質問 # 71
When developing a Lightning web component, which setting displays lightninglayout-items im one column on small devices, such as mobile phones, and in two columns on tablet-size and desktop-size screens?

A. Set size="12" medium-device-size="6"
B. Set size="6" small-device-size="12"
C. Set size="6" mobile-device-size="12"
D. Set size="12" tablet-device-size="6"

正解：A

解説：
To display lightning-layout-items in one column on small devices and in two columns on larger devices, you should set the size attribute to "12" for small devices and the medium-device-size attribute to "6". This ensures that on small devices each item takes the full width, and on medium or larger devices, items take up half the width.

質問 # 75
A developer is working with existing functionality that tracks how many times a stage has changed for an Opportunity. When the Opportunity's stage is changed, a workflow rule is fired to increase the value of a field by one. The developer wrote an after trigger to create a child record when the field changes from 4 to 5.
A user changes the stage of an Opportunity and manually sets the count field to 4. The count field updates to 5, but the child record is not created.
What is the reason this is happening?

A. Trigger.new does not change after a field update.
B. After triggers are not fired after field updates.
C. Trigger.old does not contain the updated value of the count field.
D. After triggers fire before workflow rules.

正解：C

解説：
The reason this is happening is that Trigger.old does not contain the updated value of the count field. Trigger.old is a list of the old versions of the sObject records, before any changes were made in the trigger. Trigger.new is a list of the new versions of the sObject records, after any changes were made in the trigger. In this case, the workflow rule is fired after the trigger, and updates the count field from 4 to 5. However, the trigger does not see this change, as it only compares the values in Trigger.old and Trigger.new, which are both 4. To fix this, the developer should use an after update trigger, and re-query the updated records to get the latest values of the count field. After triggers fire before workflow rules is incorrect, as workflow rules fire after triggers. Trigger.new does not change after a field update is incorrect, as Trigger.new does change after a field update, but only within the same trigger context. After triggers are not fired after field updates is incorrect, as after triggers are fired after field updates, unless the field updates are made by a workflow rule or a process.
