Salesforce Certified Platform Developer II practice questions

1. Question 1 of 25

   What is a potential design issue with the following code? trigger accountTrigger on Account (before update){ Boolean processOpportunity = false; List<opportunity> opptysClosedLost = new List<opportunity>() List<opportunity> IstAllOpp = [select StageName from Opportunity where accountId IN :Trigger.newMap.keySet()]; if(!IstAllOpp.isEmpty()) processOpportunity = true; while(processOpportunity) { for(opportunity o : IstAllOpp) if(o.StageName == 'Closed - Lost') opptysClosedLost.add(o); processOpportunity = false; if(!opptysClosedLost.isEmpty()) delete opptysClosedLost;

   • ASOQL could be avoided by creating a formula field for StageName in Account from the related Opportunity
   • BThe code will result in a System.LimitException : Too many script statements error
   • CThe code will result in a System.DmlException:Entity_is_Deleted error
   • DThe code will result in a System.LimitException: Apex CPU time limit exceeded error

   Explanation

   Here is a better format of the code in case someone else wants to compare: trigger accountTrigger on Account (before update){ Boolean processOpportunity = false; List opptysClosedLost = new List (); List IstAllOpp = [select StageName from Opportunity where accountId IN :Trigger.newMap.keySet()]; if(!IstAllOpp.isEmpty()){ processOpportunity = true; while(processOpportunity){ for(opportunity o : IstAllOpp){if(o.StageName == 'Closed - Lost'){ opptysClosedLost.add(o); processOpportunity = false;}}} if(!opptysClosedLost.isEmpty()){delete opptysClosedLost;} The design flaw is that neither loop is necessary, a proper query could have collected the correct records to begin with and then delete them.

      I will just add my 2 cents here... The best option is D. The code will result in a System.LimitException: Apex CPU time limit exceeded error if the trigger is invoked with a large number of records. The other options are not correct because: A. Creating a formula field for StageName in Account will not avoid SOQL, it will just add an extra field to the Account object that may not be accurate or useful. B. The code will not result in a System.LimitException: Too many script statements error because the number of script statements is not dependent on the number of records processed by the trigger. C. The code will not result in a System.DmlException:Entity_is_Deleted error because the records are deleted only once and not queried again after deletion.

      I agree with it being a bad question. I can't tell where one code block begins and ends. A is irrelevant B is related to running too many lines of code, unlikely because a trigger runs in batches of 200 Maybe somehow it is C depending on how it is supposed to be written D is also unlikely unless this ended in an infinite loop

      No, not C, C is when a different record is added or updated and is associated with a deleted record: https://help.salesforce.com/s/articleView?id=000383970&type=1 So then my guess is that this was supposed to end in an infinite loop; in short, a code block that loops and never meets the exit condition.

2. Question 2 of 25

   What is a consideration when testing batch Apex? (Choose two.)

   • ATest methods must execute the batch with a scope size of less than 200 records

   Explanation

   Answer: AD “Make sure that the number of records inserted is less than or equal to the batch size of 200 because test methods can execute only one batch. You must also ensure that the Iterable returned by the start method matches the batch size.”

6. Question 6 of 25

   A developer wishes to improve runtime performance of Apex calls by caching results on the client. What is the best way to implement this?

   • ADecorate the server-side method with @AuraEnabled(cacheable=true).
   • BSet a cookie in the browser for use upon return to the page.
   • CCall the setStorable() method on the action in the JavaScript client-side code.
   • DDecorate the server-side method with @AuraEnabled(storable=true).

   Correct answer: A

   • A100%

   Explanation

   Prior to Winter ’19, to cache data returned from an Apex method, you had to call setStorable() in JavaScript code on every action that called the Apex method. Now you can mark the Apex method as storable (cacheable) and get rid of any setStorable() calls in JavaScript code.

For API version of 44.0 or higher, you must mark the Apex method as storable (cacheable) and you can get rid of any setStorable() calls in JavaScript code.

   Explanation

   D is correct. Either remote object or @remoteAction requires a JS callback,promise, async&await function to parse the JSON result from back-End to client side. For example, you can easily construct a wrapper class using @remoteAction in Apex where information from multiple queries or proxy variables can be brought together. For remote object you will need JS to do "promise.all" in order to cover that kind of wrapper in Apex, which will be very complex and hard to read

8. Question 8 of 25

   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?

   • AUse the REST API as well as the SOAP API to effectively double the API calls allowed in a 24-hour period.
   • BCreate an Inbound Message that, using Flow, can do all of the logic the integration code was doing.
   • CWrite a custom Apex web service that, given an email address, does all of the logic the integration code was doing.
   • DCreate several Apex InboundEmailHandlers to accept calls from the third-party system, thus bypassing the API limits.

9. Question 9 of 25

   Universal Containers wants to use a Customer Community with Customer Community Plus licenses so their customers can track how many containers they are renting and when they are due back. Many of their customers are global companies with complex Account hierarchies, representing various departments within the same organization. One of the requirements is that certain community users within the same Account hierarchy be able to see several departments' containers, based on a junction object that relates the Contact to the various Account records that represent the departments. Which solution solves these requirements?

