Final answer:
JBL is likely engaging in packet capture and traffic analysis, which entails monitoring and analyzing data traffic over a network to identify and address various network-related issues.
Step-by-step explanation:
JBL is likely performing packet capture and traffic analysis among the options provided.
Packet capture and traffic analysis involve monitoring network traffic to inspect the data being sent and received over the network. This process is crucial for network troubleshooting, security analysis, and optimizing network performance. Tools for packet capture, such as Wireshark, enable administrators to intercept and log traffic that passes over a network or part of a network. With traffic analysis, the captured data can be meticulously analyzed for various purposes, such as identifying network issues, unauthorized access, or inefficient data handling.
While packet capture is a passive activity and generally legal when performed on networks managed by the individual or organization, it's important to note that capturing packets on a network that you do not own may be illegal and raise ethical concerns. This task differs from network configuration, data encryption, and firewall management, which involve setting network parameters, securing data transmission, and controlling access to the network, respectively. Each of these activities plays a distinct role in maintaining a secure and efficient network infrastructure.
