ITIL4-CDS Create, Deliver and Support Practice Question
Exhibit
LOG_ENTRY: 2023-10-12 10:45:02 ERROR [Service_API] - CircuitBreaker 'PaymentGateway' state changed from CLOSED to OPEN due to threshold 0.85.
Refer to the exhibit. An IT operations team identifies this error log in the payment processing system. Which CDS concept is the team applying by using a circuit breaker pattern to prevent system-wide failure?
⚠ Common exam trap
Candidates often select 'Incident Management' or 'Availability Management', missing the broader overarching concept of system 'Resilience' demonstrated by automated failure mitigation patterns.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Resilience
The circuit breaker pattern is a classic application of 'Resilience' within the CDS framework. By monitoring failure thresholds, the system automatically prevents cascading failures by stopping calls to a failing service. This proactive management of service health ensures that the overall system remains available, reflecting the CDS priority of maintaining value delivery despite localized technical disruptions, thereby optimizing the total user experience during times of degradation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Continuous Integration
Why it's wrong here
Continuous Integration refers to the practice of merging development branches into a shared repository frequently to detect integration issues early. It focuses on the velocity and quality of code merges rather than the operational resilience or runtime protection of services in production.
- ✓
Resilience
Why this is correct
Resilience is the ability of a service to withstand and recover from failures while maintaining a minimum acceptable level of service. The circuit breaker pattern proactively stops requests to a failing component, preventing a total system crash and allowing the service to maintain stability.
- ✗
Shift-Left Testing
Why it's wrong here
Shift-left testing involves moving testing activities earlier in the development lifecycle to find defects sooner. While this improves overall software quality, it is a development-phase strategy and does not describe the runtime operational mechanism for mitigating failures in a live environment.
- ✗
Capacity Management
Why it's wrong here
Capacity Management ensures that the organization has the right amount of resources to meet agreed-upon service requirements. While it involves planning for usage spikes, it does not involve the dynamic, real-time automated circuit-breaking mechanisms used to manage component-level failures during operation.
