Question 1

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.

Answer : A

Question 2

Which NetWorker component is comprised of a single NetWorker Server, its clients, and storage nodes?

Amedia pool

Bsave set

Cdatazone

Dprotection group

Answer : C

A datazone is a NetWorker component composed of a single NetWorker Server, its clients, and storage nodes. It is used to define a group of systems and storage nodes that will share the same configuration. The media pool, save set, and protection group are all related to NetWorker, but they are not components of a datazone.

Question 3

A NetWorker server is utilizing a remote storage node. A media library with two LTO Ultnum-8 drives is attached to the storage node via Fiber Channel interface. There is an AFTD device labeled to the Dally pool, and a media library has several cartridges labeled for the Weekly pool.

All devices are configured on the storage node. A Windows 2019 client is being backed up to the Daily pool while the Client Direct option is enabled in the client's properties.

What is the correct data flow?

AThe storage node writes the data to the LTO Ultrium-8 device.

BThe storage node writes the data to the AFTD device.

CBackup data is being written directly to the LTO Ultrium-8 device.

DBackup data is being written directly to the AFTD device.

Answer : A

In this scenario, the NetWorker server is utilizing a remote storage node with a media library containing two LTO Ultnum-8 drives. The AFTD device is labeled to the Dally pool and the media library has several cartridges labeled for the Weekly pool. When the Client Direct option is enabled in the client's properties, the storage node writes the backup data to the LTO Ultrium-8 device.

Question 4

A backup administrator wants to use an mminfo utility to run a query for several save sets from a NetWorker client running Windows 2019 However, they receive an error that the mminfo executable is not found.

What is the fastest way to resolve this issue?

AInstall the NetWorker Extended Client package.

BUse an nsrinfo utility instead

COpen a case with Dell Support

DUse a Windows Explorer to find the mminfo.exe file

Answer : A

To use the mminfo utility, the NetWorker Extended Client package must be installed to the Windows 2019 client. This package includes the mminfo executable along with other NetWorker utilities.

Question 5

A DB2 database is running on an IBM AIX operating system. A customer asks an administrator to configure a backup with NetWorker.

How should the administrator respond?

AAIX backup is not supported

BNMM must be installed

CNo additional module is required.

DNMDA must be installed

Answer : D

To configure a backup of a DB2 database running on an IBM AIX operating system with NetWorker, the administrator must first install the NetWorker Module for Databases and Applications (NMDA).

Question 6

A NetWorker server has a media library attached. A customer needs to back up their VMware environment using vProxy A designated pool was created for the VMware backups However, this pool is not listed in the drop-down menu during a backup action creation.

What is the cause of this behavior?

AA vProxy is disabled

BvProxy backups can only be directed to CloudBoost devices.

CThe media library is disabled.

DvProxy backups can only be directed to Data Domain devices.

Answer : A

The cause of the behavior is that a vProxy is disabled. When a vProxy is disabled, it will not be available for selection in the drop-down menu during a backup action creation. This means that the vProxy cannot be used to perform backups of the VMware environment. To solve this issue the vProxy needs to be enabled.

It's worth mentioning that vProxy is a NetWorker feature that allows backups of VMware environments by communicating with vCenter or ESX servers. It uses the VMware APIs to access and back up virtual machines. And, it's also worth noting that vProxy backups can be directed to different types of devices like disk, tape, and deduplication devices like Data Domain and CloudBoost.

Question 7

What resource does NetWorker use to protect VMware objects, save sets, or clients?

AData Protection Policy

BActions

CWorkflows

DProtection Group

Answer : D

NetWorker uses Protection Groups to protect VMware objects, save sets, or clients. Protection Groups allow you to group related objects together, making it easier to manage and run backups.
