Which of the following best describes PfR?
The correct answer is A. PfR enables adaptive routing adjustments. Performance Routing (PfR) is Cisco's technology that monitors real-time network performance metrics-such as delay, jitter, packet loss, and MOS scores-and dynamically adjusts routing decisions based on those metrics. This makes 'adaptive routing adjustments' the most accurate…

Explanation
Performance Routing (PfR) is Cisco's technology that monitors real-time network performance metrics-such as delay, jitter, packet loss, and MOS scores-and dynamically adjusts routing decisions based on those metrics. This makes 'adaptive routing adjustments' the most accurate description. Option B is incorrect because PfR uses dynamic, real-time parameters-not a static set. Option C is incorrect because there are actually three versions of PfR (OER/PfRv1, PfRv2, and PfRv3). Option D is incorrect because PfR uses a Master Controller (MC), not a designated router, to make path decisions.
