An Avamar customer has just deployed a VMware environment. The customer wants to ensure they receive the highest level of deduplication within the environment. Which type of backup should be performed?

The backup window of a customer using tape as a target for the current backup solution has increased over the allowed time. The customer needs to reduce the backup window by adding an intermediary process to a faster device before going to tape. What is that process?

A customer's environment currently has a backup window that exceeds the replication window. Which Data Domain characteristic will solve this issue?

In an EMC NetWorker backup environment, where do the metadata and backup policies reside?

You are backing up two different NAS servers, each with direct-attached tape drives. Backup Client X has 10 files of 100 MB each. Backup Client Y has 1,000 files of 1 MB each. What will happen under identical backup infrastructures?

On an Avamar server using default settings, what is the maximum allowable operating system capacity utilization after which HFS check will not run?

Due to a bottleneck on the LAN, a potential EMC customer is unable to meet their current SLA on backups. Which Avamar characteristic addresses the customer's issue?

If Data Domain is a target for backups, which environment will yield the highest deduplication compression ratio?

Where is most duplicate data on the Data Domain system discovered?

A customer is using EMC NetWorker to back up already compressed files to a device with compression enabled.
What is a possible impact?

A host has a file system with files changing every day. Full backups are performed every Sunday. The backup window during weekdays is limited. Full file system recovery should be accomplished in the shortest amount of time. Which type of backup should be performed every weekday to meet these requirements?

A customer is using NetWorker with a tape library to perform full backups at the end of the month and daily incrementals. The restore process takes a long time as tapes must unload and reload. The customer needs to achieve a faster recovery. What will help achieve the right RTO?

An Avamar administrator wants to run multiple backups from their Celerra through their single NDMP accelerator node. Based on EMC best practices, what is the recommended maximum number of backup jobs that the administrator can run at once, assuming there is enough RAM?

A customer has a critical 700 GB application that is CPU- and disk-intensive. The backup window for this application is one hour. Which backup method would you recommend for this application?

When does the Avamar server run garbage collection?

What is the RAID level on an Avamar NDMP accelerator node?

How is the communication between a Data Protection Advisor Collector and the Server performed?

What is the access mode of the EMC Avamar server during the garbage collect activity?

You are asked to propose a backup solution with the following requirements:
A Microsoft Volume Shadow Copy Service hardware provider is used to create a snapshot of production data.

✑ Rapid recovery of file systems and individual files from a snapshot.
Which EMC product would you recommend to support this environment?

Using the EMC Avamar sizing tool, you have determined that a customer requires four 2 TB data nodes. Since the customer is protecting only 5 TB of data, how is the additional storage used?

An EMC Disk Library customer is considering using Remote Copy between two engines. A policy will be configured to copy data when 50 MB of data is sent to the virtual tape. How does the data transfer occur?

Given an RPO, which factors must be considered when designing an EMC NetWorker backup solution?

A customer has two sites with 50 clients at each site. The customer wants the backup to occur locally on tape media at each site and would like to have a single
EMC NetWorker datazone for the entire environment. A NetWorker server has already been deployed at one site.
Which NetWorker component should be deployed at the second site?

A customer is planning to implement an EMC Disk Library with Active Engine Failover in their switched fabric environment. What is a requirement?

In an EMC NetWorker datazone, which component stores the online databases that track backups and volumes?
