Complex key-value pairsB. Rich QueriesC. JSON data pairsD. Simple key-value pairsAnswer: DExplanation:Simple key-value pairs - LevelDB is the default and is particularly appropriate when ledger states aresimplekey-value pairs. A LevelDB database is closely co-located with a network node – it is embedded within thesame operating system process. CouchDB is a particularly appropriate choice when ledger states arestructured as JSON documents because CouchDB supports the rich queries and update of richer datatypesoften found in business transactions. Implementation-wise, CouchDB runs in a separate operating systemprocess, but there is still a 1:1 relation between a network node and a CouchDB instance. All of this isinvisibleto chaincode.Reference: se-1.3/ledger/ledger.htmlQuestion 2When creating a network according to an organization's structure and also bootstrap a channel what arethehttps://www.certification-questions.com
Blockchain CBDHfollowing artifacts we would need to generate?Options:A. Genesis Block, License File and Anchor Peer Configs for each organization.B. Genesis Block, ledger Configuration and Anchor Peer Configs for each organization.C. Genesis Block, Channel Configuration and Anchor Peer Configs for each organization.D. Genesis Block, Channel Configuration and Anchor MSP Configs for each organization.Answer: CExplanation:To create a network according to an organization's structure, and to bootstrap a channel, we will need togenerate the following artifacts: A genesis block, containing organization-specific certificates that serve toinitialize the Fabric blockchain. Channel configuration information. Anchor peer configurations for eachorganization. An anchor peer serves as a fulcrum within an organization, for cross-organization ledgersyncingusing the Fabric gossip protocol.Question 3Which Hyperledger tool would you select to invoke, deploy or query blocks, transactions and associateddata,network information (name, status, list of nodes), chain codes and transaction families, as well as otherrelevantinformation stored in the ledger?Options:A. Hyperledger QuiltB. Hyperledger CelloC. Hyperledger CaliperD. Hyperledger ExplorerAnswer: DExplanation:Hyperledger explorer: Hyperledger explorer, which was originally contributed by IBM, Intel, and DTCC, canview, invoke, deploy or query blocks, transactions and associated data, network information (name, status,listof nodes), chain codes and transaction families, as well as other relevant information stored in the ledger.Question 4https://www.certification-questions.com
Blockchain CBDHBlockchain services consists of three major components.What are they? (Select three.)Options:A. Consensus ManagerB. Distributed LedgerC. Peer to Peer ProtocolD. Reputation ManagerE. Membership ServicesAnswer: A, B, CExplanation:1. P2P Protocol is implemented over HTTP/2 standards and uses Google RPC. P2P components definemessages used by peer nodes, from point to point to multicast. 2. Distributed Ledger manages the worldstateand the transaction log in the blockchain. 3. Consensus Manager defines the interface between theconsensusalgorithm and the other Hyperledger components.Question 5The gossip data dissemination protocol performs which three functions? (Choose three.)Options:A. Manages peer discovery and channel membershipB. Disseminates ledger data across all peers on the channelC. Manages channel membership onlyD. Sync ledger state across all peers on any channelE. Sync ledger state across all peers on the channelF. Manages peer discovery onlyAnswer: A, B, EExplanation:Gossip Protocol The gossip data dissemination protocol performs three functions Manages peer discoveryandchannel membership Disseminates ledger data across all peers on the channel Syncs ledger state acrossallpeers on the channel.https://www.certification-questions.com
