Why is it recommended to avoid unnecessary fields on an object when designing for large data volumes?

To reduce the amount of storage used

To improve query performance by reducing the amount of data read

To reduce the number of objects in the org

A large enterprise has a custom object 'Case__c' with a lookup to 'Account__c'. One account has over 1 million cases, causing severe data skew. Users report that any query filtering on this account's cases times out. The architect is considering several mitigation strategies. Which strategy is most effective in reducing the impact of data skew?

Create a custom index on the Account__c lookup field.

Partition the cases into multiple custom objects based on the case type.

Use a skinny table that includes only the fields needed for the query.

Introduce an intermediate 'Case_Group__c' object to distribute the cases across multiple parent records.

What is the purpose of a query plan in Salesforce?

To show the number of records returned by a query

To show the execution order of Apex code

To show the CPU time used by a query

To show the estimated cost of a SOQL query and the indexes used
