Emergency Nurse Practitioner (ENP) Practice Test 2025 - Free ENP Practice Questions and Study Guide

LTE, or Long Term Evolution, is a high-speed wireless communication technology. It is commonly used in the telecommunications industry for data communication over cellular networks. COBRA, or Compact Baseband Radio, is a crucial component of LTE networks. It is responsible for managing the transmission and reception of data between the user devices and the network. This is done by allocating bandwidth and managing the quality of service. Option A, Emergency radio access network, may seem like a plausible answer, but it is incorrect because COBRA is not specifically designed for emergency purposes. It is a critical part of the overall LTE network structure. Similarly, option B, Layered transport systems, may sound like a valid answer, but it is incorrect because LTE networks utilize flat network architecture, where the transport of data is done primarily through IP networks. Option D, Distinct corn layers, is a completely unrelated and nonsensical answer. Hence, option C, Public safety devices, is the correct answer as it directly relates to the function and purpose of COBRA in LTE networks.
