   What is a primary data consistency challenge in an interoperable BaaS environment?

   • AEnsuring that all transactions are processed instantly
   • BEnsuring that all blockchains use the same consensus algorithm
   • CEnsuring that all data is stored on a single central server
   • DEnsuring that the same asset or data has the same state across multiple connected blockchains

   A trade finance consortium uses a BaaS platform to digitize letters of credit. The platform must interoperate with a legacy document management system and a partner bank's blockchain. The consortium wants to ensure that the letter-of-credit status updates are consistent across all systems. Which combination of mechanisms should the consortium implement?

   • AUse a sidechain to mirror the partner bank's blockchain and a REST API for the legacy system.
   • BUse Hyperledger Cactus to connect the two blockchains and ignore the legacy system.
   • CUse an atomic swap to synchronize the letter-of-credit status between the two blockchains.
   • DUse ISO 20022 messages for status updates and a middleware adapter to translate them for the legacy system.

   What is the primary purpose of a cross-chain bridge in a BaaS platform?

   • ATo convert smart contracts written in one programming language into another
   • BTo increase the transaction speed of a single blockchain
   • CTo provide a backup copy of all blockchain data on a separate server
   • DTo enable the transfer of assets or data between two different blockchain networks

   A cross-border payment provider uses a BaaS platform to settle payments between banks in different countries. The provider needs to ensure that payments are settled atomically across the banks' different blockchains, and it also needs to provide a common message format for transaction status. Which combination of mechanisms should the provider implement?

   • AAtomic swaps for settlement and ISO 20022 for status messages.
   • BHyperledger Cactus for settlement and custom JSON for status messages.
   • CSidechains for settlement and REST APIs for status messages.
   • DCross-chain bridges for settlement and Interledger Protocol for status messages.
