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.)
