NEW QUESTION # 171
A company has a web page that needs to get Account record information, such as name, website, and employee number. The Salesforce record 1D is known to the web page and it uses JavaScript to retrieve the account information.
Which method of integration is optimal?
Answer: C
Explanation:
For retrieving specific records using a known ID, the REST API is optimal due to its stateless, cacheable communications and lightweight structure. It's ideal for web applications that use JavaScript to make requests directly from the user's browser. Using the REST API, the web page can make a simple HTTP GET request to the Salesforce REST service endpoint and retrieve the account information in a format that's easily handled by JavaScript (typically JSON).

NEW QUESTION # 172
A developer built an Aura component for guests to self-register upon arrival at a front desk kiosk. Now the developer needs to create a component for the utility tray to alert users whenever a guest arrives at the front desk.
What should be used?
Answer: D
Explanation:
Application Events in Aura components are used for communication between components that are not in the same containment hierarchy. An application event to alert users about the arrival of a guest at the front desk is appropriate because it allows any component within the app to listen and respond to the event, regardless of where it is located in the component hierarchy.
NEW QUESTION # 173
Refer to the code snippet below:
A custom object called Credit_Memo__c exists in a Salesforce environment. As part of a new feature development that retrieves and manipulates this type of record, the developer needs to ensure race conditions are prevented when a set of records are modified within an Apex transaction. In the preceding Apex code, how can the developer alter the query statement to use SOQL features to prevent race conditions within a transaction? A)
B)
C)
D)
Answer: D
Explanation:
To prevent race conditions during an Apex transaction, the SOQL query can be modified to include the "FOR UPDATE" keyword. This keyword locks the records that are returned by the query, preventing other transactions from modifying them until the current transaction is complete. This ensures that the retrieved records cannot be changed by another process before the current transaction is completed, thus preventing race conditions. The correct option to use in the code snippet provided is:
[SELECT Id, Name, Amount__c FROM Credit_Memo__c WHERE Customer_Id__c = :customerId LIMIT 50 FOR UPDATE] This will lock up to 50 records of Credit_Memo__c with the specified Customer_Id__c for the duration of the transaction.
FOR UPDATE

NEW QUESTION # 174
Universal Containers (UC) has enabled the translation workbench and has translated picklist values. UC has a custom multi-select picklist field, Product__c, on the Account object that allows sales reps to specify which of UC's products an Account already has. A developer is tasked with writing an Apex method that retrieves Account records, including the Product_c field.
What should the developer do to ensure the value of Products__c is in the current user's language?
Answer: B
Explanation:
Using toLabel() in the SOQL query ensures that picklist values are returned in the user's language, which is necessary for organizations that have the translation workbench enabled.
