✍️ Sample NFT Questions & Answers
1. Which standard's balanceOf takes only an address and returns a count of owned tokens?
ERC-721 balanceOf(owner) returns how many tokens an address owns; ERC-1155 also needs a token ID.
2. Why might a developer prefer a payment-splitter contract as the EIP-2981 receiver?
Setting the receiver to a splitter contract lets a single royalty payment be divided among several beneficiaries.
3. A marketplace honoring EIP-2981 typically calls royaltyInfo at what point?
Compliant marketplaces query royaltyInfo at sale time to determine how much to pay the receiver.
4. What is a reentrancy risk when handling NFT purchases with ETH refunds?
An external call before updating state can let a malicious receiver re-enter and exploit stale balances.
5. Which is the most popular NFT marketplace?
OpenSea is widely recognized as the largest and most popular NFT marketplace globally. It supports a vast array of NFTs across multiple blockchains, offering a comprehensive platform for buying, selling, and discovering digital collectibles, art, and gaming items. Its extensive user base and wide selection make it a dominant force in the NFT ecosystem.
6. What is the time it takes for NFT transactions to settle?
NFT transactions typically settle almost instantly, designated as T+0. This means the transaction is finalized on the same day it is initiated, as soon as it is confirmed on the blockchain. This real-time settlement is a characteristic feature of blockchain technology, differing from traditional financial transactions that may take days.

What Practice Test Geeks adds beyond an AI chat for NFT
An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:
- A timed, full-length NFT mock exam — 50 questions in 60 minutes with a 70% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
- A fixed NFT question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable NFT cheat sheet you can print or save as a PDF.
- NFT flashcards built from the same question bank.
- Free NFT practice tests with the correct answer shown after each question.
