The correct answer is Cloud systems integrator.

A Cloud systems integrator is the specialist who links on premises systems with cloud services and who executes migrations for legacy applications. This role focuses on hands on work such as connecting networks, moving and transforming data, implementing integration middleware, and validating interoperability between the old and new environments.

Cloud compliance auditor is incorrect because that role focuses on assessing policies and controls and on verifying regulatory and security compliance rather than on performing system integration and migration work.

Cloud solutions architect is incorrect because architects typically produce high level designs, choose patterns, and provide guidance rather than doing the detailed, hands on integration tasks required to connect on premises systems to cloud services.

Cloud operations manager is incorrect because that role is oriented to running and overseeing ongoing operations and support after deployment rather than executing the migration and integration tasks needed during the move to the cloud.
