What the exam expects

  • Configure a Lightning app's branding, navigation, profiles and utility bar in App Manager, and upgrade Classic apps.
  • Choose the compact layout, not the page layout, to change the record header, and assign it per record type.
  • Use Dynamic Forms visibility rules, knowing which objects support it and that visibility is not security.
  • Set up Path with key fields and guidance for each record type.
  • Predict how each Classic page layout element renders, or fails to render, in Lightning Experience.

Key terms: Lightning app (a branded bundle of navigation items); utility bar (a fixed footer of tools in one app); compact layout (the highlights panel's key fields); Dynamic Forms (fields and sections as separate page components); Path (a step bar built on a picklist).
