KCNA Container Orchestration Practice Question
Which TWO are benefits of using a container orchestration platform like Kubernetes? (Select TWO.)
⚠ Common exam trap
CNCF often tests the distinction between manual and automatic scaling; candidates may incorrectly select manual scaling as a benefit because they confuse it with the ability to scale, but the question asks for benefits of using the platform, which include automation, not manual effort.
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
✓
Automatic service discovery and load balancing
Kubernetes includes built-in service discovery and load balancing. Services in Kubernetes get a stable virtual IP and DNS name, and kube-proxy implements load balancing across pods using iptables or IPVS rules, distributing traffic without manual configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increases application complexity
Why it's wrong here
Orchestration aims to simplify management, not increase complexity.
- ✗
Requires a dedicated hypervisor for each container
Why it's wrong here
Containers run on the host kernel; no hypervisor needed.
- ✓
Automatic service discovery and load balancing
Why this is correct
Kubernetes automatically assigns IPs and a single DNS name for a set of pods and load-balances traffic.
- ✓
Self-healing (automatic restart of failed containers)
Why this is correct
Kubernetes automatically restarts containers that fail and replaces pods on failed nodes.
- ✗
Manual scaling of applications
Why it's wrong here
Orchestration automates scaling, not manual.
