AI-900 Practice Question: Describe Artificial Intelligence workloads and considerations

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  AI that writes farming blogs and social media content for agricultural businesses

  Why it's wrong here

  Generative AI models such as large language models can create marketing text, but writing farming blogs and social media content is an external communication task, not a precision agriculture function. Precision agriculture specifically uses real-time field data, satellite imagery, weather feeds, and machine learning to inform physical decisions like planting timing, nutrient application, and water use. Content generation never reads soil sensors or adjusts farm equipment, so this option cannot represent precision agriculture.

• ✓

  Crop yield prediction, pest detection, irrigation optimisation, and crop health monitoring using ML and vision

  Why this is correct

  This option directly matches precision agriculture because it combines supervised machine learning, computer vision, and IoT sensor data to optimize actual crop production. Yield prediction uses historical agronomic data and weather patterns; pest detection uses image classification on leaf photos; irrigation optimization uses soil-moisture models; and crop health monitoring uses multispectral vegetation indices like NDVI. These AI applications help farmers reduce water, fertilizer, and pesticide inputs while improving yield and sustainability.

• ✗

  Automating all farming tasks with AI-powered robots that replace farm workers

  Why it's wrong here

  While agricultural robotics is a real and emerging application of AI, precision agriculture is fundamentally an information and decision-support discipline, not a mandate to replace all human labor. Automated equipment and robots can perform some tasks, such as weeding or harvesting, but precision agriculture's core is data-driven optimization of inputs, monitoring, and management practices. Envisioning AI as replacing all farm workers overstates the technology and confuses operational automation with precision agriculture's focus on augmenting human agronomic decisions.

• ✗

  Using AI to trade agricultural commodity futures on financial markets

  Why it's wrong here

  Algorithmic trading of agricultural commodity futures belongs to financial AI, not precision agriculture, because it analyzes market prices, volatility, and economic indicators rather than field conditions. Precision agriculture applies ML and vision to the biophysical production system — soil, water, crops, pests — to improve yields and resource efficiency. Although both use machine learning, their data sources, objectives, and operational contexts are completely different.
