Show answer and explanation
Correct answer: A
Explanation
IPsec is a widely-used encryption protocol that ensures confidentiality, integrity, and authentication of data transmitted over public networks. It is specifically designed to secure communications in scenarios like connecting branch offices over the internet, making it the best choice in this context.
- A. Correct.
IPsec (Internet Protocol Security) is designed for securing communications over public networks by providing encryption, authentication, and integrity. It is the most appropriate choice for this scenario.
- B. Incorrect.
Telnet is a protocol used for remote access but does not offer encryption, making it unsuitable for securing data transmission.
- C. Incorrect.
FTP (File Transfer Protocol) is used for transferring files but does not provide encryption by default, making it insecure for transmitting sensitive data.
- D. Incorrect.
WEP (Wired Equivalent Privacy) is an outdated wireless encryption protocol with known vulnerabilities, making it inappropriate for securing data over the public internet.
