CompTIA Network+ (N10-009) — Question 502

A network administrator is troubleshooting an issue with a user's IP address. Which of the following layers of the OSI model should be considered?

Answer options

• A. Data link
• B. Network
• C. Session
• D. Presentation

Correct answer: B

Explanation

The correct answer is B, Network, because IP addresses operate at this layer, which is responsible for routing packets across different networks. Options A (Data link), C (Session), and D (Presentation) do not deal with the IP addressing functionality necessary for this troubleshooting scenario.
