N10-005 Question #776: Real Exam Question with Answer & Explanation
The correct answer is A: Confidentiality. Encryption scrambles data into an unreadable ciphertext that only authorized parties with the correct key can decipher, directly providing confidentiality.
Question
Encryption provides which of the following to data being transferred across the network?
Options
- AConfidentiality
- BResistance to Jitter
- CHigh Availability
- DData Integrity
Explanation
Encryption scrambles data into an unreadable ciphertext that only authorized parties with the correct key can decipher, directly providing confidentiality.
Common mistakes.
- B. Resistance to jitter is a network quality characteristic related to consistent packet delivery timing, typically addressed by QoS mechanisms and buffering, not encryption.
- C. High availability refers to system uptime and redundancy strategies such as failover clustering or load balancing, which are unrelated to encryption.
- D. Data integrity - ensuring data has not been altered - is provided by cryptographic hashing (e.g., SHA-256) or HMACs, not encryption alone.
