Sample EC-Council CBP Practice Questions

Try these sample questions to test your EC-Council CBP exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which cryptographic hash function is used to compute Bitcoin block hashes?

A.MD5

B.SHA-1

C.SHA-256

D.RIPEMD-160 only

Explanation: Bitcoin uses double SHA-256 to compute block headers and transaction IDs. RIPEMD-160 is used in address generation (after SHA-256). MD5 and SHA-1 are insecure and are not used in Bitcoin.

2What is a Merkle tree primarily used for in a blockchain?

A.To compress private keys

B.To efficiently and securely verify the integrity of large sets of transactions

C.To replace digital signatures

D.To increase block size

Explanation: A Merkle tree hashes pairs of transactions up to a single Merkle root stored in the block header, allowing efficient and tamper-evident verification of inclusion (Merkle proofs) without downloading all transactions.

3Which signature algorithm does Bitcoin and Ethereum use for transaction signing?

A.RSA-2048

B.ECDSA over the secp256k1 curve

C.Ed25519

D.DSA

Explanation: Bitcoin and Ethereum both use ECDSA over secp256k1. Ethereum is migrating some operations to BLS for staking, but standard transaction signing remains ECDSA secp256k1. RSA is not used; Ed25519 is used by Solana and others.

4Which consensus algorithm does Bitcoin use?

A.Proof of Stake

B.Proof of Work

C.Practical Byzantine Fault Tolerance

D.Proof of Authority

Explanation: Bitcoin uses Proof of Work (PoW) with the SHA-256 mining puzzle. Ethereum migrated from PoW to Proof of Stake at The Merge in September 2022. PBFT and PoA are used in permissioned chains.

5In which year did Ethereum complete The Merge to Proof of Stake?

A.2020

B.2021

C.2022

D.2023

Explanation: Ethereum completed The Merge from Proof of Work to Proof of Stake in September 2022, dramatically reducing Ethereum's energy consumption (estimated >99.9% drop).

6How does the Bitcoin network handle the issuance of new coins over time?

A.Inflation rate is fixed at 5% per year

B.Block reward halves approximately every 210,000 blocks (~4 years)

C.Coins are minted by a central authority

D.Total supply increases proportionally with hash rate

Explanation: Bitcoin's block subsidy halves every 210,000 blocks (~4 years). The April 2024 halving cut the subsidy from 6.25 to 3.125 BTC per block. Total supply is capped at 21 million.

7What was the Bitcoin block subsidy after the April 2024 halving?

A.6.25 BTC

B.3.125 BTC

C.1.5625 BTC

D.12.5 BTC

Explanation: The April 2024 halving cut the block subsidy from 6.25 BTC to 3.125 BTC per block. The next halving (2028) will reduce it to 1.5625 BTC.

8Which Bitcoin scaling layer enables fast micropayments off-chain via payment channels?

A.Liquid Network

B.Lightning Network

C.Stacks

D.Rootstock

Explanation: The Lightning Network is a Layer 2 payment channel network on Bitcoin enabling instant, low-fee micropayments. Liquid is a federated sidechain, Stacks adds smart contracts, Rootstock is an EVM-compatible sidechain.

9Which transaction model does Ethereum use?

A.UTXO

B.Account-based

C.DAG

D.Stateless rollup

Explanation: Ethereum uses an account-based model where balances and contract state are stored per account. Bitcoin uses the UTXO (Unspent Transaction Output) model.

10What is the EVM in Ethereum?

A.A scaling layer

B.A virtual machine that executes smart contract bytecode deterministically across all nodes

C.A consensus algorithm

D.A wallet standard

Explanation: The Ethereum Virtual Machine (EVM) is a Turing-complete, deterministic virtual machine that executes smart contract bytecode. EVM compatibility lets chains like Polygon, BNB Chain, Avalanche C-Chain, and Arbitrum reuse Ethereum tooling.
