CLF-C02 - Cloud Technology and Services (34% of the exam) - Section 3.1

Define methods of deploying and operating in the AWS Cloud, choosing between programmatic access, the AWS Management Console and infrastructure as code, and identifying cloud, hybrid and on-premises deployment models.

Define the three main methods of interacting with AWS - the Management Console, the AWS CLI for programmatic access, and infrastructure as code tools such as AWS CloudFormation - and identify when each is appropriate. Distinguish cloud-only, hybrid, and on-premises deployment models, and recognise the trade-offs each involves.

An operations team wants to provision AWS resources in a non-interactive, repeatable way that can be saved in files and re-run from an automated build job, with no person clicking through a graphical interface. Which TWO methods of working with AWS support this scripted, repeatable approach? (Select TWO.)

AThe AWS Command Line Interface, which issues service commands from a terminal that scripts can call and re-run. Correct
BInfrastructure as code with AWS CloudFormation, which provisions resources from a declarative template file. Correct
CThe AWS Management Console, which is a web interface where a person points and clicks to configure resources.
DAmazon CloudWatch, which collects metrics and logs so teams can monitor how their running resources behave.
EAWS Trusted Advisor, which inspects an account and recommends improvements to cost, security and performance.

The AWS CLI and infrastructure as code both let teams provision AWS resources from saved, re-runnable definitions, unlike the manual point-and-click Management Console. Both the AWS CLI and infrastructure as code express AWS actions as text that can be stored in version control and replayed by an automated pipeline, so each run produces the same result without manual clicks. The Management Console is interactive and manual, while CloudWatch and Trusted Advisor observe or advise on resources rather than create them.

Why A is correct: The AWS CLI runs commands from a terminal, so scripts can invoke and repeat them as part of an automated job.

Why B is correct: CloudFormation provisions resources from a saved template, giving the repeatable, file-driven approach the team wants.

Why C is wrong: The console is a manual graphical interface, so it does not give the scripted, re-runnable provisioning the team needs.

Why D is wrong: CloudWatch monitors resources after they exist and is not a method for provisioning them from scripts or files.

Why E is wrong: Trusted Advisor only advises on an existing account and cannot provision resources from a repeatable file or script.

Exam traps in Cloud Technology and Services

Answers that look right on this material and are not. Each one is a distractor from a different question in the CLF-C02 bank for this domain.

In an on-premises model, all servers and storage are owned and run by AWS inside its Regions on the company's behalf.
Why it is wrong: On-premises means the company runs hardware in its own data centre, so describing it as AWS-run inside Regions is wrong.
A cloud deployment model, where every part of the application is built and run entirely on AWS with no on-premises infrastructure
Why it is wrong: An all cloud model runs nothing on-premises, so it contradicts the requirement to keep sensitive workloads in the company data centre.
The AWS Management Console, the web-based graphical interface used to view and adjust resources by hand.
Why it is wrong: The console is a point-and-click web interface for manual work, so it cannot be embedded inside a Java program to make AWS calls from within the application logic.
