An IoT company sells hardware sensor modules that periodically send out temperature, humidity, pressure, and location data through the MQTT messaging protocol. The hardware sensor modules send this data to the company's on-premises MQTT brokers that run on Linux servers behind a load balancer. The hardware sensor modules have been hardcoded with public IP addresses to reach the brokers.
The company is growing and is acquiring customers across the world. The existing solution can no longer scale and is introducing additional latency because of the company's global presence. As a result, the company decides to migrate its entire infrastructure from on premises to the AWS Cloud. The company needs to migrate without reconfiguring the hardware sensor modules that are already deployed across the world. The solution also must minimize latency.
The company migrates the MQTT brokers to run on Amazon EC2 instances.
What should the company do next to meet these requirements?
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 finance company runs multiple applications on Amazon EC2 instances in two VPCs that are within a single AWS Region. The company uses one VPC for stock trading applications. The company uses the second VPC for financial applications. Both VPCs are connected to a transit gateway that is configured as a multicast router.
In the stock trading VPC, an EC2 instance that has an IP address of 10.128.10.2 sends trading data over a multicast network to the 239.10.10.10 IP address on UDP Port 5102. The company recently launched two new EC2 instances in the financial application VPC. The new EC2 instances need to receive the multicast stock trading data from the EC2 instance that is in the stock trading VPC.
Which combination of steps should the company take to meet this requirement? (Choose three.)
