A network administrator is configuring a WAN Edge router with two WAN connections and two TLOCs Which two attributes of TLOCs must be configured? (Choose two.)

The 'group-id' is an optional TLOC extension used for advanced policies, not a mandatory attribute for basic TLOC configuration.

The 'site-id' identifies the SD-WAN site, not a specific TLOC on a router.

The 'encapsulation' type, such as IPsec or GRE, defines how data plane tunnels are formed over the transport network, which is a required attribute for a TLOC. Each TLOC must specify an encapsulation.

The 'tloc-ip' is part of the TLOC identifier (the system IP of the router), but it is not a configurable attribute *within* the TLOC definition; rather, the TLOC is identified by the system-ip of the device it belongs to, along with its color and encapsulation.
