Question 2
ObservabilityWhich CNCF project handles logging?
Correct answer: B

Why each option is right or wrong
A. Prometheus
B. Fluentd
CNCF lists Fluentd as the graduated project for log collection and forwarding, and it is the component in the cloud-native stack specifically designed to aggregate, parse, and route log records from containers and hosts. By contrast, projects like Prometheus and Fluent Bit are oriented to metrics or lightweight log forwarding, so the logging-focused CNCF project identified here is Fluentd.
C. Envoy
D. Kubectl
