N10-005 Question #863: Real Exam Question with Answer & Explanation

The correct answer is C: Decrease signal strength.. War driving is the practice of scanning for wireless networks from outside a building (e.g., from a vehicle). Decreasing the WAP transmit power limits the signal's physical range so it does not extend beyond the building's walls, making the network harder to detect from the outsi

Question

When installing new WAPs in a small office, which of the following is the BEST way to physically mitigate the threats from war driving?

Options

AImplement multiple wireless encryption techniques.
BImplement PoE on each WAP.
CDecrease signal strength.
DIncrease signal strength.

Explanation

War driving is the practice of scanning for wireless networks from outside a building (e.g., from a vehicle). Decreasing the WAP transmit power limits the signal's physical range so it does not extend beyond the building's walls, making the network harder to detect from the outside. This is a physical mitigation because it directly restricts the radio frequency footprint. Encryption (option A) is a logical control. PoE (option B) is a power delivery method unrelated to security. Increasing signal strength (option D) would make the problem worse.
