200-301 Question #1506: Real Exam Question with Answer & Explanation

Question

What is a characteristic of encryption in wireless networks?

Options

• Aprevents intercepted data from being easily read
• Buses a unidirectional handshake for authentication
• Cintercepts data threats before they attack a network
• Duses integrity checks to identify forgery attacks

Explanation

Encryption in wireless networks transforms data into an unreadable format, ensuring that if the data is intercepted, it cannot be easily deciphered by unauthorized parties.

Common mistakes.

• B. While wireless security protocols often involve authentication using handshakes, a unidirectional handshake is not a characteristic of encryption itself, which focuses on data confidentiality.
• C. Intercepting data threats before they attack a network is a function of security devices like firewalls or Intrusion Prevention Systems (IPS), not the direct function of encryption.
• D. Integrity checks are used to ensure data has not been tampered with (preventing forgery attacks) and are often included alongside encryption, but the fundamental characteristic of encryption itself is data confidentiality.
