How should I use these Cloud Native Architecture practice questions?

Read each scenario carefully and choose your answer before revealing the explanation. Then check why your choice was right or wrong. Repeat until the reasoning feels automatic.

Can I practise just Cloud Native Architecture questions in a focused session?

Yes — use the session launcher on this page to start a 10-, 20-, 30- or 50-question session drawn entirely from the Cloud Native Architecture domain.

Cloud Native Architecture practice questions

Practise KCNA NAT and PAT questions covering address translation types, inside/outside interface roles, static vs dynamic vs PAT, and troubleshooting missing or incorrect translations.

Courseiva uses original exam-style practice questions designed for learning and revision. The goal is to understand the concepts, recognise exam patterns, and improve through explanations — not memorise copied exam dumps.

What the exam tests

What to know about Cloud Native Architecture

Cloud concepts questions usually test the service model (IaaS/PaaS/SaaS) and deployment model (public/private/hybrid/community) appropriate for a given scenario.

IaaS, PaaS and SaaS responsibilities and examples.

Public, private, hybrid and community cloud deployment models.

On-premises vs cloud trade-offs: cost, control, scalability.

How cloud connectivity options (VPN, Direct Connect, ExpressRoute) work.

Why learners struggle

Why Cloud Native Architecture questions are commonly missed

NAT questions are missed when learners confuse the four address types (inside local, inside global, outside local, outside global) or misapply the interface direction. A translation rule can look correct but still fail if the ACL, interface, or direction is wrong.

·Inside local vs inside global — inside local is the private source, inside global is the translated public address
·PAT overloads — many sources share one public IP using unique port numbers
·Interface direction — ip nat inside and ip nat outside must be on the correct interfaces
·Static NAT vs dynamic NAT vs PAT — each serves a different use case
·The NAT ACL identifies traffic to translate, not traffic to permit or deny
·A missing translation can look like a routing problem if the interfaces are misconfigured

Watch out for

Common Cloud Native Architecture exam traps

▸IaaS gives you infrastructure control; SaaS gives you only the application.
▸Hybrid cloud combines on-premises and public cloud — not two public clouds.
▸Cloud does not automatically mean cheaper or more secure.
▸Management responsibility shifts with each service model (IaaS → PaaS → SaaS).

Cloud Native Architecture questions

A cloud-native application is designed with multiple microservices that need to handle a sudden spike in traffic without manual intervention. Which Kubernetes feature best enables this?

A team is designing a cloud-native system that must maintain high availability across multiple cloud regions. The application uses Kubernetes clusters in each region. Which approach best ensures that the system can tolerate a full region failure while minimizing complexity?

A microservice logs errors when connecting to the database. The logs show 'connection refused'. Which troubleshooting step should be taken first?

Which practice is a key principle of cloud-native architecture?

A cloud-native application uses a service mesh (Istio) for traffic management. The team notices increased latency in inter-service communication. Which likely cause should be investigated first?

A team is designing a cloud-native application that requires each microservice to have its own database. This pattern is known as:

Which resource in Kubernetes is used to expose a set of pods as a network service?

A cloud-native application experiences periodic timeouts when calling a downstream service. The downstream service is running in the same Kubernetes cluster. Which design pattern should be implemented to handle this gracefully?

Which TWO statements are true about cloud-native architecture?

Which TWO are benefits of using a service mesh in cloud-native applications?

Which THREE are core principles of the Twelve-Factor App methodology?

Which THREE are typical characteristics of a cloud-native application?

A development team is containerizing a monolithic application into microservices. Which practice aligns with cloud-native architecture principles?

An organization wants to adopt a cloud-native approach for its new application. Which characteristic is most important for the application to be considered cloud-native?

A team is migrating a legacy application to Kubernetes. The application requires persistent storage and needs to maintain session affinity. Which set of Kubernetes resources should they use?

Which TWO practices are recommended for designing cloud-native microservices? (Choose 2)
