NEW QUESTION # 46
Universal Containers recently transitioned from Classic to Lighting Experience. One of its business processes requires certain value from the opportunity object to be sent via HTTP REST callout to its external order management system based on a user-initiated action on the opportunity page. Example values are as follow
* Name
* Amount
* Account
Which two methods should the developer implement to fulfill the business requirement? (Choose 2 answers)
- A. Create a Lightning component that performs the HTTP REST callout, and use a Lightning Action to expose the component on the Opportunity detail page.
- B. Create an after update trigger on the Opportunity object that calls a helper method using
@Future(Callout=true) to perform the HTTP REST callout. - C. Create a Visualforce page that performs the HTTP REST callout, and use a Visualforce quick action to expose the component on the Opportunity detail page.
- D. Create a Process Builder on the Opportunity object that executes an Apex immediate action to perform the HTTP REST callout whenever the Opportunity is updated.
Answer: A,C
Explanation:
The developer should implement either a Lightning component or a Visualforce page that performs the HTTP REST callout, and use a Lightning Action or a Visualforce quick action to expose the component on the Opportunity detail page. These methods allow the developer to create a user interface that can capture the user input and trigger the callout based on a user-initiated action. The Lightning component or the Visualforce page can use the Apex controller to invoke the HTTP callout using the built-in HTTP classes, such as HttpRequest, HttpResponse, and Http. The Lightning Action or the Visualforce quick action can be added to the page layout of the Opportunity object and configured to display the component in a modal dialog or a panel.
Creating a Process Builder or an after update trigger to perform the HTTP REST callout is not a suitable method for this business requirement, because these methods do not provide a user interface or a user-initiated action. The Process Builder or the trigger would execute the callout whenever the Opportunity is updated, regardless of the user input or intention. This could result in unnecessary or unwanted callouts, as well as hitting the governor limits for callouts.

NEW QUESTION # 50
What are two ways a developer can get the status of an enquered job for a class that queueable interface?
Choose 2 answers
- A. View the apex status Page
- B. View the apex Jobs page
- C. Query the AsyncApexJobe object
- D. View the apex flex Queue
Answer: B,C
Explanation:
* View the Apex Jobs page and query the AsyncApexJob object are two ways a developer can get the status of an enqueued job for a class that implements the Queueable interface. They are both methods to
* monitor and manage the asynchronous Apex jobs that are submitted to the Apex job queue12.
* View the Apex Jobs page is a user interface option that allows a developer to see the status and results of the asynchronous Apex jobs in the Setup menu of Salesforce. It can show the progress, completion, failure, or cancellation of the jobs, as well as the start time, end time, submitted by, and apex class name of the jobs12.
* Query the AsyncApexJob object is a programmatic option that allows a developer to retrieve the status and results of the asynchronous Apex jobs using SOQL. It can access the same fields and information as the Apex Jobs page, as well as additional fields such as JobType, ParentJobId, and ExtendedStatus12.
* View the Apex Status page and view the Apex Flex Queue are two other options, but they are not applicable for the Queueable interface. They are used for different types of asynchronous Apex jobs12.
* View the Apex Status page is an option that allows a developer to see the status and results of the batch Apex jobs and future methods in the Setup menu of Salesforce. It can show the number of batches or methods processed, failed, or remaining, as well as the start time, end time, submitted by, and apex class or method name of the jobs12.
* View the Apex Flex Queue is an option that allows a developer to see and reorder the pending batch Apex jobs that are waiting to be processed in the Setup menu of Salesforce. It can hold up to 100 batch Apex jobs that exceed the limit of 5 concurrent jobs. It can show the apex class name, submitted by, and submitted date of the jobs12.

NEW QUESTION # 55
A developer is tasked to perform a security review of the ContactSearch Apex class that exists in the system.
Whithin the class, the developer identifies the following method as a security threat: List<Contact> performSearch(String lastName){ return Database.query('Select Id, FirstName, LastName FROM Contact WHERE LastName Like %'+lastName+'%); } What are two ways the developer can update the method to prevent a SOQL injection attack? Choose 2 answers
- A. Use the @Readonly annotation and the with sharing keyword on the class.
- B. Use a regular expression on the parameter to remove special characters.
- C. Use the escapeSingleQuote method to sanitize the parameter before its use.
- D. Use variable binding and replace the dynamic query with a static SOQL.
Answer: C,D
Explanation:
The developer can update the method to prevent a SOQL injection attack by using variable binding and replacing the dynamic query with a static SOQL, or by using the escapeSingleQuote method to sanitize the parameter before its use. These are two ways to avoid concatenating user input directly into the query string, which can allow malicious input to alter the query logic and expose sensitive data. For example, the developer can rewrite the method as follows:
// Using variable binding and static SOQL List<Contact> performSearch(String lastName){ String queryName
= '%' + lastName + '%'; return [SELECT Id, FirstName, LastName FROM Contact WHERE LastName LIKE
:queryName]; }
// Using escapeSingleQuote method List<Contact> performSearch(String lastName){ String sanitizedLastName = String.escapeSingleQuotes(lastName); return Database.query('SELECT Id, FirstName, LastName FROM Contact WHERE LastName LIKE '%' + sanitizedLastName + '%''); } Using a regular expression on the parameter to remove special characters is not a reliable way to prevent a SOQL injection attack, because it may not cover all possible scenarios and may also remove valid input. Using the @Readonly annotation and the with sharing keyword on the class is not relevant to the SOQL injection issue, because they affect the data access and performance of the class, not the security of the query.
