What is a requirement for the nodes in a Dynatrace Managed multi-node setup regarding communication?

In a Dynatrace Managed multi-node setup, it is essential for each node to be able to communicate with Mission Control. This requirement is crucial because Mission Control is responsible for overseeing the entire environment, providing essential services such as configuration management, updates, and monitoring the health and status of each node. Maintaining open communication with Mission Control ensures that all nodes within the setup can coordinate effectively, receive necessary updates, and contribute to the overall performance and reliability of the monitoring system.

Other choices do not represent the core requirement for communication among nodes. For example, while time synchronization is important for maintaining accurate logs and reducing data discrepancies, the primary communication requirement centers around the connection to Mission Control. Similarly, while nodes may interact with external cloud services or databases, those interactions do not pertain to the fundamental communication necessity that ties the nodes together within the Dynatrace Managed framework.
