In the context of incident investigation, what kind of information is obtained by using monitoring tools like PRTG and Cacti that are capable of tracking SNMP data?

PRTG and Cacti are network monitoring tools that can provide data regarding bandwidth usage. Such bandwidth monitors can be useful in detecting abnormal bandwidth usage, exfiltration, and other relevant information that can aid in identifying and investigating incidents. If faced with a similar question in an exam, even if you are not acquainted with these tools, you can rely on your understanding of the purpose of Simple Network Management Protocol (SNMP) to determine which category is the most probable answer.
