Apex Triggers & Coding Scenarios
1What are the trigger events and the purpose of each?
2What are the best practices for triggers? (Expect cross questions on each point.)

17What are the ways to avoid trigger recursion?
18Write a roll-up summary trigger that counts the Contacts on an Account.
19Write a trigger to prevent deleting an Account that has related Contacts.
20Write a trigger that updates Opportunities older than 30 days (and not Closed Won) to Closed Lost whenever Account details are updated.
21Write a trigger to stop users from creating a Contact if another Contact with the same email or phone already exists.
22What is the order of execution in Salesforce? Which runs first for a before insert: the flow or the trigger?
23Write a roll-up trigger on the parent object.
24Write a trigger that updates the Billing City on all related Contacts when an Account's Billing City changes.
25Write code with Account Name as the key and its Contacts as the value.
