CDCP - Certified Data Centre Professional Data Center Design Principles Questions and Answers

Question 1

A data center cooling system is designed to operate at full capacity using two identical chiller units.
To improve reliability, the facility has installed a total of three identical units.
What is the redundancy level of this cooling system?

Accepted Answer

N+1

Answer

N

Answer

2N

Answer

N+2

Question 2

Which fire suppression system is specifically designed to minimize the risk of accidental water damage in a data center by requiring two independent events to occur—such as a smoke detector alarm and the separate thermal activation of a sprinkler head—before releasing water?

Accepted Answer

Pre-Action Sprinkler System

Answer

Wet Pipe Sprinkler System

Answer

Gaseous Clean Agent System

Answer

Dry Pipe Sprinkler System

Question 3

During the site selection process for a new, mission-critical data center, which of the following is considered a primary geographic risk that should be avoided?

Accepted Answer

Location within a designated 100-year floodplain

Answer

Proximity to a major highway interchange

Answer

Availability of only two diverse fiber optic providers

Answer

Location more than 30 miles from a major city

Question 4

What is the primary purpose of specifying both a Uniformly Distributed Load (UDL) and a Concentrated Load rating for a data center's raised floor system?

Accepted Answer

To account for the floor's overall weight capacity versus its ability to support a heavy point load, like a rack caster.

Answer

To differentiate between the load-bearing capacity of access panels versus the support pedestals.

Answer

To comply with separate fire safety and seismic bracing regulations.

Answer

To measure the floor's resistance to rolling loads during equipment moves versus its static load capacity.

Question 5

In a layered physical security model for a data center, which of the following controls is most characteristic of the 'Room Layer' that protects the data hall (white space) itself?

Accepted Answer

A mantrap entrance with biometric authentication.

Answer

A perimeter fence with vehicle crash bollards.

Answer

Security guards stationed in the main building lobby.

Answer

Individually keyed locks on each server rack.

Question 6

According to the Uptime Institute's Tier Standard, which key capability distinguishes a Tier IV data center from a Tier III data center?

Accepted Answer

The automatic ability to withstand any single unplanned component or path failure without impacting the IT load.

Answer

The ability to perform planned maintenance without disrupting IT operations.

Answer

The presence of a backup generator for utility power failures.

Answer

The use of N+1 redundancy in its primary cooling systems.
