1. A data center experiences a utility power failure. The UPS system successfully
carries the critical load, but one generator fails to start. What should operations
personnel do first?
A. Shut down all servers immediately
B. Verify remaining power redundancy and assess runtime capacity
C. Disconnect cooling systems
D. Increase rack density
Answer: B
Rationale: Operators must first confirm available power capacity and redundancy
to maintain continuous operation.
2. What is the primary purpose of a Tier III data center design?
A. Eliminate all maintenance activities
B. Provide concurrently maintainable infrastructure without service interruption
C. Operate without backup power systems
D. Use only a single power path
Answer: B
Rationale: Tier III facilities allow maintenance activities without affecting critical
operations.
3. During a routine inspection, a UPS battery string shows elevated internal
resistance. What is the most appropriate action?
,A. Ignore the condition until failure occurs
B. Investigate battery health and schedule corrective maintenance
C. Increase server loads
D. Disconnect monitoring systems
Answer: B
Rationale: Elevated resistance may indicate battery degradation and reduced
reliability.
4. A hot aisle temperature consistently exceeds design limits while cold aisle
temperatures remain normal. What should be investigated first?
A. Airflow containment effectiveness and return air pathways
B. Building exterior paint color
C. Parking lot lighting
D. Administrative policies
Answer: A
Rationale: Improper airflow management often causes localized overheating.
5. What is the primary objective of environmental monitoring in a data center?
A. Maintain operating conditions within acceptable ranges
B. Increase power consumption
C. Reduce equipment redundancy
D. Eliminate preventive maintenance
Answer: A
Rationale: Environmental monitoring protects equipment reliability and
performance.
6. Which metric is commonly used to evaluate data center energy efficiency?
A. MTBF
B. PUE (Power Usage Effectiveness)
C. RPM
D. RAID
Answer: B
, Rationale: PUE compares total facility energy use to IT equipment energy use.
7. A cooling unit unexpectedly shuts down during peak load conditions. What is
the greatest immediate risk?
A. Rapid temperature increases affecting critical equipment
B. Reduced network latency
C. Improved energy efficiency
D. Increased storage capacity
Answer: A
Rationale: Cooling failures can quickly lead to overheating and equipment
damage.
8. What is the primary purpose of redundancy in critical infrastructure systems?
A. Reduce maintenance requirements
B. Improve fault tolerance and availability
C. Eliminate monitoring needs
D. Reduce power capacity
Answer: B
Rationale: Redundancy minimizes service interruptions during failures.
9. A technician notices uneven power loading between redundant PDUs. What
should be evaluated first?
A. Load balancing and capacity planning
B. Parking availability
C. Exterior security lighting
D. Office occupancy
Answer: A
Rationale: Uneven loading may reduce redundancy effectiveness.
10. Which factor most directly affects server hardware lifespan?
A. Environmental conditions and operating temperatures
B. Wall paint color
