NEW QUESTION # 154
When using SalesforceDX, what does a developer need to enable to create and manage scratch orgs?

A. Environment Hub
B. Dev Hub
C. Sandbox
D. Production

Answer: B

Explanation:
https://developer.salesforce.com/docs/atlas.en-us.sfdx_dev.meta/sfdx_dev/sfdx_dev_scratch_orgs.htm When using SalesforceDX, a developer needs to enable Dev Hub in order to create and manage scratch orgs. A Dev Hub is a special type of org used by developers to store source code and other development-related artifacts. It is also used to create and manage scratch orgs, which are temporary orgs used for development and testing.

NEW QUESTION # 155

When the code executes, a DML exception is thrown.
How should a developer modify the code to ensure exceptions are handled gracefully?

A. Remove null items from the list of Accounts.
B. Implement Change Data Capture.
C. Implement a try/catch block for the DML.
D. Implement the upset DML statement.

Answer: C

Explanation:
* Why a try/catch block is required:
* In Salesforce, DML operations such as insert, update, delete, and upsert can throw exceptions due to issues like validation rule violations, field constraints, or sharing rule restrictions.
* Using a try/catch block ensures that these exceptions are caught and handled gracefully, preventing the entire transaction from failing.
* How to modify the code:
* The update statement in the code can be wrapped in a try/catch block to catch and handle any exceptions that occur. For example:
apex
Copy code
public static void insertAccounts(List<Account> theseAccounts) {
try {
for (Account thisAccount : theseAccounts) {
if (thisAccount.website == null) {
thisAccount.website = 'https://www.demo.com';
}
}
update theseAccounts;
} catch (DmlException e) {
System.debug('DML Exception: ' + e.getMessage());
}
}
* Why not the other options?
* A. Implement the upsert DML statement:
* upsert is used to either insert or update records based on an external ID or primary key. It does not inherently handle exceptions.
* B. Implement Change Data Capture:
* Change Data Capture (CDC) is used for tracking changes to data in real time and is unrelated to handling DML exceptions.
* D. Remove null items from the list of Accounts:
* While cleaning the input data is a good practice, it does not address the need for exception handling during DML operations.
References:
* Apex Error Handling
* DML Operations in Apex
