• Question 172:

  A single-engine EMC Disk Library (EDL) is being proposed with Remote Copy functionality replicate data to a remote EDL. One of the EDLs will have four network connections while the other one will have two network connections. How many ports will be used in each EDL during a replication session?

  A. 1
  B. 2
  C. 3

  A. 1

• Question 173:

  A backup administrator has added a large database server with a low change rate to their Avamar server as a new backup client. The database server is located remotely and the network connection is not consistent. The server backup continuously runs into overtime and fails due to network issues. As a result, the initial backup has not completed. The backup administrator asks you for advice on how to ensure successful backups.

  What should you tell the backup administrator?

  A. Disable overtime for the client
  B. Continue from partial backups
  C. Perform incremental backups
  D. Copy cache files from a similar database server
  A. Disable overtime for the client

• Question 174:

  An existing EMC Avamar customer wants to add a new file system client to their Avamar system. This is a moderately full Avamar single-node server running in steady state. What is the estimated time to backup this file server of 3 million files?

  A. Less than 1 hour
  B. 1-2 hours
  C. 3-4 hours
  D. 5-6 hours
  C. 3-4 hours

• Question 175:

  An EMC NetWorker customer is considering backup options for their VMware environment. What is an advantage of using the VMware Console Backup option?

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

• Question 176:

  An EMC NetWorker customer has been using an EMC Disk Library (EDL) for over four years. The EDL has reached its capacity limits. The customer is in the process of virtualizing as many physical servers as possible to reclaim data center

  floor space. They are backing up numerous 8 TB databases.

  The customer is interested in replacing the EDL and is concerned about the amount of backup traffic over the network. The replacement must maintain a single point of backup administration and reduce backup times for their growing

  virtualized environment.

  What is the recommended solution?

  A. Replace the EDL with Data Domain using DD Boost
  B. Add a deduplication storage node to NetWorker for VMware backups and replace the EDL with Data Domain for large databases
  C. Add an Avamar server for VMware backups and use NetWorker with DD Boost to back up the physical servers and large databases to a Data Domain
  D. Add a deduplication storage node to NetWorker for database backups and replace the EDL with Data Domain for VMware and physical servers
  D. Add a deduplication storage node to NetWorker for database backups and replace the EDL with Data Domain for VMware and physical servers

• Question 177:

  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.

  The LAN administrator has indicated that the least amount of traffic should traverse the network. Based upon this requirement, what is the recommended solution?

  A. Client Direct to Data Domain
  B. Client Direct to Avamar
  C. Traditional backup
  D. VADP backup using NBD transport mode
  A. Client Direct to Data Domain

• Question 178:

  A customer has asked you to assess their current backup environment. The environment is currently using an offsite physical tape vaulting rotation for compliance purposes. What is a key concern that you should discuss with the customer?

  A. Recovery data is at least one backup cycle behind the production site in the event of a disaster
  B. Media retention period consideration is three times the length of the RPO value
  C. Need for additional resources during the backup window for the production data
  D. Amount of tape media is consistently double the size of the actual production data
  A. Recovery data is at least one backup cycle behind the production site in the event of a disaster

• Question 179:

  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 configured and set up properly for the customer environment.

  What is a design consideration for the NetWorker backup server?

  A. RAID 10 is recommended for the NetWorker server if the NetWorker server exceeds 100 parallel sessions.
  B. RAID 5 is recommended for the NetWorker server if the NetWorker server exceeds 100 parallel sessions.
  C. Set NetWorker server Parallelism to the total number of Max Sessions on all devices.
  D. Create multiple NetWorker groups with a maximum of 100 clients per group and enforce Group Parallelism.
  A. RAID 10 is recommended for the NetWorker server if the NetWorker server exceeds 100 parallel sessions.

• Question 180:

  A web-based service customer is using EMC NetWorker to backup their environment. The environment consists of various departments located across different buildings in the same campus with a dedicated backup infrastructure. All

  backups are sent to a central location.

  They are experiencing issues in which the 2 TB database backup jobs are not completing within the backup window. They want a replication solution that will have minimal impact on the NetWorker server and lower TCO.

  What should be recommended to resolve the issue and implement an efficient replication plan?

  A. Integrate Data Domain into NetWorker
  B. Deploy Avamar and integrate into NetWorker
  C. Convert all large clients to storage nodes
  D. Use the NetWorker Multi-Tenancy feature
  A. Integrate Data Domain into NetWorker
