AWS DEV: Quizzes, Cheat Sheets, Flash Cards, Mock Exams, FAQs

1

Continuous integration
Continuous integration is a DevOps software development practice where developers regularly merge their code changes into a central repository, after which automated builds and tests are run. Continuous integration most often refers to the build or integration stage of the software release process and entails both an automation component (e.g. a CI or build service) and a cultural component (e.g. learning to integrate frequently).

You want to receive an email whenever a user pushes code to CodeCommit repository, how can you configure this?
Configure Notifications in the console, this will create a CloudWatch events rule to send a notification to a SNS topic which will trigger an email to be sent to the user.
Amazon SNS leverages the proven AWS cloud to dynamically scale with your application.

CloudFormation: Resources
The Resources section defines your resources you are provisioning. Outputs is used to output user defines data relating to the resources you have built and can also used as input to another CloudFormation stack. Transforms is used to reference code located in S3.

4

Which AWS service can be used to fully automate your entire release process?
AWS CodePipeline is a fully managed continuous delivery service that helps you automate your release pipelines for fast and reliable application and infrastructure updates

5

CloudFormation: Outputs
You want to use the output of your CloudFormation stack as input to another CloudFormation stack. Which sections of the CloudFormation template would you use to help you configure this?
Outputs is used to output user defines data relating to the resources you have built and can also used as input to another CloudFormation stack.

6

CloudFormation: Transforms
Transforms is used to reference code located in S3 and also specifying the use of the Serverless Application Model (SAM)for Lambda deployments.

7

CloudFormation: Nested Stacks
Nested stacks are stacks created as part of other stacks. You create a nested stack within another stack by using the AWS::CloudFormation::Stack resource. Using nested stacks to declare common components is considered a best practice.

8

Kinesis Data Streams
Kinesis Data Streams lets you order records and read and replay records in the same order to many Kinesis Data Streams applications. To enable write ordering, Kinesis Data Streams expects you to call the PutRecord API to write serially to a shard while using the sequenceNumberForOrdering parameter. Setting this parameter guarantees strictly increasing sequence numbers for puts from the same client and to the same partition key.Option A is correct as it cannot guarantee the ordering of records across multiple shards.

AWS AppSync
AWS AppSync simplifies application development by letting users create a flexible API to securely access, manipulate, and combine data from one or more data sources. AWS AppSync is a managed service that uses GraphQL to make it easy for applications to get the exact data they need. AWS AppSync allows users to build scalable applications, including those requiring real-time updates, on a range of data sources, including Amazon DynamoDB. In Amazon API Gateway, users can create a WebSocket API as a stateful frontend for an AWS service (such as AWS Lambda or DynamoDB) or for an HTTP endpoint. The WebSocket API invokes the backend based on the content of the messages it receives from client applications. Unlike a REST API, which receives and responds to requests, a WebSocket API supports two-way communication between client applications and the backend.

Amazon Cognito
Amazon Cognito adds user sign-up, sign-in, and access control to web and mobile applications quickly and easily. Users can also create an AWS Lambda function to make an API call to a custom analytics solution and then trigger that function with an Amazon Cognito post authentication trigger.
