EC-COUNCIL EC-Council Blockchain Fintech CertificationB|FC exam 312-82 Prüfungsfragen mit Lösungen (Q30-Q35):

30. Frage
________is used to split up the tasks into multiple chunks that are then processed by multiple nodes.

A. Fragmenting
B. Sharding
C. Partitioning
D. Parsing

Antwort: B

Begründung:
Shardingis a scalability technique that splits tasks or data into smaller, more manageable pieces called
"shards." These shards are then processed in parallel by multiple nodes in a network. By dividing the workload, sharding can significantly enhance the efficiency and speed of blockchain networks, which is especially beneficial for handling large transaction volumes and complex computations.
Key Details:
* Purpose of Sharding: The main goal of sharding is to address blockchain scalability issues. By enabling the network to process transactions and data in parallel, it reduces the load on individual nodes, thus increasing the overall throughput of the blockchain.
* How Sharding Works: In a sharded blockchain, each node only needs to process a portion of the total data rather than every single transaction on the network. Each shard is responsible for a subset of data and transactions, and only nodes within a particular shard need to validate its transactions.
* Relevance in Blockchain: Sharding is crucial in large-scale blockchain networks like Ethereum, where high transaction volumes can lead to congestion. Ethereum 2.0, for example, incorporates sharding as a core feature to improve its scalability and transaction processing capacity.
Sharding is, therefore, the correct answer, as it directly refers to the method of dividing tasks for parallel processing in a distributed environment.

31. Frage
______is designed to allow easy deployment of bloodchains.

A. Cello
B. Quit
C. Caliper
D. Composer

Antwort: A

Begründung:
Hyperledger Cellois designed to facilitate the deployment and management of blockchain networks. It provides an easy-to-use framework for creating, managing, and scaling blockchain networks, making it suitable for rapid deployment and operation. Although the term "bloodchains" might be a typo or intended for
"blockchains," Cello indeed simplifies the blockchain setup process for various applications.
Key Details:
* Deployment and Management: Cello offers a suite of tools that automates blockchain deployment, operation, and monitoring, making it accessible for businesses looking to adopt blockchain technology with minimal effort.
* Modular Approach: It supports various blockchain frameworks, including Hyperledger Fabric, and is aimed at reducing the complexity involved in blockchain management.
* Use Cases: Hyperledger Cello is useful for enterprise blockchain applications, as it allows administrators to manage blockchain networks with tools that support configuration, monitoring, and scaling.
Thus,B. Cellois the correct answer, as it simplifies blockchain deployment and management.

32. Frage
_______uses a Trusted Execution environment (TEE) to provide randomness and safety in the leader election process via a guaranteed wait time.

A. PoET
B. PoD
C. Pol
D. PoA

Antwort: A

Begründung:
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.

33. Frage
A________in a new chain and requires clients to upgrade in order to participate on the new blockchain.

A. Sub chain
B. Sharding
C. Soft fork
D. Hard fork

Antwort: D

Begründung:
Ahard forkoccurs when there is a fundamental change in a blockchain's protocol, resulting in the creation of a new chain that is incompatible with the previous one. After a hard fork, nodes must upgrade to the new version of the blockchain's software to continue participating in the network. A hard fork can be used to implement new features, fix security issues, or change core aspects of the blockchain.
Key Details:
* Differences from Soft Forks: Unlike a soft fork, which is backward-compatible and allows nodes on the previous version to still participate, a hard fork splits the blockchain into two distinct paths, with the upgraded path requiring new software.
* Examples: Notable hard forks include Bitcoin Cash from Bitcoin and Ethereum Classic from Ethereum. These forks occurred due to disagreements within the community on how to handle certain protocol changes, leading to the creation of separate blockchains.
* Upgrade Requirements: Participants on the blockchain who wish to continue on the new chain after a hard fork must update their software. Those who do not upgrade remain on the original chain, which continues as a separate, incompatible blockchain.
Thus, the correct answer isHard fork (A), as it directly refers to a blockchain split that requires client upgrades for participation.

34. Frage
The financial Action Task force defines virtual asset providers as companies that (choose two):

A. Purchase virtual currency
B. Transfer virtual assets
C. Exchange virtual assets for fiat currency
D. Sell products for virtual currency

Antwort: B,C

Begründung:
TheFinancial Action Task Force (FATF)definesVirtual Asset Service Providers (VASPs)in its guidelines to include entities that engage in theexchange of virtual assets for fiat currencyand thetransfer 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 currencyandD. Transfer virtual assetsare the correct answers, as they align with the FATF's definition of VASPs.
