The CDCS Exam is on trend but the main problem that every applicant faces while preparing for it is not making the right choice of the CDCS Questions.
EXIN EPI Certified Data Centre Specialist Sample Questions (Q20-Q25):NEW QUESTION # 20
The UPS of a data center with ANSI/TIA-942 Rating-4 is installed with the rectifier connected to power feed A and the bypass/reserve input connected to power feed B. To which feed will the UPS output be synchronized?
  • A. Feed B
  • B. Depends on UPS settings, as it can be set to either feed
  • C. Feed A
  • D. The UPS will not synchronize to any feed but use an internal clock
Answer: B
Explanation:
Modern UPS systems can synchronize their output to an external reference, either from the rectifier input (Feed A) or from the bypass input (Feed B). Synchronization ensures seamless transfer between normal and bypass operation.
The configuration depends on user or vendor settings:
* If synchronized to the bypass (Feed B), the UPS can quickly transfer to bypass during overload or failure.
* If synchronized to the rectifier (Feed A), the UPS maintains stable output independent of bypass conditions.
ANSI/TIA-942 does not mandate which feed the UPS must synchronize to, only that redundancy be maintained across feeds in a Rating-4 design. Manufacturers typically allow the choice depending on operational preference.
References: IEC 62040-3 (UPS Operational Modes), ANSI/TIA-942-B §6.2 (Electrical Redundancy).

NEW QUESTION # 21
The logical overview of the data center looks as pictured. To what TIA-942 Rating is this design made based on electrical only?

  • A. Rating - 3
  • B. Rating - 4
  • C. Rating - 1
  • D. Rating - 2
Answer: B
Explanation:
The electrical design shown in the diagrams represents a TIA-942 Rating-4 configuration. This design includes full redundancy and fault tolerance, as demonstrated by the dual power distribution paths from the utility supply to the critical loads. Each power distribution path is equipped with its own UPS, ensuring that the ICT equipment and mechanical equipment have uninterrupted power in case of any single point of failure.
Detailed Explanation:
A Rating-4 data center requires two independent power paths that are fully redundant and capable of supporting the load independently. In the diagrams:
There are dual feeds from the utility supply, each going through separate transfer switches and power distribution paths.
Both paths have backup sources (+1) and serve critical components through separate UPS systems, providing a completely redundant setup.
The design also includes redundant paths to the mechanical equipment and ICT equipment, which further indicates the fault-tolerant characteristics of a Rating-4 infrastructure.
This setup allows for concurrent maintainability and ensures that no single failure in power distribution or UPS can impact the data center's operation, which is characteristic of the highest Tier/Rated-4 classification.
EPI Data Center Specialist References:
EPI guidelines confirm that TIA-942 Rating-4 requires full redundancy and fault tolerance for electrical infrastructure, ensuring continuous operation even during maintenance or failure events. This design meets all those requirements, thus aligning with Rating-4 standards.

NEW QUESTION # 22
Smoke sensors must be installed in the computer room. What is the minimum density?
  • A. 1 per 40 m²
  • B. 1 per 25 m²
  • C. 1 per 10 m²
  • D. 1 per 5 m²
Answer: B
Explanation:
NFPA 75 (Standard for IT Equipment Protection) and NFPA 72 (Fire Alarm Code) recommend installing at least one smoke detector per 250 ft² (#25 m²) in IT rooms. This ensures early detection in high-value environments.
* A and B are far too dense, exceeding NFPA minimums.
* D is too sparse and would not meet early detection requirements.
Therefore, the correct standard density is 1 per 25 m².
References: NFPA 75 §5.4.3, NFPA 72 Table 17.6.3.5.1.

NEW QUESTION # 23
When designing a data center network, your company wants to minimize the number of network switches to manage.
What type of physical cabling layout would be the best choice?
  • A. It does not matter as the number of switches is not influenced by the physical cabling layout
  • B. ToR (Top of Rack) design
  • C. Star network design using coaxial cables
  • D. EoR (End of Row) design
Answer: D
Explanation:
An End of Row (EoR) design minimizes the number of network switches, as multiple racks can share a single switch at the end of a row, reducing switch counts and simplifying management. This design centralizes network switching to fewer points, which reduces the complexity and number of switches required compared to a Top of Rack (ToR) design, where each rack typically has its own switch.
Detailed Explanation:
In EoR designs, each row has a single network switch that handles the connections for all racks within that row. This reduces the number of individual switches needed and centralizes network management, which is ideal for minimizing equipment and simplifying infrastructure in the data center.
EPI Data Center Specialist References:
EPI promotes the EoR design as a way to reduce switch counts and streamline management in data centers. This configuration allows for easier scaling and maintenance while maintaining efficient network connectivity.

NEW QUESTION # 24
The pipes of a VESDA smoke detection system are installed at the air intake of the air conditioner inside the computer room.
Is this a good practice from an early smoke detection point of view?
  • A. No, it will give a longer reaction time for the smoke detection system and there might also be bypass airflow.
  • B. It depends on the type of gas-based fire suppression which will be installed.
  • C. No, the piping should be installed at the air exhaust of the air conditioner, as there can also be a fire inside the air conditioner itself.
  • D. Yes, as this reduces the amount of piping to be installed in the data center, as all air will go through the air conditioner.
Answer: A
Explanation:
For optimal early smoke detection in a data center, it is crucial that the Very Early Smoke Detection Apparatus (VESDA) system be installed at locations where smoke will be detected as soon as it appears. Positioning the VESDA pipes at the air intake of the air conditioner inside the computer room is not ideal. This placement could result in a delayed detection response and the potential for bypass airflow to occur, which would impede the system's ability to detect smoke effectively.
Detailed Explanation:
When VESDA pipes are installed at the air intake, the detection system relies on the smoke to be drawn into the air conditioning unit before detection can occur. This setup increases the reaction time as the smoke has to travel through the intake and get processed by the air conditioner. Furthermore, bypass airflow-a phenomenon where not all the air containing smoke particles passes through the VESDA pipes-could also delay or even prevent the system from detecting smoke early.
Ideally, VESDA pipes should be positioned where smoke is likely to accumulate first, such as near the ceiling or in the return airflow path to detect smoke at the earliest possible stage. This ensures that the detection system can quickly trigger alarms, providing more time to address potential fire hazards.
EPI Data Center Specialist References:
EPI Data Center Specialist training highlights that smoke detection should prioritize early response capabilities to maximize safety. The preferred installation for VESDA pipes is generally at points where smoke would naturally accumulate, rather than relying on air conditioning intakes where airflow can vary and delay detection. In their course materials, EPI emphasizes minimizing reaction time and reducing the impact of airflow dynamics on smoke detection efficiency.
