SSC Clinic: Can Implementing "Optimize for Ad Hoc Queries" Boost Performance for the SQLServerCentral.com and Simple-Talk.Com SQL Servers?

With the introduction of the instance-level option “optimize for ad hoc workloads” in SQL Server 2008, DBAs have a tool to deal with a problem known as plan cache pollution, or plan cache bloat. It’s often caused when one-time use ad hoc queries are sent to SQL Server from Object-Relational Mapping (ORM) solutions, such as LINQ, NHibernate, or Entity Framework. The problem can prevent SQL Server from using its available memory optimally, potentially hurting performance.

Rebuilding All Indexes

I have added a few indexes to one of my tables in SQL Server 2025: 

ALTER TABLE dbo.CustomerContact
ADD CONSTRAINT PK_CustomerContact
    PRIMARY KEY (CustomerID);

-- Create index on CustomerEmail
CREATE INDEX IX_CustomerContact_CustomerEmail
ON dbo.CustomerContact (CustomerEmail);
CREATE INDEX IX_CustomerContact_CustomerEmail
ON dbo.CustomerContact (phone);
I then do this to disable one index: 
alter index IX_CustomerContact_CustomerPhone on dbo.CustomerContact disable
I see this when I check the index status:Index status for CustomerContactI decide to rebuild all indexes with this command: 
ALTER INDEX ALL ON dbo.CustomerContact
After I do this, what will I see for the index status?
