質問 # 103
Managers at Universal Containers want to ensure that only decommissioned containers are able to be deleted in the system. To meet the business requirement a Salesforce developer adds "Decommissioned" as a picklist value for the Status _c custom field within the Container _c object.
Which two approaches could a developer use to enforce only Container records with a status of
"Decommissioned" can be deleted?
Choose 2 answers

A. After record-triggered flow
B. Validation rule
C. Before record-triggered flaw
D. Apex trigger

正解：B、D

解説：
Apex Trigger (Option B):
An Apex trigger can be written on theContainer__cobject to prevent deletion unless theStatus__cfield value is
"Decommissioned".
This allows custom logic to be executed during the deletion process.
Apex Triggers Documentation
Validation Rule (Option D):
A validation rule is typically used to enforce conditions during record creation or update. However, it cannot directly restrict deletions.
To ensure deletion restriction, an Apex trigger is more effective.
Not Suitable:
Option A(Before record-triggered flow): Flows triggered "before delete" are not available.
Option C(After record-triggered flow): These occur after a record is deleted, so they cannot prevent the deletion process.

質問 # 108
A business has a proprietary Order Management System (OMS) that creates orders from their website and fulfills the orders. When the order is created in the OMS, an integration also creates an order record in Salesforce and relates it to the contact as identified by the email on the order. As the order goes through different stages in the OMS, the integration also updates It in Salesforce. It is noticed that each update from the OMS creates a new order record in Salesforce.
Which two actions will prevent the duplicate order records from being created in Salesforce?
Choose 2 answers

A. Write a before trigger on the order object to delete any duplicates.
B. Ensure that the order number in the OMS is unique.
C. Use the email on the contact record as an external ID.
D. Use the order number from the OMS as an external ID.

正解：B、D

解説：
The problem of duplicate order records is caused by the integration not being able to identify the existing order record in Salesforce and creating a new one instead. To prevent this, the integration needs to use a unique identifier that can match the order record in both systems. The order number in the OMS can serve as such an identifier, if it is guaranteed to be unique and not reused. Therefore, the following actions can prevent the duplicate order records from being created in Salesforce:
* Option A: Ensure that the order number in the OMS is unique. This will ensure that there is no ambiguity or confusion when matching the order records in both systems.
* Option B: Use the order number from the OMS as an external ID. An external ID is a custom field that can be used to store a unique identifier from an external system. By using the order number from the OMS as an external ID, the integration can use the upsert operation to either insert a new order record or update an existing one based on the external ID value.

質問 # 110
What are three characteristics of change set deployments?
Choose 3 answers Sending a change set between two orgs requires a deployment connection.

A. Sending a change set between two orgs requires a deployment connection.
B. Change sets can deploy custom settings data.
C. Change sets can only be used between related organizations.
D. Change sets can be used to transfer records.
E. Deployment is done in a one-way, single transaction.

正解：A、C、E

解説：
Change sets can only be used between related organizations:
Change sets require a relationship between the source and target Salesforce orgs, such as a production org and its sandboxes. You cannot use change sets between unrelated Salesforce orgs.
Reference:Salesforce Change Set Overview
Deployment is done in a one-way, single transaction:
When a change set is deployed, it is applied to the target org as a single transaction. If there are any errors in the deployment, the entire transaction is rolled back.
Reference:Apex Development Guide
Sending a change set between two orgs requires a deployment connection:
Before sending or deploying a change set, a deployment connection must be established between the source and target orgs. This connection is configured in the setup menu under "Deployment Connections." Reference:Trailhead: Deployment Connections Incorrect Options:
A: Change sets can deploy custom settings data:
Change sets cannot deploy data, including custom settings data. They only move metadata.
E: Change sets can be used to transfer records:
Records (data) are not supported by change sets; they only facilitate metadata migration.

質問 # 112
A developer created a trigger on a custom object. This custom object also has some dependent pick lists.
According to the order of execution rules, which step happens first?

A. System validation is run for maximum field lengths.
B. JavaScript validation is run In the browser.
C. Old values are overwritten with the new record values,
D. The original record is loaded from the database.

