Correct Answers: A. LastModifiedDate, C. Name, and D. SystemModStamp

✅ A. LastModifiedDate
Yes, indexed.

Helps in filtering records based on last update time, commonly used in syncs and SOQL filters.

❌ B. CreatedBy
Not indexed by default.

You can filter by CreatedById, but it is not one of the standard indexed fields unless a custom index is requested via Salesforce support.

✅ C. Name
Yes, indexed.

This is often used in queries and list views. Salesforce indexes Name fields for standard objects (like Account, Contact, etc.).

✅ D. SystemModStamp
Yes, indexed.

Used internally by Salesforce and in APIs. It’s preferred over LastModifiedDate for integrations and is indexed.

❌ E. RecordType
Not indexed by default.

Although it's commonly used in filtering, it's not indexed unless manually requested through Salesforce support.

Name, SystemModStamp and RecordType are indexed
