SIP trunks can be configured with up to 16 destination IP addresses, 16 fully qualified domain names, or a single DNS SRV entry.

In Cisco Unified Communications Manager (CUCM), a Session Initiation Protocol (SIP) trunk is a means of connecting two entities that use SIP to communicate with each other. SIP trunks are used to provide connectivity between CUCM and other SIP-based systems, such as IP telephony gateways, voice-over-IP (VoIP) service providers, and unified messaging systems.
When configuring a SIP trunk on CUCM 9.1, you can specify one or more destination addresses for the trunk. The destination address can be an IP address or a domain name, and can include a port number. In addition, you can specify an SRV record as the destination address for the trunk.
An SRV record is a DNS record that specifies the hostname and port number of a server that provides a specific service. When a SIP client needs to communicate with a SIP server, it can use an SRV record to locate the server and determine the port number to use.
In the case of a SIP trunk on CUCM 9.1, specifying an SRV record as the destination address allows CUCM to use DNS to dynamically locate the SIP server(s) associated with the SRV record. This can provide greater flexibility and redundancy in the event that the SIP server(s) change or fail.
The question asks how many destinations can be configured for a SIP trunk on CUCM 9.1 when the destination address is an SRV. The answer is A. 1. This means that only one SRV record can be specified as the destination address for a SIP trunk on CUCM 9.1.
In summary, when configuring a SIP trunk on CUCM 9.1, you can specify one or more destination addresses, including an SRV record. However, only one SRV record can be specified as the destination address for a SIP trunk on CUCM 9.1.
