When configuring a SIP route pattern, which two provide the basis for routing? (Choose two.)
The correct answer is B. domain name D. IP address. SIP route patterns in CUCM route calls based on the domain name or IP address found in the SIP URI, reflecting how SIP addressing works at the network layer.

Why each option
SIP route patterns in CUCM route calls based on the domain name or IP address found in the SIP URI, reflecting how SIP addressing works at the network layer.
E.164 numbers are used as the basis for traditional dial plan route patterns for PSTN routing, not for SIP route patterns which operate on URI host identifiers.
A SIP URI has the format sip:user@host, where the host portion can be a domain name (e.g., sip:[email protected]), making domain name a valid routing basis for SIP route patterns in CUCM.
MAC addresses are Layer 2 hardware identifiers used for device registration and discovery in CUCM, not for SIP call routing or route patterns.
The host portion of a SIP URI can also be an IP address (e.g., sip:[email protected]), so CUCM SIP route patterns use IP addresses to forward calls to the correct SIP trunk or destination server.
Directory numbers are internal CUCM endpoint identifiers used to reach registered phones, not network-layer identifiers that form the basis of SIP route patterns.
