Your company has set up an AWS Direct Connect connection with the help of an AWS Partner. The customer gateway is in an on-premises data center. Your operations department needs to be informed whenever the Direct Connect connection is down. How can you achieve this?

Answer options:

A.Use the AWS Direct Connect tunnel logging facility to check for any failures.
B.Use Cloudwatch metrics to check for the state of the connection.
C.Use Cloudwatch logs to check for the state of the connection.
D.Use AWS Service Health Dashboard to view the status.

Answer – B
The AWS Direct Connect service now has a metric available in Cloudwatch called Connection State. You can design an alarm whenever the connection state is DOWN.
Options A and C are invalid because no such entries are available for Direct Connect.
Option D, the AWS Service Health Dashboard, would give the health of AWS Direct Connect for a particular region and not from a particular vendor and is, therefore, incorrect.
