Correct answer: vpn 0 interface interface-name tloc-extension interface-name.
Why this is the answer
The command vpn 0 interface interface-name tloc-extension interface-name is used to configure TLOC-extension, which provides local redundancy at a site by allowing a TLOC (Transport Locator) to be extended over a local interface. This means that if the primary TLOC fails, traffic can be rerouted through the extended interface, maintaining connectivity. The vpn 0 specifies the transport VPN, and interface interface-name identifies the local interface being extended. The second interface-name refers to the interface on the peer device that this TLOC is extending to. The other options are syntactically incorrect or do not represent the command for configuring TLOC-extension.
