Suggested answer: B

Explanation:

When analyzing Wireshark traffic for potential attacks, an engineer should look for patterns that indicate abnormal behavior, such as:

Excessive Requests: A high number of requests over a short period could suggest an attempt to overwhelm the server, known as an HTTP flood.

Status Codes: Repeated403 Forbiddenresponses may indicate that the server is rejecting requests due to a security rule being triggered.

Request Types: A mix ofGETandPOSTrequests could be used in various attack scenarios, including bandwidth flooding or cache bypassing.
