To investigate threatening emails, which artifact should you examine to trace messages back to the sender?

• A. Routing Table
• B. Firewall log
• C. Configuration files
• D. Email Header

Answer: (D)

Tracing an email’s origin hinges on the email header, which carries the message’s metadata about its journey. The header lists the servers the message passed through, the timestamps, and often the originating client or IP. By examining these Received lines from bottom to top, you can piece together the path the email took and identify where it started. Even though headers can be forged or manipulated, they’re the primary source for tracking provenance, and you can supplement them with SPF, DKIM, and DMARC checks for more confidence. Why the other artifacts aren’t as helpful here: a routing table shows how a particular device forwards packets and isn’t tied to a specific email’s origin. A firewall log records network connections and events, but not the complete provenance of an individual email message. Configuration files contain settings for systems or applications, not evidence about who sent a specific email.
