Recently a Salesforce org’s integration failed because it exceeded the number of allowed API calls in a 24-hour period. The integration handles a near real-time, complex insertion of data into Salesforce.
The flow of data is as follows:
✑ The integration looks up Contact records with a given email address and, if found, the integration adds a Task to the first matching Contact it finds.
✑ If a match is not found, the integration looks up Lead records with a given email address and, if found, the integration adds a Task to the first matching Lead it finds.
✑ If a match is not found, the integration will create a Lead and a Task for that newly created Lead.
What is one way in which the integration can stay near real-time, but not exceed the number of allowed API calls in a 24-hour period?
A. Use the REST API as well as the SOAP API to effectively double the API calls allowed in a 24-hour period.
B. Create an Inbound Message that, using Flow, can do all of the logic the integration code was doing.
C. Write a custom Apex web service that, given an email address, does all of the logic the integration code was doing.
D. Create several Apex InboundEmailHandlers to accept calls from the third-party system, thus bypassing the API limits.

An environment has two Apex Triggers: an after-update trigger on Account and an after-update trigger on Contact. The Account after-update trigger fires whenever an Account’s address is updated, and it updates every associated Contact with that address. The Contact after-update trigger fires on every edit, and it updates every Campaign Member record related to the Contact with the Contact’s state.
Consider the following: A mass update of 200 Account records’ addresses, where each Account has 50 Contacts. Each Contact has 1 Campaign Member. This means there are 10,000 Contact records across the Accounts and 10,000 Campaign Member records across the contacts.
What will happen when the mass update occurs?
A. The mass update will fail, since the two triggers fire in the same context, thus exceeding the number of records processed by DML statements. Most Voted
B. There will be no error, since each trigger fires within its own context and each trigger does not exceed the limit of the number of records processed by DML statements.
C. There will be no error, since the limit on the number of records processed by DML statements is 50,000.
D. The mass update of Account address will succeed, but the Contact address updates will fail due to exceeding number of records processed by DML statements.
A. The mass update will fail, since the two triggers fire in the same context, thus exceeding the number of records processed by DML statements.
A company has many different unit test methods that create Account records as part of their data setup. A new required field was added to the Account and now all of the unit tests fail.

B. Create a TestDataFactory class that serves as the single place to create Accounts for unit tests and set the required field there.
C. Change the required field to be a validation rule that excludes the System Administrator profile.
D. Add the required field to the data setup for all of the unit tests.
B. Create a TestDataFactory class that serves as the single place to create Accounts for unit tests and set the required field there.
A user receives the generic “An internal server error has occurred” while interacting with a custom Lightning Component.

Sometimes events on Salesforce need to be handled by an external system due to the scale or type of process being executed. Consider the use case of a user in
Salesforce needing to get pricing for an order they are building in Salesforce while on the phone with a customer.
The pricing logic already exists in a third-party system. Instead of recreating this logic in Salesforce, it will be leveraged by making a request of the third-party system. The response, in this case the pricing, will be returned and stored back in Salesforce.
What is the optimal solution?
A. A Visualforce page that can make a real-time Apex callout to display and save the pricing back in Salesforce
B. An Apex trigger that upon saving the Order will make a real-time Apex callout, saving the pricing back in Salesforce
C. A Process Builder process and Outbound Message to fetch the pricing upon save and store the pricing in Salesforce

@isTest
static void testIncrement() {
Account acct = new Account(Name = ‘Test’);
acct.Number_Of_Times_Viewed__c = 0;
insert acct;
AuditUtil.incrementViewed(acct.Id);
Account acctAfter = [SELECT Number_Of_Times_Viewed__c FROM Account WHERE Id = :acct.Id][0]
System.assertEquals(1, acctAfter.Number_Of_Times_Viewed__c);
}
The test method above calls an @future method that increments the Number_of_Times_Viewed__c value. The assertion is failing because the
Number_of_Times_Viewed__c equals 0.
What is the optimal way to fix this?
A. Change the initialization to acct.Number_Of_Times_Viewed__c = 1.
B. Add Test.startTest() before and Test.stopTest() after AuditUtil.incrementViewed.
C. Add Test.startTest() before and Test.stopTest() after insert acct.
D. Change the assertion to System.assertEquals(0, acctAfter.Number_Of_Times_Viewed__c).
B. Add Test.startTest() before and Test.stopTest() after AuditUtil.incrementViewed.
A company represents their customers as Accounts that have an External ID field called Customer_Number__c. They have a custom Order (Order__c) object, with a Lookup to Account, to represent Orders that are placed in their external order management system (OMS). When an order is fulfilled in the OMS, a REST call to Salesforce should be made that creates an Order record in Salesforce and relates it to the proper Account.
What is the optimal way to implement this?

An Apex Trigger creates a Contract record every time an Opportunity record is marked as Closed and Won. This trigger is working great, except (due to a recent acquisition) historical Opportunity records need to be loaded into the Salesforce instance.
When a test batch of records is loaded, the Apex Trigger creates Contract records. A developer is tasked with preventing Contract records from being created when mass loading the Opportunities, but the daily users still need to have the Contract records created.
What is the most extendable way to update the Apex Trigger to accomplish this?
A. Use a Hierarchy Custom Setting to disable the Trigger for the user who does the data loading.
B. Use a List Custom Setting to disable the Trigger for the user who does the data loading.
