1. After the transaction that contains the delState("A") function is committed, what happens to the ledger and state database?

getstate("A") function returns the current state of the key "A".

The deleting transaction sets an empty value to the key "A" in the write set.

The state of the key "A" is removed from the state database, but its history remains in the ledger.

All transaction histories which updated the state "A" are deleted from the ledger.

11. What is the purpose of the ordering service in Hyperledger Fabric model?

To endorse transactions and update the world state.

To manage the identities of the participants in the network

12. What is the main purpose of certificates in Hyperledger Fabric?

Certificates are used solely in Transport Layer Security (TLS) protocols, providing the necessary keys.

Providing identity for different actors, helping with ledger consistency, authorization and Transport Layer Security (TLS).

Encrypting the stored ledger data in a way that certain data is visible only to certain organizations.

Certificates are certified digital documents making certain parts of the system transparent.

13. When executing queries on the ledger, what is the difference between simple and composite keys?

Simple keys and composite keys are not used when executing queries on the ledger.

Simple keys allow for more complex queries than composite keys.

Composite keys allow for more complex queries than simple keys.

Simple Keys and composite Keys function the same way when executing queries on the ledger
