Question 1

The systems development cycle has six phases. The first three phases are plan, define, and design. What are the last three phases of the SDLC?

Code, build, and maintain
Test, deploy, and maintain
Develop, deploy, and maintain
Code, build, and test

In the develop phase, developers write, build, and test code. The deploy phase focuses on deploying code to production environments. The maintain phase focuses on monitoring code that's in production.

Question 2

Which task is performed during the develop stage of the systems development cycle?

Deficiencies are identified.
New components are obtained and installed.
New system requirements are defined.
The system is put into use.

In the develop phase, a new system is developed, new components are obtained and installed, system users are trained, and all aspects of the system's performance is tested.

Question 3

A systems administrator must grant a new developer permissions that are associated with the developer role. This role is associated with the developer group. Which AWS service should the administrator use to assign the new developer to the developer group?

AWS Resource Access Manager
AWS IAM
Amazon EC2
Amazon S3

IAM is used to grant permissions to users based on user, group, role, and policies.

Question 4

Which of the following is an important benefit of AWS CloudShell?

Users get 500 MB of storage per region.
You manually patch and update the environment.
It inherits your credentials from the AWS Management Console.
You pay up front for reserved blocks of time and capacity.

CloudShell inherits your credentials from the AWS Management Console. This means there are not key files to manage when using the AWS CLI.

Question 5

What are three ways to interact with AWS APIs. (Select three.)

AWS Management Console
AWS IAM
AWS SDKs
AWS CLI
AWS CloudTrail
AWS X-Ray

Each user interaction with an AWS service makes an API call. Users interact with AWS service APIs through the AWS Management Console, by using an AWS SDK, or through the AWS CLI.

Question 6

Which tool enables users to control their AWS services from the command line and automate service management with scripts?

AWS Identity and Access Management (IAM)
AWS Tools for PowerShell
AWS X-Ray
Amazon Q Developer

AWS Tools for PowerShell enables users to control their AWS services from the command line and automate service management with scripts.

Question 7

What is Amazon Q Developer?

A cloud-based integrated development environment (IDE)
A generative AI-powered coding assistant
A browser-based CLI
A wizard that leads you through the steps to configure your integrated development environment (IDE)

Amazon Q Developer uses generative AI to accelerate coding tasks. For example, Amazon Q Developer can chat about code, provide in-line code completions, generate new code, and scan your code for security vulnerabilities.

Question 8

Which statements describe AWS resource APIs? (Select two.)

They have at least one class per conceptual resource.
They provide a lower level abstraction than the higher level calls made by service client APIs.
They provide a higher level of abstraction than the low level calls made by service client APIs.
They have objects for request and result.
They provide access to resources through objects and collections.

Incorrect - Service client APIs provide a lower-level abstraction than the higher-level calls made by resource APIs. Service client objects represent the request parameters and the response data. Resource APIs have one class per conceptual resource.

Question 9

A developer is using the AWS SDK for Python and must specify the Region. Which method enables the developer specify the Region?

By associating a default Region with their profile in the credentials file in the dot AWS folder within their home folder (The Region goes in the config file not the credentials file. None of the answers are correct.)
Users cannot specify the AWS Region in the service client.
By setting the AWS underscore profile environment variable
By setting the Region when they instantiate the service

Users can set the Region when they instantiate the service client, by setting the AWS_DEFAULT_REGION environment variable, or by setting the default Region in the AWS shared configuration file.

Question 10

Developer makes an API call to access an Amazon S3 bucket that doesn’t exist. Which HTTP response code does the developer receive from the AWS

400 series
200 series
300 series
500 series

A 400-series response code means that the application has an error that the developer must address.
