Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The kube-apiserver etcd storage backend encryption key
Why it's wrong here
Etcd encryption protects API data at rest, not ingress proxy traffic.
- ✗
The coreDNS server managing TLS private keys
Why it's wrong here
CoreDNS resolves domain names, it does not manage Ingress TLS keys.
- ✗
The persistent volume CSI controller
Why it's wrong here
CSI controllers handle storage volumes, not ingress HTTP routing.
- ✓
The Ingress resource object defining routing rules and TLS hosts
Why this is correct
The Ingress resource specifies the routing rules, hostnames, and TLS secret mappings.
- ✓
The Ingress Controller pod implementing the reverse proxy logic
Why this is correct
The Ingress Controller reads the Ingress resource and proxies traffic accordingly.
