NEW QUESTION # 67
A developer needs a Lightning web component to display in one column on phones and two columns on tablets/desktops. Which should the developer add to the code?
Answer: C
Explanation:
Comprehensive and Detailed Explanation:
The lightning-layout grid system uses a 12-column model. To achieve a responsive design, developers use attributes that target different screen breakpoints.
* size: Defines the default size (usually targeting the smallest devices if no other attributes are present).
* medium-device-size: Targets tablets and small desktops.
* large-device-size: Targets large monitors.
To show one column on a phone, an item must occupy all 12 columns (size="12"). To show two columns on a tablet/desktop, each item must occupy 6 columns (medium-device-size="6").
Option A correctly implements this. While small-device-size exists, the size attribute itself typically serves as the baseline for small devices. If you set size="12" and medium-device-size="6", the component will "stack" on phones and sit side-by-side on anything larger.
NEW QUESTION # 68
Universal Containers (UC) has an ERP system that stores customer Information, When an Account is created in Salesforce, the ERP system's REST endpoint for creating new customers must automatically be called with the Account information. If the call to the ERP system falls, the Account should still be created. Accounts in the UC org are only created, one at a time, by users in the UC customer on-boarding department.
What should a developer implement to make the call to the ERP
system's REST endpoint?
Answer: C
Explanation:
Since the requirement is to make a callout to an external ERP system when an Account is created and still allow for the Account creation even if the call fails, a Queueable class called from a trigger is the best solution.
Queueable Apex allows you to submit jobs for asynchronous processing similar to future methods but with additional benefits such as chaining jobs and monitoring the job status.
By using a Queueable, the callout can be made after the Account is created, which respects the Salesforce order of execution and avoids the limitation of callouts not being allowed after DML operations in the same transaction. This approach also does not block the user interface or the creation of the Account record if the callout to the ERP system takes a long time or fails.
