Kubernetes Cloud Native Associate KCNA Certification Part
#1
1. What is the KCNA certification in the context of Kubernetes and Cloud Native?: A certification that provides a
broader learning path before moving to CKA and CKAD
2. What is the format of the KCNA exam?: Multiple Choice
3. How can one can reduce the overall cost of the KCNA exam?: By waiting for sales from the Linux Foundation
By attending KubeCon / CloudNativeCon and utilizing a post event discount
By checking for discount codes on the Linux Foundations' social media handles
4. Who proctors the KCNA exam when it is taken remotely?: A remote proctor who monitors your screen and
camera
5. What is the best place to check for any changes in the KCNA exam or curriculum?: GitHub (under
cncf/curriculum)
6. What does the KCNA curriculum include that is now a dedicated qualifica- tion?: GitOps and Prometheus
7. Who might be able to receive assistance for the KCNA exam from the LinuxFoundation or CNCF?:
People who are part of diversity groups
8. What is a key benefit of Open Standards in computing and software devel- opment?: They allow for the use of
multiple tools and technologies, avoiding vendor lock-in
9. What significant benefit do Open Standards provide in the field of com- puting?: They can be openly
adopted, implemented and further refined by any participant
10.Why is Docker a good example in understanding Open Standards?: Be- cause Docker has been instrumental
in the creation of Open Standards and Open Contributions
11.What specific software did Docker Inc donate to the Open Container Ini- tiative, marking the first OCI open
standard?: runC, Docker's underlying runtime software
12.Which specification outlines how a filesystem bundle should be packaged into an image?: Image Specification
13.What is the purpose of the Container Storage Interface (CSI)?: It is an open standard for interfacing with
storage solutions
14.What does the Container Runtime Interface (CRI) enable in the Kubernetes ecosystem?: It allows the kubelet
to use a wide variety of container runtimes
15.What specification does the Open Container Initiative outline for running a filesystem bundle?: Runtime
Specification
16.What open standard allows for the creation of OCI compliant container images?: OCI Image
Specification

17.What is the purpose of the Open Container Initiative's Distribution Spec- ification?: It defines a
specification on the open standards and API protocols for distribution of content
18.What is the reference implementation of the OCI runtime specification?: -
runc
19.What is a major challenge with monolithic applications?: Changes to one area can potentially affect the entire
application
20.In a Monolithic application, what issue can arise due to multiple applica- tions being dependent on the same
library?: Changing the library version for one application might negatively affect the other
21.What could the term "tight coupling" refer to in the context of monolithic applications?: A User Interface and
Business Logic are hard to work on separately
22.What is a significant advantage of microservices in cloud-native applica- tions?: They enhance flexibility and
make the application easier to manage
23.What is a significant advantage of using autoscaling in Cloud Native patterns?: It allows the application
to scale based on the workload at the time
24.What are the fundamental characteristics that define a Cloud Native Appli- cation?: Resiliency, Agility,
Operability and Maintainability
25.What does "Self Healing" refer to in the context of Cloud Native practices?-
: Architecting your application to automatically resolve issues and restart processes when they fail
26.What is the purpose of automation in a Cloud Native application?: To provide speed and agility through
automated processes that deploy infrastructure and applications rapidly and update frequently
27.Which automation tool is primarily focused on Infrastructure as Code (IAC)?: Terraform
28.How could Ansible facilitate Cloud Native automation?: Ansible is a toolset that could assist with many areas
including Container and Application Lifecycles as well as infrastructure deployment
29.Which of the following is a key function of Terraform in Cloud Native Automation?: Terraform focuses on
Infrastructure as Code (IAC), allowing for con- sistent, reproducible, and automated infrastructure across different
environments
30.In the context of CI/CD, what does "Continuous Integration" encourage?: It encourages developers to
frequently check in code and automatically test their projects prior to release
31.What best describes the concept of Continuous Delivery in the context of CI/CD?: A practice that encourages
that frequent development changes with an emphasis on automated testing, leading up to a releasable build

32.What does the term 'Continuous Deployment' mean in the context of CI/CD?: It refers to the practice
where changes are continuously deployed and released into a Production environment, often without requiring
human initiation
33.What is the zero trust security model in a Cloud Native context?: An environment that never trusts any
components and always verifies identities and integrity
34.What does the Cloud Native principle of "Speed, Efficiency and Cost Saving" promote?: Using autoscaling
to allow applications to scale up and down based on the workload, leveraging serverless architectures when needed,
and implementing proactive measures for cost saving
35.What is a key consideration when designing an application or infrastruc- ture in cloud native practices?:
Potential for component failure
36.How does the concept of 'Least Privilege' contribute to Cloud Native security?: It assigns the minimum set of
permissions needed to each component or user permission, limiting the potential damage from exploits and security
breaches
37.In the context of a Cloud Native ecosystem, what does "Secure by Default" mean?: Implementing secure
practices and leveraging processes and tools to en- sure components are secure from the start
38.What are Kubernetes "replicas" used for in the context of Self Healing?-
: Replicas are used to ensure a given number of instances of a deployment are running, and to replace any that fail, thereb
providing self-healing functionality
39. Which of the following options correctly lists the key pillars of Cloud Native Architecture?:
Microservices, Containers, DevOps, Continuous Delivery
40.Why is service discovery important in Cloud Native applications?: It allows for automatic detection of services
41.It prevents the use of Environment Variables and DNS services in Kuber- netes
Firewall rules and network ACLs: Environment Variables and built-in DNS
42.What does the term 'Auto' in Autoscaling refer to?: Auto for Automated or Automatic
43.What is Autoscaling?: A pattern to facilitate automatic scaling of infrastructure or application components
44.Which Autoscaling types reacts when metrics hit a given threshold?: Re- active Autoscaling
45.Which Autoscaling method could use AI and Machine Learning to scale in anticipation of demand?:
Predictive Autoscaling
46.What type of Autoscaling would an organization use if it knows its work- load is going to increase
exponentially at specific dates and times?: Scheduled Autoscaling
