You need to recommend a solution to minimize the amount of time it takes to execute USP_5. What should you include in the recommendation?

Cross-database ownership chaining allows SQL Server to skip permission checks on intermediate objects when the owner chain is unbroken across databases, reducing the security validation overhead each time USP_5 accesses objects in other databases. Without it, SQL Server must verify permissions at every cross-database boundary, adding latency. Enabling cross-database chaining removes these redundant checks and minimizes execution time.

Using a server role to group logins simplifies permission management and administration but does not reduce the number of security checks performed at runtime during stored procedure execution, so it would not minimize execution time.

The EXECUTE AS clause changes the execution context of the stored procedure for security impersonation purposes, but it does not eliminate cross-database permission checks and would not reduce the execution time caused by inter-database security validation.

Copying USP_5 to each database would create maintenance complexity and redundancy, and would not address the cross-database permission check overhead that is causing the slow execution time.
