What is a characteristic of a Layer 2 loop?
- Broadcast frames are forwarded back to the sending switch.
- The Time-to-Live attribute of a frame is set to infinity.
- Routers continually forward packets to other routers.
- A switch is continually forwarding the same unicast frame.
Explanation: A Layer 2 loop occurs when broadcast frames are forwarded back to the sending switch via a backup link. Layer 2 frames do not have a Time-to-Live (TTL) attribute. Routers forward packets at Layer 3 (the network layer) not Layer 2.
