Northern Trail Outfitters (NTO) exports Order Summary data from its org. A developer launches Data Loader, selects Order Summary, clicks the Select All Fields button, and clicks Finish. Custom fields are defined in the Cart and Order Summary objects and successfully mapped from Cart to Order Summary during checkout. However, all three custom fields in the Order Summary are empty in the export file.

Question #4

Which two are considered discrete units of work (code units) within a transaction in the debug logs?

Reveal Solution Hide Solution
Correct Answer: C, D

Two data types that are considered discrete units of work (code units) within a transaction in the debug logs are web service invocation and Apex class. A discrete unit of work (code unit) is a segment of executable code that runs as part of a transaction in Salesforce. A transaction is a sequence of operations that are treated as a single unit of work and are executed under certain isolation and consistency rules. A transaction can consist of one or more discrete units of work (code units) that are executed sequentially or concurrently depending on various factors such as triggers, asynchronous calls, or limits. A debug log is a record of database operations, system processes, and errors that occur when executing a transaction or running unit tests in Salesforce. A debug log can capture information about each discrete unit of work (code unit) within a transaction, such as its start time, end time, duration, events, variables, and limits. A web service invocation is a type of discrete unit of work (code unit) that involves calling an external web service from Apex code using SOAP or REST protocols. A web service invocation can be synchronous or asynchronous depending on the method used to make the callout. A web service invocation can be captured in a debug log with its details and results. An Apex class is another type of discrete unit of work (code unit) that involves executing Apex code that defines a class with properties and methods. An Apex class can be invoked from various sources such as triggers, Visualforce pages, Lightning components, or API calls. An Apex class can be captured in a debug log with its details and results. A validation rule is not a type of discrete unit of work (code unit) within a transaction in the debug logs, as it is not a segment of executable code but rather a formula expression that defines a business rule for a field or object. A validation rule can be evaluated during a transaction and cause an error if the rule condition is not met, but it cannot be captured as a separate code unit in a debug log. A Lightning component load is not a type of discrete unit of work (code unit) within a transaction in the debug logs either, as it is not a segment of executable code but rather an event that occurs when a Lightning component is rendered on a web page or application. A Lightning component load can be measured by various performance tools such as Lightning Inspector or Lighthouse, but it cannot be captured as a separate code unit in a debug log.

Question #5

A developer attempts to export data from an org by launching Data Loader, selecting a standard entity, clicking the "Select All Fields" button and clicking the Finish button. The developer finds that the CustomField_c field they added to the entity has no values under the header in the CSV file output. What is the root cause?

Reveal Solution Hide Solution
Correct Answer: D

The root cause of why the CustomField__c field they added to the entity has no values under the header in the CSV file output is that the user does not have rights to the custom field. A user's access to a field is determined by their profile and permission sets, which define their field-level security settings. Field-level security settings control whether a user can see, edit, or delete the value for a particular field on an object. If a user does not have access to a field, they will not be able to view or modify its value in any interface, including Data Loader. Data Loader is a tool that allows users to import or export data between Salesforce and CSV files. When using Data Loader to export data from an org, Data Loader will only include fields that are accessible to the user based on their field-level security settings. If a user does not have access to a field, Data Loader will not include that field in the CSV file, neither as a column header nor as a value. The developer does not have the correct JDK that is recommended by Salesforce and this is known to cause issues with exporting custom attributes is not the root cause of why CustomField__c has no values under the header in the CSV file output, as it is not related to field access or Data Loader functionality. The developer does not have access to the object's metadata is not the root cause either, as it is not related to field access or Data Loader functionality. The object's metadata defines its structure and properties, such as fields, relationships, and layouts. The field is not populated is not the root cause either, as it contradicts the fact that CustomField__c has no column header in the CSV file output. If the field was not populated but accessible to the user, Data Loader would still include CustomField__c as a column header in the CSV file, but leave its values blank.
