NEW QUESTION # 536
A developer is working on an application that uses a microservices architecture. The developer needs to grant an AWS Lambda function access to make calls to an Amazon API Gateway HTTP API. The HTTP API requires authentication.
Which solution will meet these requirements?
Answer: C
Explanation:
For service-to-service calls inside AWS, the simplest and most secure way to authenticate a caller (Lambda) to an API Gateway HTTP API is to use IAM authorization. When IAM auth is enabled on a route, API Gateway requires requests to be signed with AWS Signature Version 4 (SigV4). The calling Lambda function can sign the request using the AWS SDK (or SigV4 utilities) and its execution role credentials.
With this approach, you grant the Lambda function's execution role explicit permission to invoke the API by allowing the execute-api:Invoke action on the API's ARN. API Gateway then evaluates the SigV4-signed request against IAM to decide whether to authorize the call. This creates a clean, auditable permission model and avoids embedding static secrets.
Option A is incorrect and overly complex: JWT authorizers are typically used for end-user or workload identities from an OIDC/JWT provider; creating an IAM IdP is not how you enable JWT authorizers for HTTP APIs, and it does not directly solve Lambda-to-API authentication. Option C (API keys) is not considered an authentication mechanism for HTTP APIs in the same way; API keys are primarily for usage plans/throttling (and are more common with REST APIs). Storing an API key in environment variables is also weaker than IAM-based, short-lived credentials. Option D is backwards: a Lambda resource-based policy controls who can invoke the Lambda function, not who can call an API Gateway endpoint.
Therefore, B is the correct solution: enable IAM authorization on the HTTP API route and grant the Lambda function's IAM role permission to invoke the API (and sign requests with SigV4).
NEW QUESTION # 537
A developer is creating a mobile application that will not require users to log in.
What is the MOST efficient method to grant users access to AWS resources'?
Answer: B
Explanation:
This solution is the most efficient method to grant users access to AWS resources without requiring them to log in. Amazon Cognito is a service that provides user sign-up, sign-in, and access control for web and mobile applications. Amazon Cognito identity pools support both authenticated and unauthenticated users. Unauthenticated users receive access to your AWS resources even if they aren't logged in with any of your identity providers (IdPs). You can use Amazon Cognito to associate unauthenticated users with an IAM role that has limited access to resources, such as Amazon S3 buckets or DynamoDB tables. This degree of access is useful to display content to users before they log in or to allow them to perform certain actions without signing up. Using an identity provider to securely authenticate with the application will require users to log in, which does not meet the requirement. Creating an AWS Lambda function to create an IAM user when a user accesses the application will incur unnecessary costs and complexity, and may pose security risks if not implemented properly. Creating credentials using AWS KMS and applying them to users when using the application will also incur unnecessary costs and complexity, and may not provide fine-grained access control for resources.
NEW QUESTION # 538
A developer is creating AWS CloudFormation templates to manage an application's deployment in Amazon Elastic Container Service (Amazon ECS) through AWS CodeDeploy. The developer wants to automatically deploy new versions of the application to a percentage of users before the new version becomes available for all users.
How should the developer manage the deployment of the new version?
Answer: D
NEW QUESTION # 539
A developer is building an application that stores user activity data in an Amazon DynamoDB table. The developer is writing a new AWS Lambda function to process the activity data. The developer grants the IAM role that the function assumes permissions to query the table. The developer must ensure that the function does not have access to personally identifiable information (PII) that is stored in some of the table item attributes. Which solutions will meet these requirements? (Choose two.)
Answer: B,D
Explanation:
A DynamoDB resource-based policy can use fine-grained access-control conditions to deny retrieval of specified PII attributes, enforcing the restriction at the service level.
Client-side envelope encryption can encrypt only the PII attributes with a customer managed KMS key. By withholding decrypt permission from the Lambda function's execution role, the function cannot access the plaintext PII even when it retrieves the table items.
NEW QUESTION # 540
An application includes an Amazon DynamoDB table that is named orders. The table has a primary partition key of id and a global secondary index (GSI) that is named an accountIndex.
The GSI has a partition key of accountId and a sort key of orderDateTime.
A developer needs to create an AWS Lambda function to retrieve the orders that have an accountId of 100.
Which solution will meet this requirement by using the LEAST read capacity?
Answer: D
Explanation:
The Query action is the most efficient choice for this scenario. It retrieves items from a table or index based on the specified partition key (accountId) and can optionally use the sort key (orderDateTime) for additional filtering. By querying the accountIndex GSI with a KeyConditionExpression, you directly retrieve only the relevant items without scanning unnecessary data, minimizing read capacity usage.
