• Question 81:

  A customer has a 1 TB Oracle 10g database on a HP-UX 11.31 client. They have created two groups that run once every 24 hours. One group is for backing up the database; the other group is for backing up the file system. During the course of a week, the customer notices that the client is taking up twice the space as expected. What is a probable cause?

  A. Client is being backed up twice
  B. DBF files are not excluded in the file system dataset
  C. Group that backs up the database is being run twice a day
  D. Block Change Tracking is not being used
  B. DBF files are not excluded in the file system dataset

• Question 82:

  A customer with an existing Dell EMC NetWorker environment has recently added a Dell Avamar system to their environment. Avamar NDMP will be used to back up their VNX. In addition, the customer has a requirement to write the NDMP backup data from Avamar to tape on a weekly basis. ADMe, installed on the Avamar utility node, will be used for this purpose.

  Which methods can be used to automatically schedule ADMe batch jobs?

  A. CRON on the utility node and NetWorker Management Console
  B. CRON on the staging server and Avamar scheduler
  C. CRON on the staging server and NetWorker Management Console
  D. CRON on the utility node and an External third-party scheduler
  A. CRON on the utility node and NetWorker Management Console

• Question 83:

  A customer set up their Dell EMC VNX to back up through a Dell EMC Avamar NDMP Accelerator node. They are not seeing any increased performance since the initial backup. In addition, they have investigated the VNX and there are no outstanding issues.

  What is a potential reason for the poor backup performance?

  A. Dataset options are set to Level 0.
  B. The dataset advanced option is blank.
  C. Data has a low change rate.
  D. File cache is using demand-paging.
  A. Dataset options are set to Level 0.

• Question 84:

  An EMC Partner has a 1 X 3 Avamar server. They would like to leverage their Avamar server to back up data from multiple customers. They have 4,000 desktop clients to back up within 6 hours. Each client takes up to 20 minutes to complete a backup.

  What is recommended?

  A. Add one storage node to the Avamar server.
  B. Schedule backups to start at different times.
  C. Add 500 clients to each backup group.
  D. Break the backups into smaller datasets.
  A. Add one storage node to the Avamar server.

• Question 85:

  A database administrator added a DB2 database that is being backed up online through the Avamar DB2 plug-in. They have been instructed to shorten the backup time of the database due to the Avamar backup window being quite full when the backup takes place. To accomplish this, they have excluded the archive logs from the dataset.

  What else must the administrator do to ensure that no data loss occurs in the event they need to restore the database?

  A. Include the archive logs in the file system backup.
  B. Back up the archive logs separately using the DB2 plug-in.
  C. Perform an offline backup of the database.
  D. Perform an offline backup of the archive logs using the DB2 plug-in.
  A. Include the archive logs in the file system backup.

• Question 86:

  An EMC Avamar customer has an IBM DB2 server with multiple instances; i.e., A, B, and C.

  A. Migrate Instances B and C to two new DB2 servers
  B. Run db2 update db cfg for using LOGRETAIN ON for each instance
  C. Create a file system backup schedule to include the archive logs for each instance
  D. Modify the schedules for each instance to ensure they do not run simultaneously

  A. Migrate Instances B and C to two new DB2 servers

• Question 87:

  A Dell EMC Avamar backup administrator is configuring image level backups of six VMware VMs using a proxy. However, the initial backups are failing. What is a possible cause for the failures?

  A. Proxy client is not assigned to the datastore
  B. Maximum number of concurrent backups is exceeded
  C. Proxy cannot access the file cache
  D. Backup client is not installed on the VMs
  A. Proxy client is not assigned to the datastore

• Question 88:

  An EMC customer is protecting 3000 virtual machines (VMs) with guest level backup. All VMs reside on the same ESX server. The administrators are concerned with the CPU spike during backups since Avamar is trying to initiate as many

  backups as possible.

  What is the best practice for preventing this spike in CPU on the ESX server host?

  A. Use network throttling parameters in the advanced options tab of the dataset
  B. Break the VMs up into multiple groups that run at different times C. Use the Backup Priority attribute in the Group settings
  D. Migrate some of the VMs to another ESX host
  A. Use network throttling parameters in the advanced options tab of the dataset

• Question 89:

  A database administrator wants to perform a restore from an online backup of their DB2 database that was taken the previous day via DB2 CLP. Upon looking at the backups from the previous day in Avamar Administrator, they notice multiple backup names are present.

  Which backup should they choose?

  A. CLI-H-DB2 Database(s) backup
  B. GUI-H-DB2 Database(s) backup
  C. CLI-C-DB2 Database(s) backup
  D. GUI-C-DB2 Database(s) backup
  A. CLI-H-DB2 Database(s) backup

• Question 90:

  A customer has an EMC VNX and a NetApp filer that they are using to provide network shares to their employees. The content on these devices is being protected by an EMC Avamar 7.0 with one accelerator node. The backup data is stored

  on an integrated Data Domain running 5.3.

  They are planning to consolidate their mixed environment by replacing the VNX and NetApp filers with two EMC Isilon systems.

  What other changes must be made to support the new configuration?

  A. Backup data will have to be stored on the Avamar server.
  B. A second accelerator node will have to be configured.
  C. The accelerator node will need to be configured for dual NIC operation.
  D. The Data Domain OS must be upgraded to 5.4.
  A. Backup data will have to be stored on the Avamar server.
