Q40. An AWS workload in a VPC is running a legacy database on an Amazon EC2 instance. Data is stored on a 200GB Amazon EBS (gp2) volume. At peak load times, logs show excessive wait time.
What solution should be implemented to improve database performance using persistent storage?
A. Migrate the data on the Amazon EBS volume to an SSD-backed volume
B. Change the EC2 instance type to one with EC2 instance store volumes
C. Migrate the data on the EBS volume to provisioned IOPS SSD (io1).
D. Change the EC2 instance type to one with burstable performance.
Q39. A Solutions Architect is designing a new application that needs to access data in a different AWS account located within the same region. The data must not be accessed over the Internet.
Which solution will meet these requirements with the LOWEST cost?
A. Add rules to the security groups in each account.
B. Establish a VPC Peering connection between accounts.
C. Configure Direct Connect in each account.
D. Add a NAT Gateway to the data account.
Q38. A Solutions Architect is designing a VPC. Instances in a private subnet must be able to establish IPv6 traffic to the Internet. The design must scale automatically and not incur any additional cost.
This can be accomplished with:
A. an egress-only internet gateway
B. a NAT gateway
C. a custom NAT instance
D. a VPC endpoint
Q37. An application is running on an Amazon EC2 instance in a private subnet. The application needs to read and write data onto Amazon Kinesis Data Streams, and corporate policy requires that this traffic should not go to the internet.
How can these requirements be met?
A. Configure a NAT gateway in a public subnet and route all traffic to Amazon Kinesis through the NAT gateway.
B. Configure a gateway VPC endpoint for Kinesis and route all traffic to Kinesis through the gateway VPC endpoint.
C. Configure an interface VPC endpoint for Kinesis and route all traffic to Kinesis through the interface VPC endpoint
D. Configure an AWS Direct Connect private virtual interface for Kinesis and route all traffic to Kinesis through the virtual interface.
Q36. A Lambda function must execute a query against an Amazon RDS database in a private subnet. Which steps are required to allow the Lambda function to access the Amazon RDS database? (Choose two.)
A. Create a VPC Endpoint for Amazon RDS.
B. Create the Lambda function within the Amazon RDS VPC.
B. Change the ingress rules of Lambda security group, allowing the Amazon RDS security group.
D. Change the ingress rules of the Amazon RDS security group, allowing the Lambda security group.
E. Add an Internet Gateway (IGW) to the VPC, route the private subnet to the IGW.
Q35. A Solutions Architect is designing an Amazon VPC. Applications in the VPC must have private connectivity to Amazon DynamoDB in the same AWS Region.
The design should route DynamoDB traffic through:
A. VPC peering connection.
B. NAT gateway
C. VPC endpoint
D. AWS Direct Connect
Q34. A Solutions Architect is designing network architecture for an application that has compliance requirements. The application will be hosted on Amazon EC2 instances in a private subnet and will be using Amazon S3 for storing data. The compliance requirements mandate that the data cannot traverse the public Internet.
What is the MOST secure way to satisfy this requirement?
A. Use a NAT Instance.
B. Use a NAT Gateway.
C. Use a VPC endpoint.
D. Use a Virtual Private Gateway.
Q33. A Solutions Architect is designing an application on AWS that will connect to the on-premise data center through a VPN connection. The solution must be able to log network traffic over the VPN.
Which service logs this network traffic?
A. AWS CloudTrail logs
B. Amazon VPC flow logs
C. Amazon S3 bucket logs
D. Amazon CloudWatch Logs
Q32. A legacy application running in premises requires a Solutions Architect to be able to open a firewall to allow access to several Amazon S3 buckets. The Architect has a VPN connection to AWS in place.
How should the Architect meet this requirement?
A. Create an IAM role that allows access from the corporate network to Amazon S3.
B. Configure a proxy on Amazon EC2 and use an Amazon S3 VPC endpoint.
C. Use Amazon API Gateway to do IP whitelisting.
D. Configure IP whitelisting on the customer’s gateway.
Q31. An external service to ping the VPN endpoint from outside the VPC.
AWS CloudTrail to monitor the endpoint.
the CloudWatch TunnelState Metric.
an AWS Lambda function that parses the VPN connection logs.
A. an external service to ping the VPN endpoint from outside the VPC.
B. AWS CloudTrail to monitor the endpoint.
C. the CloudWatch TunnelState Metric.
D. an AWS Lambda function that parses the VPN connection logs.
