CBC CBC Implementation & Project Management 2

Question 1

What is the key difference between a 'pilot' and a 'production' blockchain deployment?

Accepted Answer

Pilots test the solution with real users in a limited scope; production deploys at full scale with SLAs

Answer

Pilots use public blockchains; production uses private ones

Answer

Pilots require no governance model; production does

Answer

Pilots involve only developers; production involves only business users

Question 2

Which change management activity is most critical when transitioning an organization to a blockchain-based workflow?

Accepted Answer

Training end users on new processes and building internal champions

Answer

Purchasing additional server hardware

Answer

Rewriting all existing software contracts

Answer

Replacing the entire IT department

Question 3

A blockchain consultant is assessing integration complexity. Which factor most significantly increases integration risk?

Accepted Answer

Volume of legacy systems that must synchronize data with the blockchain in real time

Answer

Number of blockchain nodes in the network

Answer

Choice of programming language for smart contracts

Answer

Size of the project budget

Question 4

What is the primary purpose of a blockchain 'sandbox environment' in project implementation?

Accepted Answer

To provide an isolated development and testing environment that mirrors production without real consequences

Answer

To store production data with read-only access

Answer

To host the public-facing blockchain explorer

Answer

To run consensus nodes during the PoC phase only

Question 5

When defining success metrics for a blockchain implementation, which type of KPI is most meaningful to executive stakeholders?

Accepted Answer

Business outcome metrics such as cost reduction, cycle time, or reconciliation error rate

Answer

Transactions per second (TPS)

Answer

Number of smart contracts deployed

Answer

Node uptime percentage

Question 6

In a multi-party blockchain implementation, why is a 'data ownership and access rights' agreement critical before development begins?

Accepted Answer

It establishes who can read, write, and delete records, preventing disputes after immutable data is committed

Answer

It determines which consensus algorithm to use

Answer
