KCNA Container Orchestration Practice Question
Which TWO of the following are benefits of using a container orchestration platform like Kubernetes? (Select 2)
⚠ Common exam trap
CNCF often tests the distinction between 'benefits' and 'basic features'—candidates may incorrectly select manual scaling (B) as a benefit, but the exam expects you to recognize that automation (C) and high availability (E) are the true advantages of orchestration platforms.
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
✓
Automated scaling based on demand
Kubernetes includes a Horizontal Pod Autoscaler (HPA) that automatically adjusts the number of pod replicas based on observed CPU, memory, or custom metrics. This enables applications to scale out during traffic spikes and scale in during low demand, improving resource utilization and responsiveness without manual intervention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Single-node deployment for simplicity
Why it's wrong here
Orchestration is for multi-node clusters.
- ✗
Manual scaling of applications
Why it's wrong here
Orchestration supports automatic scaling.
- ✓
Automated scaling based on demand
Why this is correct
Horizontal Pod Autoscaler scales replicas automatically.
- ✗
Elimination of all application bugs
Why it's wrong here
Orchestration does not fix bugs.
- ✓
High availability through automated failover
Why this is correct
Kubernetes automatically reschedules failed containers.
