What is a method to resolve if the current storefront customer is a Salesforce B2B Commerce guest user in an apex class?
A . ccrz.cc_CallContext.currUser.isGuest
B . ccrz.cc_CallContext.isGuest
C . UserInfo.getUserType()
D . … UserType

Answer: B

Explanation:

A method to resolve if the current storefront customer is a Salesforce B2B Commerce guest user in an apex class is to use ccrz.cc_CallContext.isGuest. This property will return true if the current user is a guest user, or false otherwise. For example, if(ccrz.cc_CallContext.isGuest){ // do something for guest user } will execute some logic only for guest users.
