200-301 Question 400
Single answerA network administrator is configuring a small business network and wants to ensure the integrity and confidentiality of data being transmitted over the internet. Which security technology would be the MOST appropriate to achieve this goal?
- A
VPN (Virtual Private Network)
- B
NAT (Network Address Translation)
- C
ACL (Access Control List)
- D
Port Mirroring
Show answer and explanation
Correct answer: A
Explanation
VPN (Virtual Private Network) is the correct answer because it provides both data encryption and integrity verification, ensuring secure communication over public networks. The other options do not directly address the need for confidentiality and integrity of transmitted data in the same way.
- A. Correct.
VPN (Virtual Private Network) ensures data confidentiality and integrity by encrypting the data being transmitted over public networks, making it the most suitable choice for securing transmitted data.
- B. Incorrect.
NAT (Network Address Translation) is used for translating private IP addresses to public IP addresses and does not provide encryption or ensure data integrity.
- C. Incorrect.
ACL (Access Control List) is used to control traffic flow and permissions based on predefined rules, but it does not directly ensure data confidentiality and integrity.
- D. Incorrect.
Port Mirroring is used for monitoring network traffic by duplicating packets to a specific port, but it does not provide any encryption or data security.
