EXIN Certified Data Centre Professional (CDCP) CDCP Prüfungsfragen mit Lösungen (Q16-Q21):

16. Frage
What is the best practice for cutting holes in the raised floor tile?

A. Draw a cross on the tile and when making a cut-out do not touch a line and avoid the corners.
B. Anywhere as data centre tiles are designed to allow cut-outs anywhere.
C. Cut the tiles at the corner so the pedestals can be used as a vertical cable manager.
D. Draw a line in the middle of the tile and never touch the line when making the cut.

Antwort: A

Begründung:
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.

17. Frage
Which formula is correct?

A. Watt = VoIt-Ampere / Power Factor
B. Watt = Volt-Ampere * Power Factor
C. Power Factor = Volt Ampere ' Watt
D. Volt-Ampere = Watt * Power Factor

Antwort: B

18. Frage
What is a requirement for both CCTV cameras and recording equipment?

A. They must be of the same brand.
B. Both must be placed inside the Computer room.
C. Both must be connected to a UPS.
D. CCTV cameras can only be used to cover the outside of the building, where as the recording equipment needs to be located in a secure area.

Antwort: C

Begründung:
A UPS (Uninterruptible Power Supply) is a device that provides backup power to electrical equipment in case of a power outage or fluctuation. A UPS is essential for both CCTV cameras and recording equipment, as it ensures that the surveillance system can continue to operate and record without interruption or data loss. A UPS can also protect the CCTV cameras and recording equipment from damage caused by power surges or spikes. Connecting both CCTV cameras and recording equipment to a UPS is a requirement for data centres, as it enhances the security and reliability of the surveillance system.

19. Frage
Looking from within the Computer room, what should the door-swing (opening) direction be?

A. Depends on the type of Computer room
B. Instead of swinging doors, sliding doors are preferred
C. Inwards, code permitted
D. Outwards, code permitted

Antwort: D

Begründung:
For safety and emergency egress, doors should swing outwards (towards the exit). This is a common building code and best practice in data centers.

20. Frage
What are the four main components of a refrigeration circuit?

A. Evaporator, compressor, condenser, expansion valve
B. Condenser, expansion valve, buffer tank, de-icing unit
C. Evaporation, membrane filter, monitor sensor, pressure valve
D. Thermostat, monitoring interface, indoor unit, outdoor unit

Antwort: A

Begründung:
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.
