NEW QUESTION # 37
Do I need to check the local standards if I already comply to international standards?
- A. You need to check the local standards to ensure compliance to these standards.
- B. Compliance to only international standards is good enough as most local standards are derived from international standards.
- C. Local standards do not to be checked as some countries have too many local standards, which will slow down the data centre construction.
- D. Data centres only need to comply to international standards since they are connected to a worldwide international network infrastructure.
Answer: A
Explanation:
Data centre design and infrastructure standards can vary from country to country, depending on the local regulations, codes, and practices. Therefore, it is important to check the local standards before designing, building, or operating a data centre in a specific location. Compliance to only international standards may not be sufficient or adequate to meet the local requirements, which could result in legal, financial, or operational risks. For example, some countries may have stricter fire safety, environmental, or energy efficiency standards than the international ones. Some countries may also have different electrical standards, such as voltage, frequency, or plug types. By checking the local standards, you can ensure that your data centre is compliant, safe, and efficient in the local context.

NEW QUESTION # 38
From the list below, which sensor detects smoke the fastest?
- A. lonization detector
- B. Photoelectric detector
- C. VESDA/HSSD
- D. Sprinkler bulbs
Answer: C
Explanation:
VESDA (Very Early Smoke Detection Apparatus) or HSSD (High Sensitivity Smoke Detection) systems are the fastest smoke sensors among the options listed. These systems use a network of pipes to draw air samples from the protected area and analyze them using a laser-based detection chamber. VESDA/HSSD systems can detect smoke at very low concentrations, typically in the range of 0.005 to 20 percent obscuration per meter.
This means they can provide early warning of a fire before it becomes visible or spreads. VESDA/HSSD systems are ideal for data centers and other critical facilities that require high levels of fire protection and minimal downtime.

NEW QUESTION # 39
What type of heal does ICT equipment generate?
- A. Latent heal
- B. Radiant heat
- C. Sensible heaT
- D. Both latent and sensible heat
Answer: C
Explanation:
According to the Certified Data Centre Professional (CDCP) reference materials, ICT (Information and Communication Technology) equipment such as servers, switches, and storage devices generate sensible heat.
Sensible heat is the heat energy that causes a change in temperature of the air but does not contribute to humidity or moisture content. This is in contrast to latent heat, which involves a change in moisture (humidity) in the air, such as from evaporation or condensation.
ICT equipment does not introduce moisture into the environment; it only raises the temperature of the surrounding air, making it sensible heat. Proper data center cooling focuses on removing this sensible heat load to maintain optimal equipment operating conditions. Latent heat loads, such as those from people or water leaks, are typically not generated by ICT equipment and are managed differently in facility design.
Radiant heat is a minor consideration and typically refers to heat transferred by electromagnetic waves (e.g., from sunlight or hot surfaces), not the primary mode of heat transfer from ICT equipment, which is primarily through convection (airflow) and is measured as sensible heat.

NEW QUESTION # 40
Which one of the following is a Natural Disaster?
- A. Human Error
- B. Hurricanes
- C. Grid Failure
- D. Blackouts
Answer: B
Explanation:
According to the CDCP Preparation Guide, a natural disaster is a catastrophic event that is caused by natural forces and has a significant impact on human lives, property, and environment. Hurricanes are examples of natural disasters, as they are powerful storms that form over warm ocean waters and produce strong winds, heavy rain, storm surges, and flooding. Grid failure, blackouts, and human error are not natural disasters, but rather man-made or technological disasters that result from failures or errors in human systems or activities.

