NEW QUESTION # 28
Which Salesforce feature allows a developer to see when a user last logged in to Salesforce if real-time notification is not required?
Answer: A
Explanation:
Event Monitoring Log provides the ability to track different types of events in Salesforce, including user logins. These logs can be used to determine the last login time of a user without the need for real-time notification.
NEW QUESTION # 29
A developer created an Apex class that updates an Account based on input from a Lightning web component that Is used to register an Account. The update to the Account should only be made if it has not already been registered.
What should the developer do to ensure that users do not overwrite each other's updates to the same Account if they make updates at the same time? A)
B)
C)
D)
Answer: C
Explanation:
When multiple users are updating the same record at the same time, there is a risk of overwriting each other's changes. Salesforce provides a mechanism called 'record locking' to prevent this from happening.
Option D is correct because including FOR UPDATE in the SOQL query locks the retrieved records for the duration of the transaction. This prevents other transactions from updating the record until the current transaction is complete, which is essential for avoiding race conditions where two users might overwrite each other's updates.
Option A is incorrect because while adding a try/catch block around the update operation is good practice for handling exceptions, it does not prevent overwrites from concurrent updates.
Option B is incorrect because using upsert instead of update does not address the problem of concurrent updates. The upsert operation is used to either insert a new record or update an existing one based on whether a record with a matching ID or external ID already exists.
Option C is incorrect because FOR UPDATE should be used in the SOQL query to lock the records, not in the SELECT statement itself.

NEW QUESTION # 30
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?
Answer: B
Explanation:
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
NEW QUESTION # 31
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
Answer: B,D
Explanation:
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.
