Module 1

Question 1

What is cloud native?

Answer 1

Cloud-native is an approach to achieving goals that benefit everyone involved in developing, running, and managing
an application in the cloud.

Question 2

Goals of cloud-native

Answer 2

The goals of cloud-native are to adopt design patterns, paradigms, and techniques that enable loosely coupled
systems built around Microservice Architecture principals.

Question 3

Service meshes

Answer 3

are configurable infrastructure layers that describe how various services that comprise
an application communicate with each other.

Question 4

API Gateway technologies

Answer 4

s help formalize, configure, and secure the service endpoints into an
application.

Question 5

What is CI/CD?

Answer 5

It describes automation that emphasizes tooling around the code, build and deploy phases of
the software-development lifecycle.

Question 6

What is devsecops?

Answer 6

DevOps but with an additional focus on security and compliance.
DevSecOps builds on the cultural changes of DevOps to integrate the work of security teams sooner
rather than later.

Question 7

Cloud-native design

Answer 7

• Automated using Agile processes.
• Easily operable or manageable across multiple cloud environments.
• Observable at all application development lifecycle stages.
• Resilient to failures in production.

Question 8

Immutable infrastructure - i

Answer 8

• is a paradigm in which application images are never modified after they’re

Question 9

Web scale

Answer 9

is the seamless scaling of applications across cloud boundaries to meet consumer demands.

Question 10

Continuous integration

Answer 10

– describes the automated processes used to build, test, and merge application
code changes using source code control systems with integrated change management.

Question 11

Continuous delivery

Answer 11

describes the automated processes used to package and release application code.

Question 12

Continuous deployment

Answer 12

describes the automated processes used to deploy and orchestrate
applications to target cloud environments.

Question 13

Infrastructure-as-code (IaC)

Answer 13

are scripts and declarative configurations that describe the infrastructure
resources the application needs including servers, operating systems, storage, and network

Question 14

Test-Driven Development (TDD)

Answer 14

is when functional and unit tests are written first for a new feature or
change and then the actual code is written to pass it.

Question 15

Pair programming

Answer 15

– is when two developers work together and take turns where one developer writes
the code and the other one observes and warns of potential bugs or errors

Question 16

Mutation testing

Answer 16

– is a testing method to ensure code is resistant to casual or malicious changes that
have unforeseen impacts on the application.

Question 17

Site Reliability Engineering (SRE)

Answer 17

• is a practice that endorses the creation of reliability teams that are
  separate from the product delivery teams.

Question 18

Containers are a form of OS virtualization that can be run from which of the
following locations?

Answer 18

when the application
code is packaged in the standard way, can be run anywhere, be it a desktop,
traditional IT, or the cloud.

Question 19

DevOps brings together development and operations teams to overcome what
obstacles?

Answer 19

Configuration and deployment delays

Question 20

How does DevSecOps differ from DevOps?

Answer 20

It adds security and compliance into the development process.

Question 21

What does resiliency mean?

Answer 21

Quick recovery from unexpected failure.

Question 22

What is the meaning of the acronym SRE?

Answer 22

Site Reliability Engineering.

Question 23

What is the purpose of an SRE team?

Answer 23

Improve resiliency and reliability of applications.

Question 24

What does the acronym CI/CD mean?

Answer 24

Continuous Integration, Continuous Delivery/Deployment

Question 25

The goals of _________________ are to adopt design patterns, paradigms,
and techniques that enable loosely coupled systems build around
microservice architecture principles.

Answer 25

Cloud-native

Question 26

What is Mutation Testing?

Answer 26

Intentionally altering code to ensure unit testing is functioning.

Question 27

What does Cloud-native observability mean?

Answer 27

Deploy applications that are easier to monitor, upgrade and repair.
