A new application runs on Amazon EC2 instances and accesses data in an Amazon RDS database instance. When fully deployed in production, the application fails. The database can be queried from a console on a bastion host. When looking at the web server logs, the following error is repeated multiple times:

*** Error Establishing a Database Connection.

Which of the following may be causes of the connectivity problems? (Choose two.)

  • The security group for the database does not have the appropriate egress rule from the database to the web server.
  • The certificate used by the web server is not trusted by the RDS instance.
  • The security group for the database does not have the appropriate ingress rule from the web server to the database.
  • The database is still being created and is not available for connectivity.
