CCNA: Cisco Certified Network Associate — Question 1308

What is a feature of TFTP?

Answer options

• A. offers anonymous user login ability
• B. uses two separate connections for control and data traffic
• C. relies on the well-known TCP port 20 to transmit data
• D. provides secure data transfer

Correct answer: A

Explanation

The correct answer is A, as TFTP allows for anonymous user logins, which is a key feature of the protocol. Option B is incorrect because TFTP uses a single connection for both control and data, unlike protocols that separate these. Option C is wrong since TFTP operates over UDP and does not use TCP port 20 for data transfer. Option D is also incorrect, as TFTP does not provide secure data transfer.
