After completing an upgrade of all DP4400 components, the backup jobs fail to start in Avamar.
What should you check FIRST?
- A . VMware license activation
- B . DNS resolution of the Data Domain
- C . Service status using dpnctl status
- D . Upgrade logs in /var/log/vmware
C
Explanation:
Verifying whether Avamar services are properly running is the first logical step. If services were not restarted or failed during upgrade, backup jobs won’t execute.
After an ESXi upgrade, how should you verify if the upgrade was successful?
- A . Check the iDRAC logs
- B . Run system show version
- C . Use the vSphere Web Client to check the host version
- D . Monitor Avamar deduplication statistics

After upgrading ESXi, the vSphere Web Client provides system details to verify the updated version.
After enabling Cloud Tier on the Data Domain system, a warning appears stating that “cloud credentials are invalid.”
What should you check FIRST?
- A . Whether cloud lifecycle policies are active
- B . Whether the DD Boost service is stopped
- C . Whether the correct access keys and bucket name are entered
- D . Whether Avamar has access to the internet
C
Explanation:
Cloud Tier requires valid cloud storage credentials (e.g., AWS Access Key and Bucket Name). An error here prevents any movement of data to cloud storage.
If a backup job fails immediately in Avamar, what is the MOST likely root cause?
- A . RAID failure on Data Domain
- B . Client DNS or NTP misconfiguration
- C . Missing ESXi license
- D . Avamar service overload
B
Explanation:
Incorrect DNS or time settings between client and Avamar commonly cause immediate backup job failures.
What is the purpose of the “Deploy OVF Template” process in vSphere during Avamar installation?
- A . To install Data Domain OS
- B . To update VMware Tools
- C . To deploy the Avamar virtual appliance
- D . To configure DNS settings
C
Explanation:
The “Deploy OVF Template” function is used in vSphere to install virtual appliances such as Avamar by importing the OVA file.
After a weekend, you log in to the Data Domain system and see a “High Storage Utilization” alert.
Which action should you perform FIRST to address the issue?
- A . Expand the storage pool with new disks
- B . Delete older backup sets manually
- C . Run filesys clean start to remove orphaned and expired data
- D . Disable replication temporarily
C
Explanation:
Initiating a file system clean helps reclaim space by cleaning up expired or deleted backup data. It is the preferred first step before making storage expansion decisions.
After a full DP4400 installation, including ESXi and virtual appliances, you log into the vSphere Web Client and find the Avamar VM is not responding.
What should you do FIRST to troubleshoot?
- A . Reinstall the ESXi hypervisor
- B . Reset the Avamar VM from the Data Domain GUI
- C . Open the VM console in vSphere and check for boot or network errors
- D . Reboot the entire DP4400 appliance
C
Explanation:
Accessing the VM console provides direct visibility into the VM’s status, such as boot failures or missing network configuration.
How can you configure email alerts in Avamar Administrator?
- A . Through dpnctl configuration
- B . Using the “Email Configuration” tool under the Tools menu
- C . By editing the smtp.conf file in the CLI
- D . From the DD System Manager
B
Explanation:
Email alerts are configured in Avamar Administrator under Tools > Email Configuration by specifying SMTP and recipient settings.
During a deployment, the customer requests a backup to be run for validation. The job completes, but when trying to restore the test file, it fails with a “data unavailable” message.
What is the MOST LIKELY cause?
- A . The backup was not assigned to the correct storage unit
- B . The restore job used the wrong DD Boost credentials
- C . The backup failed silently due to incorrect schedule
- D . The file system on the client was excluded from backup policy
D
Explanation:
If a path or file is not included in the backup selection or is explicitly excluded, it will not be available for restore, even if the job appears successful.
