**Question 1. Which type of blockchain allows only approved participants to read and write
transactions, making it suitable for consortium insurance projects?**
A) Public blockchain
B) Private (permissioned) blockchain
C) Hybrid blockchain
D) Sidechain
Answer: B
Explanation: Private (permissioned) blockchains restrict access to known entities, aligning with
consortium needs where insurers, brokers, and reinsurers collaborate securely.
**Question 2. In a Proof‑of‑Authority (PoA) consensus mechanism, what primarily determines
the right to create the next block?**
A) Amount of cryptocurrency staked
B) Computational power (hashrate)
C) Identity and reputation of validators
D) Random lottery selection
Answer: C
Explanation: PoA relies on a set of approved validators whose identity and reputation grant
them block‑creation authority, offering fast finality for high‑frequency insurance transactions.
**Question 3. Decentralized Identifiers (DIDs) enable which of the following capabilities for
policyholders?**
A) Centralized storage of personal data on insurer servers
B) Self‑sovereign control over identity credentials
C) Mandatory disclosure of all transaction history to regulators
D) Automatic generation of credit scores
Answer: B

Integration Officer CCIBIO Exam
Explanation: DIDs support self‑sovereign identity (SSI), allowing individuals to own, manage,
and present verifiable credentials without relying on a central authority.
**Question 4. Cross‑chain communication between an insurer’s private ledger and a broker’s
public chain is typically facilitated by:**
A) Smart contract duplication
B) Oracle networks
C) Interoperability protocols such as Polkadot or Cosmos IBC
D) Manual data entry
Answer: C
Explanation: Interoperability protocols like Polkadot or Cosmos Inter‑Blockchain Communication
(IBC) enable secure, trust‑less data transfer across heterogeneous blockchains.
**Question 5. Which oracle type is best suited for delivering real‑time weather data to trigger a
parametric crop insurance payout?**
A) Software oracle pulling from APIs
B) Hardware oracle with IoT sensors
C) Human oracle inputting data manually
D) Consensus oracle from multiple nodes
Answer: A
Explanation: Software oracles can fetch up‑to‑date weather metrics from trusted APIs, providing
the necessary data for automated parametric triggers.
**Question 6. A parametric travel insurance smart contract that pays out when a flight is
delayed more than two hours primarily relies on which data source?**
A) Passenger boarding pass scan
B) Airline’s flight status API via an oracle
, AIIM Certified Chief Insurance Blockchain
Integration Officer CCIBIO Exam
C) Manual claim submission by the traveler
D) Weather conditions at the destination airport
Answer: B
Explanation: The smart contract queries an airline’s flight status API through an oracle; if the
delay exceeds the threshold, the payout is automatically executed.
**Question 7. In the lifecycle of an on‑chain insurance policy, which smart contract function
typically handles policy renewal?**
A) claimSubmission()
B) endorsePolicy()
C) renewPolicy()
D) cancelPolicy()
Answer: C
Explanation: renewPolicy() is coded to check expiry, recalculate premiums, and extend coverage
automatically, ensuring seamless renewal on the blockchain.
**Question 8. Which programming language is most commonly used for developing smart
contracts on the Ethereum blockchain for insurance applications?**
A) JavaScript
B) Solidity
C) Python
D) Go
Answer: B
Explanation: Solidity is the native language for Ethereum smart contracts, widely adopted for
insurance product automation.

**Question 9. When performing a static analysis of a Solidity contract, which vulnerability is
most critical to detect for preventing unauthorized fund withdrawal?**
A) Reentrancy attack
B) Integer overflow
C) Timestamp dependence
D) Gas limit exhaustion
Answer: A
Explanation: Reentrancy allows an attacker to repeatedly call a withdraw function before the
state updates, leading to theft of funds; thus it is a top priority to detect.
**Question 10. The Ricardian Contract model bridges code and legal prose by:**
A) Storing only the source code on‑chain
B) Embedding a human‑readable legal agreement that hashes to the smart contract code
C) Using AI to translate code into legal language automatically
D) Requiring notarized signatures for every transaction
Answer: B
Explanation: Ricardian Contracts pair a legal document with a hash of the executable code,
ensuring that the on‑chain logic matches the off‑chain legal terms.
**Question 11. Shared ledgers for historical loss data primarily help underwriters to:**
A) Reduce data storage costs by deleting old records
B) Access a single source of truth for loss trends across carriers
C) Hide loss information from reinsurers for competitive advantage
D) Increase processing time for risk assessment
Answer: B
