EC-COUNCIL EC-Council Blockchain Fintech CertificationB|FC exam 312-82 Prüfungsfragen mit Lösungen (Q37-Q42):

37. Frage
______is a computer program that runs stop a blockchain and embedded within it are governance and business logic rules

A. DAC
B. DaS
C. Dapps
D. DAO

Antwort: C

Begründung:
Decentralized Applications (Dapps)are applications that run on a blockchain network and include embedded governance and business logic rules. Unlike traditional applications, Dapps are decentralized, meaning they operate on a peer-to-peer network rather than a centralized server, leveraging smart contracts to automatically enforce rules and protocols without intermediaries.
Key Details:
* Characteristics of Dapps: Dapps are open-source, operate autonomously, and store data on a blockchain. They utilize smart contracts to handle various functions, from transaction processing to enforcing governance rules and executing business logic.
* Smart Contracts: The embedded rules within Dapps are typically coded as smart contracts, which are self-executing contracts with the terms of the agreement directly written into lines of code. This ensures that all transactions and operations within the Dapp are transparent, immutable, and automatically enforced.
* Use Cases: Dapps are commonly found in areas such as decentralized finance (DeFi), gaming, supply chain management, and social media, offering users more control and transparency compared to traditional applications.
In conclusion,Dapps (A)is the correct answer as it refers to computer programs running on a blockchain with embedded governance and business logic rules.

38. Frage
What type of DApp allows every participant to remain totally anonymous?

A. Type II
B. Fully anonymous DApp
C. TypeI
D. Reputation based DApp

Antwort: B

Begründung:
AFully Anonymous DAppis a decentralized application that is designed to maintain complete anonymity for all participants. These DApps do not require user identity verification, and interactions are carried out in a manner that does not reveal personal information. Fully anonymous DApps are particularly popular in privacy- focused blockchain ecosystems.
Key Details:
* Privacy and Anonymity: Fully anonymous DApps employ various privacy-preserving techniques, such as zero-knowledge proofs or ring signatures, to ensure that user transactions and interactions cannot be traced back to their identities.
* Use Cases: Fully anonymous DApps are often used in applications where privacy is paramount, such as private transactions, anonymous messaging, and confidential voting systems. By design, they prioritize user anonymity over other features.
* Comparison with Other DApp Types: While other DApp types might include some level of user identification or reputation systems, fully anonymous DApps offer total anonymity, making them ideal for users who require privacy at all levels of interaction.
Therefore,A. Fully anonymous DAppis the correct answer, as it describes a DApp that allows participants to remain completely anonymous.

39. Frage
_______implements the interledger protocol, which facilitates interoperability across different distributed and non-distributed ledger networks.

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

Antwort: B

Begründung:
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.

40. Frage
Proof of work algorithms are best described as being used for what?

A. Proof that adequate computational resources have been sent.
B. Executing transactions
C. Bitcoin mining
D. Proving the user has invested enough in the system

Antwort: A

Begründung:
Proof of Work (PoW)algorithms are primarily used to demonstrate that sufficient computational resources have been expended by a participant to validate transactions and add them to the blockchain. In PoW, miners compete to solve a cryptographic puzzle, which requires significant computational power. This effort helps secure the network by making it prohibitively expensive for any individual or group to alter the blockchain's history.
Key Details:
* Mechanism of PoW: The essence of PoW is to prove that a certain amount of computational work has been performed. This "work" is measured by the effort miners invest in solving the cryptographic puzzle. The process requires miners to find a nonce that, when hashed with the block's data, results in a hash that meets the network's difficulty requirements.
* Security and Integrity: By proving computational work, PoW ensures that miners cannot simply fabricate or alter transactions without a significant investment of resources. This mechanism deters attacks and makes blockchain networks resistant to tampering and double-spending.
* Association with Bitcoin Mining: Although PoW is often associated with Bitcoin mining (as miners expend computational resources to validate and record transactions), its broader purpose is to establish a cost for participation in the network, ensuring that all entries to the blockchain are trustworthy and secure.
Therefore, PoW is best described as a mechanism for proving that adequate computational resources have been expended, aligning with the correct answer B.

41. Frage
These wallets use a this passphrase to derive the private key

A. Hierarchical Deterministic Wallets
B. Non-Deterministic Wallets
C. Brain Wallets
D. Deterministic Wallets

Antwort: C

Begründung:
Brain Walletsderive private keys from a passphrase. This approach allows users to create a wallet by memorizing a unique phrase, which is then hashed to generate the corresponding private key.
Key Details:
* Use of Passphrases: Brain wallets use a passphrase that is entered by the user, typically a string of words that can be remembered easily. This passphrase is then converted into a private key using a cryptographic hash function.
* Security Concerns: While convenient, brain wallets are susceptible to brute-force attacks if the passphrase is not sufficiently complex. Simple or common phrases may be vulnerable to attackers who use lists of common phrases to derive potential private keys.
* Distinction from Deterministic Wallets: Unlike Hierarchical Deterministic Wallets, which use a seed phrase to generate a tree of keys, brain wallets derive a single private key directly from a passphrase.
In conclusion,B. Brain Walletsis the correct answer, as these wallets use a passphrase to generate the private key.
