Question #11
A company processes Orders within their Salesforce instance. When an Order's status changes to 'Paid' it must notify the company's order management system
(OMS). The OMS exposes SOAP web service endpoints to listen for when to retrieve the data from Salesforce.
What is the optimal method to implement this?
  1. A
    Generate the Enterprise WSDL and use it to make a callout to the OMS.
  2. B
    Generate the Partner WSDL and use it to make a callout to the OMS.
  3. C
    Create an Outbound Message that contains the session ID and send it to the OMS.
  4. D
    Create an Apex trigger and make a callout to the OMS from the trigger.

Correct Answer:
A

Question #12

Consider the Apex controller above, that is called from a Lightning Aura Component.
What is wrong with it?
  1. A
    Line 1: class must be global
  2. B
    Lines 1 and 6: class and method must be global
  3. C
    Line 6: method must be static
  4. D
    Line 8: method must first serialize the list to JSON before returning

Correct Answer:
C

  2. B
    Call the Apex class method from a testMethod instead of the testSetup method.
  3. C
    Add @testVisible to the method in the class the developer is testing.
  4. D
    Use system.assert() in testSetup to verify the values are being returned.

Correct Answer:
B

Question #16
A developer is asked to update data in an org based on new business rules. The new rules state that Accounts with the type set to 'Customer' should have a status of 'Active', and Accounts with the type set to 'Prospect' should have a status of 'Pending'. No other changes to data should be made.
Which code block will accurately meet the business requirements?
  1. A
    Map<String, String> statusMap = new Map<String, String>{'Customer'=>'Active', 'Prospect'=>'Pending'} List<Account> accountUpdates = new List<Account>(); for ( Account a : [SELECT Id, Type FROM Account]){ if ( statusMap.containsKey(a.Type) ) { a.Status = a.Type == 'Customer' ? 'Active' : 'Pending'; } accountUpdates.add(a); } update accountUpdates;
  2. B
    Map<String, String> statusMap = new Map<String, String>{'Customer'=>'Active', 'Prospect'=>'Pending'} List<Account> accountUpdates = new List<Account>(); for ( Account a : [SELECT Id, Type FROM Account WHERE Status IN :statusMap.keySet()]){ a.Status = statusMap.get(a.Type); accountUpdates.add(a); } update accountUpdates;
  3. C
    List<Account> accountUpdates = new List<Account>(); for ( Account a : [SELECT Id, Type FROM Account]){ if ( String.isNotBlank(a.Type) && a.Type == 'Customer' ){ a.Status = 'Active'; } if ( String.isNotBlank(a.Type) && a.Type == 'Prospect' ){ a.Status = 'Pending'; } accountUpdates.add(a); } update accountUpdades;
  4. D
    List<Account> accountUpdates = new List<Account>(); for ( Account a : [SELECT Id, Type FROM Account]){ a.Status = a.Type == 'Customer' ? 'Active' : 'Pending'; accountUpdates.add(a); } update accountUpdates;

Correct Answer:

Question #19
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?
  1. A
    Use the REST API as well as the SOAP API to effectively double the API calls allowed in a 24-hour period.
  2. B
    Create an Inbound Message that, using Flow, can do all of the logic the integration code was doing.
  3. C
    Write a custom Apex web service that, given an email address, does all of the logic the integration code was doing.
  4. D
    Create several Apex InboundEmailHandlers to accept calls from the third-party system, thus bypassing the API limits.

Correct Answer:
D

  2. B
    <design:component label="Account FS Component"> <design:attribute name="fieldSetName" label="Field Set Name" /> <sfdc:objects> <sfdc:object>Account</sfdc:object> </sfdc:objects> </design:component>
  3. C
    <design:component label="Account FS Component"> <aura:attribute name="fieldSetName" label="Field Set Name" /> <sfdc:objects> <sfdc:object>FieldSet</sfdc:object> </sfdc:objects> </design:component>
  4. D
    <design:component label="Account FS Component"> <aura:attribute name="fieldSetName" label="Field Set Name" /> <sfdc:objects> <sfdc:object>Account</sfdc:object> </sfdc:objects> </design:component>

Correct Answer:
B
