Nearly all the advisors submit their analysis activities to the database in the form of a job. When the analysis job is submitted, which option for job scope adds the least overhead to the system?

When submitting advisor analysis jobs, the 'Limited' scope adds the least overhead because it performs minimal analysis. 'Restricted' is not a valid job scope option in this context. 'Comprehensive' and 'Thorough' (though 'Thorough' is not standard Oracle terminology) would involve deeper analysis with more system overhead. Limited scope is the lightweight option for minimal system impact.
