A financial institution is integrating a blockchain-based settlement system with its existing core banking platform. The institution needs to ensure that transactions are processed in real time and that the integration does not introduce a single point of failure. Which technical integration approach best meets these requirements?

Use a batch processing approach to reduce the load on the middleware.

Deploy a redundant middleware cluster with load balancing and failover capabilities.

Use a single middleware server to simplify the integration.

Integrate directly from the core banking database to the blockchain without middleware.

A payment processor is integrating a permissioned blockchain to handle real-time transaction settlement. The current system processes thousands of transactions per second, and the blockchain must not become a bottleneck. Which performance integration strategy is most appropriate?

Increase the block size to an unlimited size so all transactions fit in one block.

Implement off-chain channels for high-frequency transactions and settle only final balances on-chain.

Use a single blockchain node to process all transactions sequentially to maintain a simple design.

Disable consensus mechanisms to allow faster transaction processing.

What is a common scalability challenge when integrating blockchain into a high-volume financial environment?

The blockchain network cannot be accessed over the internet.

The blockchain network requires more storage space than traditional databases.

The blockchain network may have a limited transaction throughput compared to traditional payment systems.

The blockchain network is always slower than any centralized system.

What is the primary goal of change management in the context of blockchain integration in a financial institution?

To minimize disruption to business operations while transitioning to the new blockchain-based processes.

To eliminate the need for any governance framework.

To replace all existing IT staff with blockchain specialists.

To ensure that the blockchain network is always running at maximum speed.

A financial services firm is evaluating how to integrate blockchain with its existing trade settlement infrastructure. The firm wants to maintain a single source of truth while gradually moving to blockchain. Which integration model best fits this requirement?

A full replacement model where the blockchain immediately replaces all legacy systems.

A standalone model where blockchain operates independently with no connection to legacy systems.

A hybrid model where blockchain and legacy systems coexist, with data synchronized between them.

A manual model where data is manually transferred between blockchain and legacy systems.
