D-PDD-DY-01 sample questions

Question 1

When performing a site readiness assessment for a new PowerProtect Data Domain appliance with two expansion shelves, what is the primary reason for calculating total U-space required before deployment?

Accepted Answer

To ensure sufficient contiguous rack space is available to allow for correct physical placement, thermal flow, and SAS cabling limitations.

Answer

To determine if the data center floor tiles can safely support the localized weight of the entire configuration.

Answer

To calculate the total required BTU/hr output for the data center HVAC systems.

Answer

To accurately provision the number of required Top-of-Rack (ToR) network switch ports for the management interfaces.

Question 2

A deployment engineer is reviewing the environmental requirements for a new PowerProtect DD appliance. The data center currently provides 208V AC power, but the customer only provisioned standard 15A circuits.

What is the most likely consequence if the deployment proceeds without correcting the power provisioning?

```

Accepted Answer

The circuits may trip under heavy load during backup windows or disk rebuilds, leading to unexpected hard shutdowns and potential data corruption.

Answer

The appliance will automatically downclock its CPU and disable expansion shelf SAS ports to stay within the 15A power envelope.

Answer

The system will operate normally but will issue continuous critical alerts regarding non-redundant power supplies.

Answer

The DD OS installation wizard will detect the lower amperage via the iDRAC sensors and refuse to complete the initial configuration.

Question 3

Which TWO actions must a deployment engineer perform when reviewing the installation checklist and verifying service tags before unpacking the PowerProtect Data Domain appliance? (Select TWO)

Accepted Answer

Verify that the physical service tags on the shipping boxes match the service tags listed on the customer's sales order and packing slip.

Accepted Answer

Confirm that all prerequisite components listed on the installation checklist (such as rail kits, power cords, and network cables) are present.

Answer

Register the service tags manually in DD System Manager before physically racking the appliance.

Answer

Flash the system BIOS to the latest version using the service tag to download the correct firmware package.

Answer

Connect the appliance to a temporary network to validate the service tag via Dell SupportAssist.

Question 4

True or False: The pre-deployment site readiness assessment should exclusively focus on the physical rack space and power availability, as network prerequisites can be addressed during the post-deployment phase.

Accepted Answer

False

Answer

True

Question 5

A financial institution is preparing for the deployment of a new PowerProtect DD series appliance to serve as their primary backup target. The deployment engineer is conducting the pre-deployment site readiness assessment.

The customer states they have exactly 4U of contiguous rack space available in Rack A, and 6U available in Rack B (which is 15 meters away). The order consists of one 2U head unit and two 2U expansion shelves. The customer insists on placing the head unit in Rack A and the expansion shelves in Rack B due to PDU capacity limits in Rack A.

Which of the following is the BEST technical response the engineer should provide regarding this deployment plan?

Accepted Answer

The plan is unacceptable because standard passive SAS cables have strict length limitations (typically 3 to 5 meters) and cannot span the 15-meter distance between the racks.

Answer

The plan is acceptable; however, active optical SAS cables must be ordered to support the 15-meter distance between Rack A and Rack B.

Answer

The plan is acceptable as long as both Rack A and Rack B share the same management VLAN for the iDRAC connections.

Answer

The plan is unacceptable because the head unit and expansion shelves must share the exact same physical PDU to ensure synchronized power-on sequencing.

Question 6

During the pre-deployment checklist review, a customer asks why you need to verify the availability of specific network port speeds (e.g., 10GbE or 25GbE) on their Top-of-Rack switches prior to unboxing the hardware.

What is the most accurate technical justification?

Accepted Answer

To confirm compatibility with the specific Network Daughter Card (NDC) or PCIe NICs ordered with the appliance, avoiding delays caused by mismatched transceivers or cabling.

Answer

To ensure the appliance's management interface (ethMa) can negotiate properly, as it requires a minimum of 10GbE to function.

Answer

To calculate the expected deduplication ratio, which is directly correlated to the network bandwidth available during backups.

Answer

To ensure the SAS expansion shelves can communicate with the network switches, which require 25GbE for optimal performance.
