EC-COUNCIL EC-Council Blockchain Fintech CertificationB|FC exam Sample Questions (Q17-Q22):
NEW QUESTION # 17
What is the primary way blockchain could help in the food industry?
- A. Eliminating food born illness
- B. Making transaction ore transparent
- C. Making transport safer
- D. Streamlining management
Answer: B
Explanation:
Blockchain can greatly benefit the food industry bymaking transactions more transparent. By recording each transaction in an immutable ledger, blockchain enables traceability, which is crucial for food safety, quality control, and ensuring that products meet regulatory standards.
Key Details:
* Traceability: Blockchain allows for the tracking of food products from farm to table. Each step in the supply chain can be recorded on the blockchain, providing consumers and regulators with transparent information about the origin and journey of food products.
* Improving Trust and Safety: With transparent transactions, stakeholders can quickly identify and address issues such as contamination, fraud, or mislabeling, which enhances food safety and consumer trust.
* Enhanced Efficiency: By reducing paperwork and enabling digital record-keeping, blockchain streamlines the process of verifying and sharing information about food products across various parties.
Thus,C. Making transactions more transparentis the correct answer, as it highlights blockchain's role in providing transparency in the food industry.
NEW QUESTION # 18
________can support up to 10-14 transactions per second.
- A. Zcash
- B. Bitcoin
- C. Ethereum
- D. copyright
Answer: C
Explanation:
Ethereumcurrently supports a transaction throughput of approximately10-14 transactions per second (TPS)
. This transaction speed is a result of Ethereum's design, which balances decentralization and security, albeit at the cost of scalability. This TPS rate is consistent across the Ethereum network prior to its upgrade to Ethereum 2.0, which aims to increase scalability through sharding and Proof of Stake.
Key Details:
* Limitations of Current Throughput: Ethereum's TPS rate is due to limitations in its consensus mechanism (formerly Proof of Work, now Proof of Stake) and block size, which prioritize security over transaction speed.
* Comparison with Other Networks: Bitcoin, for example, supports around 3-7 TPS, while other networks like Solana or copyright Smart Chain support significantly higher TPS. Ethereum's TPS may increase as Ethereum 2.0 is fully implemented, which aims to improve its scalability.
* Impact on Decentralized Applications (copyright): Ethereum's transaction capacity impacts copyright running on the network, as higher usage can lead to congestion and increased transaction fees(gas fees).
The upcoming upgrades are intended to alleviate these issues and enhance performance.
Therefore,D. Ethereumis the correct answer, as it supports approximately 10-14 TPS in its current form.
NEW QUESTION # 19
These wallets store keys in a tree structure derived from a seed.
- A. Deterministic Wallets
- B. Non-Deterministic Wallets
- C. Brain Wallets
- D. Hierarchical Deterministic Wallets
Answer: D
Explanation:
Hierarchical Deterministic (HD) Walletsare wallets that generate private and public keys in a tree structure, starting from a single seed phrase. This seed phrase can generate multiple key pairs, allowing users to back up and recover all their wallet addresses using one phrase, which enhances security and convenience.
Key Details:
* Tree Structure: HD wallets use a root seed to derive an entire hierarchy of keys. Each branch in the tree can create new sub-branches, generating separate addresses for different transactions without reusing them, which provides better privacy.
* Seed-Based Recovery: Users can restore all wallet addresses with the original seed phrase, making HD wallets more secure and easy to back up compared to non-deterministic wallets, which would require individual backups for each key.
* Compatibility with Blockchain Standards: HD wallets adhere to the BIP32 and BIP44 standards, which outline the derivation paths and formats used by these wallets. This compatibility allows for interoperability among different wallet providers.
In conclusion, Hierarchical Deterministic Wallets (answer B) best describes wallets that store keys in a tree structure derived from a seed.
NEW QUESTION # 20
Ethereum uses_____ as Proof of Work (PoW) whereas Bitcoin uses____based PoW.
- A. SHAZ56 ETHASH
- B. PoW PoB
- C. PoB BoW
- D. ETHASH SHA-256
Answer: D
Explanation:
Ethereum uses Ethashas its Proof of Work (PoW) algorithm, whileBitcoin uses SHA-256for 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-256is the correct answer, as these are the specific PoW algorithms used by Ethereum and Bitcoin, respectively.
NEW QUESTION # 21
What is the term for the smallest subunit in Ether.
- A. ETH
- B. Bitcoin
- C. Gas
- D. Wie
Answer: D
Explanation:
The smallest subunit of Ether is called aWei. Ether (ETH) is divided into several subunits for precision in transactions, with Wei being the smallest, equivalent to 10#1810
