An EMC customer is protecting 300 virtual machines (VMs) with guest level backup. All VMs reside on the same ESX server. The administrators are concerned with the CPU spike during backups since Avamar is trying to initiate as many backups as possible.
What is the best practice for preventing this spike in CPU on the ESX server host?
A. Use network throttling parameters in the advanced options of the dataset.
B. Reduce the connections per node limit on the Avamar server.
C. Schedule each virtual machine to begin backups one hour apart.
D. Migrate some of the VMs to another ESX host.
A VMware virtual machine has been performing guest level backups of the full file system to an Avamar server. However, the backup administrator decided to start performing image level backups of this virtual machine instead. The administrator notices that the first image level backup uses more capacity on the Avamar server than the guest level backup.
What is a possible reason for this behavior?
A. The virtual machine uses thick provisioning.
B. Changed Block Tracking is not enabled.
C. Snapshots are included in the backup.
D. System state data is included in the backup.
An EMC Avamar customer is performing image level backups of their VMware virtual machines, using a proxy. Why are the backups not working?
A. The Data Store is not assigned to the proxy client.
B. The backup is already using six streams.
C. The proxy cannot assign the hash cache.
D. The backup client is not installed on the VM.
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 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.
A customer needs to exclude certain VNX sub-volumes in their Avamar NDMP backup environment. What should you tell the customer?
A. Excludes are not supported in Avamar for VNX.
B. Exclude sub-volumes on the VNX.
C. Exclude sub-volumes in the dataset options.
D. Use includes instead of excludes.
A customer has an EMC VNX and a NetApp filer that they are using to provide network shares to their employees. The content on these devices is being protected by an EMC Avamar 7.0 with one accelerator node. The backup data is stored
on an integrated Data Domain running 5.3.
They are planning to consolidate their mixed environment by replacing the VNX and NetApp filers with two EMC Isilon systems.
What other changes must be made to support the new configuration?
A. Backup data will have to be stored on the Avamar server.
B. A second accelerator node will have to be configured.
C. The accelerator node will need to be configured for dual NIC operation.
D. The Data Domain OS must be upgraded to 5.4.
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 database administrator added a DB2 database that is being backed up online through the Avamar DB2 plug-in. They have been instructed to shorten the backup time of the database due to the Avamar backup window being quite full when the backup takes place. To accomplish this, they have excluded the archive logs from the dataset.
What else must the administrator do to ensure that no data loss occurs in the event they need to restore the database?
A. Include the archive logs in the file system backup.
B. Back up the archive logs separately using the DB2 plug-in.
C. Perform an offline backup of the database.
D. Perform an offline backup of the archive logs using the DB2 plug-in.
A database administrator wants to perform a restore from an online backup of their DB2 database that was taken the previous day via DB2 CLP. Upon looking at the backups from the previous day in Avamar Administrator, they notice multiple backup names are present.
Which backup should they choose?
A. CLI-H-DB2 Database(s) backup
B. GUI-H-DB2 Database(s) backup
C. CLI-C-DB2 Database(s) backup
D. GUI-C-DB2 Database(s) backup
