7.1.5 Lesson Review Question 9 of 10 PTP can be deployed as a layer 3 protocol over IP. What is a limitation of this deployment? It increases the network bandwidth usage significantly. It cannot achieve the same accuracy as layer 2 implementations. Itrequires additional satellite synchronization. It is incompatible with most network adapters. I wont to review this question later. (Optionol)

The correct answer is: It cannot achieve the same accuracy as layer 2 implementations.<br /><br />When PTP (Precision Time Protocol) is deployed as a layer 3 protocol over IP, it cannot achieve the same accuracy as when it is implemented at layer 2. This is because layer 3 protocols, such as IP, introduce additional network latency and variability, which can negatively impact the accuracy of time measurements.