NEW QUESTION # 42
When dealing with glass door racks, cool air is injected into the rack from:
- A. The top of the rack through the fans and vents mounted inside the rack.
- B. The rear door in a downflow direction.
- C. The front door in a downflow direction.
- D. The bottom of the rack.
Answer: B
Explanation:
Glass door racks are a type of rack that have solid glass front doors and rear door heat exchangers (RDHx).
RDHx are devices that use facility coolant to absorb heat from the exhaust air of the IT equipment and return cool air to the room. RDHx can be either passive or active, depending on the fan configuration. In general, IT hardware within the rack is air-cooled and the door heat exchanger uses facility coolant to absorb heat from exhaust air to return air to the facility at or near inlet air temperature to the rack. This rear door heat exchanger can either be a passive or active solution. When dealing with glass door racks, cool air is injected into the rack from the rear door in a downflow direction. This means that the cool air flows from the top to the bottom of the rack, following the natural convection of the hot air rising. This way, the cool air can reach all the IT equipment in the rack and prevent hot spots or overheating.

- A. Draw a line in the middle of the tile and never touch the line when making the cut.
- B. Cut the tiles at the corner so the pedestals can be used as a vertical cable manager.
- C. Anywhere as data centre tiles are designed to allow cut-outs anywhere.
- 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.

NEW QUESTION # 49
Sprinkler heads used in computer rooms activate at what temperature?
- A. 57 °C (135 °F)
- B. Only on direct contact with a flame
- C. 70 C (158 °F)
- D. 27 °C (81 °F)
Answer: A
Explanation:
Sprinkler heads used in computer rooms activate at 57 °C (135 °F), which is the standard temperature rating for ordinary sprinklers. This is the temperature at which the heat-sensitive element of the sprinkler head, such as a glass bulb or a fusible link, breaks or melts, allowing water to flow from the sprinkler. Sprinkler heads are designed to activate only when exposed to a fire, not to ambient temperature fluctuations. Therefore, sprinkler heads should be installed at a sufficient distance from the heat sources, such as servers, racks, or ducts, to avoid accidental activation. Sprinkler heads should also be selected and installed in accordance with the relevant standards and codes, such as NFPA 13 and NFPA 75.

What do the numbers represent?
- A. The first number represents the required distance to single-phase power cabling; the second number represents the required distance to three-phase cabling.
- B. The first number represents the diameter of the core; the second number represents the diameter of the cladding in microns.
- C. The first number represents the diameter of the core; the second number represents the actual diameter cable including the buffer and jacket.
- D. The first number represents the distance for a 10 Gb/s connection; the second number represents the distance for a 1 Gb/s connection.
Answer: B
Explanation:
Optical fiber cables are composed of a core, a cladding, and a coating. The core is the central part of the fiber that carries the light signal. The cladding is the layer surrounding the core that reflects the light back into the core and prevents signal loss. The coating is the protective layer that covers the cladding and provides mechanical strength and environmental protection. The specifications of an optical fiber cable indicate the dimensions of the core and the cladding in microns (#m), which are one millionth of a meter. For example, a
50/125 #m cable has a core diameter of 50 #m and a cladding diameter of 125 #m. The coating diameter is usually 250 #m, but it is not part of the specifications.

NEW QUESTION # 52
Which is the most damaging type of floor load?
- A. Rolling Load (RL)
- B. Concentrated Load / Point Load (CP/ PL)
- C. All loads are equally damaging to raised floor tiles
- D. Uniformly Distributed Load (UDL)
Answer: A
Explanation:
The most damaging type of floor load for raised floor tiles in a data centre is the rolling load (RL), according to the CDCP Preparation Guide1 and various web sources234. A rolling load is the load that is applied by a moving object, such as a pallet jack, a forklift, or a rack on wheels. A rolling load can cause more stress and fatigue on the raised floor tiles than a static load, such as a concentrated load (CP) or a uniformly distributed load (UDL), because it creates dynamic forces and impacts that can crack, dent, or deform the tiles. Moreover, a rolling load can also damage the pedestals and stringers that support the tiles, and cause the tiles to become loose or misaligned. Therefore, when designing and installing a raised floor system, it is important to consider the maximum rolling load that the tiles can withstand, and to use appropriate materials and methods to enhance the strength and durability of the tiles. For example, some possible solutions include using steel or concrete-filled tiles, reinforcing the edges and corners of the tiles, and using locking or gravity-held systems to secure the tiles.

