Linux Foundation HFCP Sample Questions:

01. How does a transaction that fails endorsement differ from one that passes endorsement but fails validation at commit?
a) An endorsement failure is caught before ordering so nothing is recorded, while a validation failure at commit is kept in the block but flagged invalid.
b) Both failures are silently dropped because the peer discards them, so that when an auditor reviews the ledger no trace of either one remains.
c) Both an endorsement failure and a validation failure end up recorded in a block, and in each case the failure is simply marked as invalid for auditing.
d) Both failures are retried automatically until they succeed.
 
02. If a transaction is invalidated during commit validation, what happens to its chaincode event?
a) The event fires normally because events are tied to ordering rather than to commit validation.
b) The orderer resends the event later.
c) The event is still delivered, but it carries a flag telling listeners the transaction was invalid.
d) Its chaincode event is not delivered to any listener.
 
03. A client application that listens for chaincode events is restarted after being offline for a while, and it must not miss any events from blocks that committed while it was down.
Which capability of Fabric event listening makes this possible?
a) A listener can start from a specified block number, so after a restart it resumes from the last block it processed and still receives the events committed in between.
b) A restarted listener receives only events from blocks committed after it reconnects, so the earlier ones are lost.
c) Committed events are held in the world state until a listener reads them and clears them from the queue.
d) The ordering service buffers every undelivered event per client and resends them once the client reconnects.
 
04. With the Peer Gateway Service, how does the client's connection burden change when it submits a transaction?
a) The client must still open its own direct connection to each endorsing peer in the network.
b) The ordering service, not the gateway peer, is what collects endorsements before commit.
c) Using the Gateway means endorsement is skipped and the transaction goes straight to ordering.
d) The gateway peer gathers the required endorsements on the client's behalf, so the app connects only to that peer, not to every endorsing peer.
 
05. An application must send a transaction to the peers required by the chaincode's endorsement policy without hard-coding their addresses. How does the Gateway determine which peers to use?
a) The application must list the address of every endorsing peer in its own configuration.
b) The MSP routes the transaction to the right peers.
c) It uses service discovery to locate peers that satisfy the endorsement policy.
d) The ordering service decides which peers must endorse the client's transaction proposal first.
 
06. After a client submits a transaction through the Gateway, what does the gateway peer do before responding to the client?
a) It never reports the final commit status.
b) It waits until the transaction commits and returns the commit status to the client.
c) It returns once the orderer has received the transaction and queued it for ordering.
d) It returns to the client as soon as the endorsing peers have signed, before any ordering happens.
 
07. On the client's behalf, which actions does the Peer Gateway Service perform when a transaction is submitted?
(Choose three.)
a) Issue the client's X.509 identity with the MSP.
b) Gather the endorsements the chaincode's endorsement policy requires.
c) Run the consensus algorithm that orders transactions into blocks.
d) Wait for the transaction to commit and return its status.
e) Submit the endorsed transaction to the ordering service.
 
08. Several organizations already share a channel. A subset of them must keep one sensitive data field confidential from the other channel members, and the group does not want to maintain a separate ledger.
Which approach fits this requirement?
a) Encrypt the field inside the chaincode so that every channel member stores and keeps the ciphertext on the shared ledger.
b) Use a Private Data Collection so the data stays off the channel ledger, which carries only a hash.
c) Have the ordering service hide the field from the other members.
d) Create a new channel, giving the subset its own separate ledger and peers.
 
09. In a production Hyperledger Fabric network, a majority of the Raft ordering nodes become unavailable at the same time. What happens to the network while the majority is down?
a) The ordering service cannot order new transactions into blocks until quorum is restored, although peers can still serve reads of already-committed state.
b) Ordering continues normally as long as any single node is still running.
c) The network permanently loses all of its committed data.
d) The peers take over ordering and block sequencing, so the network stays fully available.
 
10. A client application issues many read-only queries and wants to send each one to a particular peer, such as a nearby peer or one chosen to spread read load.
Why is the application able to choose which peer handles each of these reads?
a) A query must run on every peer named in the endorsement policy, so the application cannot single one out.
b) An evaluate (query) runs on a single peer, so the application can direct it to one specific peer of its choosing.
c) A query is broadcast to all peers over gossip, and whichever peer answers first returns the result.
d) A query is ordered into a block, so the ordering service assigns it to a peer on the application's behalf.
