Linux Foundation Exam HFCP Topic 3 Question 31 Discussion

In Hyperledger Fabric, when a transaction that includes the delState('A') function is committed, it results in the removal of the state of the key 'A' from the current state database. However, the history of all transactions that have affected the key 'A' remains intact in the ledger. This operation ensures that while the current state reflects the deletion, the immutability and traceability of the ledger are preserved, allowing for auditability and verification of past states. Options such as setting an empty value to the key or altering the transaction history are not supported, as they would violate the principles of immutability and transparency central to blockchain technology. Therefore, the correct outcome of a delState('A') operation is that the current state of 'A' is deleted, but its transaction history remains accessible in the ledger.
