Exam 400-101 topic 2 question 261 discussion

IP SLAs uses active traffic monitoring--the generation of traffic in a continuous, reliable, and predictable manner--for measuring network performance. Being Layer-2 transport independent, IP SLAs can be configured end-to-end over disparate networks to best reflect the metrics that an end-user is likely to experience. IP SLAs can send SNMP traps that are triggered by events such as One-way mean opinion score (MOS) ABD all right.

B&D, for B, check " Being Layer-2 transport independent, IP SLAs can be configured end-to-end over disparate networks to best reflect the metrics that an end-user is likely to experience. Performance metrics collected by IP SLAs operations include the following: ..." https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipsla/configuration/15-mt/sla-15-mt-book/sla_overview.html

IT's A + B. Without any doubt it can measure MOS. And because it's IP based it has no dependency to the Layer-2. D is a bit wrong, because IP SLA isn't a method to monitor traffic. IP SLA generates traffic and analyses the answers.

2 things I measure MOS using IP SLA and its well documented on the Cisco website. This is copied direct from cisco.com Cisco IP SLAs uses active traffic monitoring--the generation of traffic in a continuous, reliable, and predictable manner--for measuring network performance. IP SLAs sends data across the network to measure performance between multiple network locations or across multiple network paths.

I think that A,B and D are correct. Maybe we should choose three?

Correct answers are AB
