Final answer:
True, upsert events cause both Insert and Update triggers to fire.
Step-by-step explanation:
True, upsert events do cause both Insert and Update triggers to fire. An upsert operation is a combination of an insert and an update operation. It allows you to insert a new record into a database table if it does not already exist, or update an existing record if it does. For example, if you have an upsert operation that attempts to insert a new record, and the record already exists, the insert trigger will fire but the update trigger will not. On the other hand, if the upsert operation updates an existing record, both the insert and update triggers will fire.
