Phy-Interface Configuration for Signaling and Media

B.

In the context of an Oracle Communications Session Border Controller (SBC) 7 implementation, a "phy-interface" configuration element is used to configure the physical interface settings on the SBC. This element is used for both signaling and/or media traffic.

Based on the options provided, the correct configuration step for a phy-interface element used for signaling and/or media is option C: "A phy-interface configuration element must be configured for each interface used."

This means that for each physical interface that will be used for signaling and/or media traffic, a separate phy-interface configuration element must be configured. The number of interfaces that will be used for signaling and/or media depends on the specific deployment scenario and network topology.

Option A is incorrect, as it suggests that phy-interface elements are only required for interfaces used for High Availability (HA) heartbeats, which is not the case.

Option B is also incorrect, as a reboot of the SBC is not required after configuring a phy-interface element for signaling and/or media.

Option D is incorrect, as it suggests that a single phy-interface element can be used for all signaling/media interfaces, which is not correct.

Option E is also incorrect, as the "operation-type" parameter is not specific to phy-interface elements and does not need to be set to "control" for signaling and/or media traffic.

In summary, the correct configuration step for a phy-interface element used for signaling and/or media is to configure a separate phy-interface element for each physical interface that will be used for signaling and/or media traffic.
