NEW QUESTION # 110
A Developer Edition org has five existing accounts. A developer wants to add 10 more accounts for testing purposes.
The following code is executed in the Developer Console using the Execute Anonymous window:
How many total accounts will be in the org after this code is executed?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: D

Explanation:
The code snippet in question creates and inserts an account namedMyAccountand then initializes a loop to add additional accounts.
The loop runs fromx = 1and continues adding accounts untilx < 10.
Since the conditionx++is post-increment, the loop runs exactly 10 times, creating and adding 10 new accounts to thenewAccountslist.
At the end, theinsertDML statement persists these 10 new accounts, along with the already existing account (MyAccount).
Total accounts in the org:
Existing accounts = 5
New accounts added = 10
Total = 15

• B. Decrease the batch size to reduce the load on the system.
• C. Check the asynchronous job monitoring page to view the job status and logs.
• D. Check the debug logs for the batch job.

Answer: C

Explanation:
When troubleshooting batch Apex jobs:
Asynchronous Job Monitoring:
Navigate toSetup > Apex Jobsto view the status of the batch job.
Provides information such as success, errors, and total execution time.
This step is crucial to diagnose whether the issue is with system limits, batch size, or specific records.
Debug Logs:
After identifying the issue in the job monitoring page, use debug logs to pinpoint specific errors or bottlenecks.
B: Check the debug logs for the batch job: Debug logs are a secondary step after checking the job status.
C: Disable and recreate with fewer records: Premature without investigating the root cause.
D: Decrease the batch size: Adjusting batch size is a solution but only after identifying the cause of the timeout.

NEW QUESTION # 115
A developer created a Visualforce page and custom controller to display the account type field as shown below.
Custom controller code:

Visualforce page snippet:

The value of the account type field is not being displayed correctly on the page. Assuming the custom controller is properly referenced on the Visualforce page, what should the developer do to correct the problem?

• A. Add a getter method for the actType attribute.
• B. Change theAccount attribute to public.
• C. Add with sharing to the custom controller.
• D. Convert theAcccunt, type to a String.

Answer: A

Explanation:
The issue is that the value of the account type field is not being displayed correctly on the Visualforce page.
This can be resolved by adding a getter method for the actType attribute in the custom controller. A getter method is used to retrieve the value of a private variable, ensuring that it's read-only and cannot be modified by external classes or pages, thus maintaining encapsulation and security. References: The need for getter methods and their usage can be referenced in Apex basics where encapsulation, getters, and setters are discussed: Apex Basics & Database

• C. Use the Data Loader command line.
• D. Define a Data Export scheduled job.

Answer: D

Explanation:

NEW QUESTION # 118
Universal Containers (UC) uses a custom object called Vendor. The Vendor custom object has a master-detail relationship with the standard Account object.
Based on some internal discussions, the UC administrator tried to change the master-detail relationship to a lookup relationship, but was not able to do so.
What is a possible reason that this change was not permitted?

• A. The Account object does not allow changing a field type for a custom field.
• B. The Account object has a roll up summary field on the Vendor object.
• C. The organization wide default for the Vendor object is Public Read/Write.
• D. Some of the Vendor records have null for the Account field.

Answer: B

Explanation:
Master-detail relationships allow roll-up summary fields to aggregate data from child records. If a roll-up summary field exists on the Account object, the relationship cannot be changed to a lookup because lookup relationships do not support roll-up fields.
Why not other options?
A: Null values in the Vendor records do not prevent the change.
C: Custom fields can have their types changed as long as dependencies like roll-up fields are not present.
D: Organization-wide defaults do not affect the ability to change relationships.

NEW QUESTION # 123
Universal Containers has an order system that uses an Order Number to identify an order for customers and service agents. Order records will be imported into Salesforce.
How should the Order Number field be defined in Salesforce?

• A. External ID and Unique
• B. Direct Lookup
• C. Lookup
• D. Indirect Lookup

Answer: A

Explanation:
The Order Number field should be defined as an External ID and Unique field in Salesforce. This is because the Order Number is a unique identifier that comes from an external system and needs to be matched with the corresponding order records in Salesforce. An External ID field allows you to use the Order Number as a foreign key for data integration and upsert operations. A Unique field ensures that no two order records have the same Order Number in Salesforce. References:

NEW QUESTION # 130
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. Use the order number from the OMS as an external ID.
• B. Write a before trigger on the order object to delete any duplicates.
• C. Ensure that the order number in the OMS is unique.
• D. Use the email on the contact record as an external ID.

Answer: A,C

Explanation:
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.
