Salesforce Certified Platform Developer I Sample Questions (Q74-Q79):
NEW QUESTION # 74
Which three Salesforce resources can be accessed from a Lightning web component?
Choose 3 answers
Answer: A,C,E
Explanation:
Lightning Web Components (LWC) can access various Salesforce resources.
Option B: SVG resources
Accessible.
LWCs can include SVG files to define custom icons for the component.
The SVG file is placed in the component bundle with the name componentName.svg.
LWCs can access content asset files using the @salesforce/contentAssetUrl import.
This allows components to reference content assets stored in Salesforce.
Example:
import myContentAsset from '@salesforce/contentAssetUrl/My_Asset';
LWCs can access static resources using the @salesforce/resourceUrl import.
Static resources can include JavaScript libraries, images, stylesheets, etc.
Example:
import myResource from '@salesforce/resourceUrl/My_Resource';
LWCs can use external JavaScript libraries, but there are restrictions.
The library must be included as a static resource and must be compatible with Locker Service.
Not all external libraries can be used due to security restrictions.
LWCs cannot import or use third-party web components due to Locker Service and namespace restrictions.
Components must be within the same namespace to be used.
Conclusion:
The three Salesforce resources that can be accessed from a Lightning web component are:
Option B: SVG resources
Option D: Content asset files
Option E: Static resources
Reference:

NEW QUESTION # 75
In the following example, which sharing context will myMethod execute when it is invoked?
Answer: D
Explanation:
In the provided class:
public class myClass {
public void myMethod() { /* implementation */ }
}
The class myClass is declared without any sharing keyword (with sharing, without sharing, or inherited sharing).
Default Sharing Behavior:
Apex classes without an explicit sharing declaration run in system context, meaning they do not enforce sharing rules.
Option B: Sharing rules will not be enforced for the running user.
Reference:
"If a class is not declared as either with sharing or without sharing, the class does not enforce sharing rules except when it acquires sharing rules from another class."
- Apex Developer Guide: Using the with sharing or without sharing Keywords Why Other Options Are Incorrect:
Option A: Sharing rules are not inherited from the calling context unless inherited sharing is used.
Option C: There is no instantiating class that enforces sharing in this context.
Option D: Sharing rules are not enforced unless with sharing is specified.
NEW QUESTION # 76
What Is the result of the following code?
Answer: C
NEW QUESTION # 77
Universal Containers implemented a private sharing model for the Account object. A custom Account search tool was developed with Apex to help sales representatives find accounts that match multiple criteria they specify. Since its release, users of the tool report they can see Accounts they do not own. What should the developer use to enforce sharing permission for the currently logged-in user while using the custom search tool?
Answer: D
Explanation:
The with sharing keyword on the class declaration enforces the sharing rules that apply to the current user.
This means that the user can only see and modify the records that they have access to based on the organization-wide defaults, role hierarchy, sharing rules, manual sharing, teams, and territories. The without sharing keyword, on the other hand, ignores the sharing rules and allows the user to access all records, regardless of ownership or sharing settings. This can pose a security risk and should be used with caution.
The schema describe calls and the UserInfo Apex class do not directly affect the sharing rules, but rather provide information about the object and field permissions, and the user's profile and role, respectively. These can be used to check the user's access level, but not to enforce the sharing rules on the custom search tool. References:
