EMC E20-329 Online Questions & Answers

• Question 51:

  A company has a large Oracle database and is using NetWorker Module for Databases and Applications for its backup. In this backup environment all the servers are impacted due to the huge volume of backup data. Which solution would minimize the impact on the backup environment?

  A. Back up only changed data instead of daily full backup
  B. Include all database objects along with system tables
  C. Use Microsoft VSS to create snapshots
  D. Use Replication Manager along with the NMDA
  A. Back up only changed data instead of daily full backup

  A. 5
  B. 10
  C. 12
  D. 24
  A. 5

• Question 53:

  You are designing an EMC Data Domain solution and need to determine the required amount of storage capacity. The following information was gathered from the customer: 2 TB full backup @ 5x compression 10% daily data change rate 4 incremental/week @ 10x compression 1x full per week @ 25x compression Retention period = 4 weeks with no data growth

  What is the minimum amount of storage needed to support this solution?

  A. 850 GB
  B. 900 GB
  C. 1040 GB
  D. 1200 GB
  C. 1040 GB

• Question 54:

  An EMC Avamar customer has a heavily utilized ESX system where CPU utilization is a concern. Each guest system, all of which are Linux, must be backed up with file granularity. The customer has both Avamar and NetWorker available and is looking to EMC for guidance

  What is considered the most suitable approach to meet these requirements?

  A. Install the Avamar agent directly on each guest system
  B. Install the NetWorker agent directly on each guest system
  C. Use Avamar VCB to offload the ESX server
  D. Use NetWorker VCB to offload the ESX server
  B. Install the NetWorker agent directly on each guest system

• Question 55:

  A customer wants to perform a data center refresh. They want to standardize their backup infrastructure by using EMC NetWorker and Data Domain in an integrated environment.

  The environment consists of:

  A primary data center with NetWorker and Data Domain

  220 remote sites; each remote site consists of 30 clients and one storage node with three devices per storage node. Each remote storage node 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 56:

  A company has a business model where they purchase small companies and let them run independently. Storage, backup and recovery, and server technology implementations vary between the companies.

  The company has determined that they must initiate a backup and recovery strategy that will allow for recovery of any of the small companies in case of a complete site failure. In addition, they want to start to use a single standard model in an effort to move forward towards standardization across the entire enterprise. A backup and recovery audit has found that the companies all use a basic method of backup and recovery consisting of enterprise backup software backing up to a tape library for all critical corporate data. The company wants to replicate

  backup sets from each site to their corporate location.

  Which EMC solution should be used to minimize impact on the environment while minimizing cost?

  A. Install Avamar as the backup technology at each site and replicate to a central Avamar for recovery
  B. Install Data Domain as a VTL for each site and replicate to a central Data Domain for recovery
  C. Install Data Domain as a VTL with NetWorker for each site and replicate to a central Data Domain for recovery
  D. Install NetWorker at each site and configure NetWorker Archiver to a central Data Domain for recovery
  C. Install Data Domain as a VTL with NetWorker for each site and replicate to a central Data Domain for recovery

• Question 57:

  A customer has two data centers and each data center has an identical EMC Data Domain system. The customer needs a replication strategy that meets the following objectives:

  User name and passwords are unique /data/col1/backup are identical Data Domain destination directory is read only Ownership and permissions remain identical

  Which type of Data Domain replication should be configured?

  A. Directory
  B. Collection
  C. MTree
  D. Pool
  A. Directory

• Question 58:

  A customer has 20,000 desktop/laptop (DT/LT) clients and six new Avamar 1x16 servers. They are having difficulty with initial backups and backups not completing during the backup window. Based on best practices, which recommendation can be provided to address these issues?

  A. Bring new clients online in batches of 160 per Avamar server and take advantage of partial backups.
  B. Implement overtime on all new clients and migrate clients with incomplete backups to dedicated servers.
  C. Bring new clients online in batches of 1600 per Avamar server and implement overtime on clients that fail to backup the first time.
  D. Automate the entire operation with the Avamar Installation Manager features.
  A. Bring new clients online in batches of 160 per Avamar server and take advantage of partial backups.

• Question 59:

  A customer has recently purchased Data Protection Advisor (DPA) to monitor their EMC NetWorker backup environment. They are currently monitoring the NetWorker servers and storage nodes. Which other devices can be monitored without additional DPA licenses?

  A. Physical or virtual tape libraries, IP and Fibre Channel switches, and databases on backup clients
  B. NAS devices and performance data on backup clients
  C. IP switches, Fibre Channel switches, tape libraries, and NAS devices
  D. Physical or virtual tape libraries and IP or Fibre Channel switches only
  A. Physical or virtual tape libraries, IP and Fibre Channel switches, and databases on backup clients

• Question 60:

  Refer to the Exhibit.

  

  A large mining company wants to implement replication using EMC Data Domain systems in multiple cities. How should the customer's design requirements be addressed?
