An EMC NetWorker customer wants to add their new Microsoft SharePoint distributed farm to their backup environment. The farm contains three servers. One server contains the web front-end and the other two servers each contain two SQL databases.
How is the number of the client resources determined?

You are planning an MS SQL backup solution for a customer using EMC NetWorker and NMM without a proxy client. Which user privilege must be configured on
NetWorker?

An EMC customer is currently backing up their Microsoft Exchange database to an EMC Avamar server. The backups are setup to full on Friday, skip on Sunday, and only transaction logs backed up the rest of the week. The customer would like to integrate Data Domain to Avamar and run the database backups to the Data
Domain system.
If a Data Domain system is deployed on Sunday, which type of backup runs on the following Monday?

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 customer has an EMC Data Domain appliance that has reached 90% of maximum capacity. The customer does not want to purchase any additional storage.
What will increase the average available capacity of the Data Domain appliance?

An EMC NetWorker customer has just started running backups of their new Microsoft SharePoint distributed farm. They are concerned that their web applications are not being backed up.
What can you tell the customer about backing up web applications?

An existing EMC Data Domain customer wants to know the way to integrate Data Domain with RMAN to their tape library. How would this integration take place?

An EMC NetWorker customer has an 8 TB Oracle database. They want to know the most efficient way to backup with NetWorker to Data Domain deduplication.
When integrating NetWorker with Data Domain, what is an Oracle best practice?

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?

An EMC NetWorker customer has a corporate requirement for secondary offsite backup to meet governmental regulations. What is the NetWorker disaster recovery best practice for client backups performed on a NetWorker deduplication node?

A customer noticed that they have incorrectly configured their NetWorker Browse and Retention policies for all currently defined clients. This issue was discovered when a DPA report was e-mailed showing the amount of available space on their EMC Data Domain system.
The customer has made the necessary corrections to the Browse and Retention policies. They have manually deleted save sets that should have been expired based upon the new Browse and Retention times. After comparing the size of the index directory, prior to and after the modification, the customer noticed that the index directory decreased in size by several hundred GB. However, the available space on the Data Domain remained unchanged.
Although NetWorker has deleted the necessary indexes, why does the Data Domain available capacity remain the same?

You have been tasked with designing a backup solution using EMC NetWorker to backup a VMware environment. The environment will be using virtual NetWorker proxies to perform image-based backups. You will need to backup 36 virtual disks at a time in order to meet the backup window. The ESX hosts used in this environment are low-end and have a small amount of processing power.
What is the recommended way to configure NetWorker proxies to meet this design?

An EMC Avamar customer regularly backs up their SharePoint distributed farm. They noticed that with the backup taken today, Avamar has listed the backup under a different farm name.
What is a possible cause?

You are creating a backup solution for a VMware environment and will be using snapshot technology. You want to ensure that your solution follows best practices.
What is a consideration when designing this solution?

A customer with a full virtualized environment is protecting their virtual machines (VMs) with EMC NetWorker with VADP proxy host. Even though all the VMs are
Microsoft Windows based OS with NTFS, it is not possible to browse the file for recovery.
What is the reason for this issue?

A customer is configuring Oracle servers in their environment for the first time. They would like to use their existing EMC Avamar server to protect these new systems. They have asked you to explain the various point-in-time recovery modes.
When using the System Change Number recovery mode, how often is the System Change Number updated in Oracle?

An Oracle customer has configured backups of five Oracle servers to their EMC NetWorker server. Over the past month they have been successfully performing hot backups using the NMDA module. Now, one of the databases has become corrupted and they would like to perform a point-in-time recovery of the database.
Which option needs to be included in their RMAN script to perform this action?

A customer has an EMC VNX series NAS and two Oracle database servers with 25 TB of data on each database. The customer is considering an Avamar/Data
Domain backup solution.
What is the most efficient solution for this environment?

Click on the calculator icon in the upper left corner.
An EMC NetWorker customer is sizing a NetWorker storage node to backup to their newly purchased Data Domain system. The customer is projecting that a minimum of eight datastreams and a maximum of 40 datastreams will be sent to the Data Domain system.
Based on EMC best practice, at a minimum, how much memory should be available for the storage node?

An EMC customer has a 10 TB Avamar system with two 10 TB integrated Data Domain systems. The customer is building a disaster recovery (DR) data center and would like to replicate all backups to the DR site.
Which setup would meet the requirements for data replication?

A customer has an EMC NetWorker and Avamar integrated datazone. The datazone consists of an Avamar server, an Avamar replication server, and a single
NetWorker server. Backups, restores, and replication have been successful. The customer noticed that expired savesets are not being deleted from the Avamar replication server.
What would prevent the savesets from being removed from the Avamar system?

A customer has an EMC Celerra with one NFS share that contains five million files. The backup administrator is backing up the entire NAS using EMC NetWorker to a Linux storage node utilizing NDMP. The administrator is noticing that the restore performance is poor despite the good backup speed.
Based on the given situation, what can be done to address the poor restore performance?

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?
