   What is a benefit of JavaScript remoting over Visualforce Remote Objects?

   • AAllows for specified re-render targets
   • BDoes not require any Apex code
   • CDoes not require any JavaScript code
   • DSupports complex server-side application logic

   Show answer

   Answer: D

   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

   If you wanted to create a record following the update of another (with data from the source object), what is the most customizable approach?

   • AWorkflow Rule
   • BProcess Builder
   • CAfter update Trigger
   • DFlow

   Show answer

   Answer: C

   Explanation

   I think the answer should be D. Salesforce recommends Flow as Process Builder is going to decommission or not preferred/best practice approach.

7. Question 87 · 279 in bank

   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.

   Show answer

   Answer: C

   Explanation

   C is correct. InboundEmailHandler is used to add additional logic on all incoming email to salesforce. It has nothing to do with Integration in term of REST or SOAP webservice

8. Question 88 · 279 in bank

   If the "PageReference.setRedirect" Apex function is set to True, what type of request is made?

   • AGet request
   • BPostback request
   • CIf PageReference points to the same controller and subset of extensions, postback request, otherwise get request

   Show answer

   Answer: A

   Explanation

   You can use the setRedirect attribute on a pageReference to control whether a postback or get request is executed. If setRedirect is set to true, a get request is executed. Setting it to false does not ignore the restriction that a postback request will be executed if and only if the target uses the same controller and a proper subset of extensions. If setRedirect is set to false, and the target does not meet those requirements, a get request will be made.

   Universal Container needs to integrate with an external system. Every time an Account record is updated to meet certain criteria, a SOAP message must be sent to a third party end-point with the following information: Name, Industry, AccountNumber, and Rating. The lead developer for the org is considering using Workflow rules instead of Apex triggers to fulfill the above requirements. What are three benefits of using Workflow rules as opposed to Apex triggers? (Choose three.)

   • AA SOAP message can send more than 100 notifications
   • BTwo-way SSL is supported by including a client certificate
   • COutbound messages prevent circular changes out-of-the-box
   • DRetry logic for outbound messages is enabled out-of-the-box
   • ETracking outbound message delivery is enabled out-of-the-box

10. Question 90 · 279 in bank

    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

    Show answer

    Answer: D

    Explanation

    Its C, altough its possible making with Apex Trigger, Salesforce Alwats recommend to use the standard tools before use code.
