Question: What primary challenge in mobile networks led to the development of a data delivery enabler for vertical applications, as per SEAL architecture?
Option 1: Increasing complexity of network infrastructure
Option 2: Growing demand for application content transmission over mobile networks
Option 3: Need for enhanced voice call quality
Option 4: Requirement for reduced latency in signaling protocols
Explanation: The correct answer, Option 2, highlights the increasing demand for transmitting application content over mobile networks as the primary driver. This is directly related to the SEAL architecture's response to diverse data delivery requirements of vertical applications by offering a tailored data delivery enabler. This scenario reflects real-world implications where telecom networks must adapt to rising data transmission demands from various applications, making Option 2 the most relevant and accurate choice.
