• C.To set up a voice session, SIP relies on protocols such as SDP and RTP.
• D.A SIP transaction occurs between a client and a server.
• E.SIP defines native methods for negotiating media streams.

You are adding peers to a Policy-Based Realm Bridging (PBRB) configuration.
Which two configuration steps, among others, are required? (Choose two.)

• A.Navigate to the media-manager configuration branch and configure the realm-config configuration element.
• B.Navigate to the session-router configuration branch and configure the local-policy configuration element.
• C.Navigate to the session-router configuration branch and configure the sip-nat configuration element.
• D.Navigate to the session-router configuration branch and configure the sipd-address configuration element.
• E.Navigate to the media-manager configuration branch and configure the access-control configuration element.

Whichtwo statements are true about SIP response code handling on the Session Border
Controller? (Choose two.)

• A.By default, the Session Border Controller will recurse on the 6xx messages.
• B.The Session Border Controller cannot originate 3xx class redirect responses.
• C.The Session Border Controller will originate a 503 when there are no steering pool ports available.
• D.The Session Border Controller can transmit a different SIP response code than it received.
• E.The Session Border Controller will originate a 403 response when bandwidth allocated to a realm has been exhausted.

You are logged in to the Session Border Controller a superuser. You want to remove other user from the system.
How do you accomplish this?

• A.from the user mode, by executing the kill <index number> command
• B.from the superuser mode, by executing the remove user <username> command
• C.from the superuser mode, by executing the remove user <index number> command
• D.from the superuser mode, by executing the kill <index number> command
• E.from the user mode, by executing the remove user <index number> command

The Session Border Controller is not routing calls to a specific SIP endpoint from the backbone realm to the access realm in an Access-Backbone architecture.
How can you troubleshoot this routing issue?

• A.by running the notify berpd force command
• B.by checking the sip-manipulation configuration element used for routing from the backbone realm to the access realm
• C.by checking the registration-cache configuration element used for routing from the access realm to the backbone realm
• D.by checking the local-policy configuration element used for routing from the access realm to the backbone realm
• E.by running the show sipd endpoint-ip <phone number> command
