- D-PSC-MN-01 is Dell's PowerScale Maintenance exam, split into four categories of roughly 25% each: Concepts, Maintenance, Installation, Implementation.
- No domain is weighted higher, so a weak area in any one of the four can cost you real points.
- Retake waits are seven days after a first failure and fourteen days after later failures.
- Cancel a test-center appointment less than 24 hours out and the fee is forfeited.
Identity and Scope: What This Cheat Sheet Covers
This page is a one-page-style review for a single credential: D-PSC-MN-01, Dell PowerScale Maintenance, part of the Dell Technologies Proven Professional program. It is offered in English and French and is aimed at implementation specialists, technical consultants and technical-support personnel who install, service and bring up PowerScale clusters.
A cheat sheet is only useful if every line on it is trustworthy, so this one is deliberately conservative. It contains the four official examination categories, the registration and retake mechanics that Dell and its test provider publish, and the version history that keeps candidates from studying the wrong exam. It does not contain invented pass rates, guessed question counts or recycled numbers from other credentials. If you want the long-form treatment of any topic below, the D-PSC-MN-01 study guide is the companion piece, and the What Is D-PSC-MN-01? overview covers the credential's purpose.
The Four-Domain Map at a Glance
Dell's published blueprint lists four categories, each carrying approximately 25% coverage. No category has a higher published allocation. That is the single most important structural fact for planning: there is no "high-yield" domain to over-invest in and no "throwaway" domain to skip.
| Domain | Weight | What It Covers |
|---|---|---|
| PowerScale Hardware Concepts | ~25% | Architectural components, platform specifications, networking and management tools |
| PowerScale Hardware Maintenance | ~25% | Preliminary maintenance tasks, node preparation, FRU/CRU requests |
| PowerScale Hardware Installation | ~25% | Planning, site preparation, racks, subcomponents, node cabling |
| PowerScale Implementation | ~25% | Cluster creation, joining nodes, alternative accessories/configurations, upgrade activities |
One caution: these four lines reproduce official examination categories, not training-course modules. Dell's course titles and the exam's categories do not map one-to-one, so study to the categories above. For a deeper walk through each, see the complete guide to all four content areas.
Domain 1 Facts: Hardware Concepts
PowerScale Hardware Concepts (~25%)
This is the vocabulary domain. Every other domain assumes you can name components correctly and explain how they fit together.
- Architectural components of a PowerScale node and a cluster
- Platform specifications: be able to tell node platforms apart and know what distinguishes them
- Networking: how nodes connect to each other and to client networks
- Management tools used to monitor and administer the hardware and cluster
The trap in this domain is shallow recognition. Knowing that a component exists is not the same as knowing its role relative to the node, the cluster back-end and the client-facing network. Expect questions that ask you to reason about which component or network a scenario involves, not merely to define a term. The What Does D-PSC-MN-01 Stand For? page is a quick refresher if you are still orienting to the naming conventions.
Domain 2 Facts: Hardware Maintenance
PowerScale Hardware Maintenance (~25%)
This domain is the namesake of the exam and the one most tied to day-to-day field and support work.
- Preliminary maintenance tasks performed before touching hardware
- Node preparation prior to service activity
- FRU and CRU requests: know the difference between field-replaceable and customer-replaceable units and how a replacement is requested
Study this domain as a sequence, not a list. Maintenance work has an order of operations: confirm what is wrong, prepare the node, request the correct part, then replace it. Questions tend to reward candidates who understand why a preparatory step precedes a replacement rather than those who memorized the part name. Candidates in technical-support roles often find this domain intuitive and the next one less so, which is worth knowing when you plan your own gaps.
Domain 3 Facts: Hardware Installation
PowerScale Hardware Installation (~25%)
The physical-world domain: everything that happens between a delivered box and a powered, cabled node.
- Planning and site preparation requirements
- Racks and rack-mounting considerations
- Subcomponents installed within or alongside nodes
- Node cabling for the cluster's internal and external connectivity
Dell's recommended reading includes the PowerScale Node Site Preparation and Planning Guide, and that is a strong hint about where this domain lives. Site preparation questions are fact-sensitive: power, space and environmental requirements are the kind of detail that is far easier to retain if you have read the planning document rather than a summary of it. Cabling questions reward a clear mental picture of which ports serve which network, so sketch a simple node-to-network diagram from memory as a self-test.
Domain 4 Facts: Implementation
PowerScale Implementation (~25%)
The software-meets-hardware domain, where a collection of nodes becomes a working cluster.
- Cluster creation: the first node and the initial configuration
- Joining additional nodes to an existing cluster
- Alternative accessories and configurations
- Upgrade activities, including how upgrades are planned and carried out
Dell's supplementary PowerScale Upgrades training and the OneFS Upgrade Planning and Process Guide both point at the upgrade portion of this domain, so do not treat upgrades as an afterthought. Pair cluster creation and node-joining in your study: they are two sides of the same lifecycle, and scenario questions often ask what must be true before a node can be added or what changes once it has been.
