NEW QUESTION # 75
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 1 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?
- A. There will be no error, since each trigger fires within its own context and each trigger does not exceed the limit of the number of records processed by DML statements.
- B. The mass update of Account address will succeed, but the Contact address updates will fail due to exceeding number of records processed by DML statements.
- C. There will be no error, since the limit on the number of records processed by DML statements is 50,000.
- D. The mass update will fail, since the two triggers fire in the same context, thus exceeding the number of records processed by DML statements.
Answer: A
NEW QUESTION # 76

NEW QUESTION # 77
A developer created and tested a Visualforce page in their developer sandbox, but now receives reports that user encounter view state errors when using it in production.
What should the developer ensure to correct these errors?
- A. Ensure profiles have access to the Visualforce page.
- B. Ensure properties are marked as private,
- C. Ensure variables are marked as transient.
- D. Ensure queries do net exceed governor limits,
Answer: C
Explanation:
The developer should ensure variables are marked as transient to correct the view state errors. The transient keyword is used to mark a variable as transient, which means that the variable is not part of the view state, and it is not persisted or transferred between the server and the client. The developer should use the transient keyword for variables that are used for temporary storage or calculations, and that do not need to be retained across postbacks. This way, the developer can reduce the size of the view state, and avoid exceeding the view state limit. Ensuring queries do not exceed governor limits will not help, as it will only avoid hitting the SOQL query limit, but it will not reduce the size of the view state. Ensuring properties are marked as private will not help, as it will only limit the access to the properties, but it will not reduce the size of the view state. Ensuring profiles have access to the Visualforce page will not help, as it will only grant the permissions to view the page, but it will not reduce the size of the view state.
