Consider the queries in the options below and the following Information:
* For these queries, assume that there are more than 200,000 Account records.
* These records Include soft-deleted records; that is, deleted records that are still in the Recycle Bin.
* There are two fields that are marked as External Id on the
Account. These fields are customer_Number_c and ERR_Key_ s.
Which two queries are optimized for large data volumes?
Choose 2 answers

A. SELECT Id FROM Account WHERE Name != ' 'AND IsDeleted = false
B. SELECT Id FROM Account WHERE Name !- NULL
C. SELECT ID FROM Account WHRE id IN :aListVariable
D. SELECT 1d FROM Accounts WHERE Name != '
AND Customer_Number_c- "ValueA'

答案：A,D

解題說明：
For optimizing queries, especially on large data volumes, it's recommended to use indexed fields such as External ID fields, which will make the queries selective. Among the options given:
* B) is optimized because it is using the Customer_Number__c field, which is an External ID and hence indexed.
* D) is also optimized because it filters out deleted records with IsDeleted = false and uses Name != ' ', which is likely to be selective.
Using indexed fields and filtering out unnecessary records helps in faster query execution on large data volumes.
