What is a valid configuration step when setting up a new VA to connect to ISC?

Using the registration token from ISC to connect the VA is indeed a valid configuration step. The registration token serves as a secure method to authenticate and establish a connection between the Virtual Appliance (VA) and the Identity Security Cloud (ISC). This token is specifically generated by ISC for the purpose of ensuring that the VA can seamlessly integrate with the ISC environment while maintaining the security and integrity of the connection.

The registration token helps streamline the setup process by providing an easy and secure means of confirming the identity and authorization of the VA within the ISC system. This method reduces the potential for human error that can occur with manual input or other methods of credential handling.

In contrast, skipping the use of the registration token may lead to authentication issues, as the VA requires a verified means of connecting to ISC. Similarly, using a self-generated token can lead to complications since tokens are meant to be issued and managed by the ISC itself to ensure they meet specific security standards and protocols. Manually inputting registration credentials could also introduce errors and is generally not recommended when there is a standardized method available. Hence, using the registration token is the most effective and secure approach for this initial configuration.
