernet
• C.8 GB Fibre Channel
• D.iSCSI over 10 GB Ethernet

You are designing an EMC NetWorker to Data Domain backup solution for a customer using DD Boost. The customer plans to configure an old server to use as a storage node.
Which factor, in the backup environment, affects the amount of memory that this server should have for optimal backup performance?

• A.Number of backup clients
• B.Size of the Data Domain system
• C.Number of simultaneous save streams
• D.Amount of backup data
