A customer is using EMC Avamar to perform image-based backups of a VMware virtual machine (VM). Since the VM has a large amount of data, the backups are taking a long time. The customer decides to enable Changed Block Tracking (CBT). However, the backups are now taking even longer to complete.
What is a possible reason?
A. The VM is experiencing a very high change rate.
B. First few CBT backups will often take longer than normal.
C. The VM's virtual disks are mounted by multiple VMs.
D. The proxy server has not been configured for CBT.
A customer has been performing VMware image level backups of a Linux virtual machine (VM) to their Avamar server. They find that they are unable to restore a file from the image backup. What is a possible cause of this issue?
A. The Linux VM uses an Ext4 file system.
B. Linux file level restores are not supported.
C. No proxy server is enabled for file level restore.
D. Avamar Agent is not running on the VM.
A backup administrator wants to create file system consistent backups of eligible VMs when backing up their VMware environment via the VADP interface. Which types of VMs are eligible?
A. Windows VMs with VSS support and VMware Tools installed
B. Linux and Windows VMs with VMware Tools installed
C. Linux VMs with VSS support
D. Windows VMs with VMware Tools installed
A backup administrator in a large VMware farm noticed that backups are no longer completing within the backup window. The VMware team is concerned about adding more proxies. What is a potential solution to this problem?
A. Increase CPU resources assigned to the existing proxies from their defaults.
B. Increase the number of concurrent backups per proxy from 8 to 10.
C. Increase the cache file sizes on the existing proxies.
D. Add an AVE that can share the existing proxies and vCenter.
A business is currently using a tape backup solution with third-party backup software and doing the off-siting for Disaster Recovery. In an effort to minimize the costs for managing IT they would like to use tapeless backups and virtualize their environment.
They have the following, additional requirements:
-Introduce data deduplication for their backup
-Protect their database servers running on VMs
-Achieve highest level of deduplication
-
File level restores for all the virtual machines What should you advise the customer to deploy?
A.
Avamar with Guest Level backups
B.
Avamar with Image Level backups without CBT
C.
Avamar with Image Level backups and CBT
D.
NetWorker with Avamar deduplication node
An EMC customer wants to implement a backup solution for their virtual machines. They are interested in Avamar deduplication features. In addition, they want to minimize the backup capacity required. Their ESX environment is running optimally with sufficient resources.
Which backup method will provide the most optimized capacity?
A. Guest level
B. Instant Access
C. Image level with CBT D. Image level without CBT
An EMC customer has Windows virtual machines running in a VMware vSphere environment protected by an Avamar multi-node server using guest level backups. They are concerned with the RTO of these virtual machines. Which method would provide the lowest RTO?
A. Deploy a template of the OS that is preinstalled with the Avamar agent and restore selected data.
B. Capture VSS backups of the server and boot from the recovery ISO to restore the server.
C. Use an Avamar VMware Image Proxy and restore the VM with CBT enabled.
D. Use an Avamar VMware Image Proxy to perform file level restores.
A new VMware virtual machine has been created and will be protected with Avamar guest level backup. In addition, image level backups are not able to be performed in this environment. What can be done to provide quick, full system restores with an RPO of one day while keeping backup times low?
A. Create a VM template and perform daily backups of unique data.
B. Perform backups of the full file system every day.
C. Perform daily CBT backups from the guest machine.
D. Perform daily system state backups.
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 provisioned 2 TB of virtual disks using VMAX thick provisioning with RAID 5 protection and zeroed out all blocks using eager zeroing. They 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 RAID 10 for the virtual devices.
B. Use ESX 5.0i to host the AVE server.
C. Use thin devices for the virtual devices.
D. Use lazy zeroing to zero out all blocks.
A customer has a NAS device that is performing NDMP backups to an Avamar 7.0 server. They have recently added more capacity to their NAS device and have noticed that backups are taking significantly longer to complete. They ask you if they should consider tuning the file cache. How should you respond?
A. NDMP backups to Avamar do not use a file cache during the backup process.
B. Demand paging caches for NDMP backups are self tuning and do not need adjustment.
C. The file cache size may be increased if the NDMP accelerator has 8 GB of RAM or more.
D. The file cache on the NAS device may be tuned to accommodate more files.
