- A
Apply model compression techniques like pruning and quantization
Compression reduces model size and inference cost, and can also reduce training energy.
- B
Extend the number of training epochs to ensure convergence
Why wrong: More epochs increase total energy consumption.
- C
Train the model on a data center powered by renewable energy
Using renewable energy reduces the carbon footprint even if energy consumption is unchanged.
- D
Use energy-efficient hardware such as TPUs or low-power GPUs
Efficient hardware reduces energy consumption per computation.
- E
Increase the model size to achieve better accuracy faster
Why wrong: Larger models require more computation and energy, not less.

AI0-001 AI Governance and Ethics Practice Question
This AI0-001 practice question tests your understanding of ai governance and ethics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A research lab is training a large language model and wants to minimize its environmental impact. Which THREE practices are most effective for reducing the carbon footprint of model training?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply model compression techniques like pruning and quantization
Option A is correct because model compression techniques like pruning and quantization directly reduce the computational requirements of training and inference. Pruning removes redundant weights, and quantization reduces the precision of weights (e.g., from 32-bit to 8-bit), which lowers the number of operations and memory bandwidth needed, thereby decreasing energy consumption and carbon emissions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that 'more training' or 'bigger models' are inherently better for performance, but the trap here is that these choices increase energy use and carbon footprint, directly contradicting the goal of minimizing environmental impact.
Detailed technical explanation
How to think about this question
Pruning can be structured (removing entire neurons or channels) or unstructured (removing individual weights), with structured pruning often yielding better hardware acceleration. Quantization-aware training (QAT) allows the model to adapt to lower precision during training, minimizing accuracy loss while achieving up to 4x energy savings on specialized hardware like TPUs. In practice, combining pruning and quantization can reduce the carbon footprint of training a large model by 50-80% without significant performance degradation.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the AI0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
