NEW QUESTION # 116
A developer created a JavaScript library that simplifies the development of repetitive tasks and features and uploaded the library as a static resource called jsutils in Salesforce. Another developer is coding a new Lightning web component (LWC) and wants to leverage the library.
Which statement properly loads the static resource within the LWC?
Answer: C

NEW QUESTION # 118
A developer created a Lightning web component that uses a lightning-record-edit-form to collect information about Leads. Users complain that they only see one error message at a time about their input when trying to save a Lead record. Which best practice should the developer use to perform the validations on more than one field, thus allowing more than one error message to be displayed simultaneously?
Answer: A
Explanation:
When using lightning-record-edit-form, server-side validation rules (Option D) typically return errors one at a time as the database engine encounters them, or as a single combined toast message that can be difficult to parse. To provide a superi1or user experience where multiple fields are validated simultaneously before the data even reaches the server, the develo2per shou3ld implement Client-side validation (Option B).
In the component's JavaScript controller, the developer can intercept the onsubmit event. By iterating through all the lightning-input-field or standard lightning-input elements, the developer can programmatically check for various conditions (e.g., custom regex patterns, conditional logic between fields, or range checks). Each field can then be marked with a custom error message using the reportValidity() or setCustomValidity() methods. This allows the UI to highlight all invalid fields at once, providing immediate, comprehensive feedback to the user. This approach reduces unnecessary server round-trips and ensures that the user can correct all issues in a single pass before successfully submitting the record.
NEW QUESTION # 119
A business currently has a labor-intensive process to manually upload orders from an external OMS.
Accounts must be exported to get IDs to link the orders. Which two recommendations should make this process more efficient?
Answer: A,B
Explanation:
The current bottleneck is caused by the need to resolve Salesforce Internal IDs ($001...$) for the Account lookup before orders can be imported. This can be completely bypassed by using External IDs (Option D) and the Upsert operation (Option C).
* External IDs: By marking a unique field from the OMS (like OMS_Account_Number__c) as an External ID in Salesforce, the developer creates a "foreign key" that Salesforce understands.
* Upsert Wizard: When using the Data Loader's Upsert wizard, the user is asked which field should be used to match the parent Account. By selecting the OMS_Account_Number__c external ID, the Data Loader allows the user to map the orders directly to accounts using the OMS number found in the CSV file.
Salesforce will automatically find the correct Account ID in the background. This eliminates the "export-and- VLOOKUP" step entirely. Option A (Insert) would still require internal IDs. Option B (sorting) helps with performance in massive loads but doesn't solve the manual ID matching problem. Using Upsert with External IDs is the platform-recommended way to streamline recurring data integrations.
NEW QUESTION # 120
Which statement is considered a best practice for writing bulk safe Apex triggers?
Answer: B
Explanation:
Bulk safe Apex triggers are triggers that can handle large batches of records without hitting governor limits, such as the limit of 150 DML statements per transaction. One of the best practices for writing bulk safe Apex triggers is to add records to collections, such as lists or sets, and perform DML operations against these collections, instead of performing DML operations on individual records. This way, the developer can reduce the number of DML statements and optimize the performance of the trigger. For example, the developer can use a list to store the records that need to be updated, and use a single update statement to update the list, instead of using multiple update statements to update each record. Reference: [Bulk Apex Triggers], [DML Operations]
