CompTIA Network+ (N10-009) — Question 196

Which of the following is the most likely function to be decremented when a tool is used to measure the distance between two locations on the internet?

Answer options

• A. GRE
• B. TTL
• C. VPN
• D. QoS

Correct answer: B

Explanation

The correct answer is B, TTL (Time to Live), which is decremented each time a packet passes through a router, thus measuring the distance in hops. The other options, GRE, VPN, and QoS, serve different purposes in networking and do not relate to measuring distance in the same way.
