A team is building a new cloud native application. They have a requirement that the system must remain available even if an entire availability zone fails. They also want to minimize the cost of running the application. Which approach best balances these two constraints?

Deploy the application in a single availability zone with a standby replica in another zone.

Deploy the application in multiple regions with active-passive failover.

Deploy the application on a single, large instance in one availability zone.

Deploy the application across multiple availability zones with active-active load balancing.

Which statement best describes cloud native computing as defined by the CNCF?

An approach to building and running applications that exploits the advantages of the cloud computing delivery model

A method for migrating legacy monolithic applications to a single large virtual machine

A deployment model that requires applications to run exclusively on public cloud infrastructure

A specific programming language or framework required for all cloud applications

A developer is evaluating open-source projects to build a cloud native platform. They want to ensure the projects they choose are well-governed and widely adopted. Which organization should they look to for guidance and a curated landscape of projects?

The Internet Engineering Task Force (IETF).

The Cloud Native Computing Foundation (CNCF).

The Open Container Initiative (OCI).

The World Wide Web Consortium (W3C).

A team is building a cloud native application and wants to ensure it can handle sudden spikes in traffic without manual intervention. They are considering using Kubernetes with Horizontal Pod Autoscaling (HPA). What is a critical requirement for HPA to work effectively?

The application must be deployed as a single, large pod.

The application must expose metrics that HPA can consume, such as CPU utilization or custom metrics.

The application must be deployed in a single availability zone.

The application must be stateless and store all data in memory.

Part of the Cloud Native Architecture domain, which accounts for 12% of the KCNA exam. Linux Foundation does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 2–4 from this objective — we provide 29 practice questions to prepare you well beyond it.
