Explanation

An External Virtual Router requires a real, dedicated physical interface on the device because it must connect to an actual external network segment - you need a tangible port to plug a cable into for upstream connectivity. This is the fundamental distinction between "external" (facing outside the device, requiring a physical handoff) and internally managed logical constructs.

Why the distractors are wrong:

• A. Virtual - Virtual interfaces are logical constructs (loopbacks, VLANs, tunnels) with no physical port; the External Virtual Router needs a concrete hardware attachment point.
• B. Symbolic - Not a recognized interface classification in networking; likely included as a plausible-sounding distractor.
• C. Synchronization - Sync interfaces serve a specific purpose (e.g., HA state replication between peers) and are not associated with routing external traffic.
• D. Warp - Not a standard networking interface type; another distractor with no technical basis here.

Memory tip: Anchor on the word external - anything that faces the outside world needs a real, physical handoff point you can trace with your finger on the hardware. If it's physical, it's real; if it's real, it's external. "External = Physical" is the pairing to burn in.
