A network engineer wants to baseline the network to determine suitability for real-time voice applications. Which IP SLA operation is best suited for this task?

A. ICMP -echo

B. UDP -connect

C. TCP -connect

D. ICMP -jitter

E. UDP -jitter

F. UDP -echo




 

Suggested Answer: E

The IP SLAs VoIP UDP jitter operation accurately simulates VoIP traffic using common codecs and calculates consistent voice quality scores (MOS and ICPIF) between Cisco devices in the network.
Note:
+ UDP Jitter: generates UDP traffic and measures Round-trip Delay, One-way Delay, One-way Jitter, One-way Packet Loss, and overall Connectivity.
+ UDP-echo: measures Round-trip Delay for UDP traffic.
There is also a special "UDP Jitter for VoIP" which can simulate various codecs and spits out voice quality scores (MOS, and ICPIF)
