EXIN Certified Data Centre Professional (CDCP) Sample Questions (Q55-Q60):NEW QUESTION # 55
What should be considered when using a direct air handler for a data centre?
  • A. Cost of operation as power consumption on these units tend to be higher compared to traditional air conditioning technology.
  • B. The availability of three-phase power due to the high power requirements of these air handler units.
  • C. Space available inside the computer rooms as the air handler space requirement for the inside the Computer room is quite large.
  • D. Temperature, humidity and contamination of the outdoor environment.
Answer: D
Explanation:
Direct air handlers are a type of cooling system that use outdoor air to cool the data centre. They draw in fresh air from outside, filter it, and supply it to the data centre at the desired temperature and humidity level. Direct air handlers can reduce the energy consumption and operating costs of data centres by eliminating the need for mechanical cooling or refrigeration. However, they also have some challenges and limitations that need to be considered. One of the main factors to consider when using direct air handlers for data centres is the temperature, humidity and contamination of the outdoor environment. Depending on the location and climate of the data centre, the outdoor air may not always be suitable for cooling the data centre. For example, if the outdoor air is too hot, too humid, or too polluted, it may not provide enough cooling capacity, or it may damage the IT equipment or cause corrosion. Therefore, direct air handlers need to have sensors and controls to monitor the outdoor air quality and adjust the airflow accordingly. They may also need to have backup cooling systems or supplementary cooling devices, such as evaporative coolers or heat exchangers, to cope with extreme weather conditions or peak loads.

NEW QUESTION # 56
Which Class of Fire involves combustible metals or combustible metal alloys such as magnesium, sodium and potassium?
  • A. Class C
  • B. Class B
  • C. Class A
  • D. Class D
Answer: D
Explanation:
Class D fires involve combustible metals or combustible metal alloys such as magnesium, sodium and potassium. These metals can react violently with water, air, or other chemicals, and require special extinguishing agents1 References: 1: EPI Data Centre Professional (CDCP) Reference Materials, page 16.

NEW QUESTION # 57
is the degree to which a system or component is operational and accessibility when required for use.
  • A. Scalability
  • B. Agility
  • C. Reliability
  • D. Availability
Answer: D
Explanation:
Availability is the degree to which a system, product or component is operational and accessible when required for use. It is one of the attributes of reliability, which is the ability of a system or component to perform its required functions under stated conditions for a specified period of time. Availability can be calculated as the ratio of the expected value of the uptime (the time when the system is functional) to the total time (uptime plus downtime) of a system or component. Availability can also be influenced by factors such as maintainability, fault tolerance, redundancy, diagnostics, and logistics.
References: EPI Data Centre Professional (CDCP®) Preparation Guide, page 8; Availability - Wikipedia; Reliability - ISO 25000.

NEW QUESTION # 58
What should be considered when implementing hot- or cold-aisle containment in an existing computer room?
  • A. It will be more difficult to install power and network cabling in the contained area.
  • B. It creates potential issues with the existing fire suppression system(s).
  • C. Equipment will get too hot at the rear (back) of the rack potentially resulting in more ICT hardware failures.
  • D. The delta-T of the equipment will increase too much causing reliability issues.
Answer: B
Explanation:
Hot- or cold-aisle containment is a strategy to improve the cooling efficiency and reduce the energy consumption of data centers by isolating the hot exhaust air from the cold supply air. However, implementing this strategy in an existing computer room may create potential issues with the existing fire suppression system(s), such as:
*The containment barriers may interfere with the distribution and activation of the fire suppression agents, such as water, gas, or aerosol, and reduce their effectiveness in extinguishing a fire.
*The containment barriers may create pockets of high temperature and pressure that could damage the equipment or the containment structure itself in the event of a fire.
*The containment barriers may obstruct the access and visibility of the fire detection and alarm devices, such as smoke detectors, heat sensors, or manual call points, and delay the response time of the fire suppression system(s).
*The containment barriers may violate the local fire codes and regulations that specify the minimum clearance and ventilation requirements for the data center.
Therefore, when implementing hot- or cold-aisle containment in an existing computer room, it is important to consider the impact on the existing fire suppression system(s) and take appropriate measures to ensure the safety and compliance of the data center, such as:
*Consulting with the fire authorities and the fire suppression system vendor to assess the compatibility and suitability of the containment solution with the existing fire suppression system(s).
*Modifying or upgrading the existing fire suppression system(s) to accommodate the containment solution, such as relocating or adding fire suppression devices, adjusting the discharge rate and pressure, or installing a secondary fire suppression system within the contained area.
*Installing fire-rated containment barriers that can withstand high temperatures and resist the spread of fire and smoke, and that have self-closing or automatic release mechanisms in case of a fire.
*Installing fire detection and alarm devices within the contained area and ensuring their proper integration and communication with the existing fire suppression system(s).
*Conducting regular testing and maintenance of the fire suppression system(s) and the containment solution to ensure their functionality and reliability.

NEW QUESTION # 59
What is the best practice for cutting holes in the raised floor tile?
  • A. Cut the tiles at the corner so the pedestals can be used as a vertical cable manager.
  • B. Anywhere as data centre tiles are designed to allow cut-outs anywhere.
  • C. Draw a line in the middle of the tile and never touch the line when making the cut.
  • D. Draw a cross on the tile and when making a cut-out do not touch a line and avoid the corners.
Answer: D
Explanation:
According to the Raised Floor Installation Manual, the best practice for cutting holes in the raised floor tile is to draw a cross on the tile and when making a cut-out do not touch a line and avoid the corners1. This ensures that the structural integrity and load-bearing capacity of the tile are not compromised. Cutting holes anywhere, touching the line, or cutting the corners can weaken the tile and cause it to crack or collapse1. Additionally, the manual recommends using a drill press or a reciprocating saw with a metal or bi-metal cutting blade, and deburring all sharp edges1.
