100+ Free ITIL 4 MEM Practice Questions

The ITIL 4 MEM exam has 40 multiple-choice (Objective Test Question) items to be completed in 60 minutes. The pass mark is 70% — at least 28 correct answers out of 40. The exam is closed-book, with only provided materials permitted. Non-native English speakers receive 75 minutes (25% extra). The exam is delivered online through PeopleCert proctoring or at authorized test centers.

ITIL 4 Foundation certification is a mandatory prerequisite. Foundation establishes the SVS, Four Dimensions, Service Value Chain, Guiding Principles, and the 34 ITIL Practices that MEM builds on. Practical experience in monitoring, SRE, NOC operations, or service operations is recommended but not required.

An event is any change of state that has significance for the management of a service or other configuration item — most events are informational and require no action. An alert is a notification that a threshold has been reached, something has changed, or a failure has occurred — it requires human or automated attention. An incident is an unplanned interruption to a service, or a reduction in the quality of a service. Exception events frequently trigger alerts, and many alerts result in incident records.

Core topics include: MEM purpose and key activities; event categories (informational, warning, exception); active vs passive and reactive vs proactive monitoring; monitoring sources (infrastructure, APM, database, network, RUM, logs, business KPIs, cloud-native); the three pillars of observability (metrics, logs, traces); distributed tracing with OpenTelemetry, Jaeger, and Zipkin; the USE method (Utilization, Saturation, Errors) and RED method (Rate, Errors, Duration); Google SRE's Four Golden Signals (Latency, Traffic, Errors, Saturation); AIOps correlation and noise reduction; thresholds and alert routing; and integration with Incident, Problem, Service Continuity, and Capacity and Performance Management.

Most candidates need 25-35 hours of study, assuming current ITIL 4 Foundation knowledge. Recommended path: 1) Review ITIL 4 Foundation concepts (SVS, Four Dimensions, Practices); 2) Master event categories and the event vs alert vs incident distinction; 3) Learn the monitoring types, sources, and observability pillars; 4) Study USE, RED, Four Golden Signals, and AIOps; 5) Take 2-3 timed mock exams scoring 80%+ before scheduling.

The USE method (Brendan Gregg) is applied to resources and measures Utilization, Saturation, and Errors — best for infrastructure (CPU, memory, disk, network). The RED method (Tom Wilkie) is applied to request-driven services and measures Rate, Errors, and Duration — best for microservices and APIs. Google SRE's Four Golden Signals — Latency, Traffic, Errors, Saturation — apply to user-facing services and synthesize both perspectives. ITIL 4 MEM expects candidates to know when each model applies.
