[All Certified Platform Developer II Questions]

Refer to the code snippet below:

As part of an integration development effort, a developer is tasked to create an Apex method that solely relies on the use of foreign identifiers in order to relate new contact records to existing Accounts in Salesforce. The account object contains a field marked as an external ID, the API Name of this field is Legacy_Id_c.

What is the most efficient way to instantiate the parentAccount variable on line 02 to ensure the newly created contact is properly related to the Account?

A. Account parentAccount = new Account(Legacy_Id_c = externalIdentifier);
B. Account parentAccount = [SELECT Id FROM Account WHERE Legacy_Id_c = :externalIdentifier].Id;
C. Account parentAccount = [SELECT Id FROM Account WHERE Legacy_Id_c = :externalIdentifier];
D. Account parentAccount = new Account();
parentAccount.Id = externalIdentifier;

i think it is C because newContact.Account expect an account with the right id to be linked, the external id even if it is uniq (that is not forced) will not be sufficient to link the two object it is not a standard behavior to link two object with other thing that an id

Selected Answer: C

C. Both A and D create a new parent account, which is not needed since the account is already in the system as stated by the question. Therefore that leaves B and C. It cannot be B because that does not follow proper formatting and assignment rules, plus the Id is already indicated as the field to get from the SOQL query. That means the answer is C.
