Fill in the blank with the appropriate term. A _______________device is used for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits. Answer: biometric

Question

Options

• AWireless sniffer
• BSpectrum analyzer
• CProtocol analyzer
• DPerformance Monitor

• A
  85% (34)
• B
  10% (4)
• D
  5% (2)

Explanation

There appears to be a mismatch in this question - the fill-in-the-blank answer ("biometric") and the multiple-choice options (wireless sniffer, spectrum analyzer, protocol analyzer, performance monitor) belong to two different questions that were accidentally merged. None of the listed choices relate to biometric devices.

Here's what each part actually covers:

Fill-in-the-blank (biometric): A biometric device identifies humans using unique physical or behavioral traits - fingerprints, retinal scans, voice patterns, or gait. Memory tip: "bio" = life/body, "metric" = measurement - it literally measures your body.

Multiple-choice A & C (likely a separate network analysis question):

• A. Wireless sniffer - captures wireless network traffic packets; correct for network capture tasks
• C. Protocol analyzer - inspects and decodes network protocol data; also correct for traffic analysis
• B. Spectrum analyzer - measures radio frequency signal strength, not packet content; wrong for protocol-level analysis
• D. Performance Monitor - tracks system resource usage (CPU, RAM); unrelated to traffic capture

Recommendation: Double-check your source material - these look like two separate exam items that were copy-pasted together incorrectly. Treating them as one question could cause confusion on your actual exam.
