問題 #42
Universal Containers stores user preferences in a Hierarchy Custom Setting, User_Prefs_c, with a Checkbox field, Show_Help_c. Company-level defaults are stored at the organizational level, but may be overridden at the user level. If a user has not overridden preferences, then the defaults should be used.
How should the Show_Help_c preference be retrieved for the current user?
答案：C
解題說明：
To retrieve the Show_Help__c preference for the current user from a hierarchy custom setting, the getInstance() method should be used. This method retrieves the custom setting data for the user or the organization default if no user-specific setting is found.
問題 #43
Universal Containers (UC) has an ERP system that stores customer Information, When an Account is created in Salesforce, the ERP system's REST endpoint for creating new customers must automatically be called with the Account information. If the call to the ERP system falls, the Account should still be created. Accounts in the UC org are only created, one at a time, by users in the UC customer on-boarding department.
What should a developer implement to make the call to the ERP
system's REST endpoint?
答案：B
解題說明：
Since the requirement is to make a callout to an external ERP system when an Account is created and still allow for the Account creation even if the call fails, a Queueable class called from a trigger is the best solution. Queueable Apex allows you to submit jobs for asynchronous processing similar to future methods but with additional benefits such as chaining jobs and monitoring the job status.
By using a Queueable, the callout can be made after the Account is created, which respects the Salesforce order of execution and avoids the limitation of callouts not being allowed after DML operations in the same transaction. This approach also does not block the user interface or the creation of the Account record if the callout to the ERP system takes a long time or fails.

問題 #44
A company has reference data stored in multiple custom metadata records that represent default information and delete behavior for certain geographic regions.
When a contact is inserted, the default information should be set on the contact from the custom metadata records based on the contact's address information.
Additionally, if a user attempts to delete a contact that belongs to a flagged region, the user must get an error message.
Depending on company personnel resources, what are two ways to automate this?
Choose 2 answers
答案：A,B
解題說明：
To automate the process based on the contact's address information and prevent deletion from flagged regions:
Flow Builder: Can be used to set default information on records when they are created.
Apex Trigger: Allows for complex logic to be executed before or after data manipulation operations, including insert and delete. It can be used to enforce rules such as preventing deletion.

問題 #45
A developer wants to write a generic Apex method that will compare the Salesforce Name field between any two object records. For example, to compare the Name field of an Account and an Opportunity; or the Name of an Account and a Contact.
Assuming the Name field exists, how should the developer do this?
答案：A
解題說明：
Casting each object to an sObject and using the get method to compare the Name fields is the correct approach. This is because sObjects are generic object representations that can be used to access the fields of any Salesforce object dynamically. Reference:
sObject Class
問題 #46
When developing a Lightning web component, which setting displays lightninglayout-items im one column on small devices, such as mobile phones, and in two columns on tablet-size and desktop-size screens?
答案：C
解題說明：
To display lightning-layout-items in one column on small devices and in two columns on larger devices, you should set the size attribute to "12" for small devices and the medium-device-size attribute to "6". This ensures that on small devices each item takes the full width, and on medium or larger devices, items take up half the width.
