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

16. Frage
Which of statements below is true?

A. Single-mode cabling can use both LED and laser as a light source.
B. Multi-mode cabling is more expensive than single-mode cabling.
C. Single-mode cabling is more expensive than multi-mode cabling.
D. Multi-mode cabling can cross longer distances.

Antwort: C

Begründung:
Single-mode cabling and multi-mode cabling are two types of fiber optic cables that differ in their core diameter, wavelength, light source, bandwidth, distance, and cost. Single-mode cabling has a smaller core diameter and uses a laser as a light source, which enables it to transmit data over longer distances and higher bandwidths. However, single-mode cabling is also more expensive than multi-mode cabling, because it requires more precise alignmentand splicing, and more costly light sources and connectors. Multi-mode cabling has a larger core diameter and uses LEDs or VCSELs as a light source, which makes it cheaper and easier to install and maintain. However, multi-mode cabling also has a shorter distance and lower bandwidth than single-mode cabling, because it suffers from more modal dispersion and attenuation.

17. Frage
is the degree to which a system or component is operational and accessibility when required for use.

A. Scalability
B. Availability
C. Agility
D. Reliability

Antwort: B

Begründung:
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.

18. Frage
Which one of the following is a device that uses circulating chilled water to remove heat?

A. Computer Room Air Handling Unit (CRAH)
B. Computer Room Air System Unit (CRAS)
C. Computer Room Air Suppression Unit (CRAS)
D. Computer Room Air Suspension Unit (CRAS)

Antwort: A

Begründung:
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.

19. Frage
Do I need to check the local standards if I already comply to international standards?

A. Data centres only need to comply to international standards since they are connected to a worldwide international network infrastructure.
B. You need to check the local standards to ensure compliance to these standards.
C. Compliance to only international standards is good enough as most local standards are derived from international standards.
D. Local standards do not to be checked as some countries have too many local standards, which will slow down the data centre construction.

Antwort: B

Begründung:
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.

20. Frage
Which one of the following is an Audible Signaling and Notification Device?

A. Alarms
B. Clocks
C. Sirens
D. Strobes

Antwort: C

Begründung:
According to the CDCP® Preparation Guide, an audible signaling and notification device is a device that produces a sound to alert or notify the occupants of a data center of an event or condition. Sirens are examples of such devices, as they can emit loud and distinctive tones to warn of fire, emergency, or security incidents.
Strobes, on the other hand, are visual signaling and notification devices that produce flashes of light to attract attention or convey information. Alarms and clocks are not specific types of devices, but rather general terms that can refer to various audible or visual devices.
