CompTIA Network+ (N10-008) — Question 31

Which of the following BEST describes a North-South traffic flow?

Answer options

• A. A public Internet user accessing a published web server
• B. A database server communicating with another clustered database server
• C. A Layer 3 switch advertising routes to a router
• D. A management application connecting to managed devices

Correct answer: A

Explanation

North-South traffic flow refers to data moving between external users and internal resources, which is exemplified by option A where a public Internet user accesses a web server. Options B, C, and D describe intra-network communications or internal management, which do not represent the flow of traffic in and out of a network.
