Which option is a fate-sharing characteristic in regards to network design?

Fate-sharing describes a situation where two or more services or components are tied together such that failure in one leads to failure in others. In resilient design, the goal is often to eliminate fate-sharing by decoupling dependencies.

A: A single point of failure (like a shared power supply or converged service path) that brings down multiple components exemplifies fate-sharing.

B is incorrect because fate-sharing is a risk, not a protective measure.

C and D refer to device behavior (stateful inspection, transport layer behavior) rather than architectural dependency.
