CDCP Data Center Infrastructure Management 2 — Questions and Answers
Question 1: Which DCIM capability allows administrators to model planned equipment changes before physically implementing them?
- Capacity forecasting
- What-if analysis (Correct answer)
- Asset discovery
- SNMP polling
Correct answer: What-if analysis
What-if analysis lets administrators simulate moves, adds, and changes virtually to assess impact before touching live infrastructure.
Question 2: In DCIM, a 'stranded capacity' report identifies which condition?
- Servers consuming more power than provisioned
- Available power or cooling that cannot be used due to mismatches (Correct answer)
- UPS batteries that have exceeded their service life
- Racks with insufficient cable management
Correct answer: Available power or cooling that cannot be used due to mismatches
Stranded capacity refers to resources (power, cooling, space) that are technically available but inaccessible because of mismatches between power, cooling, or space constraints.
Question 3: What is the primary function of a Building Management System (BMS) integration within DCIM?
- Automating server OS patching
- Aggregating facility-level sensor data into a unified dashboard (Correct answer)
- Managing Active Directory user accounts
- Controlling network switch configurations
Correct answer: Aggregating facility-level sensor data into a unified dashboard
BMS integration feeds facility-level data (HVAC, lighting, generators) into DCIM for holistic monitoring and management.
Question 4: Which metric does DCIM use to measure the ratio of IT equipment energy to total facility energy?
- DCIE (Data Center Infrastructure Efficiency) (Correct answer)
- WUE (Water Usage Effectiveness)
- ERE (Energy Reuse Effectiveness)
- CUE (Carbon Usage Effectiveness)
Correct answer: DCIE (Data Center Infrastructure Efficiency)
DCIE is the inverse of PUE, expressed as a percentage, representing IT load divided by total facility power.
Question 5: A DCIM system triggers an alert when a rack's power draw exceeds its breaker capacity. What type of monitoring is this?
- Predictive monitoring
- Threshold-based alerting (Correct answer)
- Baseline deviation detection
- Anomaly correlation
Correct answer: Threshold-based alerting
Threshold-based alerting fires notifications when a measured value crosses a pre-configured limit, such as exceeding breaker capacity.
Question 6: Which data source is most critical for accurate DCIM floor-plan visualization?
- Network topology diagrams
- As-built drawings with precise rack coordinates (Correct answer)
- Server BIOS configuration files
- Cloud provider billing reports
Correct answer: As-built drawings with precise rack coordinates
As-built drawings with accurate rack positions and room dimensions form the foundation of correct DCIM spatial models.
Question 7: In DCIM change management workflow, what is the purpose of a 'work order'?
- Recording historical energy consumption
- Authorizing and documenting a specific infrastructure change task (Correct answer)
- Scheduling automated firmware updates
- Generating capacity planning reports
Correct answer: Authorizing and documenting a specific infrastructure change task
A work order formally authorizes a specific task, tracks its status, and creates an audit trail for infrastructure changes.
