What type of peer executes chaincode?

  1. Anchor peer
  2. Endorsing Peer
  3. Chaincode is executed by the client
  4. Ordered Peer
  5. Chaincode is not executed by a peer.

Answer(s): B

Explanation:

Endorsing Peer Endorser peer Peers can be marked as Endorser peer (i.e. 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 scalability of the network.

question 14 - run terraform import: this is the recommended best practice for bringing manually created or destroyed resources under terraform management. you use terraform import to associate an existing resource with a terraform resource configuration. this ensures that terraform is aware of the resource, and you can subsequently manage it with terraform.

i just took my oracle exam and let me tell you, this exam dumps was a lifesaver! without them, iam not sure i would have passed. the questions were tricky and the answers were obscure, but the exam dumps had everything i needed. i would recommend to anyone looking to pass their oracle exams with flying colors (and a little bit of cheating) lol.

22. if you need to make sure that one computer in your hot-spot network can access the internet without hot-spot authentication, which menu allows you to do this? answer is ip binding and not wall garden. wall garden allows specified websites to be accessed with users authentication to the hotspot
