EXIN Certified Data Centre Professional (CDCP) Sample Questions (Q66-Q71):

NEW QUESTION # 66
Which type of Fire Detection Device is recommended for protecting a Data Center?

A. Smoke detector
B. Flame detector
C. Heat detector
D. None of the above

Answer: A

Explanation:
According to the CDCP Preparation Guide, smoke detectors are the most common type of fire detection devices used in data centers, as they can detect a fire in its early stages and provide early warning to the occupants and authorities. Smoke detectors can be either spot-type or air-aspirating, depending on the design and goals of the data center. Spot-type detectors are inexpensive and simple, but may cause activation delay and false alarms. Air-aspirating detectors are more sensitive and reliable, but may require more maintenance and installation costs. Both types of detectors should be installed in accordance with the relevant standards and codes, such as NFPA 72 and EN 54.

NEW QUESTION # 67
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 Suppression Unit (CRAS)
C. Computer Room Air Suspension Unit (CRAS)
D. Computer Room Air Handling Unit (CRAH)

Answer: D

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.

NEW QUESTION # 68
Which one of the following is a factor that can affect Availability and Reliability?

A. Inadequate Cooling
B. Employee Salaries
C. Attenuation
D. Radio Active Waves

Answer: A

Explanation:
Availability and reliability are two important aspects of data centre performance that measure how often the system is operational and how dependable it is. According to the EPI Data Centre Framework, availability is the percentage of time that a system or component is in an operable state, while reliability is the probability that a system or component will perform its required function under given conditions for a specified period of time. Both availability and reliability can be affected by various factors, such as design, maintenance, human error, power supply, security, etc. One of the factors that can have a significant impact on both availability and reliability is cooling. Cooling is essential for maintaining the optimal temperature and humidity levels for the IT equipment and preventing overheating, which can cause failures, downtime, and reduced lifespan.
Inadequate cooling can result from insufficient capacity, poor airflow management, faulty components, or environmental conditions. Inadequate cooling can reduce the availability and reliability of the data centre by increasing the risk of thermal stress, hot spots, performance degradation, and equipment damage. Therefore, cooling is a critical factor that can affect availability and reliability in a data centre.

NEW QUESTION # 69
What is the primary reason to install a monitoring system in the data centre?

A. To notice abnormalities early so that actions can be taken to avoid disasters
B. To be able to collect data for capacity planning
C. To create a proper asset database
D. To implement automated change management

Answer: A

Explanation:
The primary reason to install a monitoring system in the data centre is to notice abnormalities early so that actions can be taken to avoid disasters, according to the CDCP Preparation Guide1 and various web sources234. A monitoring system is a system that collects and analyzes data about the power, cooling, environmental, and security conditions in the data centre, and alerts the operators or managers about any issues or threats that may affect the performance, availability, or reliability of the data centre. A monitoring system can help to prevent or minimize the impact of disasters, such as power outages, fire, water damage, overheating, equipment failure, or cyberattacks, by providing timely and accurate information that enables fast and corrective action. A monitoring system can also help to improve the energy efficiency, capacity planning, and asset management of the data centre, by providing useful insights and trends that support informed decision making.

C. The patch cable should always be the same or a higher class the structured cable.
D. Patch cables can only be used in combination with flat patch panels.
