The EXIN EPI CDCS exam focuses on three primary subject areas: the data centre life cycle and standards, data centre design and implementation, and environmental considerations for data centres.

In this section, candidates will be tested on their understanding of the overall life cycle of a data centre, as well as the industry standards that govern the design and operation of these facilities.

Data Centre Life Cycle: Understanding the planning, design, and operational phases of a data centre.

Standards and Rating Levels: Familiarity with the various standards such as Uptime Institute’s Tier Standards and other globally recognized rating levels, which help define performance and redundancy levels in data centres.

This is the most comprehensive part of the exam, focusing on the intricacies of data centre design and implementation. The areas covered include:

Building Considerations: Understanding site selection, space allocation, and building materials that affect data centre functionality.

Advanced Raised Floor/Suspended Ceiling Systems: Examining the advantages of these systems for optimal air distribution and cabling.

Power Management: Designing advanced power distribution systems that ensure high availability and energy efficiency.

Electromagnetic Field Management: Implementing strategies to minimize electromagnetic interference that can affect data centre performance.

Cooling Solutions: Designing advanced cooling systems to ensure optimal temperature and humidity control for sensitive equipment.

Fire Protection: Implementing advanced fire suppression systems to safeguard the facility.

Network Cabling Systems: Understanding the design of scalable and efficient cabling infrastructures for high-speed data transmission.

The final part of the exam covers environmental factors that impact the performance of data centres, including:

Environmental Specifications: Understanding the impact of temperature, humidity, and airflow within the data centre.

Contamination Control: Learning methods for minimizing dust and other airborne contaminants that can damage sensitive equipment.

Data Centre Efficiency: Exploring strategies to reduce energy consumption while maintaining high performance.

1. What should be considered when installing overhead data cabling?

A.To maintain minimum separation from power and ensure that the fire detection and suppression systems are not hindered.

B.Copper data cabling should not be placed in metal cable trays.

C.Optical fiber cabling should always be positioned on top of the copper cabling in the same cable tray to avoid damage to the sensitive optical fiber.

D.All cabling should make sharp bends directly into the rack to avoid usage of additional space and blocking the airflow on top of the rack.

Answer: A
