NEW QUESTION # 27
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. write a custom Apex web service that, given an email address, does all of the logic the integration code was doing.
- C. Create several Apex InboundEmailHandlers to accept calls from the third-party system, thus bypassing the API limits.
- D. Create an Inbound Message that, using Flow, can do all of the logic the integration code was doing.
Answer: C
NEW QUESTION # 28
A developer notices the execution of all the test methods in a class takes a long time to run, due to the initial setup of all the test data that is needed to perform the tests. What should the developer do to speed up test execution?
- A. Ensure proper usage of test data factory in all test methods.
- B. Define a method that creates test data and annotate with @testSetup.
- C. Reduce the amount of test methods in the class.
- D. Define a method that creates test data and annotate with @createData.
Answer: B
Explanation:
The @testSetup annotation allows you to define a method that creates test data and is executed only once before all the test methods in a class. This can speed up test execution by reducing the number of DML operations and avoiding code duplication. The @createData annotation does not exist in Apex. The test data factory is a design pattern that can be used to create test data, but it does not guarantee faster execution. Reducing the amount of test methods in a class may compromise the test coverage and quality. Reference: [Test Setup Methods], [Test Data Factory]
NEW QUESTION # 29
A large company uses Salesforce across several departments. Each department has its own Salesforce Administrator. It was agreed that each Administrator would have their own sandbox in which to test changes.

- A. The administrators are deploying their own Change Sets, thus deleting each other's fields from the objects in production.
- B. A sandbox should be created to use as a unified testing environment instead of deploying Change Sets directly to production.
- C. The administrators are deploying their own Change Sets over each other, thus replacing entire Page Layouts and Workflows in Production
- D. Page Layouts should never be deployed via Change Sets, as this causes Workflows and Field-level Security to be reset and fields to disappear.
Answer: B,C

NEW QUESTION # 41
Which three actions must be completed in a Lightning web component for a JavaScript file In a static resource to be loaded? Choose 3 answers
- A. Call loadScript.
- B. Reference the static resource in a <script> tag.
- C. Append the static resource to the DOM.
- D. Import a method from the platformResourceLoader.
- E. Import the static resource.
Answer: A,D,E
Explanation:
The three actions that must be completed in a Lightning web component for a JavaScript file in a static resource to be loaded are to import the static resource, call loadScript, and import a method from the platformResourceLoader. Importing the static resource allows the developer to reference the JavaScript file by name, and use the @salesforce/resourceUrl annotation to assign the URL of the file to a property. Calling loadScript allows the developer to load the JavaScript file dynamically, and use a callback function to handle the success or failure of the loading. Importing a method from the platformResourceLoader allows the developer to use the loadScript method, which is a utility method that is part of the platformResourceLoader module. Referencing the static resource in a <script> tag will not work, as the <script> tag is not supported in the Lightning web component template, and it will not load the JavaScript file. Appending the static resource to the DOM will not work, as it is not a valid way to load a JavaScript file in a Lightning web component, and it will not execute the code in the file. Reference: [Use Third-Party JavaScript Libraries], [Lightning Web Components Developer Guide]
