An Apex method inserts a list of Accounts and then updates a list of Contacts. The Contact update fails because one Contact has an invalid email. The developer wants to ensure that if the Contact update fails, the Account insert is also rolled back. Which approach should be used?

Catch the exception and log it, then continue.

Use a savepoint before the Contact update and roll back to it in a catch block.

Use Database.update with allOrNothing set to false.

Do not catch the exception; let it propagate out of the method.

A developer needs to write a method that queries records from an object whose API name is stored in a custom setting. The query must be built at runtime because the object name is not known at compile time. Which approach should be used?

Use Schema.describeSObjects to get the object's fields and then query.

Use SOSL with the object name from the custom setting.

Use a static SOQL query with a placeholder for the object name.

Use Dynamic SOQL with a query string that includes the object name from the custom setting.
