The server fault remains unresolved: An insurer's warm standby site has networking and some infrastructure but no tested application data replication; management assumes it offers hot-site recovery time. Which evidence should be examined first to diagnose this particular issue?
Inspect standby inventory, replication state, data freshness, test cutover duration and recovery contracts.

A CompTIA Server+ SK0-005 administrator reviews this production scenario: A payroll database spans remote cities; an architect requires zero committed transaction loss but uses long-distance asynchronous replication without documenting lag. Which configuration or design change most directly solves the requirement?
