EXIN Certified Data Centre Professional (CDCP) Sample Questions (Q24-Q29):

NEW QUESTION # 24
What is a requirement of an FM200 (HFC-227) installation?

A. It is a high-pressure gas; therefore nozzles must be mounted with two brackets.
B. Install pre-action sprinklers in the same room as the FM200.
C. Install the gas containers (tanks) close to the data centre.
D. Drainage system under the raised floor.

Answer: A

Explanation:
FM200 (HFC-227) is a clean agent fire suppression system that uses a high-pressure gas to extinguish fires by reducing the oxygen concentration and absorbing the heat. FM200 is stored in cylinders at pressures of up to
42 bar (600 psi) and is released through nozzles into the protected area. Because of the high pressure, the nozzles must be mounted with two brackets to prevent them from moving or breaking during discharge. The brackets must be securely attached to the ceiling or wall and aligned with the nozzle outlet. The nozzle outlet must also be free of any obstructions that could affect the discharge pattern or distribution.

NEW QUESTION # 25
Which one of the following is the last stage in Stages of Combustion?

A. Visible Smoke
B. Incipient
C. Intense Heat
D. Flaming Fire

Answer: D

Explanation:
The last stage in stages of combustion is flaming fire, which occurs when the fuel vapors and oxygen are mixed in the right proportion and ignited by a flame or a spark. Flaming fire is characterized by visible flames, intense heat, and rapid oxidation. Flaming fire can cause severe damage to the data center equipment, personnel, and business continuity. Therefore, it is important to prevent or suppress flaming fire as soon as possible using appropriate fire detection and suppression systems.

NEW QUESTION # 26
The UPS vendor is offering the latest model of their UPS to you. The vendor indicates that the UPS is categorized as VFD class.
Is this UPS a fit for your mission-critical data centre?

A. No
B. Yes
C. Yes, but only if they install it with a 12-pulse rectifier.
D. Yes, but only if you oversize the battery bank with 10%.

Answer: A

Explanation:
A UPS (uninterruptible power supply) that is categorized as VFD class is not a fit for your mission-critical data centre, because it does not provide adequate protection against voltage and frequency variations. VFD stands for Voltage and Frequency Dependent, which means that the output voltage and frequency of the UPS depend on the input voltage and frequency. VFD UPSs are also known as offline, standby, or line-interactive UPSs. They typically switch to battery power only when the input power fails or goes beyond a certain threshold. However, this switching may cause a brief interruption or a transient in the output power, which can affect the performance and reliability of the ICT equipment. Moreover, VFD UPSs do not filter or regulate the input power, which means that they pass on any voltage or frequency fluctuations, harmonics, or noise to the output power. These power quality issues can also damage or degrade the ICT equipment and the data.
For your mission-critical data centre, you need a UPS that is categorized as VFI class, which stands for Voltage and Frequency Independent. VFI UPSs are also known as online, continuous, or double-conversion UPSs. They provide a constant and clean output power that is independent of the input power. VFI UPSs convert the input AC power to DC power, and then convert it back to AC power with the desired voltage and frequency. This double conversion process isolates the output power from the input power, and eliminates any power quality issues. VFI UPSs also have zero switching time, which means that they do not cause any interruption or transient in the output power when switching to battery power. VFI UPSs are designed to protect the ICT equipment and the data from any adverse effects of voltage and frequency variations, and to ensure the highest level of availability and reliability.

NEW QUESTION # 27
Which one of the following is a core objective of a Business Value in an organization?

A. None of the above
B. Reducing the Deficit
C. Reducing Costs
D. Increasing Sales

Answer: A

Explanation:
According to the EPI Data Centre Professional (CDCP®) Reference Materials, a core objective of a Business Value in an organization is to create value for customers and stakeholders1. This means delivering products or services that meet or exceed customer expectations, while also generating profits or benefits for the organization and its shareholders. Reducing costs, reducing the deficit, and increasing sales are possible ways to achieve this objective, but they are not the core objective itself.

NEW QUESTION # 28
The temperature and humidity values indicated on the display of the Computer room air conditioner unit are the values measured at which point?

A. It is the value measured at the intake of the air conditioner.
B. It is the value measured at the front of the rack of the aisle the air conditioner is situated.
C. It is the average value between the intake and exhaust (outlet) of the air conditioner.
D. It is the value measured at the exhaust (outlet) of the air conditioner.

Answer: A

Explanation:
According to the IBM document on temperature and humidity design criteria1, the temperature and humidity values indicated on the display of the computer room air conditioner unit are the values measured at the intake of the air conditioner. This is because the intake is where the air conditioner draws the air from the computer room and cools and dehumidifies it before sending it back to the computer room. The display shows the current conditions of the computer room air, which are used to adjust the cooling and dehumidifying operations of the air conditioner. The values measured at the exhaust (outlet) of the air conditioner are not displayed, as they are not relevant for the computer room environment. The values measured at the front of the rack of the aisle the air conditioner is situated are also not displayed, as they may vary depending on the distance and location of the rack. The average value between the intake and exhaust (outlet) of the air conditioner is not displayed, as it does not reflect the actual conditions of the computer room air or the air conditioner performance.
