A developer is writing a web application that will run on AWS Lambda. The application will give users the ability to log in to view private documents. All pages in the application must be designed to match the company's branding.
How can the developer host the sign-in pages with the LEAST amount of custom code?
To provide login functionality with branded sign-in pages and minimal custom code, the best solution is Amazon Cognito Hosted UI. Cognito User Pools include a managed authentication service that can handle sign-up/sign-in, MFA options, password resets, and OAuth/OpenID Connect flows. The Hosted UI provides ready-to-use authentication pages and endpoints, which removes the need to build and maintain custom authentication pages and backend logic.
AWS allows customization of the Hosted UI to match company branding (for example, logo, colors, and CSS styling). This directly meets the requirement that ''all pages must match branding'' while minimizing development effort. The application can integrate with Cognito using standard authorization flows and tokens, which works well with Lambda-based architectures (for example, API Gateway authorizers with Cognito user pools).
Option A (S3 static pages) would still require implementing authentication flows, session handling, token management, and secure integration with the backend---significantly more custom code.
Option B requires writing and maintaining custom sign-in page serving logic plus authentication handlers, which increases code and operational overhead.
Option C (Lambda@Edge) is even more complex, introducing edge execution and additional deployment/versioning considerations, and still requires custom auth logic.
Therefore, using Amazon Cognito User Pools with the Hosted UI and branding customization is the lowest-code, most maintainable solution.
A company is developing an application that will be accessed through the Amazon API Gateway REST API. Registered users should be the only ones who can access certain resources of this API. The token being used should expire automatically and needs to be refreshed periodically.
How can a developer meet these requirements?
A developer maintains a serverless application that uses an Amazon API Gateway REST API to invoke an AWS Lambda function by using a non-proxy integration. The Lambda function returns data, which is stored in Amazon DynamoDB.
Several application users begin to receive intermittent errors from the API. The developer examines Amazon CloudWatch Logs for the Lambda function and discovers several ProvisionedThroughputExceededException errors.
The developer needs to resolve the errors and ensure that the errors do not reoccur.
Comprehensive and Detailed Step-by-Step
Option A: Provisioned Capacity with Exponential Backoff:
Using provisioned capacity ensures sufficient throughput for the DynamoDB table.
Configuring the Lambda function to implement exponential backoff retries reduces the chance of exceeding capacity during peak usage.
This combination addresses the root cause (ProvisionedThroughputExceededException) and prevents errors without overprovisioning.
Why Other Options Are Incorrect:
Option B: Using SQS adds unnecessary latency and complexity. The issue lies in DynamoDB throughput, not request management.
Option C: A usage plan for the API does not address throughput issues in DynamoDB.
Option D: Invoking the Lambda function asynchronously does not resolve the DynamoDB capacity issue and might lead to delayed processing.
DynamoDB Provisioned Throughput Documentation
A developer has observed an increase in bugs in the AWS Lambda functions that a development team has deployed in its Node.js application.
To minimize these bugs, the developer wants to implement automated testing of Lambda functions in an environment that closely simulates the Lambda environment.
The developer needs to give other developers the ability to run the tests locally. The developer also needs to integrate the tests into the team's continuous integration and continuous delivery (CI/CD) pipeline before the AWS Cloud Development Kit (AWS CDK) deployment.
Which solution will meet these requirements?
The AWS Serverless Application Model Command Line Interface (AWS SAM CLI) is a command-line tool for local development and testing of Serverless applications3.Thesam local generate-eventcommand of AWS SAM CLI generates sample events for automated tests3.Thesam local invokecommand is used to invoke Lambda functions3. Therefore, option C is correct.
A developer compiles an AWS Lambda function and packages the result as a .zip file. The developer uses the Functions page on the Lambda console to attempt to upload the local packaged .zip file. When pushing the package to Lambda, the console returns the following error:
Which solutions can the developer use to publish the code? (Select TWO.)
