Preparation Tips
Successful candidates combine conceptual understanding with hands-on practice. Reviewing measured skills and working through scenario-based questions is strongly recommended.
Practice Questions for D-PST-MN-A-01 Exam
The following practice questions are designed to reinforce key D-PST-MN-A-01 exam concepts and reflect common scenario-based decision points tested in the certification.
Question#1
A Storage Administrator identifies a failed Power Supply Unit (PSU) on Node B via the PowerStore Manager UI. The administrator orders a replacement CRU and prepares to hot-swap the unit.
PowerStore Manager > Hardware > Appliances > [Appliance] > Components > Power Supplies
- Node B, PSU 0: Faulted
- Node B, PSU 1: Healthy
Which mandatory operational requirement must be verified to safely perform this hot-swap CRU replacement without causing a node failure?
A. The svc_node shutdown command must be issued to Node B using the PowerStore service CLI to isolate the electrical plane prior to PSU removal.
B. The SAS cables connecting the node to the expansion enclosures must be temporarily disconnected to prevent electrical grounding loops.
C. Verify the surviving PSU (PSU 1) shows solid green AC/DC LEDs, confirming it can sustain the node's full load during the swap.
D. The cluster must be placed into a temporary Maintenance Mode to suppress spurious power-loss alerts during the extraction.
Question#2
What is the primary architectural rationale for strictly segregating and distinctly labeling the 1GbE Base-T management ports from the high-speed Ethernet (e.g., 25GbE) iSCSI host connectivity ports on a PowerStore appliance?
A. To allow the PowerStore internal battery backup units (BBUs) to prioritize routing emergency power to the management interfaces during a facility outage.
B. To enable the system to automatically downgrade the iSCSI data traffic to 1GbE speeds if the primary 25GbE optical network switches experience a complete failure.
C. To prevent high-volume block storage data payloads from saturating the out-of-band management plane and causing PowerStore Manager to become unresponsive.
D. To ensure that the embedded module can bypass the system's hypervisor layer and write iSCSI traffic directly to the NVMe NVRAM cache drives.
Question#3
Cluster Health: Active Minor Warning regarding extreme NTP clock drift between Node A and Node B.
To successfully satisfy the checklist requirements and unlock the OS upgrade path, which THREE sequential remediation steps must the engineer execute? (Select all that apply.)
A. Execute a rolling node reboot manually via PSTCLI to force the operating system to clear its temporary staging partitions before uploading the new payload.
B. Export and delete the legacy support materials bundles from the appliance using PowerStore Manager to reclaim the required internal boot drive capacity.
C. Disable the SMTP and SNMP alert notifications temporarily so that the pre-upgrade checklist does not detect the active NTP drift warning during its secondary scan.
D. Reconfigure the cluster's external NTP server bindings to ensure time synchronization is accurate, thereby clearing the active logical warning alert.
E. Re-run the dedicated Health Check package to independently validate that both the capacity and the cluster health constraints have been fully and permanently resolved.
Question#4
A Technical Support Analyst is assisting a remote technician with a degraded PowerStore X-series node. The analyst establishes an SSH session to the appliance and issues a command to initiate a node power-off, but the command fails to execute.
> pstcli -d 10.0.0.50 -u admin -p Password123! node -id N1 power_off
Operation failed.
Error: The node cannot be powered off because the cluster is in a degraded state and powering off this node will cause data unavailability. (Event Code: 0x0100234)
Which TWO conditions would directly cause the PSTCLI to reject the power-off command with this specific error? (Choose 2.)
A. The system is actively downloading a PowerStoreOS software upgrade package in the background.
B. The appliance is experiencing a synchronized cache mirroring failure, and halting the node would result in uncommitted writes being lost.
C. The administrator account used for the PSTCLI session lacks the necessary Role-Based Access Control (RBAC) privileges to execute power actions.
D. The peer node (Node B) is currently offline or rebooting, meaning Node A is the only active path for storage I/
E. The Service LAN port is physically disconnected, preventing the management plane from signaling the hardware.
Question#5
A Dell Customer Success Engineer is guiding a customer through the initial diagnosis of a power anomaly on a PowerStore X-series cluster. The customer provides the current physical status of the appliance's rear components.
Component Status Indicators:
- Node A, Power Supply 0 (PSU0): AC Status LED is Solid Green
- Node A, Power Supply 0 (PSU0): Fault/DC LED is Solid Amber
- Node A, Power Supply 1 (PSU1): AC Status LED is Solid Green
- Node A, Power Supply 1 (PSU1): Fault/DC LED is Unlit
Which TWO statements accurately describe the diagnostic conclusion and the correct CRU replacement parameters for this scenario? (Choose 2.)
A. The solid amber LED indicates a critical failure within PSU0, requiring the unit to be replaced to restore full power redundancy.
B. The customer must use PSTCLI to gracefully power off Node A before attempting to physically extract the faulted PSU0.
C. The solid green AC Status LED on PSU0 indicates the component is healthy, and the amber LED merely signifies an active firmware update.
D. Power supplies are classified as CRUs and can be hot-swapped while the node continues running on the surviving healthy PSU1.
E. Because a power supply is classified as a FRU, the customer must immediately halt all I/O and wait for a certified Dell technician to arrive.
