질문 # 181
An Aura component has a section that displays some information about an Account and it works well on the desktop, but users have to scroll horizontally to see the description field output on their mobile devices and tablets.
How should a developer change the component to be responsive for mobile and tablet devices? A)
B)
C)
D)
정답：B
설명：
To make the Aura component responsive, the developer should set multipleRows="true" to allow the layout items to wrap onto multiple rows on smaller devices. Additionally, setting the size attribute for different device sizes ensures that the layout adapts to the screen width.
질문 # 182
A developer has a requirement to query three fields (Id, Name, Type) from an Account; and first and last names for all Contacts associated with the Account.
Which option is the preferred, optimized method to achieve this for the Account named 'Ozone Electronics'?
A)
B)
C)
D)
정답：A
질문 # 183
An environment has two Apex triggers: an after-update trigger on Account and an after-update trigger on Contact.
The Account after-update trigger fires whenever an Account's address is updated, and it updates every associated Contact with that address. The Contact after-update trigger fires on every edit, and it updates every Campaign Member record related to the Contact with the Contact's state.
Consider the following: A mass update of 200 Account records' addresses, where each Account has 50 Contacts. Each Contact has one Campaign Member. This means there are 10,000 Contact records across the Accounts and 10,000 Campaign Member records across the contacts.
What will happen when the mass update occurs?
정답：D
설명：
In this scenario, the governor limit for DML statements (150 DML operations and 10,000 DML rows per transaction) will be exceeded because the updates will cascade across related objects, significantly multiplying the number of records processed.

질문 # 184
A developer is asked to modify a Lightning web component so that it displays in one column on phones and in two columns on tablets, desktops, and larger devices.
Given to the code below:
Which should the developer add to the code to meet the requirements? A)
B)
C)
D)
정답：A
설명：
The requirement is for the Lightning web component to display in one column on phones and in two columns on larger devices. To achieve this, we should specify the size attributes for different devices using the design tokens provided by the Lightning Design System.
Option B is correct because size="6" will set each lightning-layout-item to take up half the available space (since the grid system is based on a 12-column structure), creating two columns on tablets, desktops, and larger devices. small-device-size="12" will ensure that on small devices like phones, each item will take up the full width, resulting in a single column.
Options A, C, and D do not meet the requirement correctly, as they either do not set the size correctly for small devices or do not specify the sizes for both small and larger devices appropriately.

질문 # 185
A Salesforce org has more than 50,000 contacts. A new business process requires a calculation that aggregates data from all of these contact records. This calculation needs to run once a day after business hours.
which two steps should a developer take to accomplish this?
Choose 2 answers
A)
B)
C)
D)
정답：A,B
설명：
When dealing with large datasets and the need to perform complex calculations or data aggregation, batch Apex and scheduling are typically used to efficiently process records in batches and to execute the process during off-peak hours.
Option B is correct because using the @future annotation allows you to run methods in the background, but it is not suitable for operations that need to process more than 50,000 records, which is the governor limit for future methods.
Option C is correct because implementing the Schedulable interface allows you to schedule the class to run at specified times, such as after business hours, which is a requirement for this scenario.
Option A is incorrect because Queueable is typically used for chaining jobs and handling asynchronous processing of individual transactions, not for processing large datasets at scheduled times.
Option D is incorrect because the Database.Batchable interface is what's needed for processing large datasets, not Database.Stateful. The Database.Stateful interface is used to maintain state across batch job transactions.
