問題文
An operations lead is wary of the migration tool because the team has never run one before, and asks what the tool takes on by itself and whether it has to be driven once for each database in a set of thirty. What do the documented benefits of the tool say?
選択肢
- The automation takes in the transfer of the data only, so the checks before the move and the final cutover are run by hand, no fleet being covered, and the databases in a set cannot be driven together.
- The automation takes in every step including the change of the application connection strings, and the set of thirty is handled as one job that cannot be split.
- The automation takes in the whole set of checks made before the move plus the transfer of the data plus the final cutover, and the tool is described as covering a single database or a fleet so a set does not have to be driven once for each one, and it follows the availability practice at Oracle.
- The automation takes in the checks before the move and the transfer of the data, but the tool is described as covering one database at a time, a set of them being a matter for the migration service instead, so a run of thirty would be handed over to that service rather than driven here, one job to a database and one report to a job.
