Question 144

A financial service company has a two-tier consumer banking application. The frontend serves static web content. The backend consists of APIs. The company needs to migrate the frontendcomponent to AWS. The backend of the application will remain on premises. The company must protect the application from common web vulnerabilities and attacks.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Migrate the frontend to Amazon EC2 instances. Deploy an Application Load Balancer (ALB) in front of the instances. Use the instances to invoke the on-premises APIs. Associate AWS WAF rules with the instances.

Deploy the frontend as an Amazon CloudFront distribution that has multiple origins. Configure one origin to be an Amazon S3 bucket that serves the static web content. Configure a second origin to route traffic to the on-premises APIs based on the URL pattern. Associate AWS WAF rules with the distribution.

Migrate the frontend to Amazon EC2 instances. Deploy a Network Load Balancer (NLB) in front of the instances. Use the instances to invoke the on-premises APIs. Create an AWS Network Firewall instance. Route all traffic through the Network Firewall instance.

Deploy the frontend as a static website based on an Amazon S3 bucket. Use an Amazon API Gateway REST API and a set of Amazon EC2 instances to invoke the on-premises APIs. Associate AWS WAF rules with the REST API and the S3 bucket.

Question 145

A company hosts its order processing system on AWS. The architecture consists of a frontend and a backend. The frontend includes an Application Load Balancer (ALB) and Amazon EC2 instances in an Auto-Scaling group. The backend includes an EC2 instance and an Amazon RDS MySQL database.

To prevent incomplete or lost orders, the company wants to ensure that order states are always preserved. The company wants to ensure that every order will eventually be processed, even after an outage or pause. Every order must be processed exactly once.

Options:

Create an Auto Scaling group and an ALB for the backend. Create a read replica for the RDS database in a second Availability Zone. Update the backend RDS endpoint.

Create an Auto Scaling group and an ALB for the backend. Create an Amazon RDS proxy in front of the RDS database. Update the backend EC2 instance to use the Amazon RDS proxy endpoint.

Create an Auto Scaling group for the backend. Configure the backend EC2 instances to con-sume messages from an Amazon Simple Queue Service (Amazon SQS) FIFO queue. Configure a dead-letter queue (DLQ) for the SQS queue.

Create an AWS Lambda function to replace the backend EC2 instance. Subscribe the func-tion to an Amazon Simple Notification Service (Amazon SNS) topic. Configure the frontend to send orders to the SNS topic.

Question 146

An e-commerce company stores inventory, order, and user information in multiple Amazon Redshift clusters. The Redshift clusters must comply with the company's security policies. The company must receive notifications about any security configuration violations.

Which solution will meet these requirements?

Options:

Create an Amazon EventBridge rule that uses the Redshift clusters as the source. Create an AWS Lambda function to evaluate the Redshift cluster security configuration. Configure theLambda function to notify the company of any violations of the security policies. Add the Lambda function as a target of the EventBridge rule.

Create an AWS Lambda function to check the validity of the Redshift cluster security configurations. Create an Amazon EventBridge rule that invokes the Lambda function when Redshift clusters are created. Notify the company of any violations of security policies.

Set up Amazon Redshift Advisor in the company's AWS account to monitor cluster configurations. Configure Redshift Advisor to generate notifications for security items that the company must address.

Create an AWS Lambda function to check the Redshift clusters for any violation of the security configurations. Create an AWS Config custom rule to invoke the Lambda function when Redshift cluster security configurations are modified. Provide the compliance state of each Redshift cluster to AWS Config. Configure AWS Config to notify the company of any violations of the security policies.

Answer:

Explanation:

Comprehensive and Detailed Step-by-Step Explanation:

The company needsautomatic monitoringandnotificationsforsecurity violationsin Amazon Redshift clusters.

Option A:❌

Create an Amazon EventBridge rule that uses the Redshift clusters as the source. Create an AWS Lambda function to evaluate the Redshift cluster security configuration. Configure the Lambda function to notify the company of any violations of the security policies. Add the Lambda function as a target of the EventBridge rule.

EventBridgecan trigger actionsbased on events.

However, itdoes not track changesin Redshift security configurations.

Why not?AWS Configis bettersuited forcompliance monitoring.
