A company has a VPC that includes application workloads that run on Amazon EC2 instances in a single AWS Region. The company wants to use AWS Local Zones to deploy an extension of the application workloads that run in the Region. The extended workloads in the Local Zone need to communicate bidirectionally with the workloads in the VPC in the Region.

An education agency is preparing for its annual competition between schools. In the competition, students at schools from around the country solve math problems, complete puzzles, and write essays.
The IP addressing plan of all the schools is well-known and is administered centrally. The competition is hosted in the AWS Cloud and is not publicly available. All competition traffic must be encrypted in transit. Only authorized endpoints can access the competition. All the schools have firewall policies that block ICMP traffic.
A network engineer builds a solution in which all the schools access the competition through AWS Site-to-Site VPN connections. The network engineer uses BGP as the routing protocol. The network engineer must implement a solution that notifies schools when they lose connectivity and need to take action on their premises to address the issue.
Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)
A company has a transit gateway in a single AWS account. The company sends flow logs for the transit gateway to an Amazon CloudWatch Logs log group.
The company created an AWS Lambda function to analyze the logs. The Lambda function sends a notification to an Amazon Simple Notification Service (Amazon SNS) topic when a VPC generates traffic that is dropped by the transit gateway. Each notification contains the account ID. VPC ID, and total amount of dropped packets.
The company wants to subscribe a new Lambda function to the SNS topic. The new Lambda function must automatically prevent the traffic that is identified in each notification from leaving a VPC by applying a network ACL to the transit gateway attachment subnets in the VPC that generates the traffic.
