Options:

Create an Amazon RDS Proxy. Assign the proxy to the DB instance.

Create a read replica for the DB instance Move the read traffic to the read replica.

Question 53

A solutions architect is designing a web application that will run on Amazon EC2 instances behind an Application Load Balancer (ALB). The company strictly requires that the application be resilient against malicious internet activity and attacks, and protect against new common vulnerabilities and exposures.

What should the solutions architect recommend?

Options:

Leverage Amazon CloudFront with the ALB endpoint as the origin.

Deploy an appropriate managed rule for AWS WAF and associate it with the ALB.

Subscribe to AWS Shield Advanced and ensure common vulnerabilities and exposures are blocked.

Configure network ACLs and security groups to allow only ports 80 and 443 to access the EC2 instances.

Enable the Amazon RDS Protection feature in Amazon GuardDuty for the member accounts of the organization.

Question 55

A company provides devices to users. When a device is registered, its ID is added to DynamoDB. A daily job activates devices using two Lambda functions:

• The Retrieve function lists unregistered device IDs.

• The Retrieve function then calls the Activate function in a loop to register each device.

The number of activations is increasing, and the company wants to avoid Lambda timeouts without modifying existing functions.

Which solution will scale appropriately?

Options:

Use EventBridge Scheduler to periodically invoke the Retrieve function.

Invoke the Activate function from DynamoDB Streams when a device ID is added.

Use Step Functions to call the Retrieve function and use a Map state to run the Activate function for each ID.

Move the Retrieve function to EC2 for longer processing time.
