✍️ Sample CDCP Questions & Answers
1. The following inlet temperature range is advised by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE):
The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) provides industry standards for data center environments. Their recommended inlet temperature range for IT equipment is 68° to 77°F (20° to 25°C). This range ensures optimal equipment performance and reliability while allowing for energy efficiency in cooling.
2. What is the primary function of a DCIM (Data Centre Infrastructure Management) system?
DCIM tools provide real-time visibility and management of physical infrastructure including power, cooling, space, and assets.
3. What is the primary purpose of an out-of-band (OOB) management network in a data center?
An OOB management network is physically separate from production traffic paths, allowing administrators to access, configure, or recover devices even when the in-band network is down.
4. What is 'N+1 redundancy' in the context of data center cooling systems?
N+1 redundancy means one additional cooling unit beyond the number needed (N) to handle full load, so if any single unit fails, the remaining units can still support the entire load.
5. Which renewable energy procurement model allows a data centre operator to claim renewable energy credits without physically receiving green electricity at the facility?
RECs (Renewable Energy Certificates) represent the environmental attributes of one MWh of renewable generation and can be purchased separately from the physical electricity supply.
6. Which power topology provides the best isolation of IT equipment from utility power anomalies?
Online double-conversion (VFI - Voltage and Frequency Independent) UPS continuously converts AC to DC and back to AC, completely isolating IT loads from all utility disturbances.
