Nokia Certified Network Associate (NCNA) — Question 40

Kahn solved the problem of interconnecting different networks using different protocols by pioneering a new protocol called TCP that was capable of:

Answer options

• A. Secure transmission of information.
• B. Enforcing a constant packet size to avoid discards.
• C. Allowing remote logins.
• D. Providing host to host connectivity with global addressing.

Correct answer: D

Explanation

The correct answer is D because TCP provides the essential functionality for establishing connections between different hosts, ensuring that data can be transmitted effectively across diverse networks. Options A, B, and C do not capture the primary purpose of TCP, which is focused on connectivity and addressing rather than security, packet size, or remote logins.
