By using an ActiveGate, firewall settings can be simplified because _____?

The correct answer emphasizes the role of the ActiveGate in streamlining communication between monitored environments and the Dynatrace Server. When using an ActiveGate, only the machine or host where the ActiveGate is installed needs to maintain a connection to the Dynatrace Server. This simplifies firewall settings because only this single connection needs to be configured and allowed through firewalls, rather than requiring individual configurations for each agent or monitored service across the network.

This setup reduces the complexity and potential number of rules that need to be created on the firewall, which is particularly beneficial in environments with many agents or services that require monitoring. By centralizing the connection point, it also helps in managing network security, as administrators can focus on securing a single entry point rather than multiple potential ingress points.

In contrast, options that suggest filtering multiple gateways or independence of data handling do not directly relate to the simplification of firewall settings. Similarly, suggestions of increased configuration complexity with multiple connections contradict the core advantage provided by using an ActiveGate. The essence lies in how the ActiveGate serves as a single, manageable connection to streamline networking requirements, enhancing both security and ease of configuration.
