A deployment engineer is cabling a PowerProtect DD system that includes a head unit and three DS60 expansion shelves. To ensure high availability and optimal performance, the engineer must follow strict SAS cabling topology rules.
Which of the following represents the correct SAS cabling methodology for this configuration?

Correct answer: C
PowerProtect DD uses a redundant SAS multipath topology. Shelves are daisy-chained together (Link Control Card A to LCC A, LCC B to LCC B). The head unit connects to the beginning of the chain (first shelf) via one HBA port, and connects to the end of the chain (last shelf) using another HBA port, creating a highly available loop.

When connecting power to a newly racked PowerProtect DD head unit and its expansion shelves, what is the best practice for ensuring power redundancy?
Show answer details
Correct answer: B
To achieve true power redundancy, components with dual power supplies must have their power cords split across two distinct Power Distribution Units (PDUs), which should ideally be fed by independent electrical circuits (e.g., A/B power feeds).

A deployment engineer is finalizing the network cabling on a PowerProtect DD appliance. The customer requires redundant connections for data ingest and a separate out-of-band management interface.
Which TWO network connections are standard requirements during this phase? (Select TWO)
Show answer details
Correct answer: A, C
The dedicated iDRAC (Integrated Dell Remote Access Controller) port provides out-of-band hardware management, console access, and environmental monitoring, which is a standard requirement for enterprise deployments.
To provide redundancy and high availability for data ingest (backups), multiple network interfaces should be cabled to redundant switches, often utilizing link aggregation (LACP) or active/passive failover configurations.

To perform the initial configuration of a new PowerProtect DD appliance, a deployment engineer connects a laptop to the micro-USB/DB-9 serial console port on the head unit.
What are the correct terminal emulation settings required to establish a successful serial connection?
Show answer details
Correct answer: B
The standard serial console settings for Dell PowerProtect Data Domain appliances are 115200 baud rate, 8 data bits, no parity, and 1 stop bit (115200 8-N-1).
- 5
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?
Show answer details
Correct answer: B
Calculating U-space ensures that the head unit and expansion shelves can be mounted contiguously (or near each other) within the rack. This is critical because SAS cables have maximum length limits, and dispersing shelves across distant racks would violate cabling topology rules and disrupt optimal thermal flow.
- 6
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?

Correct answer: C
Enterprise appliances like the PowerProtect DD often require higher amperage circuits (e.g., 30A or specific C13/C14, C19/C20 configurations) depending on the model and number of shelves. Using under-provisioned circuits risks tripping breakers during peak loads (like boot sequences, heavy I/O, or disk rebuilds), causing sudden power loss.
