In which situation would the Advanced Setup mode of the Create Virtual Service wizard be...

The Basic Setup mode is intended for common Virtual Service creation tasks, such as defining the application type and adding pool servers. Advanced Setup exposes the full Virtual Service configuration through multiple tabs and allows administrators to configure more detailed options that are not presented in the simplified workflow. VMware Avi documentation states that creating a Virtual Service in Advanced Setup allows configuration of all options through the different tabs. Analytics settings, including selecting or customizing analytics behavior for the Virtual Service, are advanced Virtual Service properties. By contrast, adding servers and choosing HTTPS are standard creation tasks, and adding a DNS name is not the key reason to require Advanced Setup in this question. Therefore, Advanced Setup is required for specifying analytics settings.
