The Salesforce Field Service Lightning certification I feel is one of the easier certifications among the rest that I have taken so far.
What helped tremendously on my learning was attending 2 day free training from Salesforce for Field Service Lightning. This quickly got me covering the core principles. While training was still fresh I prepared for the exam for a week. I already have an FSL org to play around so I went through the Trailhead Trailmix with constant checking on the help documentation for some concepts I did not understand.
There are 60 question plus 5 extra, you are given 90 minutes to complete the exam. Prerequisite to the certification is being Service Cloud certified.
Here are some key items to focus your study to nail the exam.
- Core Field Service Lightning
- Licenses and Permissions
- Operating Hours
- Service Territory
- Work Types
- Service Resource
- Service Crew
- Skills Requirement
- Service Appointment Lifecycle
- Service Reports
- Work Orders, Work Order Line Items
- Inventory Management
- Case Management
- Field Service Managed Package
- Dispatcher Console
- Scheduling Policies
- Transition Status & Profiles
- Mobile App
- FSL App vs Salesforce1 Features
- Global/Quick Actions
Hope this was useful. Goodluck!
