Hyperledger blockchain frameworks reach consensus by performing two separate activities.What are the two activities? (Select two.)
Answer(s): B,C
Hyperledger business blockchain frameworks reach consensus by performing two separate activities:1. Ordering of transactions 2. Validating transactions by logically separating these activities, we ensure that any Hyperledger framework can work with any Hyperledger consensus module.
All of the following are key terms in Cryptography EXCEPT?
Answer(s): B
Cryptography is used in Blockchain to address the issues and concerns of privacy. Cryptography is the study of how to send information back and forth securely in the presence of adversaries. A cryptographic function is a function for encoding or encrypting data to protect the contents from others. The following components are the basis of a cryptographic function: The Secret: The data which we are trying to protect The Key: A piece of data used for encrypting and decrypting the secret The Function: The process or function used to encrypt the secret The Cipher: The encrypted secret data, output of the function The Secret and the Key are passed into the Function to create a Cipher.
The Hyperledger Project Framework of blockchains is meant for specific use cases for enterprise. Which blockchain includes a novel consensus algorithm, Proof of Elapsed Time (PoET)?
Answer(s): D
Hyperledger Sawtooth is a modular platform for building, deploying, and running distributed ledgers. Hyperledger Sawtooth includes a novel consensus algorithm, Proof of Elapsed Time (PoET), which targets large distributed validator populations with minimal resource consumption.
Which tool would you select to that would allow users to measure performance of a specific implementation with predefined use cases?
Answer(s): A
Caliper, a blockchain benchmark tool that allows users to measure performance of a specific implementation with predefined use cases, is in incubation status and was contributed by developers from numerous organizations.
What component on the blockchain maintains the "world state"?
Distributed Ledger manages the world state and the transaction log in the blockchain. The world state is defined as the state of all transactions on the Blockchain, where all nodes agree that all blocks on the Blockchain are at the same state. It implements three key attributes. It efficiently calculates the cryptographic hash of the entire dataset of each block. It efficiently transmits a minimal "delta" changes to the dataset, when a peer is out of sync and needs to "catch up". It minimizes the amount of stored data required for each peer to operate.

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).
