How is TLOC defined?
The correct answer is D. It is a unique collection of GRE or IPsec encapsulations, link color, and system IP address. A TLOC (Transport Locator) in Cisco SD-WAN is uniquely defined by the combination of the WAN Edge router's system IP address, the transport link's color, and the encapsulation type.

Why each option
A TLOC (Transport Locator) in Cisco SD-WAN is uniquely defined by the combination of the WAN Edge router's system IP address, the transport link's color, and the encapsulation type.
A site in SD-WAN is typically identified by a site-ID, not a TLOC, which represents a specific transport interface on a WAN Edge.
A TLOC defines a specific transport connection for a WAN Edge, not an entire Cisco SD-WAN overlay in a multitenant vSmart deployment.
TLOCs are fundamental identifiers for transport endpoints, not a group of QoS policies, although QoS policies can be applied to traffic flowing through a TLOC.
A TLOC (Transport Locator) is defined by a unique combination of the WAN Edge router's system IP address, the link's color (which identifies the transport network), and the tunnel encapsulation type (IPsec or GRE).
