How the Seven Domains Fit Together
The Dell Cloud Infrastructure Design 2023 exam (D-CI-DS-23) is a design exam, not an administration exam. The blueprint published by Dell Technologies walks through the life of a cloud infrastructure design engagement: you frame the problem, gather and analyze requirements, choose an architecture approach, layer on management and application platforms, and extend the design across clouds. Read in order, the seven domains are essentially a design workflow.
That framing matters for how you study. Candidates who treat each domain as an isolated list of products tend to struggle with scenario questions, because a design question rarely tests one domain in a vacuum. A question about a hybrid design may quietly depend on a requirement you were supposed to extract from collected data (Domain 2) and on the trade-offs between building and buying (Domains 3 and 4). If you want a broader orientation first, our overview What Is D-CI-DS-23? covers the credential at a high level, and this article goes deeper on the blueprint itself.
The Weight Map: Where the Points Live
Dell publishes approximate question-distribution weights for each domain. They are approximate, so expect some drift on any given exam form, but they are the best guide to where your hours should go.
| Domain | Name | Approx. Weight |
|---|---|---|
| 1 | Introduction to Cloud Design and Design Parameters | 10% |
| 2 | Data Collection and Analysis | 12% |
| 3 | Architecting a Do-It-Yourself Solution | 25% |
| 4 | Architecting a CI / HCI Solution | 18% |
| 5 | Cloud Management Platform | 10% |
| 6 | Hybrid Cloud and Multi Cloud | 15% |
| 7 | Application Development and Deployment Platform | 10% |
Two observations stand out. First, the three architecture-oriented domains (3, 4, and 6) together account for 58% of the exam. Second, the four "supporting" domains (1, 2, 5, and 7) are individually smaller but add up to 42%, which is far too much to skip. A candidate who masters only the big three and bluffs the rest is giving away close to half the exam.
Domains 1 and 2: Design Parameters and Data Collection
Domain 1: Introduction to Cloud Design and Design Parameters (10%)
What this domain establishes
This is the vocabulary and framing layer. Expect questions that test whether you understand what a cloud design has to account for before any architecture is chosen.
- Core cloud design concepts and the parameters that constrain a design
- How requirements, constraints, assumptions, and risks differ and why each is recorded
- How design parameters influence later architecture choices
Do not dismiss this domain because it sounds introductory. Its concepts reappear everywhere else. When a later question asks you to pick between two architectures, the right answer usually turns on a design parameter you were supposed to have internalized here.
Domain 2: Data Collection and Analysis (12%)
What this domain establishes
Design quality depends on input quality. This domain covers gathering information about the existing environment and the business need, then analyzing it so that sizing and architecture decisions are defensible.
- What information to collect about workloads, capacity, and performance
- How to interpret collected data to derive requirements
- How analysis results feed sizing and platform selection
Scenario questions here often hand you a snippet of environment data and ask what it implies for the design. Practice reading raw inputs and translating them into design consequences rather than memorizing definitions. Our D-CI-DS-23 study guide shows how to build that habit into a full prep plan.
Domain 3: Architecting a Do-It-Yourself Solution (25%)
This is the heaviest domain by a clear margin: one quarter of the exam. A do-it-yourself (DIY) solution means assembling infrastructure from individual compute, storage, and networking components rather than buying an integrated system. The design burden, and therefore the exam burden, is on you to make every layer work together.
Topics to master
Expect to reason about each infrastructure layer and the interactions between them.
- Compute design: sizing, host configuration, and workload placement considerations
- Storage design: capacity, performance, and protection choices for the workload profile
- Network design: connectivity, bandwidth, and availability between components
- Availability, scalability, and recoverability as design qualities, not afterthoughts
- Where a DIY approach is justified versus where an integrated option fits better
The recurring skill is trade-off analysis. A DIY design gives flexibility and component-level choice but pushes integration, validation, and lifecycle complexity onto the design team. Strong answers acknowledge both sides and tie the choice back to stated requirements.
Domain 4: Architecting a CI / HCI Solution (18%)
The second-largest domain covers converged infrastructure (CI) and hyperconverged infrastructure (HCI). Where Domain 3 asks you to assemble components yourself, this domain asks you to design with integrated building blocks and understand what that changes.
Topics to master
The core question is how integrated systems alter design decisions compared with a DIY build.
- The architectural differences between CI and HCI models
- Scaling behavior: how capacity and performance are added in each model
- How sizing and workload fit differ from a component-by-component design
- Operational and lifecycle implications of integrated systems
- When requirements point toward CI or HCI instead of DIY
A reliable way to prepare is to build a side-by-side comparison of DIY, CI, and HCI across the same criteria: scalability, flexibility, integration effort, operational model, and fit for workload type. If you can fill that grid from memory and justify each cell, you are well prepared for the "which approach and why" style of question that this blueprint rewards.
Domains 5 and 7: Management Platform and Application Platform
Domain 5: Cloud Management Platform (10%)
What to understand
A cloud is more than hardware. This domain covers the software layer that makes infrastructure consumable and governable.
