# Data Center Operations & Monitoring Quiz Quiz · Operations & Monitoring Ten questions on how critical facilities run day to day: procedures, change control, maintenance strategy, monitoring, and incident response. Each answer comes with a short explanation. 10 questions About 5 minutes Intermediate ## Quiz questions 1. Question 1 Which document is a step-by-step plan for a specific, planned change to live critical infrastructure, such as putting a UPS on maintenance bypass? - SOP (standard operating procedure) - MOP (method of procedure) - EOP (emergency operating procedure) - SLA (service level agreement) **Show answer** **Answer: a MOP.** SOPs cover routine, repeatable tasks like equipment rounds, while MOPs cover planned work on critical systems with exact steps, hold points, approvals, and a back-out plan. EOPs tell responders what to do when something fails. [Read the operations guide](https://datacentertraining.us/learn/data-center-operations.html). 2. Question 2 Which statement about change management in a critical facility is correct? - Emergency changes skip review and documentation entirely - It applies only to IT software, not to power and cooling systems - Approval is needed only when a change is expected to cause an outage - Changes to critical infrastructure are risk-assessed, approved, scheduled, and documented, with a back-out plan, before work starts **Show answer** **Answer: every change is assessed, approved, and documented first.** Many outages start with a change or maintenance task, so change review is where risk gets caught. Emergency changes still follow an expedited path and are documented afterward. [Data Center Operations Management](https://datacentertraining.us/courses/data-center-operations-management.html) covers change control. 3. Question 3 What is the difference between preventive and predictive maintenance? - Preventive is done on a fixed schedule or run hours; predictive uses condition data, such as vibration or infrared scans, to act when indicators show it is needed - Preventive is done after a failure; predictive is done before one - They are two names for the same calendar-based practice - Predictive maintenance applies only to IT equipment, not facility systems **Show answer** **Answer: schedule-based versus condition-based.** Preventive work follows the calendar or run hours, like quarterly filter changes. Predictive work watches condition, like rising bearing vibration or a hot lug on an infrared scan, and fixes it before it fails; repairing after failure is reactive maintenance. [Preventive Maintenance Planning](https://datacentertraining.us/courses/preventive-maintenance-planning.html) covers both strategies. 4. Question 4 What does a CMMS do for a facilities team? - Controls chiller staging in real time - Tracks rack power, space, and network ports for capacity planning - Schedules and tracks work orders, preventive maintenance tasks, asset history, and spare parts - Monitors network traffic for intrusions **Show answer** **Answer: it manages maintenance work and asset history.** A computerized maintenance management system is the system of record for what was done, when, and by whom. Real-time control belongs to the BMS, and rack-level capacity tracking belongs to DCIM. [Preventive Maintenance Planning](https://datacentertraining.us/courses/preventive-maintenance-planning.html) covers CMMS use. 5. Question 5 Inherent availability is often estimated as MTBF / (MTBF + MTTR). What does shortening MTTR do? - Lowers availability - Raises availability, because each failure keeps the system down for less time - Has no effect, because only MTBF matters - Raises MTBF by the same amount **Show answer** **Answer: it raises availability.** MTBF is mean time between failures and MTTR is mean time to repair. With an MTBF of 10,000 hours, cutting MTTR from 10 hours to 2 hours lifts availability from about 99.90 to 99.98 percent, which is why on-site spares, clear EOPs, and trained staff matter. [Incident Response & Troubleshooting](https://datacentertraining.us/courses/incident-response-troubleshooting.html) covers faster recovery. 6. Question 6 What is the difference between RTO and RPO? - RTO is the maximum acceptable time to restore a service; RPO is the maximum acceptable data loss, measured as time since the last good copy - RTO is the maximum acceptable data loss; RPO is the time it takes to recover - Both measure how long the UPS batteries can carry the load - RTO applies to facility systems, while RPO applies only to networks **Show answer** **Answer: RTO is restore time; RPO is data loss.** An RPO of 15 minutes means backups or replication can never be more than 15 minutes behind. RTO drives recovery site and staffing decisions, while RPO drives backup and replication design. [Disaster Recovery & Business Continuity](https://datacentertraining.us/courses/disaster-recovery-business-continuity.html) covers both. 7. Question 7 Which system is built to monitor the electrical distribution system in detail, including power quality and breaker status, often with waveform capture? - BMS (building management system) - DCIM (data center infrastructure management) - CMMS (computerized maintenance management system) - EPMS (electrical power monitoring system) **Show answer** **Answer: the EPMS.** An EPMS reads meters, relays, and breaker trip units to capture power quality events and sequence-of-events data. A BMS monitors and controls mechanical systems like CRAHs, chillers, and pumps, and DCIM ties facility data to IT assets and capacity. [Monitoring, Automation & BMS Systems](https://datacentertraining.us/courses/monitoring-automation-bms-systems.html) compares the platforms. 8. Question 8 What is the best way to reduce alarm fatigue in a monitoring center? - Turn off any alarm that sounds more than once a day - Add louder alarm tones so operators pay attention - Rationalize alarms: tune setpoints and deadbands, set priorities, suppress follow-on alarms, and remove nuisance points - Send every alarm to email instead of the console **Show answer** **Answer: rationalize the alarms.** When operators see hundreds of low-value alarms, they start acknowledging without reading, and a critical one gets missed. Rationalization gives every alarm a cause, a priority, and a defined response. [DCIM Platform Fundamentals](https://datacentertraining.us/courses/dcim-platform-fundamentals.html) covers alarm management. 9. Question 9 After an incident is resolved, what is the goal of a root cause analysis (RCA)? - Identify which employee should be disciplined for the failure - Calculate the service credits owed to affected customers - Replace the failed part as quickly as possible and close the ticket - Find the underlying causes, often in process, design, or training, and set corrective actions that prevent a repeat **Show answer** **Answer: find underlying causes and prevent a repeat.** Methods like the 5 Whys and fishbone diagrams dig past "the breaker tripped" to why it tripped and why nobody caught it. A blameless approach gets honest answers, and corrective actions are tracked to closure. [Incident Response & Troubleshooting](https://datacentertraining.us/courses/incident-response-troubleshooting.html) covers RCA methods. 10. Question 10 What makes a good shift handoff in a 24/7 critical facility? - A structured turnover of active alarms, systems in abnormal or bypass states, work in progress, and planned work, written down and reviewed together - A quick verbal "all good" as the next shift walks in - Notes left in each technician's personal email - A formal handoff only when there is an active incident **Show answer** **Answer: a structured, written, face-to-face turnover.** Incidents can start when the incoming shift does not know a system was left in bypass or a valve was left closed. A written log plus a walk-through keeps that knowledge from leaving with the outgoing shift.
