PDI Exam Dumps - Salesforce Developers Questions and Answers

The correct answer is option B. Use Security.stripInaccessible to remove fields inaccessible to the current user. This method takes a list of records and an access type (READ, UPDATE, CREATE, or UPSERT) and returns a new list of records with the inaccessible fields removed. This way, the Lightning web component can display the records without throwing any errors due to field-level security.

Option A is incorrect because WITH SECURITY_ENFORCED is a SOQL clause that enforces field-level security on all fields in the query. If the query returns any fields that the user does not have access to, the query will throw an exception. This is not desirable for the Lightning web component, as it will prevent the component from displaying any records at all.

Option C is incorrect because Lightning Data Service is a layer of Lightning web components that provides access to Salesforce data and metadata, cache management, and data synchronization. However, Lightning Data Service does not automatically handle field-level security for the records it retrieves. The developer still needs to use Security.stripInaccessible or another method to remove the inaccessible fields.

Option D is incorrect because Lightning Locker Service is a security feature that isolates Lightning web components from each other and from the rest of the page. It does not enforce sharing rules or field-level security for the data that the components access.

Fast field updates record-triggered flow and account trigger are two automation tools that can be used to implement the feature of updating the Timezone field based on the postal code. A fast field update is a type of flow action that can update one or more fields on a record without using any Apex code1. A record-triggered flow can be configured to run when a record is created or updated, and can perform actions such as fast field updates, invocable actions, or subflows2. An account trigger is a piece of Apex code that can execute before or after an account record is inserted, updated, deleted, or undeleted, and can perform complex logic or callouts to external services3. Both of these tools can access the PostalCodeToTimezone_c custom object and update the Timezone field accordingly. References:

 Salesforce CLI is a command-line interface that lets you run commands to create, test, and deploy Salesforce applications. You can easily integrate Salesforce CLI commands into various CI tools, such as CircleCI, Jenkins, or Travis CI, to automate testing and deployment of Salesforce applications against scratch orgs. Salesforce CLI also supports the Salesforce DX development model, which enables source-driven development, team collaboration, and agile delivery. References:

A trace flag is a configuration that specifies the debug level, the start time, the end time, and the log type for a user, an Apex class, or an Apex trigger. The log types are DEVELOPER_LOG, USER_DEBUG, and CLASS_TRACING. A trace flag can be configured for Visualforce, Apex classes, and users to enable logging of their activities and events. For example, a trace flag can be set for a Visualforce page to capture the execution time, view state, and heap size. A trace flag can also be set for an Apex class or trigger to override the default logging level and capture more or less information. A trace flag can also be set for a user to monitor their actions and interactions with Salesforce. A trace flag cannot be configured for Process Builder or outbound messages, as they are not supported log types. References:
