What should the SysOps Administrator analyze?

Explanations:

VPC Flow Logs provide detailed information about the traffic flowing in and out of the VPC. If there are network issues after a change, these logs can help identify if the application servers’ traffic is being blocked or misrouted, including security groups, NACLs, and routing issues.

Elastic Load Balancing logs track the behavior of load balancers, not database connectivity. Since the issue is with the connection to an Amazon RDS MySQL database, these logs would not be relevant.

Amazon CloudFront logs are related to content delivery and caching at edge locations, not database connections. Therefore, they are not helpful for diagnosing database connection issues.

Amazon RDS MySQL error logs primarily contain MySQL-specific database errors, but they would not provide information about network-level issues that occurred due to a network change, making them less useful for this scenario.
