You currently on a conference call with an executive from a too big to fail bank. They are validating that they want to use Quorum or another enterprise blockchain. They specifically want to know what type of consensus algo it uses and what industry for the Quorum blockchain targets.

You are currently consulting with an organization that ships widgets overseas. They would like to implement a Hyperledger Fabric and would like to know about how to use cryptocurrencies with Hyperledger Fabric.What is the best answer?

If they need a native currency for their chain network, they can develop their own native currency with chaincode.

Hyperledger Fabric can be integrated with any crypto currency by using the proper APIs.

If they need a native currency for their chain network, they must use Ripple currency with chaincode.

If they need a native currency for their chain network, they must use Ethereum currency with chaincode.

Hyperledger Fabric does not support cryptocurrencies.

You have flown to NYC to have a discussion with a technical executive of a too big to fail bank. You are having a discussion about blockchain algos and the customer is asking what are some disadvantages of using a POW algo?

Large expenditures for computational power

Centralization of blockchain control

Only use case for computational power is blockchain

Large expenditures for computational power

What are two reasons that you would consider implementing a POW algo in your blockchain? (Select two.)

What matters is to have large computational power to solve the puzzles and form new blocks over having a financial stake.

PoW imposes some limits on actions in the network and therefore can thwart attacks better than other algos due to high cost

PoW imposes no limits on actions in the network and therefore can thwart attacks better than other algos due to high cost

The algo is energy efficient compared to POS and BFT

The algo is energy efficient compared to POS and DPOS

When a consensus algo is considered to be "pluggable modularityÂ», what does that mean?

Select an optimal algorithm for your networks

Select a specific API that manages the blockchain

What are two specific advantages of using Hyperledger Fabric? (Select two.)

Open Source Modular architecture

Allows components to be plug-and-play

Use any programming language available

Open Source Modular architecture

Allows components to be plug-and-play

Makes mining cryptos more efficient

When you are developing with Fabric Composer which of the following is true?

Decreases the time of development

Simplifies the development of applications

Simplifies the integration of client applications

Increases the time of development

In Hyperledger there are three distinct types of nodes.What are the three types of nodes? (Select three.)

Client Node: That initiates the transaction

Peer Nodes: Commits Transaction & keeps the data in sync across the ledger

Client Node: That initiates the transaction

Peer Nodes: Commits Transaction & keeps the data in sync across the ledger

Ordered: They are the communication backbones and responsible for the distribution ofthe transactions.

Chaincode Services uses Docker to host (deploy) the chaincode without relying on any virtual machine or computer language. What would be the main reason or best reason that Hyperledger chose containers over virtual machines?

Docker provides a secured, lightweight method to sandbox chaincode execution that is "locked down".

Docker provides a secured, lightweight method to sandbox chaincode execution that is not "locked down".

Docker provides a secured, lightweight method to sandbox chaincode execution that is not "locked down" but additional programming languages cannot be enabled.

Docker provides a secured, lightweight method to sandbox chaincode execution that is "locked down".

Docker is fully compatible with Hyperledger and Linux with an upgrade subscription.

Hyperledger can best be described as a ____________________?
