질문 # 333
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.

A. Update the REST API to send requests on an Amazon SQS queue. Configure the Lambda function to process requests from the queue.
B. Update the REST API to invoke the Lambda function asynchronously.
C. Configure a usage plan for the REST API.
D. Use provisioned capacity mode for the DynamoDB table, and assign sufficient capacity units. Configure the Lambda function to retry requests with exponential backoff.

정답：D

설명：
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.

질문 # 334
A company's developer has deployed an application in AWS by using AWS CloudFormation The CloudFormation stack includes parameters in AWS Systems Manager Parameter Store that the application uses as configuration settings. The application can modify the parameter values When the developer updated the stack to create additional resources with tags, the developer noted that the parameter values were reset and that the values ignored the latest changes made by the application. The developer needs to change the way the company deploys the CloudFormation stack. The developer also needs to avoid resetting the parameter values outside the stack.
Which solution will meet these requirements with the LEAST development effort?

A. Create an Amazon DynamoDB table as a resource in the CloudFormation stack to hold configuration data for the application Migrate the parameters that the application is modifying from Parameter Store to the DynamoDB table
B. Modify the CloudFormation stack policy to deny updates on Parameter Store parameters
C. Create an Amazon RDS DB instance as a resource in the CloudFormation stack. Create a table in the database for parameter configuration. Migrate the parameters that the application is modifying from Parameter Store to the configuration table
D. Modify the CloudFormation stack to set the deletion policy to Retain for the Parameter Store parameters.

정답：D

설명：
* Problem: CloudFormation updates reset Parameter Store parameters, disrupting application behavior.
* Deletion Policy: CloudFormation has a deletion policy that controls resource behavior when a stack is deleted or updated. The 'Retain' policy instructs CloudFormation to preserve a resource's current state.
* Least Development Effort: This solution involves a simple CloudFormation template modification, requiring minimal code changes.

질문 # 335
A developer is troubleshooting an application mat uses Amazon DynamoDB in the uswest-2 Region. The application is deployed to an Amazon EC2 instance. The application requires read-only permissions to a table that is named Cars The EC2 instance has an attached IAM role that contains the following IAM policy.

When the application tries to read from the Cars table, an Access Denied error occurs.
How can the developer resolve this error?

A. Modify the IAM policy resource to be "arn aws dynamo* us-west-2 account-id table/*"
B. Modify the IAM policy to include the dynamodb * action
C. Create a trust policy that specifies the EC2 service principal. Associate the role with the policy.
D. Create a trust relationship between the role and dynamodb Amazonas com.

정답：C

질문 # 336
A development team maintains a web application by using a single AWS CloudFormation template. The template defines web servers and an Amazon RDS database. The team uses the Cloud Formation template to deploy the Cloud Formation stack to different environments.
During a recent application deployment, a developer caused the primary development database to be dropped and recreated. The result of this incident was a loss of dat a. The team needs to avoid accidental database deletion in the future.
Which solutions will meet these requirements? (Choose two.)

A. Add a Cloud Formation DeletionPolicy attribute with the Retain value to the stack.
B. Add a CloudFormation Deletion Policy attribute with the Retain value to the database resource.
C. Update the CloudFormation stack policy to prevent updates to the database.
D. Modify the database to use a Multi-AZ deployment.
E. Create a CloudFormation stack set for the web application and database deployments.

정답：B,E

질문 # 337
A company receives food orders from multiple partners. The company has a microservices application that uses Amazon API Gateway APIs with AWS Lambda integration. Each partner sends orders by calling a customized API that is exposed through API Gateway. The API call invokes a shared Lambda function to process the orders.
Partners need to be notified after the Lambda function processes the orders. Each partner must receive updates for only the partner's own orders. The company wants to add new partners in the future with the fewest code changes possible.
Which solution will meet these requirements in the MOST scalable way?

A. Create an Amazon Simple Notification Service (Amazon SNS) topic. Configure the Lambda function to publish messages with specific attributes to the SNS topic. Subscribe each partner to the SNS topic. Apply the appropriate filter policy to the topic subscriptions.
B. Create a different Amazon Simple Notification Service (Amazon SNS) topic for each partner. Configure the Lambda function to publish messages for each partner to the partner's SNS topic.
C. Create a different Lambda function for each partner. Configure the Lambda function to notify each partner's service endpoint directly.
D. Create one Amazon Simple Notification Service (Amazon SNS) topic. Subscribe all partners to the SNS topic.

정답：A

설명：
Amazon Simple Notification Service (Amazon SNS) is a fully managed messaging service that enables pub/sub communication between distributed systems. The developer can create an SNS topic and configure the Lambda function to publish messages with specific attributes to the topic. The developer can subscribe each partner to the SNS topic and apply the appropriate filter policy to the topic subscriptions. This way, each partner will receive updates for only their own orders based on the message attributes. This solution will meet the requirements in the most scalable way and allow adding new partners in the future with minimal code changes.
