NC Authorization Hosts rely on keyword handshakes to allow communication every how many minutes?

The correct answer is based on the mechanism by which NC Authorization Hosts utilize keyword handshakes to manage secure communications. Specifically, these hosts perform handshakes every 5 minutes to validate authorized connections and maintain secure communication channels. This frequent re-evaluation allows for a dynamic approach to authorization, ensuring that any changes in the status of devices or users can be reflected quickly, thereby enhancing security.

Frequent handshakes help to mitigate risks associated with stale authorizations and ensure that only verified entities are able to communicate within a network. This time frame strikes a balance between security and performance, minimizing potential vulnerabilities without causing unnecessary overhead on system resources.
