CompTIA Network+ (N10-008) — Question 814

Which of the following routing protocols is generally used by major ISPs for handling large-scale internet traffic?

Answer options

• A. RIP
• B. EIGRP
• C. OSPF
• D. BGP

Correct answer: D

Explanation

BGP (Border Gateway Protocol) is the standard for routing between different autonomous systems on the internet, making it essential for ISPs managing large-scale traffic. RIP, EIGRP, and OSPF are more suited for smaller networks and do not scale as effectively for the vast internet infrastructure that ISPs handle.