- The role of a cloud management platform in a design
- Self-service, automation, orchestration, and catalog concepts
- Monitoring, governance, and cost visibility as design requirements
Domain 7: Application Development and Deployment Platform (10%)
What to understand
This domain connects infrastructure to the applications it ultimately serves, including how application platforms influence infrastructure requirements.
- How application development and deployment platforms sit on top of the infrastructure design
- How platform choices change infrastructure expectations such as scale, speed, and automation
- Why infrastructure designers need to understand the application lifecycle
These two domains are easy to under-prepare because they feel adjacent to "real" infrastructure design. That is a mistake. At 10% each, together they carry as much weight as Domain 3 does by itself less five points. They also make good tie-breakers on a hard exam, because candidates who ignore them lose points that are comparatively cheap to earn.
Domain 6: Hybrid Cloud and Multi Cloud (15%)
The third-largest domain extends the design beyond a single environment. Hybrid cloud combines private infrastructure with public cloud services; multi cloud spans more than one public provider. The design problems change once workloads, data, and operations cross environment boundaries.
Topics to master
Think in terms of what moves, what stays, and what connects them.
- The distinction between hybrid cloud and multi cloud models and the drivers for each
- Workload placement: which workloads suit which environment
- Connectivity, data mobility, and consistency of management across environments
- Security, governance, and cost considerations introduced by distribution
- How to extend a Domain 3 or Domain 4 design into a broader hybrid architecture
Key Takeaway
Hybrid and multi cloud questions are rarely about vocabulary alone. They test whether you can justify placement and connectivity decisions against a stated business requirement. Practice explaining why a workload belongs where it does, not just naming the model.
Sequencing the Domains in Your Prep
Generic study schedules are everywhere, so here is one tied specifically to the D-CI-DS-23 blueprint. The logic is to follow the design workflow, then spend your heaviest effort where the weights are greatest, then close with the cross-domain integration that scenario questions demand.
Foundations and data
- Domain 1: design parameters, requirements versus constraints
- Domain 2: data collection and analysis, sizing inputs
The heavyweight domain
- Domain 3: compute, storage, and network design for DIY solutions
- Write out trade-offs between flexibility and integration effort
Integrated approaches
- Domain 4: CI and HCI architecture, scaling, and fit
- Build your DIY versus CI versus HCI comparison grid
Platforms and clouds
- Domain 5 and Domain 7: management and application platforms
- Domain 6: hybrid and multi cloud placement and connectivity
Integration and rehearsal
- Timed practice sets mixing all seven domains
- Revisit weak areas, weighting review time by domain percentage
If you have less time, compress by merging weeks but keep the order: data before architecture, architecture before cloud extension. When you are ready to test yourself under realistic conditions, the D-CI-DS-23 practice tests let you drill scenario-style questions across all seven domains. For a printable recap in the final days, the D-CI-DS-23 cheat sheet condenses the must-know facts.
Exam Logistics That Shape How You Study
The published format affects strategy as much as the content does. Here is what Dell and its testing provider publish for this exact exam code.
- Duration: 90 minutes.
- Languages: English and French.
- Delivery: Pearson VUE, either at a test center or through proctored OnVUE online delivery.
- Results: Computer-scored results are provisional pending Dell review.
- Not published: The retrieved exact-code sources do not state the question count, the passing score, or a pass rate.
Because the passing score is not published, resist any site that claims to know the exact cut. For the honest picture of what is and is not known, see our pages on the D-CI-DS-23 passing score and pass rate. With 90 minutes on the clock and scenario-driven questions, pacing practice is worthwhile: read the scenario for requirements first, then evaluate the options against them.
Registration, vouchers, and retakes
Pearson's U.S. voucher store lists the general Dell certification voucher at USD 230, and the voucher expires 12 months after purchase. Voucher expiry is separate from credential validity, so buying early does not shorten how long your certification is recognized, but it does start a clock on when you must sit the exam. Our certification cost breakdown covers the full pricing picture.
If you test online through OnVUE, you need a passed system test, a government photo ID that matches your registration, and a private room without books or notes. Failing a first attempt means a 7-day wait before retaking; later failures carry a 14-day wait. Those waits are short, but each attempt costs a voucher, which is the practical reason to prepare thoroughly before scheduling.
Where the Credential Gets Used
D-CI-DS-23 is a Dell Technologies Proven Professional exam, and its design emphasis points to roles where someone translates business requirements into infrastructure architecture. Typical examples include solution architects, pre-sales and systems engineers, infrastructure consultants, and design-oriented members of IT operations teams at Dell customers and partners. Credential status is managed in CertTracker, and recognition follows current Dell requirements, including revised exams when Dell requires them, so keep an eye on Dell's policy documents rather than assuming a credential is permanent.
If you are weighing the investment, our analyses of whether the certification is worth it and D-CI-DS-23 jobs explore the career side without relying on invented figures. Candidates unsure about difficulty can start with how hard the D-CI-DS-23 exam is.
Key Takeaway
Allocate review time roughly in proportion to the published weights, but never at zero for any domain. The 10% domains are individually small and collectively decisive.
