A utility billing database can tolerate only minutes of downtime, not a full weekend outage. Which database transfer mechanism should architects choose?
Select an answer to reveal the explanation.
Short Explanation
Billing cannot nap for a weekend while someone restores a dump. Use DMS with CDC so the database keeps humming and cutover is measured in minutes, not camping trips.
Full Explanation
Allowable downtime drives database transfer selection. Online DMS with CDC minimizes cutover downtime for low-RTO systems such as utility billing. Full offline dump restores, empty schema-only moves, and multi-week payment freezes violate the downtime constraint.
