Palo Alto Networks System Engineer – SASE — Question 27

Which App Response Time metric is the measure of network latency?

Answer options

• A. Round Trip Time (RTT)
• B. Server Response Time (SRT)
• C. Network Transfer Time (NTTn)
• D. UDP Response Time (UDP-TRT)

Correct answer: A

Explanation

Round Trip Time (RTT) measures the time it takes for a packet to travel to a destination and back, which directly reflects network latency. The other options, such as Server Response Time (SRT) and Network Transfer Time (NTTn), pertain to different aspects of response times that do not specifically measure network latency.
