CBSA - Certified Blockchain Solution Architect Blockchain Use Case Analysis Questions and Answers

Question 1

A healthcare consortium wants to build a platform for managing clinical trial data.
The primary goals are to ensure data integrity, prevent tampering with results, and give patients more control over how their data is shared with researchers.
All actions, such as a patient granting consent or a researcher accessing a dataset, must be immutably logged and auditable by regulators.
Which blockchain characteristic is MOST critical to meeting the data integrity and auditability requirement?

Accepted Answer

Immutability, as it ensures that once a transaction is recorded, it cannot be altered or deleted.

Answer

Decentralization, as it removes the need for a central administrator.

Answer

Tokenization, as it allows for the creation of digital assets representing patient data.

Answer

Anonymity, as it protects the identities of the patients and researchers.

Question 2

A group of venture capitalists is forming an investment collective. They want to democratize the decision-making process for funding startups, allowing all members to vote on proposals transparently. They also need a mechanism to pool capital and automatically distribute returns based on agreed-upon rules. Which blockchain-based organizational structure is best suited for this use case?

Accepted Answer

A Decentralized Autonomous Organization (DAO)

Answer

A public permissionless network

Answer

A self-sovereign identity (SSI) system

Answer

A supply chain tracking ledger

Question 3

A startup aims to tokenize high-value commercial real estate to enable fractional ownership. A primary challenge they face is convincing traditional real estate investors, who are unfamiliar with digital assets, to participate. This involves overcoming skepticism and demonstrating the legal and technical viability of the platform. Which of the following represents the MOST significant barrier to adoption for this use case?

Accepted Answer

Regulatory uncertainty and the need for investor education.

Answer

Lack of high-speed consensus mechanisms.

Answer

The inability of blockchain to store large property deed documents.

Answer

High energy consumption associated with Proof of Work.

Question 4

A government agency is exploring a Self-Sovereign Identity (SSI) solution to improve citizen services. The goal is to provide individuals with a digital wallet where they can store verified credentials (e.g., driver's license, passport) and present them to different departments without a central database controlling their data. What is the primary benefit of using a blockchain-based SSI model for the individual citizen?

Accepted Answer

It gives the user full control and ownership over their personal identity data.

Answer

It guarantees faster transaction speeds for all government services.

Answer

It provides complete anonymity, hiding the citizen's identity from the government.

Answer

It eliminates the need for any form of identity verification by government agencies.

Question 5

An international corporation is analyzing the use of blockchain for its cross-border payment operations to reduce costs and settlement times. In the traditional system, payments pass through multiple correspondent banks, each adding fees and delays. How does a blockchain-based solution primarily address this inefficiency?

Accepted Answer

By enabling peer-to-peer value transfer that reduces or eliminates intermediaries.

Answer

By using public-key cryptography to encrypt all payment messages.

Answer

By replacing the SWIFT messaging system with a more modern API.

Answer

By converting all payments into a volatile cryptocurrency like Bitcoin.

Question 6

A consortium is creating a blockchain-based platform for trading voluntary carbon credits. A key requirement is to prevent the 'double counting' of credits, where the same credit is sold or claimed multiple times. How does tokenizing carbon credits on a blockchain solve this specific problem?

Accepted Answer

By assigning a unique digital token to each verified carbon credit, which can be tracked from issuance to retirement on an immutable ledger.

Answer

By making all transaction data permanently public and transparent.

Answer

By using smart contracts to automatically purchase credits when emissions are reported.

Answer

By increasing the liquidity of the carbon market, making it easier to buy and sell credits.
