The best answers are A and D , but be careful: A is directly verified by the guide; D is the only remaining statement that can be true in policy context, but it is weaker than A.

The FortiEDR 7.0.0 Administration Guide states that the Communication Control tab identifies communicating applications detected in the organization. More specifically, the Applications page lists “all communicating applications detected in your organization that have ever attempted to communicate.” Therefore, if software exists on a user’s computer but does not appear in the Communication Control application list, the most direct explanation is that it has not attempted external communication .

The guide also explains that FortiEDR Communication Control reduces the scope of administration because Security/IT only needs to handle applications that communicate externally. It also states that non-authorized applications can still execute, and only their outgoing communication is prevented. This confirms that the Communication Control application list is not a full software inventory; it is a list of applications that have communicated or attempted communication.

Option B is not correct. If an application were blocked due to FortiEDR security-policy enforcement after a connection attempt, FortiEDR would generate security-event visibility in the Incidents workflow, not simply hide the application from Communication Control. FortiEDR Collectors send communication-related data for Communication Control, and security events are sent for enforcement/monitoring purposes.

Option C is also wrong. Reputation score affects policy decisions and application risk evaluation, but it does not cause an application to be ignored or excluded from the application list. The guide says each application in the Applications page shows a reputation indicator, which proves reputation is displayed for listed applications rather than used to hide them.

For option D , if the application has never attempted communication, Communication Control has no observed communication event to list. In exam logic, this can be interpreted as the application is not currently being denied by Communication Control policies. However, the stronger technical truth is this: Communication Control does not list installed software; it lists applications that have attempted to communicate.
