Configure Maximum Session Duration

C.

To configure the maximum duration in seconds of any session in the Session Border Controller (SBC), you would need to navigate to the configuration element that controls session management. In this case, the relevant configuration elements are "media-manager" and "sip-config."

The correct answer is option D: Navigate to the sip-config configuration element and configure the flow-time-limit parameter.

The "flow-time-limit" parameter in the "sip-config" configuration element specifies the maximum duration, in seconds, for any SIP session. When the session exceeds the specified duration, the SBC terminates the session. This is a useful feature to prevent sessions from hogging system resources and potentially causing denial-of-service (DoS) attacks.

To configure the flow-time-limit parameter, you would follow these steps:

1. Log in to the SBC's web management interface.
2. Navigate to the "Configuration" menu and select "Profiles" from the dropdown menu.
3. Select the profile that you want to modify, and click the "Edit" button.
4. In the "Profile Configuration" window, select the "SIP" tab.
5. In the "SIP" tab, scroll down to the "SIP Signaling" section.
6. Find the "flow-time-limit" parameter and enter the maximum duration, in seconds, that you want to allow for any session.
7. Click the "Save" button to save the changes.

Note that the other answer options are incorrect:

A. The "max-signaling-bandwidth" parameter in the "media-manager" configuration element controls the maximum bandwidth, in bits per second (bps), that the SBC can use for signaling traffic. This parameter does not relate to session duration. B. The "flow-time-limit" parameter is not located in the "media-manager" configuration element. This answer option is incorrect. C. The "operation-mode" parameter in the "sip-config" configuration element controls how the SBC processes SIP messages. This parameter does not relate to session duration. E. The "latching" parameter in the "media-manager" configuration element controls how the SBC handles media streams. This parameter does not relate to session duration.
