EXIN Certified Data Centre Professional (CDCP) Sample Questions (Q59-Q64):

NEW QUESTION # 59
What is the main risk for a data centre when the water supply fails?

A. Failure to the water supply could result in DX cooling systems to fail.
B. Failure to the water supply could cause issues for the cooling of back-up generators.
C. Failure to the water supply could result in IT failure and/or denial of access to operate.
D. Failure to the water supply could result in sudden changes of the relative humidity in the Computer room.

Answer: B

Explanation:
Back-up generators are essential for providing power to the data centre in case of a utility outage. However, back-up generators also generate a lot of heat, which needs to be dissipated by a cooling system. The cooling system may rely on water supply, either from the municipal network or from a dedicated tank. If the water supply fails, the cooling system may not function properly, leading to overheating and potential damage to the generators. This could compromise the reliability and availability of the data centre power supply and cause downtime or data loss.

NEW QUESTION # 60
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 exhaust (outlet) of the air conditioner.
C. It is the value measured at the front of the rack of the aisle the air conditioner is situated.
D. It is the average value between the intake and 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.

NEW QUESTION # 61
When having two non-synchronized power sources, the ATS / STS need to be of the type:

A. Both make before break or break before make can be used.
B. Both an ATS and STS can never handle two non-synchronized sources.
C. Make before break.
D. Break before make.

Answer: D

Explanation:
When having two non-synchronized power sources, the ATS / STS need to be of the type break before make, which means that the switch disconnects from one source before connecting to the other source. This prevents any short circuit, back feed, or phase mismatch that could occur if the two sources were connected simultaneously. Break before make switches are also known as open transition switches, because they create a brief interruption in the power supply during the switching process. This interruption is usually acceptable for most ICT equipment, as they have internal power supplies or batteries that can handle the transient. However, if the interruption is not acceptable, then the two power sources need to be synchronized before switching, which requires a make before break switch, also known as a closed transition switch. Make before break switches connect to the second source before disconnecting from the first source, which ensures a seamless transfer of power without any interruption. However, make before break switches require that the two sources have the same voltage, frequency, and phase, which can be achieved by using a synchronization module or a phase-locked loop.

NEW QUESTION # 62
systems are designed specifically to protect the structure of a building.

A. Inergen
B. Water sprinkler
C. Total Flooding
D. Pro-inert

Answer: B

Explanation:
Water sprinkler systems are designed to protect the structure of a building from fire by suppressing or extinguishing the flames with water. Water sprinkler systems are typically installed in the ceiling or walls of a building and are activated by heat or smoke detectors. Water sprinkler systems can reduce the risk of fire spreading and causing structural damage to the building.

NEW QUESTION # 63
Which one of the following is a Natural Disaster?

A. Blackouts
B. Grid Failure
C. Human Error
D. Hurricanes

Answer: D

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.
