the IP utility address and its virtual MAC address

B.

the virtual IP address and its hardcoded MAC address

C.

the IP utility address and its hardcoded MAC address

D.

Question 3

You are troubleshooting a SIP routing issue and you have access to the SIP call flow processed by the Session Border Controller.

Which two steps are valid for troubleshooting this type of issues? (Choose two.)

Options:

A.

It is necessary to locate the SIP session to troubleshoot and check if there is a 404 Routes Not Found SIP error message.

B.

It is recommended to look for 183 Session Progress SIP error messages that indicate routing issues.

C.

It is recommended to check the called number by looking at the Request-URI of the INVITE message and making sure it is a valid number to be routed.

D.

It is recommended to find the CANCEL method received by the Session Border Controller which typically identifies a SIP routing issue.

E.

It is necessary to find an initial INVITE received by the Session Border Controller which gets a 503 Service Unavailable SIP error message.

B.

Navigate to the session-agent configuration element and set the ip-address parameter to the IP subnet of your trusted User Agent (UA).

C.

Navigate to the realm-config configuration element and set the addr-prefix parameter to the IP subnet of your trusted User Agent (UA).

D.

Navigate to the sip-port configuration element and set the allow-anonymous parameter to agents-only.

the node that is configured as secondary

C.

the node that had the role of active last

D.

the node with the lowest wancom IP address

E.

the node with the highest round-robin score
