I took the ArcGIS Online Administration Specialty 19-001, as there is no new version.
I found many questions outdated, referring to names and limitations that do no longer exist.
One example I remember is "What do you need to configure, to enable access to a GeoNet Infrastructure Group".
The final survey asked for the latest ArcGIS versions I use, offering ArcGIS Desktop 10.4 as "latest version" 😉
It would be great if you could update the certification questions.
