   A company is evaluating whether to set up a mining operation in a region with strict environmental regulations. They want to minimize the carbon footprint of their mining activity. Which approach is most effective?

   • ALocate the mining facility in a region with low electricity prices, regardless of the energy source.
   • BJoin a large mining pool to reduce the total energy consumed by the operation.
   • CUse the latest ASIC miners that offer the highest hash rate per watt of electricity consumed.
   • DUse older, cheaper hardware to reduce upfront costs and rely on the facility's existing cooling system.

   A small mining operation runs 20 GPU rigs. The operator wants to smooth out income variability and reduce the variance of reward payouts. Which approach should the operator take?

   • AIncrease the GPU core clock and memory clock settings to boost individual hashrate.
   • BSwitch to a cryptocurrency with a shorter block time to increase the frequency of block rewards.
   • CJoin a mining pool and configure the mining software to connect to the pool's stratum server.
   • DSet up a second mining node to double the effective hashrate of the operation.
