Attach the private network's subnet to the router and set the router's gateway to the external network.

Add a security group rule to allow all traffic between the private and external networks.

Create a new subnet on the external network and attach it to the router.

Assign a floating IP to the instance from the external network pool.

What is the purpose of an SSH key pair in OpenStack?

To authenticate to instances via SSH without using a password

To encrypt data stored in volumes

To sign API requests to OpenStack services

To authenticate users to the Horizon dashboard

What is the purpose of the 'Create Image' function in Horizon?

To delete an existing image from the cloud
