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?

The mass update will fail, since the two triggers fire in the same context, thus exceeding the number of records processed by DML statements.

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.

There will be no error, since the limit on the number of records processed by DML statements is 50,000.

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.

Question 29

Sometimes events on Salesforce need to be handled by an external system due to the scale or type of process being executed. Consider the use case of a user in Salesforce needing to get pricing for an order they are building in Salesforce while on the phone with a customer. The pricing logic already exists in a third-party system. Instead of recreating this logic in Salesforce, it will be leveraged by making a request of the third-party system. The response, in this case the pricing, will be returned and stored back in Salesforce. What is the optimal solution?

A Visualforce page that can make a real-time Apex callout to display and save the pricing back in Salesforce

An Apex trigger that upon saving the Order will make a real-time Apex callout, saving the pricing back in Salesforce

A Process Builder process and Outbound Message to fetch the pricing upon save and store the pricing in Salesforce

An ETL tool to process batches of newly saved Orders every few minutes to store the pricing back in Salesforce
