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?
Correct Answer: E
Explanation/Reference:
Explanation:
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) Reference: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipsla/configuration/15-mt/sla-15-mt-book/ sla_udp_jitter_voip.html
