EMC E20-329 Online Questions & Answers

  • Question 311:

    An EMC NetWorker customer is performing all backups to physical tape. This includes weekly 10 TB backups of static medical imaging data stored on a Dell NAS requiring 8 months retention. Their current tape libraries are approaching end of support life.

    The customer has asked EMC for a recommendation that will improve operational backup and restore reliability for their image data with a minimum amount of change. What will meet the customer's requirements?

    A. EMC Disk Library
    B. Deduplication Node
    C. Avamar
    D. Data Domain

  • Question 312:

    A customer is planning a new database rollout using Oracle and wants to perform online backups. Initial tests with NetWorker have shown that the backups cannot be completed within the backup window of 6 hours.

    You have analyzed your backup environment and there are adequate resources to meet this stringent backup window. What is one of the first things to check in NetWorker or RMAN to increase performance without adding cost and complexity?

    A. Adjust the maximum number of files in a backup set to be less than the number of open files
    B. Adjust RMAN channels to have multiple streams per tape device
    C. Adjust RMAN multiplexing to be less than the tape multiplexing setting
    D. Adjust RMAN multiplexing to be equal to or greater than the tape multiplexing setting

  • Question 313:

    Scenario

    A customer is looking to perform a data center refresh. They want to standardize their backup infrastructure by using EMC NetWorker, Avamar, and Data Domain in an integrated environment. The environment consists of:

    A primary data center - NetWorker server, Data Domain, and Avamar A disaster recovery (DR) data center - Data Domain only 220 remote sites Each remote site consists of approximately 30 clients and 1 storage node LAN speed at and

    between all sites is 1 Gb

    The company's Chief Technology Officer (CTO) has indicated that data must be backed up locally. Then, the data must be copied offsite to the primary data center and DR data center. The entire solution must be managed from a single

    unified interface in order to configure and track backup jobs.

    The company is subject to government regulations concerning data retention policies for confidential data. Data has to be retained for seven years on tape at the DR data center.

    Assume each remote site has 30 clients, three devices per remote storage node, and NetWorker Power Edition are used. At a minimum, how many datazones will be needed?

    A. 1
    B. 2
    C. 3
    D. 4

  • Question 314:

    A customer requires support for 60 MTrees on a single Data Domain System. At most, 50% of the MTrees will be active at the same time. Which Data Domain system fulfills the customer's requirements?

    A. DD7200
    B. DD2500
    C. DD870
    D. DD160

  • Question 315:

    An EMC Data Domain customer has ordered two expansion shelves to increase the active tier storage capacity for backup. After successfully installing the new expansion shelves, the Data Domain GUI does not display the increased capacity.

    What is the reason for this issue?

    A. Shelf Capacity licenses were not installed
    B. Disk drives need to be reconfigured
    C. Expansion Storage license was not installed
    D. Active tier and Archive tier licenses are needed

  • Question 316:

    Which features will have a negative impact on the performance of an EMC Data Domain system?

    A. Cleaning, gz Compression, 25 MTrees, and encryption
    B. Network collisions, replication, cleaning, and encryption
    C. Encryption, replication, cleaning, and Mtrees
    D. Global deduplication, replication, DD Boost, and 25 Mtrees

  • Question 317:

    You are adding an Avamar deduplication node to a customer's EMC NetWorker environment. Clients currently back up to tape and perform full backups on Sunday and incrementals on all other days. In the new solution, these clients will back up to the deduplication node. The speed of recovery is important to the customer. Which changes may be required to the backup schedule?

    A. Perform Full on Sunday and Level 1 backups on all other days of each week
    B. No changes are required to the backup schedule
    C. Perform initial Full backup and Level 1 backups forever
    D. Perform Full backups every day

  • Question 318:

    A customer has a multi-node EMC Avamar server with eight active storage nodes. They are currently at 85% GSAN capacity and receiving capacity warning messages. The customer would like to purchase four additional nodes for the system.

    What is a best practice for adding capacity?

    A. Add two nodes at a time to the existing server
    B. Add one node at a time to the existing server
    C. Migrate capacity to a different server if available
    D. Acquire a new server with sufficient capacity

  • Question 319:

    In an EMC NetWorker environment, a firewall is configured to allow communication over ports 9000 and 9001 from the DMZ. The NetWorker Management Console can be accessed from the DMZ but database queries cannot be performed. Which port needs to be opened on the firewall?

    A. 111
    B. 2638
    C. 7937
    D. 7938

  • Question 320:

    A customer has an EMC Data Domain appliance that has reached 90% of maximum capacity. The customer does not want to purchase any additional storage. What will increase the average available capacity of the Data Domain appliance?

    A. Decrease the backup retention period
    B. Decrease the cleaning frequency
    C. Increase the snapshot expiration period
    D. Increase the number of streams