Registration and Retake Rules You Can Verify
Dell's proctored skills-certification exams are delivered by Pearson VUE, either at a testing center or through OnVUE remote proctoring. Credential records are managed in CertTracker, and digital badges are issued through Credly. Dell treats these proctored exams as distinct from its separate, unproctored practice tests.
| Rule | What the Published Policy Says |
|---|---|
| Delivery | Pearson VUE testing center or OnVUE remote proctoring |
| Retake after first failed attempt | Wait seven days |
| Retake after second or later failure | Wait fourteen days |
| Test-center cancellation | Less than 24 hours before the appointment forfeits the fee |
| Credential records and badges | CertTracker for records; Credly for digital badges |
Two practical consequences follow. First, the retake waits make a failed attempt expensive in calendar time even before you count the fee, so treat your first booking as a real attempt rather than a diagnostic. Second, the 24-hour cancellation rule means you should lock your date only when your preparation is on schedule. For fee amounts and what is bundled, see the certification cost breakdown, and for scheduling logistics see the exam dates and scheduling guide.
Key Takeaway
The numbers you can safely put on a one-page cheat sheet are the four ~25% domains, the seven- and fourteen-day retake waits, and the 24-hour cancellation rule. Anything else about timing, scoring or price should come from your live booking page, not memory.
The Version Boundary: Retired Exam vs. Current Exam
This is the most common way candidates get misled. D-PSC-MN-01 launched on June 21, 2024, immediately after its predecessor, D-PSC-MN-23, retired on June 20, 2024. The retirement notice for the older exam still circulates online, and much of its content describes the retired exam, including its question count, duration, passing threshold, domain percentages and validity statements.
None of those older values should be carried over to D-PSC-MN-01. Likewise, do not substitute PowerScale Deploy or Design exam material for this one; they are different exams with different scopes. Our passing score page explains why a specific cut score is not stated here and how to find the figure that applies to your attempt, and the pass rate discussion explains why published success percentages should be treated skeptically.
The Reference Shelf Dell Recommends
Dell's recommended-training document for D-PSC-MN-01 lists May 2024 versions of the four core training courses plus supplementary PowerScale Upgrades training. It also names recommended references. These are preparation resources, not additional official domains and not an independently exhaustive exam outline.
- OneFS 9.8.0.0 Web Administration Guide: management tooling and cluster administration concepts
- PowerScale Supportability and Compatibility Guide: what works with what, relevant to platforms, accessories and upgrades
- PowerScale Node Site Preparation and Planning Guide: the natural companion to the Installation domain
- PowerScale OneFS Best Practices: configuration guidance relevant to implementation decisions
- OneFS Upgrade Planning and Process Guide: the upgrade activities in the Implementation domain
Dell restricts unauthorized preparation materials and the disclosure of examination content under its Proven Professional policies. Avoid exam dumps and any site that claims to reproduce real test questions; they put your credential at risk. Likewise, independent study material, including ours, is not Dell-authorized instruction, so use Dell's own training and references as your primary source and treat third-party practice as a supplement. Our training overview explains how to approach the official courses.
Scheduling the Four Domains
Because all four domains weigh the same, the useful scheduling question is not "which matters most" but "which depends on which." Concepts should come first because every other domain assumes that vocabulary. Installation and Maintenance both lean on hardware knowledge and are best studied while the Concepts material is fresh. Implementation comes last because upgrades and cluster-joining draw on everything before them. Adjust the order if your daily work already covers one area.
Hardware Concepts
- Name every architectural component and its role
- Compare platform specifications side by side
- Map the back-end and client network paths
Hardware Installation
- Read the Site Preparation and Planning Guide
- Practice describing rack, subcomponent and cabling steps from memory
Hardware Maintenance
- Walk through the maintenance sequence from preliminary tasks to replacement
- Drill the FRU versus CRU distinction and request flow
Implementation and Review
- Cluster creation, node joining and upgrade planning
- Take an unproctored practice test and revisit your weakest domain
If you are unsure how much total time you need, the difficulty guide discusses how background experience changes the calculation, and you can test your readiness against our D-PSC-MN-01 practice tests as the final week approaches.
Frequently Asked Questions
None. Each of the four published categories carries approximately 25% coverage, and no category has a higher published allocation. Plan your preparation evenly rather than favoring Maintenance because of the exam's name.
No. D-PSC-MN-23 retired on June 20, 2024, and its question count, duration, passing threshold and domain percentages describe the retired exam. Confirm current values for D-PSC-MN-01 on the booking page instead.
Seven days after a first failed attempt and fourteen days after a second or subsequent failure. Cancelling a test-center appointment less than 24 hours beforehand forfeits the fee.
Target roles include implementation specialists, technical consultants and technical-support personnel. The requirements page covers eligibility and prerequisites, and the jobs overview looks at where the credential is relevant.
No. Dell distinguishes its proctored Pearson VUE exams from its separate unproctored practice tests, and a practice bank's size says nothing about the live exam's item count. Use practice questions to find weak domains, not to predict exact exam content.
