Dell EMC Dell PowerProtect DD Deploy 2023 D-PDD-DY-23 Exam Practice Test

Answer : B

Virtual Synthetic Backups are an efficient method for consolidating full and incremental backups without moving large amounts of data. This method is particularly useful when restores are frequent because it reduces the time and resources required to create new full backups. Instead, it synthesizes a full backup from previous full and incremental backups, making the restore process faster and more efficient. This helps to optimize performance and minimize the strain on the backup system during frequent restores.

Answer : C

Each PowerProtect DD system can support up to two Cloud Tiers. Therefore, with three PowerProtect DD systems, the maximum number of Cloud Tiers is calculated as follows:

2 Cloud Tiers per PowerProtect DD system 3 PowerProtect DD systems = 6 Cloud Tiers total.

This configuration allows the administrator to utilize multiple cloud providers efficiently across the consolidated PowerProtect DD systems.

Answer : D

Persistent binding: Ensures that devices are consistently mapped to the same target IDs or LUNs, even after reboots or SAN changes. This is important for maintaining stability and avoiding configuration issues in a SAN environment.

Port zoning: Limits the devices that can communicate with each other on the SAN by controlling access based on physical ports or World Wide Names (WWNs). This enhances security and reduces the potential for disruptions in the SAN by minimizing access to the VTL.

Answer : A

DD Retention Lock enforces data immutability, ensuring that critical data cannot be altered or deleted until its retention period expires. This feature is essential for regulatory compliance and data integrity in long-term storage.

Answer : A

The maximum backup speed of the PowerProtect DD Virtual Edition (DDVE) when utilizing DD Boost is 4.2TB per hour. DD Boost is a feature that enhances the speed and efficiency of data transfers between the backup application and the Data Domain appliance by performing deduplication operations closer to the source, thus reducing network traffic and improving throughput. DDVE's performance capabilities are optimized for virtualized environments, and the 4.2TB/h rate represents the upper limit under ideal conditions, maximizing data protection performance in virtual setups.

Answer : C

In a PowerProtect DD environment, Cloud Tier allows the integration of multiple cloud providers to optimize data storage and management. By supporting up to three cloud units, administrators can leverage various cloud services for backup and storage, enhancing flexibility and resource allocation while maintaining efficient data protection strategies.

Answer : A

The standard port for syslog monitoring over UDP is 514. This protocol is widely used for logging and monitoring networked devices, including PowerProtect DD, facilitating real-time monitoring and alerts.
