Which TCP must be opened in the firewall between Services server and Messaging server?

Explanation

Port 15097 is the designated inter-server communication port used by the Messaging server to receive connections from the Services server in this architecture. Without this port open in the firewall, the Services server cannot establish the required TCP connection to the Messaging server, breaking the communication channel entirely.

Why the distractors are wrong:

• A (587): This is the SMTP mail submission port, used by email clients to hand off messages to a mail relay - unrelated to inter-server service messaging.
• B (9001): This port is associated with tools like the Supervisor process manager or Tor - not the Services-to-Messaging server communication path in this context.
• D (47500): This is the default discovery/communication port for Apache Ignite cluster nodes - a different technology and role entirely.

Memory tip: The number 15097 doesn't map to a well-known "universal" standard, so treat it as product-specific knowledge - anchor it by remembering that it sits between the common range (< 1024 for well-known ports) and the ephemeral range (> 49152), marking it as a deliberate application-assigned port. If your exam covers a specific platform (e.g., Genesys, Cisco, or IBM), check that platform's official port reference sheet and highlight 15097 as the Services↔Messaging firewall rule.
