For which three items can a trace flag be configured?
Choose 3 answers
- A. Visualforce
- B. User
- C. Process Builder
- D. Apex Trigger
- E. Apex Class
Answer: A,B,E
Explanation:
A trace flag is a configuration that specifies the debug level, the start time, the end time, and the log type for a user, an Apex class, or an Apex trigger. The log types are DEVELOPER_LOG, USER_DEBUG, and CLASS_TRACING. A trace flag can be configured for Visualforce, Apex classes, and users to enable logging of their activities and events. For example, a trace flag can be set for a Visualforce page to capture the execution time, view state, and heap size. A trace flag can also be set for an Apex class or trigger to override the default logging level and capture more or less information. A trace flag can also be set for a user to monitor their actions and interactions with Salesforce. A trace flag cannot be configured for Process Builder or outbound messages, as they are not supported log types. References:
* TraceFlag from the Tooling API Developer Guide
* Debug Log Levels from the Salesforce Help
* Set Up Debug Logging from the Salesforce Help

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?
- A. Use the with sharing keyword on the class declaration.
- B. Use the without sharing keyword on the class declaration.
- C. Use the UserInfo Apex class to filter all SOQL queries to returned records owned by the logged-in user.
- D. Use the schema describe calls to determine if the logged-in users has access to the Account object.
Answer: A
Explanation:
Use the with sharing keyword on the class declaration. The with sharing keyword ensures that the Apex code respects the object-level, field-level, and record-level sharing settings for the user who is running the Apex code. This means that the code will only return records that the user has access to, according to their Sharing Settings. You can find more information about the with sharing keyword in the official Salesforce documentation (https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_classes_keywords_sharing.htm).