NEW QUESTION # 54
What are the four main components of a refrigeration circuit?
- A. Thermostat, monitoring interface, indoor unit, outdoor unit
- B. Condenser, expansion valve, buffer tank, de-icing unit
- C. Evaporation, membrane filter, monitor sensor, pressure valve
- D. Evaporator, compressor, condenser, expansion valve
Answer: D
Explanation:
The four main components of a refrigeration circuit are the evaporator, the compressor, the condenser, and the expansion valve, according to the CDCP Preparation Guide1 and various web sources234. A refrigeration circuit is a system that transfers heat from a low-temperature region to a high-temperature region, using a working fluid called refrigerant. The refrigeration circuit operates in a closed loop, where the refrigerant changes its state from liquid to vapor and back to liquid, while absorbing and releasing heat. The four main components of the refrigeration circuit perform the following functions:
*The evaporator is a heat exchanger that absorbs heat from the low-temperature region, such as the data centre room, and transfers it to the refrigerant. The refrigerant enters the evaporator as a low-pressure, low-temperature liquid, and leaves the evaporator as a low-pressure, low-temperature vapor.
*The compressor is a mechanical device that increases the pressure and temperature of the refrigerant vapor.
The refrigerant enters the compressor as a low-pressure, low-temperature vapor, and leaves the compressor as a high-pressure, high-temperature vapor.
*The condenser is another heat exchanger that releases heat from the refrigerant to the high-temperature region, such as the outside air or water. The refrigerant enters the condenser as a high-pressure, high-temperature vapor, and leaves the condenser as a high-pressure, low-temperature liquid.
*The expansion valve is a device that reduces the pressure and temperature of the refrigerant liquid. The refrigerant enters the expansion valve as a high-pressure, low-temperature liquid, and leaves the expansion valve as a low-pressure, low-temperature liquid. The expansion valve also controls the flow of the refrigerant into the evaporator, depending on the cooling load.

NEW QUESTION # 56
What is the main difference between an Environmental Monitoring System (EMS) and a Building Management System (BMS)?
- A. An EMS provides local alarms. A BMS provides both local and remote alarms.
- B. A BMS is only able to monitor dry contacts (on/off). An EMS can also monitor analog values.
- C. An EMS monitors only. A BMS monitors and controls.
- D. A BMS only operates as a stand-alone system. An EMS can be configured as a redundant system.
Answer: C
Explanation:
The main difference between an Environmental Monitoring System (EMS) and a Building Management System (BMS) is that an EMS monitors only, while a BMS monitors and controls. An EMS is a system that collects and records data from various sensors and devices that measure environmental parameters, such as temperature, humidity, air quality, power, and water. An EMS provides alerts and reports based on the data, but it does not control or adjust the environmental conditions. A BMS is a system that integrates and manages various building systems, such as HVAC, lighting, security, fire, and access. A BMS not only monitors the data from these systems, but also controls and optimizes them to achieve the desired performance and efficiency. A BMS can also communicate with an EMS to receive data and provide feedback.

NEW QUESTION # 57
Which one of the following is a device that uses circulating chilled water to remove heat?
- A. Computer Room Air System Unit (CRAS)
- B. Computer Room Air Handling Unit (CRAH)
- C. Computer Room Air Suspension Unit (CRAS)
- D. Computer Room Air Suppression Unit (CRAS)
Answer: B
Explanation:
A computer room air handling unit (CRAH) is a device that uses circulating chilled water to remove heat from the data center environment. A CRAH consists of a fan, a coil, and a filter. The fan draws the warm air from the data center and passes it through the coil, where the heat is transferred to the chilled water. The chilled water is supplied by a chiller or a cooling tower, and the cooled air is returned to the data center. A CRAH is different from a computer room air conditioning unit (CRAC), which uses a refrigerant instead of chilled water to cool the air.
