Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Kubernetes: Container orchestration
Why this is correct
Kubernetes is the leading container orchestration platform for automating deployment, scaling, and management of containerized applications.
Prometheus: Log collection
Why it's wrong here
Incorrect — Prometheus is a monitoring and alerting toolkit, not a log collector. Log collection is typically done by Fluentd or similar.
Envoy: Service proxy and load balancing
Why this is correct
Envoy is a high-performance L7 proxy and load balancer designed for service mesh architectures.
CoreDNS: Monitoring and alerting
Why it's wrong here
Incorrect — CoreDNS is a DNS server for service discovery, not for monitoring and alerting. Prometheus handles that.
Fluentd: Log collection
Why this is correct
Fluentd is a data collector for unified logging layer, capable of collecting and forwarding logs.
