CDCP Data Center Infrastructure Management 3 — Questions and Answers
Question 1: Which DCIM data collection method requires installing software agents on managed servers?
- SNMP polling
- IPMI out-of-band monitoring
- Agent-based monitoring (Correct answer)
- Modbus TCP integration
Correct answer: Agent-based monitoring
Agent-based monitoring installs software on each server to collect detailed in-band metrics unavailable via SNMP or IPMI.
Question 2: What does a DCIM 'dependency map' primarily illustrate?
- The electrical one-line diagram of the UPS chain
- Relationships between IT assets, power paths, and cooling zones (Correct answer)
- IP address allocation across VLANs
- Software licensing dependencies between applications
Correct answer: Relationships between IT assets, power paths, and cooling zones
A dependency map shows how IT equipment relates to its power sources, cooling infrastructure, and network connectivity for impact analysis.
Question 3: A data center manager wants to identify which racks will exceed 80% power capacity within 90 days. Which DCIM feature addresses this?
- Real-time power monitoring
- Capacity planning with trend forecasting (Correct answer)
- Environmental alarm management
- Asset lifecycle tracking
Correct answer: Capacity planning with trend forecasting
Capacity planning with trend forecasting projects future utilization based on historical growth rates to anticipate constraint points.
Question 4: Which protocol is commonly used by DCIM systems to communicate with intelligent PDUs for real-time outlet-level power data?
- FTP
- SNMP (Correct answer)
- SMTP
- NFS
Correct answer: SNMP
SNMP (Simple Network Management Protocol) is the standard protocol for querying intelligent PDUs for power consumption data.
Question 5: In DCIM asset management, what distinguishes a 'logical asset' from a 'physical asset'?
- Logical assets have a barcode; physical assets do not
- Logical assets represent software or virtual entities; physical assets are tangible hardware (Correct answer)
- Logical assets are tracked by weight; physical assets by IP address
- Logical assets require cooling; physical assets do not
Correct answer: Logical assets represent software or virtual entities; physical assets are tangible hardware
Physical assets are tangible hardware items, while logical assets represent virtual machines, software instances, or abstract entities mapped to physical hardware.
Question 6: Which practice ensures DCIM data remains accurate after a large-scale hardware refresh?
- Running a passive network scan weekly
- Performing a physical audit and reconciling against DCIM records (Correct answer)
- Increasing SNMP polling frequency
- Archiving old asset records without deletion
Correct answer: Performing a physical audit and reconciling against DCIM records
A physical walkthrough audit with reconciliation against the DCIM database corrects discrepancies introduced during hardware changes.
Question 7: What is 'hot aisle containment' monitoring in DCIM primarily designed to measure?
- Network latency in the top-of-rack switch
- Return air temperature to CRAC/CRAH units from server exhausts (Correct answer)
- UPS battery cell voltage levels
- Generator fuel consumption rate
Correct answer: Return air temperature to CRAC/CRAH units from server exhausts
Hot aisle containment monitoring measures the temperature of hot exhaust air returning to cooling units, ensuring proper thermal management.
