across different environments.
B. To ensure interoperability, reliability, and security
of the system.
C. To develop, test, deploy, and
update each microservice independently, without affecting the rest of the
system.
D. To gain useful insights into the behavior of the
system.

that developers can use to solve complex computational problems in software
applications.

D. availability
========================================
09: Siobhan is developing an application that needs to use
an online calendar. What benefits would she gain from using an application API?
Select all that apply.
A. She needs to include all the calendar data in the
application.
B. She can use the calendar from her host operating
system.
C. She can access and use the
calendar functionality provided by a cloud service provider.
D. She doesn’t need to develop or
host her own calendar code.
=====================================
10: Which of the following is a benefit of microservices?
Select all that apply.
A. Developers can scale each
microservice up or down according to the demand and load, without impacting
other microservices.
B. Each microservice can handle
errors and failures gracefully, without causing the whole system to crash.
C. Developers can group microservices in clusters to work
together to provide the service or function.
D. They include an operating system alongside the code
that the service provides.
=================================
11: Why are containers fast to deploy and easy to update?
A. They run on any cloud platform
that supports them.
B. They use daemons.
C. There are tools available to orchestrate them.
D. They use the operating system of the host computer so
they don’t need to start an independent operating system.
===============================
12: Fill in the blank. __________ is a tool for
orchestrating multiple containers across different machines or clouds.
A. Podman
B. Virtual
machine
C. Docker
D.
Kubernetes
==============================

computer. <-- NO
B. A VM uses the physical computer’s virtual hardware.
C. VMs are software-based
emulations of a physical computer.
D. Only one VM per physical computer can run at a time.
===============================
14: You are part of an IT team tasked with using a container
to create and deploy your company’s new microservice. What is the correct order
of steps you should take to complete the deployment?

container image, publish the container, deploy the container
B. Write the code, test the image, create the container,
publish the container, deploy the container
C. Write the code, create the container, publish the
container, deploy the container, test the image
