EMC E20-329 Exam Questions & Answers

Refer to Scenario .

A customer is looking to modernize their backup infrastructure. The current environment consists of a

single centralized data center and several remote sites. The centralized data center hosts all core services

and applications. The remote office primarily consists of sales personnel with 4000 use-North America,

500 in Europe, and 300 in Asia using file servers.

The current backup environment at the primary site uses CommVault backing up to a Fibre Channel tape

library that contains four ITO-4 tape drives. Currently they are backing up a number of file servers as well

as several databases that have average change rates of 7% daily Remote office backups are currently

performed by having users copy files to regional file servers that are then backed up to tape.

In the past few months, the customer has expenenced problems with getting backups to finish within their

defined windows as well as issues with the tape library hardware. They now have concerns about gaps in

their backup coverage as well as the reliability of the tape media. In addition, an internal audit shows a

large amount of user-generated data is unprotected on remote user laptops.

The customer is looking for a common platform to standardize their backups. They want a solution which

allows for a centralized infrastructure so -they do not need to rely on remote resources to address

hardware and software issues. The other goal is to move away from tape to a more reliable disk-based

solution.

The customer is interested in Avamar to backup all their worldwide remote users. Based on best practices, which EMC solution will satisfy the customer's requirements?

A. Deploy a single Avamar system at the primary location to back up all clients

B. Deploy Avamar systems into each major geographical location, including Asia, Europe, and North America

C. Deploy Avamar single-node systems at the remote sites and an Avamar system at the primary location as a replication target

D. Deploy three Avamar grids to the primary location, each grid will be dedicated to a specific region

An EMC Avamar customer is running a backup that is being directed to a Data Domain system. Although the backup completed successfully, the customer decides to delete the backup.

When does data, from expired backups, move from /cur to /DELETED?

A. Next time the Avamar system runs garbage collection

B. Immediately after expiration on the Avamar system

C. Manually deleted on the Data Domain system by the administrator

D. Next time the Data Domain file system cleaning operation runs

You are having a preliminary discussion with a prospective customer. The customer would like to know the deduplication rates that are typically seen when running initial EMC Avamar backups for file system and database data.

Which information should be provided to the customer?

A. File system = 20%; database = 80%

B. File system = 50%; database = 50%

C. File system = 70%; database = 35%

D. File system = 80%; database = 20%
