What requirement must be checked before connecting Dynatrace Managed environments with the mobile app?

Connecting Dynatrace Managed environments with the mobile app necessitates ensuring that the firewall settings are properly configured to permit incoming connections to the Cluster ActiveGate domain. This requirement is critical because the mobile app communicates with the Dynatrace Managed environment through this domain. If the firewall blocks these connections, the mobile app will not be able to retrieve data or function correctly, interrupting the monitoring and performance management process that Dynatrace offers.

Ensuring that the firewall allows these incoming connections is a key step in maintaining seamless integration and functionality, which reflects the necessity of a well-structured network configuration for effective monitoring solutions.

Other options involve conditions that either misrepresent the requirements or introduce security vulnerabilities, such as ignoring SSL certificates or relying on default settings which might not be sufficient for secure and effective operations.
