A. scalability

B. reusability

C. reliability

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

==============================

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?