Blockchain CBDHReference: 0-alpha/gossip.htmlQuestion 6What Hyperledger sponsored tool is a new open-source application development framework, whichsimplifiesthe creation of Hyperledger Fabric blockchain applications, thus reducing the time and complexity ofdevelopment.The tool aims at helping users to create blockchain applications based on Hyperledger Fabric withoutneedingto know the low-level (Go Programming) details involved in blockchain networks?Options:A. Hyperledger QuiltB. Hyperledger ComposerC. Hyperledger ExplorerD. Hyperledger CelloAnswer: BExplanation:There is a new open-source application development framework, which simplifies the creation ofHyperledgerFabric blockchain applications, thus reducing the time and complexity of development. The tool aims athelpingusers to create blockchain applications based on Hyperledger Fabric without needing to know the low-level(GoProgramming) details involved in blockchain networks.Question 7The CA (Certificate Authority) in Hyperledger Fabric issues the certificates. These certificates are used foridentity validation and for transmission of encrypted data that only the owner (person, organization orsoftware)of a specific certificate is able to decrypt and read.What types of certificates are issued by the CA?Options:A. tcertB. ecertC. rootcerthttps://www.certification-questions.com
Blockchain CBDHAnswer: A, B, CExplanation:Rootcert, tcert and ecert. As The CA (Fabric CA by default) issues a root certificate (rootCert) to eachmember(organization or individual) that is authorized to join the network. The CA also issues an enrollmentcertificate(eCert) to each member component, server-side applications and occasionally end users. Each enrolleduser isgranted an allocation of transaction certificates (tCerts). Each tCert authorizes one network transaction.Question 8Hyperledger Composer has the following two main components.Options:A. Composer Framework and a Business Network ArchiveB. Composer Playground and a Business Network ConfigurationC. Composer Playground and a Business Network ArchiveD. Distributed Ledger and a Business Network ArchiveE. Distributed Ledger and Composer playgroundAnswer: CExplanation:There are two parts: 1. Business Network Archive which essentially captures the core data in a businessnetwork, including the business model, transaction logic, and access controls, the Business NetworkArchivepackages these elements up and deploys them to a runtime. Business Network Archive files are stored as".bna” files. AND 2. Composer Playground which is web-based tool allows developers to learn HyperledgerComposer, model out their business network (domain), test that network, and deploy that network to a liveinstance of a blockchain network. The playground keeps the development model in browser storage,allowingthem to be easily uploaded or downloaded.Question 9The Hyperledger Fabric framework is implemented on what programming environment?Options:A. C B. Node.jshttps://www.certification-questions.com

Hyperledger Fabric Hyperledger Fabric is the most notable blockchain project in the Hyperledger ecosystem. It features a ledger just like other blockchain technologies and also utilizes smart contracts. Hyperledger Fabric also allows all participants to manage their transactions like other blockchain applications. .
Hyperledger is used by more than half of top Forbes Blockchain 50 corporates and is the most widely used enterprise blockchain platform. Our Hyperledger developer certification program empowers you with the understanding the concepts of setting up Hyperledger fabric network and developing enterprise multi party applications through chaincode.
Hyperledger Fabric Documentation (v2.2) The open-source documentation for Hyperledger Fabric is a starting point for key concepts and the architecture of the Hyperledger Fabric blockchain network that you build using Managed Blockchain. As you develop your blockchain application, you can reference this document for key tasks and code samples.
Hyperledger Fabric, one of the umbrella projects of IBM, is an open-source, permissioned blockchain. Hyperledger Fabric blockchain differs from other blockchain in many ways. It makes use of execute-order-validate mechanism whereas other blockchain networks use order-execute logic. This helps Hyperledger Fabric e-ISSN : 0976-5166
Fabric Hyperledger is a BlockChain framework that fits our need. In this paper, we propose a security architecture based on the Fabric Hyperledger framework. We validate our approach first at a design level by running examples, then by showing some implemented function-alities. Index Terms—IoT, Blockchain, Fabric Hyperledger, NDN.

Walking is mainly on rough paths, tracks and grass, which may be muddy at times. There are two stiles and four kissing gates and some short steep slopes, but generally gently undulating. The walk starts close to Moor Park station on the Metropolitan line and ends at Hatch End station with trains to Euston and Harrow & Wealdstone. The highlights of this walk are the Old Furze Wood, the 97 .
