NO.98 What needs to be configured when implementing LACP on a PowerProtect DD appliance to gain access to the underlying aggregated link connection?

NIC Teams

DD Boost Interface Groups

Virtual network interface

Physical network interface

Explanation: When implementing Link Aggregation Control Protocol (LACP) on a PowerProtect DD appliance, a virtual network interface is created to aggregate the physical interfaces into a single logical link.
This configuration is essential to enable LACP functionality, as it allows the system to balance network traffic effectively across multiple physical connections, enhancing redundancy and throughput. By aggregating these physical interfaces, the appliance can better handle high data volumes, providing stable and efficient access to the underlying network resources.
The virtual network interface manages the logical grouping, ensuring seamless failover and load balancing between the physical links that comprise the aggregated connection.

NO.99 A backup administrator is tasked with verifying the compression settings of a DDVE instance.
Which compression algorithm will be enabled by default?

gzfast

lzw

NO.100 What is a use case of BoostFS

To protect applications that do not support DD Boost

To increase DD Boost throughput

To enable snapshot on DD Boost data

To implement DD Boost over Fibre Channel

NO.101 A PowerProtect DD appliance with two expansion shelves is being installed in a customer-provided rack.
When cabling the controller to the shelves, what is connected to the host port on the last shelf in the chain?

Expansion port of the upstream shelf

Host port of the controller

Expansion port of the controller

Host port of the downstream shelf

In a PowerProtect DD system, when setting up expansion shelves, the cabling follows a specific sequence to ensure proper communication between the controller and the shelves. The host port on the last shelf in the chain is connected to the expansion port of the controller to complete the loop. This ensures that data flows correctly between the controller and all shelves in the chain.

NO.102 What is the maximum number of snapshots per MTree that can be stored on a PowerProtect DD?

750

100

128

Explanation: PowerProtect DD allows up to 750 snapshots per MTree, supporting efficient data protection and recovery with minimal impact on storage resources. This feature provides extensive backup versioning options for granular data recovery.

NO.103 The finance department requires unused PDFs older than 90 days to be tiered into Azure Blob Storage.
Which data movement policy is used to archive the files?

Recall

Age-based

App-driven

Age-range

NO.104 A company has SMT and VTL enabled on a PowerProtect DD appliance. They back up their data to virtual tape under a VTL pool named “finance”.
Where is the backup data stored on the PowerProtect DD appliance?

/data/col1/finance

/data/col1/<tenatname>/finance

/data/col1/<tenatname>/vtl/finance

/data/col1/vtl/finance

NO.105 What command is used to make a storage unit?

storage add tier active

ddboost storage-unit create <storage_unit>

filesys create

boostfs mount -storage unit

Explanation: The ddboost storage-unit create <storage_unit> command is used to create a storage unit specifically for DD Boost-enabled backups, facilitating direct backup operations with PowerProtect DD.

NO.106 When using CIFS from a PowerProtect DD system, what should be changed on a Windows machine?

SMBTimeout to 7200 seconds

SESSTIMEOUT to 3600 seconds

CIFSTimeout to 3600 seconds

SESSTIMEOUT to 7200 seconds

The SESSTIMEOUT setting controls the session timeout for CIFS (SMB) connections. Adjusting this value to 3600 seconds helps ensure that CIFS sessions stay active for a sufficient duration, preventing premature disconnections when the PowerProtect DD system interacts with the Windows machine. This can enhance the reliability and stability of CIFS-based backups and restores.

NO.107 A backup administrator is investigating the File System Log of their source DD9900. They noticed an error on the file system and quickly corrected the issue. However, 30 minutes after making the fix, the error status has not changed.
Why is the error still appearing in the File System Log?

System status messages are updated every 45 minutes

Corrected errors do not reappear in logs

System status messages are updated hourly

System status messages are only available through CLI

NO.108 What is the correct order for the DDOS Deduplication process?

Compress, Filter, Fingerprint, and Segment

Fingerprint, Segment, Filter, and Compress

Segment, Fingerprint, Filter, and Compress

Filter, Compress, Segment, and Fingerprint

NO.109 Which PowerProtect DD feature protects data from accidental or malicious deletion during its retention time?

Smart Scale

Retention Lock

Data Invulnerability Architecture

Encryption

NO.110 Which Linux distributions support BoostFS?

Raspbian, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server

Debian, SUSE Linux Enterprise Server, and CentOS

Red Hat Enterprise Linux, CentOS, and SUSE Linux Enterprise Server

CentOS, Red Hat Enterprise Linux, and Debian

BoostFS is compatible with several Linux distributions, and the listed options include:
Red Hat Enterprise Linux (RHEL): A widely used enterprise Linux distribution known for its stability and support.
CentOS: A community-supported distribution derived from RHEL, providing similar functionality and compatibility.
SUSE Linux Enterprise Server: Another enterprise-level distribution that is known for its performance and support for various applications.

NO.111 PowerProtect DD Test Simulator
You will need to use the PowerProtect DD Simulator to correctly answer question. The simulator allows you to navigate through the PowerProtect DD interface and configure many items. You will be scored on your ability to perform tasks, configure items, and gather information within the simulated environment.
Task
As an administrator, you observe that the PowerProtect DD does not free disk space even though the backup retention period expired a month ago.
Check the cleaning schedule. Set the default parameters: Start every Tuesday at 6:00 am. Set the throttle for scheduled cleaning to 50%. After setting the schedule, start cleaning manually and make sure the system resources are not used more than 30% for this cleaning.
When you have finished, continue to the next question.

See the solution in the explanation below.
Explanation:
To resolve the issue and set up the cleaning schedule and manual cleaning on your PowerProtect DD system, follow these steps based on the information provided:
Access the Cleaning Schedule Settings:
Go to File System Settings.
Navigate to the Cleaning tab.
2. Set the Cleaning Schedule:
Frequency: Choose Weekly.
At: Set the cleaning to start every Tuesday at 6:00 AM.
Throttle: Set the throttle to 50% for scheduled cleaning.
3. Manually Start Cleaning:
After setting the schedule, initiate the cleaning manually from the File System settings.
Set the manual cleaning throttle to 30% to ensure system resources are not overused during the process.
