Sample questions and explanations
Question 1 · Module 1: The Mission Critical Site
What best describes a mission critical site?
- A.A facility whose failure would seriously disrupt business operations
- B.A facility that is larger than all other company buildings
- C.A facility that operates only during normal office hours
- D.A facility that houses only office PCs and printers
Correct answer: A — A facility whose failure would seriously disrupt business operations
Explanation: A site is mission critical because of the impact of losing it, not its size. If its services stop, core business processes stop or are seriously harmed.
Question 2 · Module 1: The Mission Critical Site
Why has business dependence on the data centre grown over time?
- A.Fewer customers now use online services than before
- B.More core business processes now run as digital services
- C.Paper records have replaced most electronic systems
- D.Companies now store less data than they used to
Correct answer: B — More core business processes now run as digital services
Explanation: Ordering, payments, communication and records are now largely digital. When those systems depend on the data centre, the business depends on it too.
Question 3 · Module 2: Data Centre Standards
What is the key difference between a standard and a guideline?
- A.A guideline is always legally binding, while a standard is not
- B.A standard is written only for one company, a guideline for countries
- C.A standard sets requirements to follow, while a guideline gives recommendations
- D.There is no practical difference between the two documents
Correct answer: C — A standard sets requirements to follow, while a guideline gives recommendations
Explanation: Standards contain requirements that designs or products are expected to meet. Guidelines advise on good practice but allow more discretion in how they are applied.
Question 4 · Module 2: Data Centre Standards
Which description best fits a regulation?
- A.A voluntary recommendation published by a trade association
- B.A suggestion made by a single equipment manufacturer
- C.An internal preference with no external enforcement
- D.A mandatory rule issued by an authority that must be complied with
Correct answer: D — A mandatory rule issued by an authority that must be complied with
Explanation: Regulations have legal force behind them, so compliance is not optional. Standards and guidelines may become mandatory if a regulation or contract references them.
Question 5 · Module 3: Data Centre Location, Building and Construction
When selecting a data centre site, why is flood history one of the first things to check?
- A.Flood water improves cooling efficiency for the site
- B.A flooded site is cheaper to insure than a dry site
- C.Flooding can disable the whole facility and damage equipment beyond repair
- D.Flood risk only matters for buildings with basements
Correct answer: C — Flooding can disable the whole facility and damage equipment beyond repair
Explanation: Water entering electrical rooms, generators or the computer room can shut the site down and destroy equipment. A site with a known flood risk should normally be avoided or heavily mitigated.
Question 6 · Module 3: Data Centre Location, Building and Construction
Which combination of natural risks should a site selection study assess for a proposed location?
- A.Only the average temperature on the hottest day
- B.Only risks that have occurred in the last month
- C.No natural risks if the building is newly built
- D.Seismic activity, storms and other local natural hazards
Correct answer: D — Seismic activity, storms and other local natural hazards
Explanation: Earthquakes, high winds, storms and similar hazards can damage the building or cut off its utilities. The study should review the hazards that realistically apply to that location.
Question 7 · Module 4: Raised Access Flooring and Suspended Ceiling
What is the primary purpose of a raised access floor in a data centre?
- A.To increase the structural strength of the building slab so heavier racks can be installed
- B.To provide thermal insulation between the data hall and the floor below it
- C.To create a flexible plenum space below the floor for air distribution, cabling and services that can be accessed by lifting panels
- D.To permanently hide all services so they never need to be accessed again
Correct answer: C — To create a flexible plenum space below the floor for air distribution, cabling and services that can be accessed by lifting panels
Explanation: A raised floor creates a usable void underneath. Services in that void can be changed or added by lifting panels, and the same void often distributes cold air.
Question 8 · Module 4: Raised Access Flooring and Suspended Ceiling
How does a stringer-based raised floor system differ from other systems?
- A.Pedestals are glued directly to the panels so the floor acts as one solid sheet
- B.Panels are bolted only at their corners with no support along their edges
- C.Panels rest directly on the slab with no pedestals at regular intervals
- D.Pedestals are connected to each other by horizontal stringers that support the edges of the floor panels
Correct answer: D — Pedestals are connected to each other by horizontal stringers that support the edges of the floor panels
Explanation: In a stringer system the pedestals are linked by stringers. Those stringers add lateral stability and support the panel edges.
Question 9 · Module 5: Light
What does the unit lux measure?
- A.Illuminance, meaning the amount of light falling on a surface per unit area
- B.The total light output emitted by a lamp in all directions
- C.The electrical power consumed by a lighting circuit in one hour
- D.The brightness of a light source as seen looking directly at it
Correct answer: A — Illuminance, meaning the amount of light falling on a surface per unit area
Explanation: Lux measures illuminance on a surface, in lumens per square metre. It tells you how much light actually lands where work is done.
Question 10 · Module 5: Light
What does the unit lumen measure?
- A.The amount of light falling on one square foot of surface
- B.The total amount of visible light emitted by a source
- C.The amount of light falling on one square metre of surface
- D.The ratio between daylight and artificial light in a room
Correct answer: B — The total amount of visible light emitted by a source
Explanation: A lumen measures luminous flux, the total light a source produces. Lux and foot-candles then describe how that light is spread over a surface.
