NEW QUESTION # 163
The following automations already exist on the Account object;
* A workflow rule that updates a field when a certain criteria is met
* A custom validation on a field
* A How that updates related contact records
A developer created a trigger on the Account object.
What should the developer consider while testing the trigger code?
Answer: B
Explanation:
A trigger may fire multiple times during a transaction because of the order of execution of different automation tools in Salesforce. According to the documentation, the order of execution is as follows:
* Executes all before triggers.
* Saves the record to the database, but doesn't commit yet.
* Executes all after triggers.
* Executes assignment rules.
* Executes auto-response rules.
* Executes workflow rules.
* If there are workflow field updates, updates the record again.
* If the record was updated with workflow field updates, fires before update triggers and after update triggers one more time (and only one more time), in addition to standard validations. Custom validation rules, duplicate rules, and escalation rules are not run again.
* Executes processes and flows launched via processes and flow trigger workflow actions. When a process or flow executes a DML operation, the affected record goes through the save procedure.
* Executes escalation rules.
* Executes entitlement rules.
* If the record contains a roll-up summary field or is part of a cross-object workflow, performs calculations and updates the roll-up summary field in the parent record. Parent record goes through save procedure.
* If the parent record is updated, and a grandparent record contains a roll-up summary field or is part of a cross-object workflow, performs calculations and updates the roll-up summary field in the grandparent record. Grandparent record goes through save procedure.
* Executes Criteria Based Sharing evaluation.
* Commits all DML operations to the database.
* Executes post-commit logic, such as sending email.
As you can see, there are several steps that can cause the record to go through the save procedure again, which will fire the triggers again. Therefore, the developer should consider this possibility and write the trigger code accordingly to avoid unwanted side effects or recursion. For example, the developer can use static variables to track the trigger invocation or use bulkified patterns to handle collections of records efficiently.

NEW QUESTION # 164
which statement is true regarding execution order when triggers are associated to the same object and event?
Answer: C
Explanation:
When multiple triggers are associated to the same object and event, such as before insert or after update, the trigger execution order cannot be guaranteed by Salesforce1. This means that the triggers may run in any order, and the order may change from one execution to another. Therefore, it is not advisable to rely on the order of execution of triggers, or to assume that the order is based on the trigger name, creation date, or modification date. Instead, it is recommended to use a single trigger per object and event, and use helper classes or methods to handle the logic for different scenarios2. References:

NEW QUESTION # 165
Which scenario is valid for execution by unit tests?
Answer: B

A: Unit tests cannot execute anonymous Apex as a different user.
C: Unit tests cannot perform callouts unless mock responses are provided.
D: TheSystem.createdDatefield cannot be set manually in unit tests.

NEW QUESTION # 166
Which two events need to happen when deploying to a production org? Choose 2 answers
Answer: B,D
NEW QUESTION # 167
What should a developer do to check the code coverage of a class after running all tests?
Answer: D
Explanation:
To check the code coverage of a class after running all tests, the developer should view the code coverage percentage for the class using the Overall Code Coverage panel in the Developer Console Tests tab. This panel shows the code coverage for each class and trigger in the org, as well as the overall code coverage percentage.
The developer can also double-click on a class or trigger name to see the code coverage details, such as which lines are covered or not covered by tests.
The other options are not correct because:
* A. View the Code Coverage column in the list view on the Apex Classes page. This option only shows the code coverage percentage for each class, but not the details of which lines are covered or not covered by tests. It also does not show the code coverage for triggers or the overall code coverage percentage.
* B. View the Class Test Percentage tab on the Apex Class fist view m Salesforce Setup. This option does not exist in Salesforce Setup. There is no such tab or view for Apex classes.
* D. Select and run the class on the Apex Test Execution page in the Developer Console. This option only runs the test methods in the selected class, but does not show the code coverage for the class or other classes and triggers in the org.
