NEW QUESTION # 35
These wallets store keys in a tree structure derived from a seed.

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

Answer: B

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 # 36
______is intended to provide a foundation for the development of blockchain solutions with a modular architecture.

A. FABRIC
B. Sawtooth
C. IROHA
D. Hyperledger Composer

Answer: A

Explanation:
Hyperledger Fabricis designed to provide a foundation for developing blockchain solutions with a modular architecture. Fabric, a project under the Hyperledger umbrella by the Linux Foundation, offers flexibility through its pluggable components, enabling enterprises to tailor blockchain networks according to their specific requirements.
Key Details:
* Modular Architecture: Hyperledger Fabric supports modular plug-ins for various functions, including consensus, identity management, and privacy settings. This allows organizations to customize the blockchain to suit their operational needs.
* Permissioned Network: Fabric is a permissioned blockchain, meaning that it restricts network participation to authorized entities, which is ideal for enterprise use cases that require confidentiality and controlled access.
* Enterprise-Grade Features: Fabric's architecture is well-suited for complex business processes, providing features like private data collections, which allow subsets of participants to create private channels for transactions.
Thus,B. FABRICis the correct answer, as it is specifically developed to support modular, enterprise-grade blockchain solutions.

NEW QUESTION # 37
These wallets contain randomly generated private keys and are also called just a bunch of key wallets.

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

Answer: B

Explanation:
Non-Deterministic Wallets, also known as"Just a Bunch of Keys" (JBOK)wallets, contain randomly generated private keys that are not derived from a single seed. In this type of wallet, each key is created independently and must be backed up individually, as there is no way to recover keys through a mnemonic seed phrase.
Key Details:
* Random Key Generation: Non-Deterministic wallets generate private keys independently, without a hierarchical or sequential structure. As a result, each key is standalone, and losing a key means losing access to the corresponding funds permanently.
* Backup Requirements: Since each key is unique and unrelated, Non-Deterministic wallets require separate backups for each key. This differs from Hierarchical Deterministic wallets, which can be restored using a single seed phrase.
* Use Case: These wallets were more common in the early days of cryptocurrency, but they are less favored today due to the convenience and recoverability provided by deterministic wallets.
In conclusion,C. Non-Deterministic Walletsis the correct answer, as it refers to wallets that contain randomly generated private keys and are known as JBOK wallets.

NEW QUESTION # 38
Proof of work algorithms are best described as being used for what?

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

Answer: D

Explanation:
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.

NEW QUESTION # 39
_______is a word use to describe technologies which store, distribute and facilitate the exchange of value between users, either privately or publicly

A. DAO
B. Ledger
C. Blockchain
D. DLT

Answer: D

Explanation:
Distributed Ledger Technology (DLT)is a broad term used to describe technologies that store, distribute, and facilitate the exchange of value between users, either privately or publicly. DLTencompasses various types of ledgers, including blockchains, where data is replicated, shared, and synchronized across a distributed network.
Key Details:
* Definition and Scope: DLT refers to a digital system for recording transactions across multiple locations simultaneously. It allows for decentralized data management and reduces the need for a central authority to maintain a ledger.
* Private and Public Ledgers: DLT can be implemented in both private (permissioned) and public (permissionless) networks. In public DLT, anyone can participate, while private DLT restricts access to authorized participants only.
* Examples of DLT: Blockchain is one form of DLT, but other types include Directed Acyclic Graphs (DAGs) and Hashgraph. Each of these has unique mechanisms for data storage and consensus.
Therefore,C. DLTis the correct answer, as it is the term that broadly covers technologies used for the exchange and storage of value in distributed systems.
