Question #31
An EMC Disk Library customer is considering using Remote Copy between two engines. A policy will be configured to copy data when 50 MB of data is sent to the virtual tape. How does the data transfer occur?
  1. A
    Whole content of the virtual tape is sent to the target once the first 50 MB is stored in the buffer
  2. B
    Incremental data is sent to the target engine when the virtual tape is unmounted and 50 MB of new data has been written
  3. C
    Incremental data is sent immediately to the target engine as soon as 50 MB of new data is received by the virtual tape during the backup process
  4. D
    Incremental data is sent to the target in 50 MB increments whenever the virtual tape is idle

Correct Answer:
B

Question #32
Given an RPO, which factors must be considered when designing an EMC NetWorker backup solution?

  3. C
    Retention period and backup level
  4. D
    Multiplexing and client parallelism

Correct Answer:
B

Question #33
A customer has two sites with 50 clients at each site. The customer wants the backup to occur locally on tape media at each site and would like to have a single

  1. A
    Dedicated storage node
  2. B
    Deduplication node
  3. C
    Storage node
  4. D
    NetWorker server

Correct Answer:

  3. C
    Spoofed WWNs for all initiators
  4. D
    Minimum of two GigE ports configured for LACP

Correct Answer:

Question #35
In an EMC NetWorker datazone, which component stores the online databases that track backups and volumes?
  1. A
    Management Console Server
  2. B
    Server
  3. C
    Storage node
  4. D
    Media server

Correct Answer:

  1. A
    Deploy agents to the guest VMs
  2. B
    Deploy agents to the ESX console
  3. C
    Use VMware Consolidated Backup
  4. D
    Leverage storage-based snapshot backups

Correct Answer:
A

Question #37

  1. A
    Proxy server
  2. B
    Storage node
  3. C
    Management host
  4. D
    Virtual tape library

Correct Answer:

Question #38
Which Data Domain feature is used to selectively replicate data written to the Data Domain Virtual Tape Library (DD-VTL) by the backup software?
  1. A
    Tape Import/Export
  2. B
    Access Groups
  3. C
    Tape Pools
  4. D
    Virtual Vault

Correct Answer:
D

Question #39

  1. A
    Advanced File
  2. B
    File
  3. C
    Virtual Tape Library
  4. D
    Tape

Correct Answer:
A

Question #40
A customer, using Avamar version 4, wants to use VMware Consolidated Backup (VCB) to back up their version 3.x ESX servers. Which operating system(s) can they run on their proxy server?
  1. A
    Microsoft Windows 2003 and Red Hat Enterprise Linux 4
  2. B
    Microsoft Windows 2003
  3. C
    Microsoft Windows 2003 and Windows 2008
  4. D
    Red Hat Enterprise Linux 4

Correct Answer:
B
Avamar VCB Interoperability Module. The Avamar agent and the interoperability module run on the Consolidated Backup proxy server to provide the backup services. One backup server can provide backup services to many ESX server hosts, as long as all machines share the same SAN (storage area network).
With this approach, users have several advantages. By consolidating backups onto fewer proxy servers, backup can be simplified and backup licensing costs for
VMware environments can be reduced. VCB reduces the load on the ESX Server during backups, eliminating the need to manage backup agents in each virtual machine. And, because of its method of transferring data using the SAN, LAN traffic associated with backup is reduced. With this approach, there is no direct application integration as is possible with guest backups using Avamar database plug-ins.
Note: Backup proxy server supported on Windows 2003 server only.
