A company is running production workloads that use a Multi-AZ deployment of an Amazon RDS for MySQL db.m6g.xlarge (general purpose) standard DB instance. Users report that they are frequently encountering a "too many connections" error. A SysOps administrator observes that the number of connections on the database is high.
The SysOps administrator needs to resolve this issue while keeping code changes to a minimum.
Which solution will meet these requirements MOST cost-effectively?
A. Modify the RDS for MySQL DB instance to a larger instance size.
B. Modify the RDS for MySQL DB instance to Amazon DynamoDB.
C. Configure RDS Proxy. Modify the application configuration file to use the RDS Proxy endpoint.
D. Modify the RDS for MySQL DB instance to a memory optimized DB instance.
A company uses AWS CloudFormation to manage a stack of Amazon EC2 instances on AWS. A SysOps administrator needs to keep the instances and all of the instances' data, even if someone deletes the stack. Which solution will meet these requirements?
A. Set the DeletionPolicy attribute to Snapshot for the EC2 instance resource in the CloudFormation template.
B. Automate backups by using Amazon Data Lifecycle Manager (Amazon DLM).
C. Create a backup plan in AWS Backup.
D. Set the DeletionPolicy attribute to Retain for the EC2 instance resource in the CloudFormation template.
A company has an application that uses a scheduled AWS Lambda function to retrieve datasets from external sources over the internet. The function is not associated with a VPC. The company is modifying the application to store the information that the Lambda function retrieves on an Amazon RDS DB instance in a private subnet. The VPC has two public subnets and two private subnets.
A SysOps administrator must deploy a solution that allows the Lambda function to access the new database and continue to access the internet.
Which solution meets these requirements?
A. Create a new Lambda function with VPC access and an Elastic IP address. Attach the function to public subnets in two Availability Zones. Associate a security group with the Elastic IP address. Configure the security group outbound rules to allow Lambda to access the required resources.
B. Create a new Lambda function with VPC access and two public IP addresses. Attach the function to public subnets in the same Availability Zones that the database uses. Associate a security group with the function. Configure the security group inbound rules to allow Lambda to access the required resources.
C. Reconfigure the Lambda function for VPC access. Add NAT gateways to the public subnets in the VPAdd route table entries in the private subnets to route through the NAT gateways to the internet. Attach the function to the private subnets that support the database. Associate a security group with the function. Configure the security group outbound rules to allow Lambda to access the internet.
D. Reconfigure the Lambda function for VPC access. Attach the function to the private subnets. Add route table entries in the private subnets to route through the internet gateway to the internet. Associate a security group with the subnets. Configure the security group inbound rules to allow Lambda to access the required resources through the internet gateway.
A company's financial department needs to view the cost details of each project in an AWS account. A SysOps administrator must perform the initial configuration that is required to view cost for each project in Cost Explorer.
