EMC E20-329 Online Questions & Answers

• Question 231:

  Refer to Scenario .

  

  The Chief Technical Officer (CTO) of a large company has directed their IT management staff to examine corporate wide operations and find ways to limit the cost of operations. The corporate directives have prompted adoption of company policies that include the use of virilization for all new servers and as many services as possible. The company is subject to government regulations concerning data retention policies for confidential data. Data has to be retained for seven years.

  An audit of the backup and recovery environment is performed. The exhibit shows a typical site and how it is connected to the disaster recovery environment. Data in the primary site is configured on VMAX storage using FAST-VP to support multiple work load types on a single storage array.

  Data is protected by SRDF/A to a remote VMAX which acts as a target for multiple sites. The remote copy of the data is snapped and copied to tape. Retention is accomplished to governmental standards by offsite storage of tape in a remote protected facility.

  The company has noted that it has the following requirements in any proposed architecture for the backup and recovery environment:

  1.

  Reduced power consumption

  2.

  Reduced floor space consumption

  3.

  Reduced storage capacity consumption

  4.

  Lower WAN bandwidth utilization

  5.

  Shorten RPO

  6.

  Decrease RTO

  7.

  Increase security

  8.

  Lower Total Cost of Ownership (TCO)

  To satisfy the stated requirements, the customer wants to use a virtual appliance to limit power and space consumption in their smaller locations. To replace the current SRDF/A replication model, which EMC technology should be recommended?

  A. Data Domain
  B. NetWorker NDMP
  C. Avamar AVE
  D. NetWorker Archiver
  A. Data Domain

• Question 232:

  A new EMC Avamar customer wants advice on setting up their groups and schedules. The customer has a mixed environment and is migrating from a traditional tape backup solution with a mixed retention policy. Which follows EMC best practices for setting up groups and policies?

  A. Minimize the number of groups, combine different OSs in datasets, and implement advanced retention.
  B. Group clients by OS, make unique datasets for each OS, and create unique retention policies for Monthly, Daily, Weekly, and Yearly.
  C. Enable the default group and use the group for all policies. Every client is added to this group upon activation.
  D. Create a unique group for each dataset, schedule, and retention.
  A. Minimize the number of groups, combine different OSs in datasets, and implement advanced retention.

• Question 233:

  A customer wants to determine how much data can be transmitted in their network. The network environment includes the following:

  LAN speed = 4 Gb Bandwidth = 50 Mbps RTT = 50 ms

  What is the customer's bandwidth delay product (BDP)?

  A. 2000 bytes
  B. 76 Kb
  C. 305 Kb
  D. 5 MB
  C. 305 Kb

• Question 234:

  An EMC Data Domain customer is planning to implement a replication solution in order to have their production environment protected at a remote site. The bandwidth for their SRDF replica is 40 Mbps which they are planning to share with the Data Domain replica.

  

  Based on the exhibit and given an 8-hour replication window, which information will determine the bandwidth requirements?

  A. Post-Comp in the last 24 hours
  B. Pre-Comp in the last 7 days
  C. Currently used Post-Comp
  D. Post-Comp in the last 7 days
  A. Post-Comp in the last 24 hours

• Question 235:

  A customer currently 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.
  B. Add one node at a time.
  C. No more nodes can be added. Add a new Avamar system.
  D. No more nodes can be added. Migrate to a larger Avamar system.
  A. Add two nodes at a time.

• Question 236:

  An EMC NetWorker customer is considering backup options for their VMware environment. The environment consists of Microsoft Windows file servers an Oracle database server running on Solaris. What is an advantage of using the VMware image backup operation?

  A. Application backup data is crash-consistent
  B. File-level restore granularity available for all systems
  C. Low load on the ESX server during backups
  D. No proxy server required for the backup environment
  A. Application backup data is crash-consistent

• Question 237:

  An organization is backing up a combination of databases, e-mail, and file system data types in their data center to a Data Domain appliance using a single backup server. The backup system administrator creates separate subdirectories for each of the three data types under the default share.

  What benefit is provided by this approach?

  A. Analyze compression with moregranularity
  B. Simplify backup device configuration
  C. Enhance performance of the database backup
  D. Improve file system cleaning performance
  A. Analyze compression with moregranularity

• Question 238:

  A customer is considering the use of offsite physical tape vaulting rotation for compliance purposes. What is a key concern to discuss with the customer?

  A. Additional resources needed during the backup window for the production data
  B. Amount of tape media is twice as large as the actual production data size
  C. Inefficient tape media utilization when adhering to time-regulated timetables
  D. Media retention is always three times the length of the RPO value
  C. Inefficient tape media utilization when adhering to time-regulated timetables

• Question 239:
