I don't recall IPSLA as a primary focus covered in any of my 300-115 study material. If any of the study material covered this topic it might have been on INE because they are very in-depth. I checked the blueprint for the new ENCOR 350-401 and IPSLA is definitely covered in section 4.5 "Configure and verify IPSLA".On Pearson's site they have the topic listed in their SWITCH lab exercises product in section 13 "IP SLA Echo Configuration" and challenge labs section 11 "Configure Network Monitoring Using IP SLA". This could be an indicator that it would be beneficial to learn for this exam. It's probably not a topic on the same level as EtherChannel, HSRP, VRRP, or GLBP yet good to know especially when transitioning into the new certification path in February 2020.
