Amazon AWS Certified Developer - Associate Sample Questions (Q281-Q286):

NEW QUESTION # 281
A company has deployed an application on AWS Elastic Beanstalk. The company has configured the Auto Scaling group that is associated with the Elastic Beanstalk environment to have five Amazon EC2 instances.
If the capacity is fewer than four EC2 instances during the deployment, application performance degrades.
The company is using the all-at-once deployment policy.
What is the MOST cost-effective way to solve the deployment issue?

A. Change the Auto Scaling group to six desired instances.
B. Change the deployment policy to traffic splitting. Specify an evaluation time of 1 hour.
C. Change the deployment policy to rolling. Specify a batch size of 2.
D. Change the deployment policy to rolling with additional batch. Specify a batch size of 1.

Answer: D

Explanation:
Explanation
This solution will solve the deployment issue by deploying the new version of the application to one new EC2 instance at a time, while keeping the old version running on the existing instances. This way, there will always be at least four instances serving traffic during the deployment, and no downtime or performance degradation will occur. Option A is not optimal because it will increase the cost of running the Elastic Beanstalk environment without solving the deployment issue. Option B is not optimal because it will split the traffic between two versions of the application, which may cause inconsistency and confusion for the customers. Option D is not optimal because it will deploy the new version of the application to two existing instances at a time, which may reduce the capacity below four instances during the deployment.

NEW QUESTION # 282
A developer is building a web application that uses Amazon API Gateway to expose an AWS Lambda function to process requests from clients. During testing, the developer notices that the API Gateway times out even though the Lambda function finishes under the set time limit.
Which of the following API Gateway metrics in Amazon CloudWatch can help the developer troubleshoot the issue? (Choose two.)

A. Count
B. IntegrationLatency
C. Latency
D. CacheMissCount
E. CacheHitCount

Answer: B,C

Explanation:
Amazon API Gateway is a service that enables developers to create, publish, maintain, monitor, and secure APIs at any scale. Amazon CloudWatch is a service that monitors AWS resources and applications. API Gateway provides several CloudWatch metrics to help developers troubleshoot issues with their APIs. Two of the metrics that can help the developer troubleshoot the issue of API Gateway timing out are:
IntegrationLatency: This metric measures the time between when API Gateway relays a request to the backend and when it receives a response from the backend. A high value for this metric indicates that the backend is taking too long to respond and may cause API Gateway to time out.
Latency: This metric measures the time between when API Gateway receives a request from a client and when it returns a response to the client. A high value for this metric indicates that either the integration latency is high or API Gateway is taking too long to process the request or response.

NEW QUESTION # 283
A banking company is building an application for users to create accounts, view balances, and review recent transactions. The company integrated an Amazon API Gateway REST API with AWS Lambda functions. The company wants to deploy a new version of a Lambda function that gives customers the ability to view their balances. The new version of the function displays customer transaction insights.
The company wants to test the new version with a small group of users before deciding whether to make the feature available for all users. Which solution will meet these requirements with the LEAST disruption to users?

A. Redeploy the REST API stage to use the new version of the function. If issues are detected, update the REST API to point to the previous version of the function.
B. Create a new REST API stage for the new version of the function. Create a weighted alias record set in Amazon Route 53 to distribute traffic between the original stage and the new stage.
C. Deploy the new version of the function to a new stage in the REST API. Route traffic to the new stage.
If the new version fails, route traffic to the original stage.
D. Create a canary deployment for the REST API. Gradually increase traffic to the new version of the function. Revert traffic to the old version if issues are detected.

Answer: D

Explanation:
API Gateway'scanary deploymentsallow gradual traffic shifting to a new version of a function, minimizing disruption while testing.
* Why Option A is Correct:
* Gradual Rollout: Reduces risk by incrementally increasing traffic.
* Rollback Support: Canary deployments make it easy to revert to the previous version.
* Why Not Other Options:
* Option B: Redeploying the stage disrupts all users.
* Option C & D: Managing new stages and weighted routing introduces unnecessary complexity.
References:
* Canary Deployments in API Gateway

NEW QUESTION # 284
A developer creates an Amazon DynamoDB table. The table has OrderID as the partition key and NumberOfItemsPurchased as the sort key. The data type of the partition key and the sort key is Number.
When the developer queries the table, the results are sorted by NumberOfItemsPurchased in ascending order. The developer needs the query results to be sorted by NumberOfItemsPurchased in descending order.
Which solution will meet this requirement?

A. Create a local secondary index (LSI) on the NumberOfItemsPurchased sort key.
B. In the Query operation, set the ScanIndexForward parameter to false.
C. In the Query operation, set the KeyConditionExpression parameter to false.
D. Change the sort key from NumberOfItemsPurchased to NumberOfItemsPurchasedDescending.

Answer: B

NEW QUESTION # 285
A company has developed an application that uses AWS Lambda functions to process messages from an Amazon SQS queue. One of the Lambda functions makes a call to an external API that is expected to encounter temporary service unavailability.
A developer needs to configure the function to retry failed messages from an Amazon SQS dead-letter queue. The developer notices that the Lambda function is re-processing some messages in the queue more than once.
Which solution will resolve this issue?

A. Set the delivery delay parameter at the queue level. Configure the Lambda function to delete processed messages from the queue.
B. Set a message retention period for each message. Configure the Lambda function to add a MessageId to each message.
C. Set a receive message wait time for each message. Configure the Lambda function to add a MessageId to each message.
D. Set the visibility timeout parameter at the queue level. Configure the Lambda function to delete processed messages from the queue.

Answer: D

Explanation:
Comprehensive Detailed Explanation with all AWS Reference
Why Option B is Correct:
Setting the visibility timeout ensures that once a message is being processed, it is temporarily hidden from other consumers. The Lambda function must delete processed messages to avoid re-processing when the visibility timeout expires.
Why Other Options are Incorrect:
Option A: Message retention affects how long messages stay in the queue, not how they are processed.
Option C: Receive message wait time optimizes long polling but does not prevent re-processing.
Option D: Delivery delay introduces latency for new messages and does not address message re-processing.

Using SQS Visibility Timeout
