Can you deploy a Message Relay without an Update Cache?

To deploy a Message Relay, it is essential to have an Update Cache. The Update Cache plays a critical role in storing updates and other data that the Message Relay uses to provide services such as distribution of updates to endpoints. By relying on the Update Cache, the Message Relay can reduce bandwidth usage and improve the efficiency of update delivery across the network.

Without an Update Cache, the Message Relay would not be able to fulfill its purpose effectively since it would lack the stored updates necessary for its operation. Hence, it cannot function independently without this component. The integration of the Message Relay with an Update Cache ensures seamless communication and data flow, which is fundamental to maintaining security and system updates within the organization.

The other options suggest scenarios where a Message Relay might operate without an Update Cache, but such configurations would typically not align with optimal functioning and best practices established in the industry.
