Question 1 of 30

A critical incident has arisen following the deployment of a new microservice, characterized by unpredictable latency spikes and intermittent connection failures impacting end-users. The DevOps team is tasked with resolving this with extreme urgency. Which of the following approaches best balances immediate stability with thorough root cause analysis, adhering to principles of effective incident response and technical problem-solving under pressure?

Implement a feature flag to disable specific functionalities of the new microservice, allowing for continued operation of unaffected components, while simultaneously initiating a deep dive into the service's logs, AWS resource metrics, and configuration settings to pinpoint the root cause.

Immediately initiate a full rollback of the new microservice to the previous stable version, and then conduct a post-mortem analysis of the failed deployment to understand the underlying issues.

Scale up all associated AWS resources, such as EC2 instances and RDS read replicas, in an attempt to absorb the increased load, and monitor the system for stabilization before further investigation.

Notify stakeholders of a critical system failure, instruct all team members to cease all other work and focus solely on analyzing the new microservice's code for bugs, without altering the production environment.
