Apex Triggers & Coding Scenarios
1Write a trigger that shows the number of Contacts in an Account field.
2Write a trigger where the number entered on an Account field decides how many Contacts must be associated.
3What are the trigger events and trigger context variables?
4Instantiate a Map with Account Id as key and related Contacts as a list, then add elements to it.
5How does a trigger work for 1,000 records, and does it run in chunks as separate transactions?
6A trigger must update more than 10K records. How do you handle it?
7What are the best practices for triggers, and what if there are multiple triggers on the same object?
8How do you handle a CPU timeout error?
9Write a trigger that updates the Account rating from the number of Opportunities: fewer than 3 is Cold, 3 to 5 is Warm, more than 5 is Hot.
10What is the difference between isNull and isBlank?
11Write a SOQL query to fetch all Accounts having at least one associated Contact.
12Account has a Primary Contact Phone text field and Contact has an Is Primary Contact checkbox. An Account cannot have more than one primary Contact. When a new primary Contact is created, update the Account phone and unmark the other Contacts. Write the trigger.
13If a user has no access to a field, what error does the trigger throw, and what error appears on update?
14Why do we use oldMap in a trigger?
15A trigger has three queries returning 30k, 20k and 10k records. Will it cause an error or succeed?
Batch, Future & Async Apex
16What is the batch start method return type?
17Implement a @future method ProcessAccountAsync that updates a custom field after a configurable delay.
18What is the difference between getQueryLocator and an Iterable in batch?
19How do you apply error handling and logging with try-catch and System.debug?
20How would you apply performance best practices such as selective queries and async patterns?
21Write a test class that covers positive and negative cases and bulk data for the trigger and batch.
22How would you use Custom Settings or Custom Metadata for user assignments, delays and API endpoints?
23Build a batch that deactivates Accounts with no activity in the last 30 days or sends an email on a customer's birthday, with error handling and logging.
24What is the @future annotation?
25What are the methods of a batch class?
26How do you handle an update when a trigger has to process very large data?
27Why are test classes important, beyond initial testing?
28Build a trigger that creates a Contact when an Account Industry is Technology and assigns Account ownership from a Custom Setting.
Lightning Web Components
29A is the parent and B and C are children. How do B and C communicate?
30In a datatable LWC, I deleted a record but still see it. Why?
