A new EMC Avamar customer wants help in setting up their backup groups and schedules. They are migrating from a traditional tape backup solution with full backups performed once a week and incrementals in between. They have a regulatory requirement to keep an annual backup for seven years but want to keep all other backups for one month. Both Microsoft Windows and Linux clients will be backed up. Based on best practices, what should be recommended?

A. Include all clients in the same group using one dataset and an advanced retention policy

B. Use a separate group for each operating system /retention combination

C. Enable the default group and use that group for all backups

D. Use one group for weekly backups and one for the other days of the week

A customer has a EMC Avamar desktop/laptop environment consisting of 100 clients distributed across three Avamar domains. Compliance requirements mandate that 15 clients with 2 TBs of data on each must have their backups written to

tape. Avamar Data Transport (ADT) with three 2 TB transport nodes will be used to accomplish the tapeout process.

Which changes are required to accommodate this environment?

A. Configure each of the clients in their own dedicated domain

B. Configure a dedicated transport node per Avamar domain

C. Configure a dedicated transport node, each containing five of the clients

D. Configure three domains, each containing five of the clients

Refer to Scenario 9.

Where would the data be referenced in the GSAN?

A. /Oracle/avamar161.lss.emc.com

B. /avamar220.lss.emc.com

C. /Clients domain

D. controlfile

An Oracle 10g database is being backed up to an Avamar server.

Which statements about the Oracle backup and restore process are valid?

B. Oracle RMAN performs backup through avoracleavagent generates the RMAN script RMAN creates its own log file

C. Oracle RMAN performs backup through avagentavtar generates the RMAN script Avamar client agent runs RMAN

D. Oracle RMAN performs backup through avtaravagent generates the RMAN script Avamar client agent runs RMAN

A customer set up their Dell EMC VNX to back up through a Dell EMC Avamar NDMP Accelerator node. They are not seeing any increased performance since the initial backup. In addition, they have investigated the VNX and there are no outstanding issues.

What is a potential reason for the poor backup performance?

A. Dataset options are set to Level 0.

B. The dataset advanced option is blank.

C. Data has a low change rate.

D. File cache is using demand-paging.

A customer has an EMC Avamar system backing up a Celerra running DART 6.0 using a single 36 GB NDMP accelerator node. They are also going to back up a VNX OE 7.0 system using the same NDMP accelerator node.

Each NAS device has 6 GB RAM and four volumes configured on it. Backups will be configured on the Avamar system for both NAS storage devices to start at the same time.

What will occur when the NDMP backups start using default settings?

A. One NAS device will start its backup with four streams; the other will queue.

B. Both backups will start, each with two active streams.

C. One NAS device will start its backup with one stream; the other will queue.

D. Both backups will start, each with one stream.

An EMC customer is looking for options to back up their smaller remote sites with easy remote management, so they want to use Avamar Virtual Edition (AVE).

Before installing ESX hardware at the remote sites they want to do a proof of concept using the existing ESX 4.1 server that they have at the data center. They have provisioned 2 TB of virtual disks using VMAX thin provisioning with RAID 1

data devices. They have tested the backup of three servers and do not see an improvement.

According to best practices, what should the customer have done to avoid performance issues?

A. Use thick devices for the virtual devices.

B. Use ESX 5.0i to host the AVE server.

C. Use RAID 10 for the virtual devices.

D. Use lazy zeroing to zero out all blocks.

A backup administrator has created a Dell EMC Avamar rule to match certain VMware VMs. After they use the rule for auto-discovery they notice that the rule accidentally activated a large number of test VMs. They modified the rule to Exclude the test VMs but they are still activated.

What should they do to remove the test VMs?

A. Run auto-discovery again

B. Sync with the vCenter server

C. Delete the rule and create a new one

D. Delete the test VMs manually

A backup administrator is looking for advice on how to achieve a steady state condition for their multi-node Dell EMC Avamar server with five storage nodes. What is the approximate amount of storage that garbage collection should free up at steady state?

A. 5 GB per hour for the Avamar server

B. 10 GB per node per hour

C. 15 GB per hour for the Avamar server

D. 20 GB per node per hour

A backup administrator is running image backups of a Windows 2012 VM on a clustered Hyper-V server. They notice that the backups are crash consistent, not application consistent.

What is a potential reason for this issue?

A. Virtual machine is in a powered-off condition

B. Dataset is not configured for application consistency

C. Dell EMC Avamar Hyper-V plug-in installed on the VM

D. Backup is running from the passive cluster node
