Answer:
When Δ is set to large value, then a process's resident set is overestimated and this might prevent many processes from being scheduled even though their required pages are resident
Explanation:
When Δ is set to a small value, then the set of resident pages for a process might be underestimated, allowing a process to be scheduled even though all of its required pages are not resident.
This could result in a large number of page faults. When Δ is set to large value, then a process's resident set is overestimated and this might prevent many processes from being scheduled even though their required pages are resident.
Hoewever, once a process is scheduled, it is unlikely to generate page faults since its resident set has been overestimated.
