QUESTION NO: 3
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?

QUESTION NO: 4
A customer's SharePoint environment consists of:
- 3 Web front end (WFE) servers
- 2 Application servers
- 1 Configuration database server
- 2 Content database servers
The customer installed it according to EMC best practices for a Federated SharePoint environment by installing software on one of the three WFE servers and all of the other servers.
The WFE with the client installed fails just prior to the beginning of the backup. The customer decides to install the client software on a second WFE and perform the backup via the alternate WFE.
What is the result?

QUESTION NO: 5
A customer has four EMC Avamar servers located in a centralized disaster recovery site, each receiving replicated data from several remote sites. Several client backups are in the range of 1 - 4 TBs per dataset with file counts of 2 - 4 million files. Due to capacity limitations, Avamar retention value is limited to two months and tapeout is being used to provide extended retention of up to five years.
The nature of the customer's business requires frequent lookups of historical data, often beyond the Avamar
2-month retention period. Therefore, quick recovery of files from tape is required. Compliance requirements mandate tapeout be performed on a weekly basis. The customer is considering Avamar Data Transport (ADT) or Avamar Tape Out (ATO).
Which tapeout solution is best suited for this environment?

QUESTION NO: 6
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 Dell EMC Avamar 7.4.1 administrator is testing the file level restore feature from VMware image backups.
They restore a large number of files to VM1, then restore the same files to VM2. Both restores succeed, but the restore for VM2 is much slower.
What is a possible reason for the slower restore performance?

A customer is adding a new IBM DB2 client to their existing EMC Avamar server environment. They have ensured that they have root privileges on the system and DB2 is up and running properly on the AIX 5.3 server. In addition, they have installed the AIX Avamar client and can ping the Avamar server by hostname from the DB2 server.
The installation of the DB2 Avamar client plug-in is failing but passes an MD5sum check. What is the probable cause of the failure?

A backup administrator notices that one of their client backups fails after two consecutive successful backups.
They investigate the avagent.log file and find that the client attempted to connect with the data nodes, but failed. The administrator verifies that all required firewall ports are open and resource performance is not experiencing a bottleneck.
Which file should the administrator investigate?

QUESTION NO: 15
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?
