Q8. Which one of the following IP SLA operation measures round-trip delay of UDP traffic ?
A. UDP Jitter
B. ICMP Echo
C. UDP Echo
D. ICMP Path Jitter
Correct Answer: C
Explanation:
UDP Jitter: Measures round-trip delay, one-way
delay,one-way jitter, one-way packet loss, and connectivity testing
of networks that carry UDP traffic, such as voice. Note that one-way
delay requires time synchronization between source and target
routers.
ICMP Path Jitter: Measures hop-by-hop
jitter, packet loss, and delay measurement statistics in an IP
network.
UDP Echo: Measures round-trip delay of
UDP traffic.
ICMP Echo: Measures round-trip
delay for the full path.
