正解:D
Asniffer(also known as a packet analyzer) is a tool that captures and inspects data packets traveling across the network. In this case, using a sniffer would help identify suspicious or malicious redirection of traffic, possibly caused by a man-in-the-middle attack, DNS hijacking, or malware. * Sniffer (Answer D):This tool will allow the senior administrator to inspect the network traffic and identify if and how requests to the anti-malware website are being intercepted or redirected. * Data loss prevention (Option A):DLP tools focus on preventing data leakage rather than analyzing traffic redirection. * File integrity monitor (Option B):This checks for unauthorized changes to files, which may not directly address network traffic redirection. * Port scanner (Option C):A port scanner would only identify open ports on devices, which is unrelated to the redirection issue.
