Security in Blockchains, Blockchain Project Implementation, and Ethereum typically account for a larger portion of the exam. These areas test both conceptual understanding and the ability to make sound architectural and security decisions in real projects. Allocate extra study time to these domains and practice scenario-based questions that combine multiple concepts.
A typical project starts with Introduction and project planning (Blockchain Project Implementation), moves into architecture selection (BaaS, Bitcoin, Ethereum), incorporates security controls (Security in Blockchains), and delivers a user-facing application (dApps). Financial Applications and Insurance Applications show how these technical foundations support business outcomes. Understanding these connections helps you answer scenario questions more confidently.
Deploying a smart contract on Ethereum, configuring a node on a managed BaaS platform, and reviewing real smart contract code for security issues are the most practical labs. If possible, build a small dApp that connects a wallet, retrieves blockchain data, and executes a transaction. Hands-on experience makes scenario questions feel more intuitive and reduces test anxiety.
Confusing permissioned and permissionless network trade-offs, underestimating the importance of gas optimization in Ethereum, and overlooking security implications of open-source components are frequent errors. Another common mistake is selecting a consensus mechanism without considering the specific use case (e.g., choosing proof-of-work for a private insurance network). Always ask yourself why a choice is correct for the given scenario, not just whether it is a valid option.
In the final week, spend 60% of your time on scenario-based and configuration items, 20% on high-weight topics (Security in Blockchains and Blockchain Project Implementation), and 20% on weak areas you identified in practice tests. Do one full-length timed practice test three days before the exam, review all incorrect answers, and use the last two days for targeted review of concepts, not new material. On exam day, read each scenario carefully and eliminate obviously wrong answers before selecting your choice.
Ethereum uses_____ as Proof of Work (PoW) whereas Bitcoin uses____based PoW.
Ethereum uses Ethash as its Proof of Work (PoW) algorithm, while Bitcoin uses SHA-256 for its PoW algorithm. Both are used to secure their respective networks, but they differ in terms of computational complexity and memory requirements.
Key Details:
Ethash (Ethereum): Ethash is a memory-hard hashing algorithm designed to be resistant to ASIC mining, favoring GPU miners instead. It requires substantial memory, which helps to ensure a higher degree of decentralization.
SHA-256 (Bitcoin): Bitcoin's SHA-256 is a highly secure hashing algorithm that supports ASIC mining. It is computationally intensive but less memory-demanding compared to Ethash.
Purpose in PoW: Both algorithms enable miners to validate transactions and secure the network by solving complex puzzles. Ethash's design helps Ethereum maintain a decentralized network, whereas SHA-256 allows Bitcoin to achieve high levels of security with specialized mining equipment.
Therefore, D. ETHASH SHA-256 is the correct answer, as these are the specific PoW algorithms used by Ethereum and Bitcoin, respectively.
The financial Action Task force defines virtual asset providers as companies that (choose two):
The Financial Action Task Force (FATF) defines Virtual Asset Service Providers (VASPs) in its guidelines to include entities that engage in the exchange of virtual assets for fiat currency and the transfer of virtual assets. This categorization is part of the FATF's efforts to regulate and monitor the flow of virtual assets to mitigate risks associated with illicit activities.
Key Details:
Exchange and Conversion Services: FATF recognizes companies that offer exchange services between virtual assets and fiat currencies as VASPs. These services are critical for converting virtual assets into forms that can be readily used in traditional markets.
Transfer Services: VASPs that facilitate the transfer of virtual assets are also within the FATF's regulatory scope. This includes services that manage, transfer, or act as intermediaries in the movement of virtual assets between users, ensuring these transactions are conducted transparently and within regulatory frameworks.
Therefore, C. Exchange virtual assets for fiat currency and D. Transfer virtual assets are the correct answers, as they align with the FATF's definition of VASPs.
_______uses a Trusted Execution environment (TEE) to provide randomness and safety in the leader election process via a guaranteed wait time.
Proof of Elapsed Time (PoET) is a consensus mechanism that uses a Trusted Execution Environment (TEE) to ensure randomness and safety in the leader election process by enforcing a guaranteed wait time. Developed by Intel, PoET is particularly used in permissioned blockchain networks where a TEE can securely run code to determine which node is elected to propose the next block. This mechanism is efficient in terms of energy consumption and provides a fair method for selecting a leader without requiring intensive computational power.
Key Details:
Role of TEE in PoET: The TEE ensures that nodes wait for a random period before being eligible to propose a new block. This waiting period is verified by the TEE, which acts as a trusted third party to confirm that nodes have adhered to the assigned wait time.
Randomness and Security: PoET provides randomness in the leader selection process, reducing the chances of any node gaining an unfair advantage. It also promotes security by leveraging the TEE, which is designed to prevent tampering with the waiting time calculations.
Use Cases: PoET is mainly used in permissioned blockchain environments like Hyperledger Sawtooth, where nodes are pre-approved, and there is a need for a scalable yet secure consensus mechanism.
In summary, PoET is the correct answer as it directly refers to a consensus mechanism that utilizes a Trusted Execution Environment for leader election.
According to FinCEN what dictates the obligations of money transmitters?
According to the Financial Crimes Enforcement Network (FinCEN), the obligations of money transmitters are determined primarily by the business model of the company. FinCEN regulations stipulate that companies engaged in money transmission services must comply with Anti-Money Laundering (AML) and Counter-Terrorism Financing (CTF) regulations, based on how they conduct their business rather than on their industry designation or self-description.
Key Details:
Regulatory Basis: FinCEN's guidelines are focused on the activities of the business---specifically, whether it facilitates the transfer of money or currency on behalf of others. This regulatory approach ensures that companies involved in money transmission are subject to appropriate oversight, regardless of their industry.
Activities Over Labels: Even if a company does not advertise itself as a money transmitter, it may still be subject to FinCEN regulations if its business operations fit the criteria for money transmission services.
Compliance Requirements: Money transmitters must register with FinCEN and implement AML/CTF measures to prevent illicit activities, aligning their compliance obligations with the nature of their operations.
Thus, C. The business model is the correct answer, as FinCEN focuses on the activities a company performs when determining regulatory obligations.
_______implements the interledger protocol, which facilitates interoperability across different distributed and non-distributed ledger networks.
The answer is (C) Quilt.
Hyperledger Quilt is a Java implementation of the Interledger Protocol (ILP). ILP is designed to transfer value across different ledgers, whether they are distributed ledgers (like blockchains) or traditional non-distributed ledgers.
Here's why the other options aren't the best fit:
Composer: Hyperledger Composer was a tool for building blockchain applications, but it has been deprecated.
Cello: Hyperledger Cello aims to provide a modular blockchain platform, making it easier to deploy and manage blockchain networks.
Caliper: Hyperledger Caliper is a benchmarking tool used to measure the performance of different blockchain implementations.
Quilt's primary function is to enable interoperability between different ledger systems, which is crucial for the broader adoption and integration of blockchain technology.
