Regarding Discover, which of the following is a con for the Level 2 Discovery Method?

The Level 2 Discovery Method in Tanium is typically beneficial for its ability to gather information from endpoints, but it also comes with certain drawbacks. The correct con associated with this method is that it generates ICMP traffic.

When the Level 2 Discovery Method sends ICMP (Internet Control Message Protocol) packets, it can lead to an increased volume of network traffic, which might not be desirable in all environments. This can be a concern for network administrators, especially in environments where bandwidth is limited, or where ICMP traffic is monitored closely.

Since it generates this specific type of traffic, it could impact network performance or be flagged by security devices, which may prioritize or limit certain types of network traffic. The volume of ICMP traffic might also lead to monitoring solutions generating alerts or false positives, complicating incident response efforts.

While the other potential concerns listed may also be valid under different circumstances, generating ICMP traffic is a notable characteristic that can serve as a clear con of using the Level 2 Discovery Method. This illustrates the trade-offs in network discovery techniques, emphasizing the need for careful consideration of the network environment and security policies when implementing such methods.
