Free Dell EMC DES-3128 Exam Actual Questions

The questions for DES-3128 were last updated On Apr. 11, 2024

Question #1

An administrator wants to make sure Oracle backups only use a specific storage node.

Use the simulator to configure an AFTD Device on "StorageNodeA" with the name "OracleBackup" using the folder "D \AFTD" to the pool "Default". This storage node should be a dedicated storage node

When you have finished, continue to the next question.

AExplanation:
To configure an AFTD device on 'StorageNodeA' with the name 'OracleBackup' using the folder 'D:\AFTD' to the pool 'Default', the administrator can use the Data Domain CLI (Command Line Interface) to access the Data Domain system and create the AFTD device. Here are the steps:
Log in to the Data Domain CLI by entering the following command:
ssh admin@StorageNodeA
Once logged in, create a new AFTD device named 'OracleBackup' by entering the following command:
ddboost afd create --name OracleBackup --pool Default --folder D:\AFTD
Verify that the new AFTD device has been created by running the following command:
ddboost afd show --name OracleBackup
To make sure that the Oracle backups only use the specific storage node, you can assign the AFTD device to the Oracle backup host by running the following command:
ddboost afd set --name OracleBackup --host OracleBackupHost
Verify the configuration by running the following command:
ddboost afd show --name OracleBackup
To make sure that the StorageNodeA is a dedicated storage node, you can configure the storage node to only allow the OracleBackup host to use the AFTD device by running the following command:
ddboost host access add --host OracleBackupHost --afd OracleBackup
Finally, the administrator should select the ''Apply'' button to save the configuration.

Question #2

A customer checks the rap log on a NetWorker server to audit recent resource changes, but the file is empty.

What is the cause of the issue?

AThe Monitor RAP attribute on a NetWorker Client is disabled.

BPermission issues for the log are not set.

CPermission issues for the log are set.

DThe Monitor RAP attribute on a NetWorker Server is disabled.

Reveal Solution

Correct Answer: D

The rap log on a NetWorker server is used to audit recent resource changes, and if the file is empty, it is likely because the Monitor RAP attribute on the NetWorker server is disabled. This attribute must be enabled in order for the rap log to be updated. The other options are not related to the cause of the issue.

Question #3

An administrator wants to create a client "ABO" to back up alt critical volumes for disaster recovery. They want the backup utility to scan a volume or a disk m a file system and back up all the blocks that are in use in the file system

Also, the user has a feature that allows for a single high-density file system to be spirt into multiple concurrent save sets to speed up the backup walk process. The client must send 6 save sets simultaneously in a backup.

Use the simulator to perform the task

When you have finished, continue to the next question.

AExplanation:
The steps to create a client 'ABO' to back up critical volumes for disaster recovery and to use the feature that allows for a single high-density file system to be split into multiple concurrent save sets are as follows:
Create the client:
On the NetWorker server, open the NetWorker Management Console.
Go to the Clients tab.
Click on the Add button.
In the Client Name field, enter 'ABO'.
In the Client Address field, enter the IP address or hostname of the client.
In the Platform field, select the appropriate platform for the client.
Click on the OK button to create the client.
Configure the client:
Go to the Clients tab.
Click on the ABO client.
Go to the File Systems tab.
Click on the Add button.
In the File System field, enter the path of the critical volume that needs to be backed up.
In the Save Set field, enter a name for the save set.
Check the Include all blocks that are in use option. This will ensure that all blocks that are in use in the file system are backed up.
Click on the OK button to add the file system.
Configure the save set:
Go to the Clients tab.
Click on the ABO client.
Go to the Save Sets tab.
Click on the save set that you just created.
Go to the Advanced tab.
In the Save Set Options field, enter 'PSS:streams_per_ss=6'. This tells NetWorker to split the save set into 6 concurrent save sets and send them simultaneously in a backup.
Click on the OK button to save the changes.
Schedule the backup:
Go to the Clients tab.
Click on the ABO client.
Go to the Schedules tab.
Click on the Add button.
Select the appropriate schedule for the backup.
In the Save Set field, select the save set that you just created.
Click on the OK button to schedule the backup.
