DCDC-004 Exam Areas at a Glance

The largest section is Concept Planning and Analysis, which represents 30% of the exam. Candidates should spend significant time reviewing needs assessment, site selection, risk analysis, feasibility reporting, utility availability, growth planning, and financial implications.

Concept Planning and Analysis

Exam Weight: 30%

This is the most heavily weighted area of the DCDC-004 exam. It focuses on the early planning stage of a data center project. Candidates must understand how to conduct a needs assessment, identify client objectives, determine operational requirements, evaluate data center models, and assess whether a cloud, colocation, on-premises, or other model is appropriate.

Key topics include:

• Conducting client needs assessments
• Determining operational and availability requirements
• Evaluating cloud, colocation, and on-premises models
• Identifying future growth and project phasing
• Reviewing shell space and expansion planning
• Conducting site surveys and site research
• Evaluating natural environment risks
• Reviewing utility environment factors such as power, water, gas, telecommunications, and cost
• Understanding financial implications and tax incentives
• Developing feasibility reports

This domain is important because poor planning can create long-term problems in capacity, resiliency, cost, sustainability, and operational performance.

Architectural, Mechanical, and Electrical Systems

Exam Weight: 20%

This area focuses on the physical facility systems that support the data center. Candidates should understand how architectural space design, mechanical systems, and electrical systems affect the overall data center design.

The architectural and space design portion requires candidates to apply client requirements and feasibility analysis to create functional layouts. This includes planning IT equipment space, support areas, personnel requirements, security areas, and adjacencies.

Mechanical systems include utility considerations such as water use, fuel storage, gas, sewer, and stormwater. Electrical systems include medium-voltage service, underground or overhead utility delivery, backup power, distribution systems, and voltage criteria. A DCDC candidate must know how to coordinate these requirements with engineers to ensure the design supports the client’s intent.

IT, Ancillary Systems, and Communications Connectivity

Exam Weight: 20%

This domain covers the technology and support systems inside the data center. Candidates should understand how IT equipment, storage, servers, networks, fire protection, physical security, building automation systems, and communications connectivity affect the detailed design.

Key areas include:

• Network, storage, and server requirements
• Cabinets, racks, SAN, standalone equipment, and network security
• Fire protection systems
• Physical security systems
• Building automation systems
• Fiber, copper, pathways, and communications requirements
• Coordination with RCDD professionals and other discipline designers

This section requires cross-discipline thinking. A data center design consultant must coordinate IT requirements with architectural, electrical, mechanical, security, and communications teams to ensure the facility functions as a complete system.

Data Center Operations and Maintenance Assessment

Exam Weight: 10%

This section focuses on assessing the current state and ongoing performance of a data center. Candidates must understand how to evaluate operational efficiency, capacity, growth potential, performance, utilization, utility costs, physical security, maintenance operations, documentation, and safety procedures.

Important topics include:

• Conducting optimization studies
• Assessing mechanical, electrical, and ancillary system conditions
• Reviewing efficiency and capacity
• Evaluating aging technologies and refresh needs
• Assessing utilities and operational costs
• Reviewing physical security
• Evaluating maintenance operations and procedures
• Reviewing documentation such as commissioning reports, logs, and DCIM records
• Assessing safety procedures such as lockout/tagout
• Developing assessment reports

This domain is practical because many DCDC professionals work not only on new data centers, but also on upgrades, audits, optimization projects, and operational assessments.

Security Assessment

Exam Weight: 10%

Security is a critical part of data center design. This domain validates the ability to support threat assessments, security audits, countermeasure planning, and disaster recovery design recommendations.

Candidates should understand how to:

• Manage threat assessments
• Identify threat frequency and impact
• Participate in security audits and building inspections
• Verify audit findings against security objectives
• Identify physical, electronic, and organizational countermeasures
• Coordinate cost-benefit or feasibility analysis
• Translate disaster recovery requirements into recovery design recommendations

This area is important because data centers house mission-critical systems. Physical security, electronic security, operational controls, and recovery planning must be considered as part of the full design process.

Construction Administration and Commissioning

Exam Weight: 10%

The final exam area focuses on the project execution and validation phases. Candidates should understand how a data center consultant supports the bid process, construction coordination, project closeout, pre-commissioning, commissioning planning, and commissioning execution.

Construction administration topics include:

• Assisting with bid process and award
• Coordinating with clients and contractors during construction
• Supporting project closeout activities

Commissioning topics include:

• Supporting pre-commissioning activities
• Verifying commissioning tests against design requirements
• Assisting with commissioning plan development
