NEW QUESTION # 122
Universal Containers (UC) wants to lower its shipping cost while making the shipping process more efficient. The Distribution Officer advises UC to implement global addresses to allow multiple Accounts to share a default pickup address. The developer is tasked to create the supporting object and relationship for this business requirement and uses the Setup Menu to create a custom object called "Global Address".
Which field should the developer add to create the most efficient model that supports the business need?
Answer: C
Explanation:
Scenario:
Universal Containers (UC) wants to allow multiple Accounts to share a default pickup address.
They have created a custom object called Global Address.
Requirement:
Create an efficient model to link multiple Accounts to a single Global Address.
Solution:
To associate multiple Accounts with a single Global Address, we need to create a lookup relationship from Account to Global Address.
Option D: Add a lookup field on the Account object to the Global Address object.
Correct Approach.
Adding a Lookup Field on the Account object that references the Global Address object allows multiple Accounts to reference the same Global Address.
This setup models a many-to-one relationship:
Many Accounts can have the same Global Address as their pickup address.
Benefits:
Data Normalization: Reduces data redundancy by storing the address once.
Ease of Maintenance: Updating the Global Address updates it for all associated Accounts.
An object cannot have two master-detail relationships to the same object.
Master-detail relationships imply ownership and cascade deletion, which may not be appropriate.
Does not address the requirement efficiently.
Option B: Add a master-detail field on the Global Address object to the Account object.
Incorrect Relationship Direction.
This would imply that each Global Address is owned by a single Account.
Does not allow multiple Accounts to share the same Global Address.
The master-detail relationship would be from Global Address to Account, which is opposite of what's needed.
Option C: Add a lookup field on the Global Address object to the Account object.
Incorrect Relationship Direction.
This creates a relationship where each Global Address references a single Account.
Does not support multiple Accounts sharing the same Global Address.
Would create a one-to-one relationship.
Conclusion:
Adding a Lookup Field on the Account object pointing to the Global Address object (Option D) creates a many-to-one relationship.
This efficiently models the business need where multiple Accounts can share a default pickup address.
Reference:
Lookup Relationships
Creating Relationships Among Objects
Why Other Options are Not Suitable:
Option A: Add 2 master-detail fields on the Account object to the Global Address object.
Incorrect.
NEW QUESTION # 123
Universal Containers has developed custom Apex code and Lightning Components in a Sandbox environment. They need to deploy the code and associated configurations to the Production environment.
What is the recommended process for deploying the code and configurations to Production?
Answer: B
Explanation:
The recommended process for deploying code and configurations from a Sandbox to Production is to use a change set.
Option C: Use a change set to deploy the Apex code and Lightning Components.
Reference:
"Change sets contain information about the org customizations you want to deploy and the org to which you want to deploy them."
- Salesforce Help: Change Sets
Why Other Options Are Less Preferred:
Option A: The Force.com IDE has been retired and is no longer the recommended tool.
Option B: The Ant Migration Tool is useful but requires more setup and is typically used for complex deployments or CI/CD processes.
Option D: Salesforce CLI is powerful but may not be necessary for straightforward deployments between connected orgs.
NEW QUESTION # 124
A developer must provide a custom user interface when users edit a Contact. Users must be able to use the interface in Salesforce Classic and Lightning Experience.
What should the developer do to provide the custom user interface?
Answer: B
NEW QUESTION # 125
Which two actions may cause triggers to fire?
Choose 2 answers
Answer: A,C
Explanation:
In Salesforce, triggers are executed in response to specific database events on standard objects (such as Account or Contact) and custom objects. The following actions can cause triggers to fire:
Option A: Cascading delete operations
Reference:
"Deleting a parent record in a master-detail relationship deletes all the detail records. This deletion can fire any triggers on those detail records."
- Salesforce Developer Guide: Triggers and Order of Execution
Option C: Updates to FeedItem
"You can write triggers for certain standard objects, including FeedItem."
- Salesforce Developer Guide: Triggers
Why Other Options Are Incorrect:
Option B: Changing a user's default division does not fire triggers because it does not perform DML operations on records that would invoke triggers.
Option D: Renaming or replacing a picklist entry changes metadata and does not perform DML operations on records, so triggers are not fired.
