PDI Question #109: Real Exam Question with Answer & Explanation

Question

A developer must write anApex method that will be called from a lightning component. The method may delete an Account stored in the accountRec variable. Which method should a developer use to ensure only users that should be able to delete Accounts can successfully perform deletion?

Options

• AaccountRec., isDeletable()
• BAccount, isDeletable ()
• CAccountRec, ObjecType, ieDeletable ()
• DSchena, sobjectType, Account, isDeletetable ()

Explanation

To ensure an Apex method respects user permissions before deleting an Account, the developer must use Schema.sObjectType.Account.isDeletable() to check if the current user has delete access on the Account object.

Common mistakes.

• A. accountRec.isDeletable() is not a valid Apex method for checking delete permissions on a specific SObject record variable.
• B. Account.isDeletable() is incomplete and incorrect syntax for checking object-level delete permissions; it should be accessed through Schema.sObjectType.
• C. AccountRec.ObjecType.isDeletable() contains a typo (ObjecType) and incorrect syntax for checking delete permissions.
