The purpose of a protocol analyzer is:  2 pointsOption 1 to determine what services might be running on a remote device.Option 2 It allows you to view traffic patterns.Option 3 scan an individual IP address, and report back whatever it finds outOption 4 to see if access points are susceptible to deauthentication attacks.

The purpose of a protocol analyzer is primarily Option 2: It allows you to view traffic patterns. A protocol analyzer, also known as a packet analyzer, is a tool used to capture and analyze the traffic on a network. It helps in diagnosing network problems, understanding network usage patterns, and identifying potential security breaches.

While the other options may be functions of specific types of network tools, they are not the primary purpose of a protocol analyzer. For instance, Option 1 and Option 3 are more related to network scanning tools, which identify services running on a device or scan IP addresses. Option 4 is more related to penetration testing tools, which test the vulnerability of access points.

The purpose of a protocol analyzer is primarily Option 2: It allows you to view traffic patterns. A protocol analyzer, also known as a packet analyzer, is a tool used to capture and analyze network traffic. This tool helps network administrators to diagnose and solve network problems, analyze network performance, and detect network intrusion attempts.

However, it's worth noting that a protocol analyzer can also be used for some of the purposes mentioned in the other options, depending on its specific features and the skills of the user. For example, it can sometimes help to determine what services might be running on a remote device (Option 1), or to scan an individual IP address and report back whatever it finds out (Option 3).

Option 4, to see if access points are susceptible to deauthentication attacks, is more specific to wireless network analyzers and not a primary function of a general protocol analyzer.
