DES-3128 Sample Questions Answers

To create the desired configuration, you will need to use the Data Domain CLI (Command Line Interface) to access the DD Boost device and create the new appliance. Here are the steps:

• Log in to the Data Domain CLI by entering the following command:

ssh ddboost@DD0

• Enter the password "abc123" when prompted.
• Once logged in, create a new DD Boost device named DD01.SU01 by entering the following command:

ddboost device create --name DD01.SU01 --type vmware --pool DO.VMware_Pool

• Verify that the new device has been created by running the following command:

ddboost device show --name DD01.SU01

• Configure the DD Boost device to connect to the PowerProcted DO series appliance by running the following command:

ddboost device set --name DD01.SU01 --dd-host DD0

• Verify the configuration by running the following command:

ddboost device show --name DD01.SU01

To troubleshoot why a customer cannot see any files backed up when a restore operation is attempted on their 3 new Linux server named Server01, the first step should be to check the log files for any error messages. The log files are typically located in the /var/log/ directory, but the exact location may vary depending on the operating system being used.

Next, the administrator should check the configuration of the NetWorker server to ensure that the server is configured correctly. This includes checking the client configuration for the Server01 and making sure that the correct client name is being used. Additionally, the administrator should make sure that the Server01 has the correct address and port information, as well as the correct credentials.

The administrator should also check the configuration of the server to make sure that the correct backup policies are being used and that the backup schedule is configured correctly. Additionally, they should check the configuration of the actual backup device, such as the tape library or disk array, to make sure that it is configured properly.

Finally, the administrator should check the filesystem of the Server01 to make sure that the backup files are actually being written to the correct location.

To create a new NSR Client "ABC 123" and PSS file system backup save sets /data01 and /data02, and a skip files directive named "Skip GO" for * .go extensions anywhere under /data02, the administrator can use the Networker CLI (Command Line Interface) to access the Networker server and create the NSR Client, PSS file system backup save sets, and skip files directive. Here are the steps:

• Log in to the Networker CLI by entering the following command:

nsr_client -C ABC 123

• Once logged in, create a new PSS file system backup save set for /data01 by running the following command:

savefs -p -s /data01

• Create a new PSS file system backup save set for /data02 by running the following command:

savefs -p -s /data02

• Create a skip files directive named "Skip GO" for * .go extensions anywhere under /data02 by running the following command:

savefs -p -s /data02 -k "* .go"

• Verify that the new NSR client, PSS file system backup save sets and skip files directive have been created by running the following command:

nsr_client -l

• Verify that the new PSS file system backup save sets are correctly associated with the new NSR client by running the following command:

nsr_client -G ABC 123

NetWorker does not directly support the backup of mount points on Linux systems. To back up the data on the mount points, the remote systems must be added as a client to the NetWorker server and included in the backup.

To install a virtual CloudBoost appliance on a VMware ESXi host, the backup administrator must deploy an OVF template. This will deploy the appliance on the ESXi host and configure the settings for the appliance.

NetWorker does not support recovery from aborted save sets, so the administrator should inform the customer that the data backed up before the backup was stopped cannot be recovered.
