An engineer must configure a cisco ISR 4000 as an MGCP gateway to download its MGCP- specific configuration from cisco UCM. Which Cisco IOS configuration snippet accomplishes this task?
The correct answer is D. ISR4K(config)# ip tftp source-interface GigabitEthernet 0/0/1. To enable a Cisco ISR 4000 MGCP gateway to download its configuration from Cisco UCM, the ip tftp source-interface command ensures TFTP requests originate from a specific interface for proper communication and routing.

Why each option
To enable a Cisco ISR 4000 MGCP gateway to download its configuration from Cisco UCM, the `ip tftp source-interface` command ensures TFTP requests originate from a specific interface for proper communication and routing.
All choices are identical. Assuming this would represent an incorrect option in a real exam, it would be wrong if it failed to correctly configure the TFTP source interface for MGCP configuration downloads.

In an MGCP gateway setup, Cisco UCM provides configuration files via TFTP. The `ip tftp source-interface GigabitEthernet 0/0/1` command ensures that any TFTP requests made by the ISR 4000, including those for downloading its MGCP-specific configuration from Cisco UCM, will originate from the specified interface. This is important for proper routing, firewall traversal, and consistent identification by the UCM, particularly when the gateway has multiple active interfaces.
