When do port-hour charges begin after creating an AWS Direct Connect connection?

1. Immediately after setup

2. When the connection is established

3. When the connection becomes available for the first time if it's less than 90 days

4. After 30 days of usage

The correct answer is: When the connection becomes available for the first time if it's less than 90 days

Port-hour charges for an AWS Direct Connect connection start when the connection becomes available for the first time, but this only applies if it's done within the first 90 days of the connection being created. This means that even if the connection is created, charges will not accrue until it is available for use. These charges reflect the time the port is ready for utilization, which is essential for billing purposes. This understanding is key because it aligns with AWS's billing model, which is structured around resources that are provisioned and ready for use. If the connection is established but is not yet available, AWS will not charge for port-hours until the connection is fully operational. However, this also highlights the importance of activation within the first 90 days, after which different billing practices might apply or cause additional charges. Hence, being proactive about setting up and utilizing the Direct Connect service can optimize costs and resource management.
