Amazon AWS Certified Developer - Associate Sample Questions (Q471-Q476):

NEW QUESTION # 471
A developer created an AWS Lambda function that accesses resources in a VPC. The Lambda function polls an Amazon Simple Queue Service (Amazon SQS) queue for new messages through a VPC endpoint. Then the function calculates a rolling average of the numeric values that are contained in the messages. After initial tests of the Lambda function, the developer found that the value of the rolling average that the function returned was not accurate.
How can the developer ensure that the function calculates an accurate rolling average?

Answer: D

Explanation:
Modify the function to store the values in Amazon ElastiCache. When the function initializes, use the previous values from the cache to calculate the rolling average.


NEW QUESTION # 472
A developer is building an application that uses an Amazon SQS queue and an AWS Lambda function that consumes messages from the SQS queue. When the function processes a message, the function sometimes sends a duplicate message to the source queue. The developer notices that some of the duplicate messages are lost from the queue without being processed. The developer must ensure that all messages are processed.
Which solution will meet this requirement?

Answer: A

Explanation:
Option C is correct because Lambda has recursive loop detection for supported event chains, including Lambda with Amazon SQS. By default, Lambda can stop invocations when it detects a recursive loop, which can explain why duplicate messages sent back to the same source queue are not processed. AWS documentation states that Lambda detects recursive loops involving Amazon SQS and, by default, terminates invocations when the loop threshold is reached. The Lambda recursion configuration can be changed to Allow, in which case Lambda does not take action when it detects the function being invoked as part of a recursive loop. Increasing batch size does not address dropped recursive invocations. The SQS queue does not directly invoke Lambda by permission in this pattern; Lambda polls SQS through the event source mapping.
Visibility timeout addresses reappearance timing, not recursive-loop termination.


NEW QUESTION # 473
A company is using Amazon API Gateway to invoke a new AWS Lambda function. The company has Lambda function versions in its PROD and DEV environments. In each environment, there is a Lambda function alias pointing to the corresponding Lambda function version. API Gateway has one stage that is configured to point at the PROD alias.
The company wants to configure API Gateway to enable the PROD and DEV Lambda function versions to be simultaneously and distinctly available.
Which solution will meet these requirements?

Answer: C

NEW QUESTION # 474
A developer is building a microservices-based application by using Python on AWS and several AWS services The developer must use AWS X-Ray The developer views the service map by using the console to view the service dependencies. During testing, the developer notices that some services are missing from the service map What can the developer do to ensure that all services appear in the X-Ray service map?

Answer: A

Explanation:
AWS X-Ray SDK: The primary way to enable X-Ray tracing within applications. The SDK sends data about requests and subsegments to the X-Ray daemon for service map generation.
Instrumenting All Services: To visualize a complete microservice architecture on the service map, each relevant service must include the X-Ray SDK.
Reference:
AWS X-Ray Documentation: https://docs.aws.amazon.com/xray/
X-Ray SDK for Python: https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-python.html


NEW QUESTION # 475
A developer has created a repository in AWS CodeArtifact. The development team needs to receive notifications when new packages are published to the repository.
Which solution will meet this requirement with the LEAST operational overhead?

Answer: C

Explanation:
AWS CodeArtifact emits events when repository actions occur, such as publishing a new package. AWS documentation recommends Amazon EventBridge as the native service for routing AWS service events to targets with minimal configuration and no infrastructure to manage.
By creating an EventBridge rule that matches CodeArtifact package publication events and routing those events directly to an Amazon SNS topic, the developer can notify the team immediately. SNS provides built- in email subscriptions, retries, and delivery guarantees without custom code.
Option C is the most operationally efficient because it uses fully managed, serverless services and requires no custom compute, code maintenance, or orchestration. EventBridge directly supports SNS as a target, making the configuration straightforward.
Option A is invalid because CodeArtifact does not directly publish notifications to SNS topics. Options B and D introduce unnecessary complexity by adding Lambda or Step Functions and Amazon SES, increasing operational overhead without added value.
Therefore, using EventBridge to route CodeArtifact events to SNS is the AWS-recommended and simplest solution.
