____________is supposed to be the constant cost of network resources/utilization in the Ethereum blockchain?What is the constant?
Answer(s): C
Gas is supposed to be the constant cost of network resources/utilization. You want the real cost of sending a transaction to always be the same, so you can’t really expect Gas to be issued, currencies in general are volatile. So instead, we issue ether whose value is supposed to vary, but also implement a Gas Price in terms of Ether. If the price of ether goes up, the Gas Price in terms of ether should go down to keep the real cost of Gas the same.
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?
Answer(s): A
If you really need a native currency for your chain network, you can develop your own native currency with chaincode. One common attribute of native currency is that some amount will get transacted (the chaincode defining that currency will get called) every time a transaction is processed on its chain.

Is it possible to access the blockchain via an Ethereum Node?
True You can interact with the blockchain using RPC via HTTP POST requests. You can find out more about the JSON-RPC API here. Although you can use RPC to communicate with a local node you can also use it to hook up with a remote node. To send requests to the local node we address them to http://127.0.0.1:8545 (Geth exposes the RPC service on port 8545).
