   A regional credit union is migrating its loan origination process to a blockchain-based system. The credit union cannot afford a big-bang cutover because loan officers must continue serving members during the transition. Which phased integration strategy is most appropriate?

   • AImmediately decommission the legacy system and rely solely on the blockchain system from day one.
   • BRun the blockchain system in parallel with the legacy system for a defined period, then switch over once reconciliation is validated.
   • CMigrate only the loan approval step to blockchain while leaving all other steps on legacy systems indefinitely.
   • DUse a blockchain system only for new loans and keep all existing loans on the legacy system permanently.

   A global bank is integrating blockchain into its correspondent banking network. The bank must maintain real-time liquidity management across multiple currencies while gradually migrating from legacy systems. The bank also faces regulatory requirements to report cross-border transactions in real time. Which integration strategy best balances these competing needs?

   • AA phased hybrid model where blockchain handles new transactions and legacy systems handle existing ones, with real-time data synchronization and regulatory reporting.
   • BA full replacement model where all legacy systems are decommissioned immediately.
   • CA manual reconciliation model where data is transferred between systems at the end of each day.
   • DA standalone blockchain model with no integration to legacy systems.
