A developer wants to mine a cryptocurrency that is ASIC-resistant and can be mined effectively with consumer GPUs. Which hardware and software combination is most appropriate?

Use a high-end GPU with mining software that supports the algorithm, such as Ethash or RandomX.

Use a GPU with mining software that only supports the SHA-256 algorithm.

Use a CPU with mining software that only supports SHA-256.

Use an ASIC miner with firmware that can be flashed to support any algorithm.

A miner is using mining software that connects to a pool. The software displays a message that the pool has assigned a new block template. What does this mean for the miner?

The miner's software will automatically update its configuration to match the pool's new settings.

The miner's software will validate the transactions in the new block template.

The miner's hardware will start hashing the new block template, looking for a nonce that produces a valid block hash.

The miner will receive a payout for the previous block template.

A mining company is evaluating the environmental impact of its operations. They have access to hydroelectric power at a low cost, but the region has seasonal droughts that reduce power availability. What is the most sustainable approach?

Use the hydroelectric power when available and shut down operations during droughts.

Use a mix of hydroelectric and coal power to ensure continuous operation.

Relocate to a region with consistent fossil-fuel power to avoid downtime.

Invest in battery storage to store excess hydroelectric power for use during droughts.

A developer wants to mine a new cryptocurrency that is designed to be ASIC-resistant and favors decentralized participation. Which hardware choice aligns with the coin's design goal?

Consumer GPUs, because the algorithm is memory-hard and ASIC-resistant.

CPUs, because they are the most energy-efficient option.

FPGAs, because they offer a balance between flexibility and performance.

High-end ASIC miners to maximize hashrate.
