Sample Questions

Question #90 / 529

A company has VPC flow logs enabled for its NAT gateway. The company is observing Action = ACCEPT for inbound traffic originating from public IP address 203.0.100.5 destined for a private Amazon EC2 instance. A solutions architect needs to determine if this traffic represents unsolicited inbound connections from the internet. The first two octets of the VPC CIDR block are 192.168. Which set of steps should the solutions architect take to meet these requirements?

A

Open the AWS CloudTrail console. Select the log group containing the NAT gateway's elastic network interface and the private instance's elastic network interface. Run a query to filter with the destination address set as \"like 192.168\" and the source address set as \"like 203.0.100.5\". Run the stats command to filter the sum of bytes transferred by the source and destination addresses.

B

Open the Amazon CloudWatch console. Select the log group containing the NAT gateway's elastic network interface and the private instance's elastic network interface. Run a query to filter with the destination address set as \"like 192.168\" and the source address set as \"like 203.0.100.5\". Run the stats command to filter the sum of bytes transferred by the source and destination addresses.

C

Open the AWS CloudTrail console. Select the log group containing the NAT gateway's elastic network interface and the private instance's elastic network interface. Run a query to filter with the destination address set as \"like 203.0.100.5\" and the source address set as \"like 192.168\". Run the stats command to filter the sum of bytes transferred by the source and destination addresses.

D

Open the Amazon CloudWatch console. Select the log group containing the NAT gateway's elastic network interface and the private instance's elastic network interface. Run a query to filter with the destination address set as \"like 203.0.100.5\" and the source address set as \"like 192.168\". Run the stats command to filter the sum of bytes transferred by the source and destination addresses.

Question #421 / 529

A company operates a web application leveraging Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. A sudden spike in user traffic has led to increased latency.

Application logs show that errors coincide with DynamoDB operations.

What should the solutions architect recommend to enhance performance and reduce errors as traffic grows?

C

Adjust API Gateway's rate limiting settings.

D

Modify the DynamoDB table's primary key structure.

A

Raise the Lambda function's concurrency limit.
