This KCNA practice question tests your understanding of cloud native architecture. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are core principles of cloud native architecture? (Choose two.)
Manual infrastructure provisioning
Why wrong: Cloud native emphasizes automation.
Monolithic application design
Why wrong: Monolithic design is the opposite of cloud native.
Tight coupling between services
Why wrong: Coupling is avoided in cloud native.
Containerization
Containers provide lightweight, consistent environments.
Microservices
Microservices enable independent scaling and deployment.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Containerization
Containerization (Option D) is a core principle of cloud native architecture because it packages applications and their dependencies into isolated, lightweight containers, enabling consistent deployment across environments and efficient resource utilization. This aligns with the cloud native goal of portability and scalability, as containers can be orchestrated by platforms like Kubernetes to manage dynamic workloads.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Manual infrastructure provisioning

Common exam traps
CNCF often tests the misconception that cloud native architecture requires a specific technology like Kubernetes or Docker, but the core principles are about architectural patterns (e.g., microservices, containerization) rather than any single tool, so candidates may incorrectly select options that describe operational practices (like manual provisioning) instead of architectural principles.
Detailed technical explanation
Under the hood, containerization leverages Linux kernel features like cgroups for resource limits and namespaces for process isolation, enabling multiple containers to share a host OS without conflict. In real-world scenarios, this allows a microservice to be updated or scaled independently without affecting others, as each container runs its own filesystem and network stack, reducing deployment friction and improving fault tolerance.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
