GCIH · Question #744
The following event snippet was recorded by which type of logging device? 1660582288.951 185 192.168.42.109 TCP_MISS/208 1856
The correct answer is A. Web proxy. The log entry follows the Squid proxy log format, which includes a timestamp, elapsed time, client IP, result code, bytes transferred, and request method.

Why each option
The log entry follows the Squid proxy log format, which includes a timestamp, elapsed time, client IP, result code, bytes transferred, and request method.
The format matches a Squid web proxy access log. The fields are: Unix timestamp (1660582288.951), elapsed milliseconds (185), client IP (192.168.42.109), result/status code (TCP_MISS/208), and bytes (1856). TCP_MISS is a Squid-specific cache result code indicating the request was not served from cache, which is unique to web proxy logging.
Endpoint detection logs typically include process names, file paths, registry keys, and user context - not TCP cache result codes or byte counts in this format.
Network flow records (NetFlow/IPFIX) capture src/dst IP, src/dst port, protocol, and byte counts in a structured flow record format, not proxy cache result codes like TCP_MISS.
Stateful firewall logs record allow/deny actions with src/dst IP, port, protocol, and interface - they do not produce TCP_MISS cache result codes or elapsed time fields.
