Final answer:
The RDO likely updates the inventory to reflect the issued cables, ensuring that the inventory records are accurate after the issuance of two connector cables.
Step-by-step explanation:
When the Requisition Disposition Output (RDO) is input following the report of three excess connector cables and the issuance of two of them, the most likely outcome is that the system updates the inventory to reflect the issued cables.
This means that the inventory records will be adjusted to account for the two cables that have been issued, leaving the status of any remaining excess cables to be determined by subsequent disposition instructions.
