NEW QUESTION # 35
A customer uses a backup application to back up data to a Dell PowerProtect Data Domain appliance.
In their environment, they require:
* Dedicated SAN traffic
* No backup traffic on the production IP network
Which connectivity option should the implementation engineer configure?
Answer: A
Explanation:
Comprehensive and Detailed Explanation From PowerProtect Data Domain Deploy Dell PowerProtect Data Domain supports DD Boost over Fibre Channel (DFC), which enables compatible backup applications to transfer backup and recovery data directly across a dedicated Fibre Channel storage area network (SAN). This architecture separates backup data movement from the production Ethernet network, meeting the customer's requirements for storage traffic isolation.
The Dell NetWorker and Data Domain Boost Integration Guide confirms that DD Boost devices support data transport over both Ethernet IP networks and Fibre Channel SAN environments. It also recommends using SAN interfaces for backup operations in Fibre Channel deployments.
Dell India+1
During deployment, the engineer must enable DD Boost over Fibre Channel, verify Fibre Channel connectivity, configure initiator access groups, and ensure that the backup application supports the DFC transport mechanism. Appropriate SAN zoning, compatible host bus adapters (HBAs), and correctly presented DD Boost devices are necessary.
Although backup payloads traverse the Fibre Channel fabric, Ethernet connectivity remains necessary for management and certain control operations.
Option A is incorrect because NFS operates over an IP network. Option C is incorrect because CIFS/SMB also uses IP networking. Option D is incorrect because the stated VTL over Ethernet configuration does not provide the required Fibre Channel transport.
Therefore, DD Boost over FC is the appropriate configuration for dedicated SAN-based backup traffic without transferring backup payloads across the production IP network.

NEW QUESTION # 36
A backup administrator has enabled the Retention Lock feature on their PowerProtect DD appliance. Over time, the administrator noticed an increase in file system utilization. Upon further investigation, the administrator discovered expired files are still present on the appliance.
What is the most likely reason for this issue?
Answer: B
NEW QUESTION # 37
An implementation engineer finds that Dell PowerProtect Data Manager fails to add the Dell PowerProtect Data Domain appliance. The connection test fails.
What three actions should be taken to resolve the issue? (Choose three.)
Answer: A,B,E
Explanation:
Comprehensive and Detailed Explanation From PowerProtect Data Domain Deploy Successful integration between Dell PowerProtect Data Manager (PPDM) and a PowerProtect Data Domain appliance depends on correctly configured storage services, management network connectivity, and valid authentication credentials. When the storage registration connection test fails, the engineer should investigate these dependencies before performing disruptive maintenance.
A). Check DD Boost service status: DD Boost provides optimized integration between Data Domain and supported backup applications. The engineer should verify that the service is enabled and operational. Dell's PowerProtect Data Manager connectivity troubleshooting documentation specifically identifies DD Boost availability as a validation requirement when a protection storage connection cannot be verified.
Dell US
B). Verify network connectivity: The engineer must confirm IP reachability, DNS resolution, routing, and firewall configuration between PPDM and Data Domain. Dell specifies TCP port 3009 as the default SSL management communication port used when adding protection storage.
Dell US
E). Check credentials: Incorrect passwords, expired credentials, or insufficient administrative permissions can prevent storage registration. The configured credentials must permit PPDM to authenticate and manage the protection storage system.
Option C is incorrect because upgrading DDOS is not an initial corrective action unless a documented compatibility or software defect requires it.
Option D is incorrect because restarting the appliance introduces unnecessary disruption and does not directly address the principal connection prerequisites.
Therefore, validating DD Boost service status, network connectivity, and authentication credentials provides the appropriate initial troubleshooting approach.

NEW QUESTION # 38
A security company requires limited access to its Dell PowerProtect Data Domain appliance. An account named PDAdmin is created with the limited-admin role. The user is able to log in to the Data Domain System Manager but receives an Access Denied error when trying to open an FTP session.
What is the cause of this error?
Answer: A
Explanation:
Comprehensive and Detailed Explanation From PowerProtect Data Domain Deploy Dell PowerProtect Data Domain Operating System (DDOS) implements role-based access control (RBAC) to regulate administrative operations and access to management services. The permissions assigned to an account determine which system functions and protocols it can use.
The Dell DD Operating System 7.13.1.30 Administration Guide explicitly states under Managing FTP Access:
Only users who are assigned the admin management role are permitted to access the system using FTP.
Dell Philippines
The limited-admin role allows authorized personnel to perform selected configuration, monitoring, and routine administrative tasks without receiving full administrative privileges. However, successful authentication to Data Domain System Manager does not grant unrestricted access to every management protocol.
In this scenario, PDAdmin can access the management interface because its assigned role permits that operation. The FTP connection is rejected because FTP access requires the admin management role.
Option B is incorrect because FTP access is not exclusive to the predefined sysadmin account. Option C is incorrect because the backup-operator role is intended for designated backup operations, not unrestricted administrative file transfers. Option D is incorrect because the user role primarily provides monitoring capabilities.
FTP must also be explicitly enabled and appropriately restricted. Dell recommends secure alternatives such as FTPS or SCP instead of unencrypted FTP.
Dell US
Therefore, the Access Denied error results from insufficient role privileges rather than failed authentication.

NEW QUESTION # 39
An administrator has retained snapshots for a single MTree and is trying to create a new one. An error message is received.
What is the reason for the failure?
Answer: D
Explanation:
The maximum number of snapshots allowed per MTree is 750. Warnings are sent when the number of snapshots per MTree reaches 90% of the maximum allowed number (from 675 to 749 snapshots), and an alert is generated when the maximum number is reached. To clear the warning, expire snapshots and then run the file system cleaning operation.
Note: To identify an MTree that is nearing the maximum number of snapshots, check the Snapshots panel of the MTree page regarding viewing MTree snapshot information.
