Sample Questions

Question #217 / 529

A company hosts a web application using Amazon EC2 instances behind an Application Load Balancer (ALB) in one Availability Zone. The company wants to redesign the architecture to meet the following requirements:

- Inbound traffic must be scanned and blocked for common web-based attacks.
- All blocked requests must be stored in a third-party security monitoring system.
- The solution must be highly available.

Which solution satisfies these requirements?

A

Configure a Multi-AZ Auto Scaling group using the application's AMI. Deploy an ALB with the Auto Scaling group as the target. Use Amazon GuardDuty to detect threats and integrate it with AWS WAF. Enable logging for WAF using Amazon CloudWatch Logs. Use an AWS Lambda function to periodically export CloudWatch Logs to the third-party monitoring system.

B

Set up an ALB with EC2 instances as targets. Create a web ACL in AWS WAF and associate it with the ALB. Enable logging for WAF using Amazon S3. Configure an Amazon EventBridge rule to trigger an AWS Lambda function that forwards logs from S3 to the third-party monitoring system.

C

Deploy an ALB with EC2 instances in a target group. Create an Amazon Kinesis Data Firehose stream pointing to the third-party monitoring system. Configure AWS WAF with a web ACL, associate it with the ALB, and enable logging to the Kinesis stream. Use AWS Managed Rules for WAF but keep the EC2 instances in a single Availability Zone.

D

Configure a Multi-AZ Auto Scaling group using the application's AMI. Deploy an ALB with the Auto Scaling group as the target. Create a web ACL in AWS WAF and associate it with the ALB. Set up an Amazon Kinesis Data Firehose stream to deliver WAF logs to the third-party monitoring system. Enable logging in WAF with Kinesis as the destination and subscribe to AWS Managed Rules.

Question #47 / 529

A company is developing a serverless application hosted on AWS Lambda within a VPC. The application must communicate with an external API that mandates all requests originate from a single static public IPv4 address. The company needs to ensure the Lambda functions can securely access the API while adhering to this requirement.

Which solution will enable the application to meet the external provider's condition?

A

Deploy a NAT gateway in a public subnet. Assign an Elastic IP address to the NAT gateway. Update the VPC route tables to direct outbound traffic from the Lambda function's subnet to the NAT gateway.

B

Create an egress-only internet gateway. Attach an Elastic IP address to the gateway. Modify the Lambda function's security group to route traffic through the egress-only internet gateway.

C

Configure an internet gateway with an Elastic IP address. Update the Lambda function's elastic network interface to associate with the internet gateway's Elastic IP address.

D

Attach an internet gateway to the VPC. Assign an Elastic IP address to the internet gateway. Configure the main route table in the VPC to route all outbound traffic through the internet gateway.

Implement Amazon ElastiCache to cache frequently accessed query results.

B

Scale out the ECS service by increasing the number of tasks.

C

Provision additional RDS read replicas to distribute read traffic.
