In Hyperledger Fabric, there are three types of peer nodes depending upon the assigned roles.What are three types? (Choose three.)
Answer(s): B,C,G
So not all peer nodes are same. There are different types of peer nodes with different roles in the network: Endorser peer Anchor peer Orderer peer Endorser peer Peers can be marked as Endorser peer (Endorsing peer). Upon receiving the "transaction invocation request" from the Client application the Endorser peer Validates the transaction. Check certificate details and roles of the requester. Executes the Chaincode (Smart Contract) and simulates the outcome of the transaction. But it does not update the ledger. At the end of the above two tasks the Endorser may approve to disapprove the transaction. As only the Endorser node executes the Chaincode (Smart Contract) so there is no necessity to install Chaincode in each and every node of the network which increases the scalibility of the network. Anchor peer Anchor peer or cluster of Anchor peers is configured at the time of Channel configuration. Just to remind you, in Hyperledger Fabric you can configure secret channels among the peers and transactions among the peers of that channel are visible only to them. Anchor peer receives updates and broadcasts the updates to the other peers in the organization. Anchor peers are discoverable. So any peer marked as Anchor peer can be discovered by the Orderer peer or any other peer. Orderer peer Orderer peer is considered as the central communication channel for the Hyperledger Fabric network. Orderer peer/node is responsible for consistent Ledger state accross the network. Orderer peer creates the block and delivers that to all the peers. Orderer is built on top of a message oriented architecture. There are two options are currently available to implement Orderer peer: Solo: Suitable for development. Single point failure. Solo should not be used for the production ready network. Kafka: Production ready Hyperledger Fabric network uses Kafka as the Orderer implementation. Kafka is a messaging software that has high throughput fault tolerant feature.
What certificate is granted an "allocation" of transaction certificates to each user?
Answer(s): C
Each enrolled user is granted an allocation of transaction certificates (tCerts).
Chaincode with Hyperledger Fabric can be written in what development languages? Select All that apply.
Answer(s): A,B,C
The advantages of using Hyperledger Fabric include which of the following?
Answer(s): A
Hyperledger Fabric has a modular component structure and an extensible plug and play framework
In regards to Fabric blockchain blocks. The structure of a "block header" consists of three sections when it is written. (Select three.)
Answer(s): B,C,D
Let's have a closer look at the structure of a block. It consists of three sections Block Header This section comprises three fields, written when a block is created. Block number: An integer starting at 0 (the genesis block), and increased by 1 for every new block appended to the blockchain. Current Block Hash: The hash of all the transactions contained in the current block. Previous Block Hash: A copy of the hash from the previous block in the blockchain.

nice tip and well documented
i need the exam
please upload
prepping for fsc exam
pd1 with great experience
@t it seems like azure service bus message quesues could be the best solution
helpful to check your understanding.
question 128 the answer should be static not auto
more comments here
great support to appear for exams
useful dumps
making progress
q31 answer should be d i think
is this real?
q10: c and f are also true. q11: this is outdated. you no longer need ownership on a pipe to operate it
good questions with simple explanation
admin guide (windows) respond to malicious causality chains. when the cortex xdr agent identifies a remote network connection that attempts to perform malicious activity—such as encrypting endpoint files—the agent can automatically block the ip address to close all existing communication and block new connections from this ip address to the endpoint. when cortex xdrblocks an ip address per endpoint, that address remains blocked throughout all agent profiles and policies, including any host-firewall policy rules. you can view the list of all blocked ip addresses per endpoint from the action center, as well as unblock them to re-enable communication as appropriate. this module is supported with cortex xdr agent 7.3.0 and later. select the action mode to take when the cortex xdr agent detects remote malicious causality chains: enabled (default)—terminate connection and block ip address of the remote connection. disabled—do not block remote ip addresses. to allow specific and known s
very inciting
question 5, it seems a instead of d, because: - care plan = case - patient = person account - product = product2;
it look like real one
i am taking oracle fcc certification test next two days, pls share question dumps
i need dumps
its time to comptia sec+
question 35 has an answer for a different question. i believe the answer is "a" because it shut off the firewall. "0" in registry data means that its false (aka off).
helpful content
oracle 19c is complex db
helpful for practice
support team is fast and deeply knowledgeable. i appreciate that a lot.
helpful questions
thanks for question
the software is provided for free so this is a big change. all other sites are charging for that. also that fucking examtopic site that says free is not free at all. you are hit with a pay-wall.
i need exam questions nca 6.5 any help please ?
just took the comptia cybersecurity analyst (cysa+) - wished id seeing this before my exam
very helpful
