Q13 Single choice

A company has set up hybrid connectivity between an on-premises data center and AWS by using AWS Site-to-Site VPN. The company is migrating a workload to AWS.

The company sets up a VPC that has two public subnets and two private subnets. The company wants to monitor the total packet loss and round-trip-time (RTT) between the data center and AWS.

Which solution will meet these requirements with the LEAST operational overhead?

A
Use Amazon CloudWatch Network Monitor to set up Internet Control Message Protocol (ICMP) probe monitoring from each subnet to the on-premises destination.
B
Create an Amazon EC2 instance in each subnet. Create a scheduled job to send Internet Control Message Protocol (ICMP) packets to the on-premises destination.
C
Create an AWS Lambda function in each subnet. Write a script to perform Internet Control Message Protocol (ICMP) connectivity checks.
D
Create an AWS Batch job in each subnet. Write a script to perform Internet Control Message Protocol (ICMP) connectivity checks.