   • AA Visualforce page that uses a Custom Controller that specifies without sharing to expose the records
   • BA Custom List View on the junction object with filters that will show the proper records based on owner
   • CA Custom Report Type and a report Lightning Component on the Community Home Page
   • DAn Apex Trigger that creates Apex Managed Sharing records based on the junction object's relationships

      C. A Custom Report Type and a report Lightning Component on the Community Home Page: This would provide a way for users to see data they have access to, but like Custom List Views, reporting respects the organization’s sharing model. Reports alone cannot grant additional access beyond what the user already has. D. An Apex Trigger that creates Apex Managed Sharing records based on the junction object's relationships: This approach uses Apex Managed Sharing to programmatically share records with users based on complex sharing requirements that cannot be met with standard sharing functionality. Apex Managed Sharing is specifically designed to handle scenarios where sharing needs to go beyond the typical role hierarchy or sharing rules.

      This approach lets you programmatically share container records with the correct users based on the related junction object. Given that the requirements involve custom sharing across Account hierarchies (multiple departments), using Apex managed sharing ensures that community users can access the appropriate records despite the standard sharing settings.

       Return data types can be any of the following. Simple—String, Integer, and so on. See Basic Types for details. sObject—standard and custom sObjects are both supported. See Standard and Custom Object Types. Apex—an instance of an Apex class. (Most often a custom class.) See Custom Apex Class Types. You can’t use an Apex inner class as a return value for an Apex method that's called by an Aura component. Collection—a collection of any of the other types. See Collection Types.

14. Question 14 of 25

    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?

    • AA Visualforce page that can make a real-time Apex callout to display and save the pricing back in Salesforce
    • BAn Apex trigger that upon saving the Order will make a real-time Apex callout, saving the pricing back in Salesforce
    • CA Process Builder process and Outbound Message to fetch the pricing upon save and store the pricing in Salesforce
    • DAn ETL tool to process batches of newly saved Orders every few minutes to store the pricing back in Salesforce

       B. This is because custom metadata fields can be used for secret storage in a similar way to custom settings, but with more advantages(1)(2). For proper secrecy, you can set their visibility to ”Protected” and contain them within a managed package(1)(2). Protected custom metadata API fields are a great choice for storing API keys or other secret keys, for example12. 1: https://trailhead.salesforce.com/content/learn/modules/secure-secrets-storage/protect-secrets-using-platform-features 2: https://developer.salesforce.com/docs/atlas.en-us.secure_coding_guide.meta/secure_coding_guide/secure_coding_storing_sensitive_data.htm

       When performing a callout after DML in the same transaction, Salesforce requires that there is no uncommitted work pending. Using an @future method (with callout=true) to perform the callout asynchronously moves the callout into its own transaction, thereby avoiding the "uncommitted work pending" error.

    Only 60% agreed on this answer — treat it as contested rather than settled.

    Explanation

    Aditya97 I think D. COUNT() could be right because: Queries that include aggregate functions are still subject to the limit on total number of query rows i.e 50,000. All aggregate functions other than COUNT() or COUNT(fieldname) include each row used by the aggregation as a query row for the purposes of limit tracking. For COUNT() or COUNT(fieldname) queries, limits are counted as one query row, unless the query contains a GROUP BY clause, in which case one query row per grouping is consumed.

       Aditya97 I think D. COUNT() could be right because: Queries that include aggregate functions are still subject to the limit on total number of query rows i.e 50,000. All aggregate functions other than COUNT() or COUNT(fieldname) include each row used by the aggregation as a query row for the purposes of limit tracking. For COUNT() or COUNT(fieldname) queries, limits are counted as one query row, unless the query contains a GROUP BY clause, in which case one query row per grouping is consumed.

       The answer is D. Using the basic COUNT() function returns an integer, not an aggregate result, so there is even less code to write. Also, the limit is on the number of rows retrieved, not queried against. https://developer.salesforce.com/docs/atlas.en-us.soql_sosl.meta/soql_sosl/sforce_api_calls_soql_select_count.htm https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/langCon_apex_SOQL_agg_fns.htm

20. Question 20 of 25

    A developer is asked to build a solution that will automatically send an email to the Customer when an Opportunity stage changes. The solution must scale to allow for 10,000 emails per day. The criteria to send the email should be evaluated after all Workflow Rules have fired. What is the optimal way to accomplish this?

    • AUse a MassEmailMessage() with an Apex Trigger.
    • BUse a Workflow Email Alert.
    • CUse an Email Alert with Process Builder.
    • DUse a SingleEmailMessage() with an Apex Trigger.

If there are workflow field updates: Updates the record again. Runs system validations again. Custom validation rules, flows, duplicate rules, processes, and escalation rules aren’t run again. Executes before update triggers and after update triggers, regardless of the record operation (insert or update), one more time (and only one more time) Can use A. Use a MassEmailMessage() with an Apex Trigger.

       1. Queueable Jobs can contain the member variable as SObjects or custom Apex Types. 2. When using queueable jobs it will make the AsyncApexJob which we can monitor like Scheduled jobs. 3.

       Methods with the future annotation must be static methods, and can only return a void type. The specified parameters must be primitive data types, arrays of primitive data types, or collections of primitive data types.

    Found the below two points in the Apex Developer Guide (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_testing_unit_tests_running.htm): 1. You can use the runTests() call from the SOAP API to run tests synchronously. 2. You can also run tests using the Tooling REST API. Use the /runTestsAsynchronous/ and /runTestsSynchronous/ endpoints to run tests asynchronously or synchronously. So the answer to the question should be Tooling API, SOAP API and Metadata API, because Streaming API is about events and notifications, and there is no such thing as Test API.
