EMC E20-329 Online Questions & Answers

• Question 281:

  You are asked to design an EMC NetWorker backup solution for a customer's data center with multiple database applications and a large amount of clients and data. The NetWorker backup server needs to be sized and configured properly for the customer environment.

  D. Create multiple NetWorker groups with up to 100 clients per group and disable Group Parallelism.
  A. Assign large clients to a separate NetWorker group and start the group first.

• Question 282:

  An existing EMC NetWorker customer is planning to integrate EMC Data Domain systems into their backup infrastructure. They would like to:

  Backup their Microsoft Windows client data using CIFS to a Data Domain system Take weekly Data Domain system snapshots of Windows client backup data Backup their Linux client data using NFS to a Data Domain system Take daily Data Domain system snapshots of Linux client backup data Based on EMC best practice, what should be considered when designing the Data Domain file system layout?

  A. Create a separate MTree for CIFS and NFS client data
  B. Create an MTree named "data" and create separate sub-directories for CIFS and NFS client data
  C. Under /backup MTree, create separate sub-directories for CIFS and NFS client data
  D. Create separate storage units for CIFS and NFS client data
  A. Create a separate MTree for CIFS and NFS client data

• Question 283:

  A customer wants to back up VMware using Avamar to leverage deduplication. They have been and want to continue performing VCB backups. Where will the Avamar client and the Avamar VCB Interoperability Module be installed?

  A. Backup proxy server
  B. ESX server and backup proxy server
  C. Virtual machines guest operating system
  D. Virtual machines and backup proxy server
  A. Backup proxy server

• Question 284:

  Scenario

  A customer with a fully virtualized environment has four ESX 4.1 servers in a cluster with a SAN solution for storage. Each ESX server is hosting 40 virtual machines and all virtual machines have the same local disk configurations: Disk1 = 50 GB Disk2 = 100 GB Disk3 = 256 GB

  In addition, the environment includes a NAS filer. The average time to fully backup all virtual machines on one ESX server using EMC DD Boost is three hours. The customer is interested in implementing an EMC NetWorker solution with Data Domain as a backup device. The backup server, storage nodes, and proxies are SAN-attached.

  Refer to Scenario .

  When using EMC NetWorker and DD Boost, what is the maximum number of concurrent backups per VADP proxy server?

  A. 40
  B. 50
  C. 100
  D. 160
  C. 100

• Question 285:

  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.

  Each remote storage nodes' device will have a target session of 12 and a max target session of

  60. By default, what is the maximum nsrmmd count per device?

  A. 5
  B. 9
  C. 12
  D. 60
  B. 9

• Question 286:

  You are designing an EMC Data Protection Advisor (DPA) solution for a large NetWorker customer using both DPA clustering and replication. What is a consideration when determining the server layout for application and datastore servers?

  A. Implement DPA clustering in a virtualized environment
  B. Use clusters containing both application and datastore servers
  C. Connect a DPA datastore to each cluster VLAN in the solution
  D. Configure DPA replication between master and secondary application servers
  A. Implement DPA clustering in a virtualized environment

• Question 287:

  A Symantec Backup Exec customer purchased an EMC Disk Library (EDL) last year and performs 1.5 TB of nightly backups. Backup Exec is used to copy EDL virtual tapes to physical tapes to satisfy offsite requirements. The daily backup and tape copying workload is becoming a challenge for their Backup Exec server.

  The customer is exploring EDL-to-EDL replication to a second a second site seven miles always to eliminate physical tape and reduce the Backup Exec server workload. Which EDL relocation option meets the customer's requirements?

  A. Remote Copy over an IP connection
  B. Consolidated Media Management over extended Fibre Channel
  C. Tape Caching over extended Fibre Channel
  D. Auto Archive over an IP connection
  A. Remote Copy over an IP connection

• Question 288:

  An EMC NetWorker customer wants to use the deduplication option. The requirement for a database server in their environment is to perform deduplication backups for file system data and NetWorker tape backups for database data. They want to allow a maximum of two parallel streams for file system backups and a maximum of four streams for database backups.

  How can this be accomplished?

  

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  C. Option C

• Question 289:

  Refer to the exhibit.

  

  An EMC Data Domain customer is running the backup and recovery configuration shown in the exhibit. They plan to increase their capacity use by 25% each year. The expected life of the configuration is four years.

  What should be done first to validate the design of the system?

  A. Capture baseline performance of the EMC NetWorker server
  B. Configure Email Home for the EMC Data Domain VTL
  C. Capture baseline performance of client servers
  D. Configure network monitor
  A. Capture baseline performance of the EMC NetWorker server

• Question 290:

  An EMC NetWorker customer has three backup servers with four storage nodes reporting to each of the backup servers. All servers run Microsoft Windows. A dual-engine EMC Disk Library with Active Engine Failover is being proposed for

  this environment with embedded storage nodes for to physical tape.

  A. Active Engine Failover is unsupported in a Windows environment
  B. Multiple instances of the embedded storage node will need to be configured
  C. Each embedded storage node can only serve a single data zone
  D. NetWorker servers must be configured as read storage nodes for the cloning operation
  B. Multiple instances of the embedded storage node will need to be configured