正解：B

解説：
According to the order of execution rules, the first step that happens when a record is saved is the JavaScript validation on the browser, if the record contains any dependent picklist fields. This validation limits each dependent picklist field to its available values. No other validation occurs on the client side. The other steps happen later on the server side, after the record is submitted to the server. References:

質問 # 114
Which statement generates a list of Leads and Contacts that have a field with the phrase 'ACME'?

A. List<List <sObject>> searchList = [FIND '*ACME*" IN ALL FIELDS RETURNING Contact, Lead];
B. List <sObject> searchList = [FIND '*ACME*' IN ALL FIELDS RETURNING Contact, Lead];
C. List<List <sObject>> searchList = [SELECT Name, ID FROM Contact, Lead WHERE Name like
"tACME3"];
D. Map <sObject> searchList = [FIND '*ACME*' IN ALL FIELDS RETURNING Contact, Lead];

正解：B

解説：
The correct statement is D, because it uses the SOSL syntax to search for the phrase 'ACME' in all fields of the Contact and Lead objects, and returns a list of sObjects that match the criteria. The other statements are incorrect because:
* A uses the SOQL syntax, which can only query one object at a time, and the LIKE operator requires a wildcard character (%) before and after the search term.
* B uses the SOSL syntax, but returns a list of lists of sObjects, which is not the expected output.
* C uses the SOSL syntax, but returns a map of sObjects, which is not the expected output. References:

質問 # 119
A software company is using Salesforce to track the companies they sell their software to in the Account object. They also use Salesforce to track bugs in their software with a custom object, Bug__c.
As part of a process improvement initiative, they want to be able to report on which companies have reported which bugs. Each company should be able to report multiple bugs and bugs can also be reported by multiple companies.
What is needed to allow this reporting?

A. Roll-up summary field of Bug_c on Account
B. Lookup field on Bug_c to Account
C. Function object between Bug__c and Account
D. Master-detail field on Bug_c to Account

正解：C

解説：
Many-to-Many Relationship:
To track which companies (Accounts) report which bugs and allow multiple associations for both, ajunction objectis needed.
This junction object will have two master-detail relationships: one toBug__cand one toAccount.
Why Not Other Options?
A: Roll-up summary field: Not suitable for many-to-many relationships.
B: Master-detail field on Bug__c to Account: Creates a one-to-many relationship, not many-to-many.
C: Lookup field on Bug__c to Account: Still creates a one-to-many relationship, not many-to-many.

質問 # 120
A developer identifies the following triggers on the Expense _c object:

The triggers process before delete, before insert, and before update events respectively.
Which two techniques should the developer implement to ensure trigger best practices are followed?
Choose 2 answers

A. Unify the before insert and before update triggers and use Flow for the delete action.
B. Create helper classes to execute the appropriate logic when a record is saved.
C. Unity all three triggers In a single trigger on the Expense__c object that Includes all events.
D. Maintain all three triggers on the Expense __c object, but move the Apex logic out of the trigger definition.

正解：B、C

解説：
A: Unify all three triggers in a single trigger on the Expense__c object that includes all events:
Salesforce best practices recommend having only one trigger per object to avoid redundancy and conflicts.
By combining all the events (before delete, before insert, and before update) into a single trigger, the developer can manage the logic in an organized and maintainable manner.
This also simplifies debugging and ensures that the trigger logic executes in a predictable order.
C: Create helper classes to execute the appropriate logic when a record is saved:
Using helper classes allows for a clean separation of concerns. The trigger becomes a dispatcher that delegates logic to dedicated classes.
For example, you can create methods like applyDefaultsToExpense(), validateExpenseUpdate(), and deleteExpense() in a helper class and invoke them from the trigger.
This improves reusability, readability, and testability of the code.
Why not the other options?
B: Unify the before insert and before update triggers and use Flow for the delete action:
While Flow is a powerful tool, it is not ideal for deleting records or replacing Apex trigger functionality, especially when triggers already exist for other events.
D: Maintain all three triggers on the Expense__c object but move the Apex logic out of the trigger definition:
Maintaining multiple triggers on the same object can lead to conflicts and execution order issues, even if the logic is moved to helper classes.
