   A university is building a model to predict student dropout rates. The administration wants the model to identify at-risk students early, but the faculty union is concerned about the model being used to evaluate teaching performance. The data available includes grades, attendance, and financial aid records. What is the first step the project team should take?

   • ARestrict access to the model so only the administration can see the results.
   • BStart building the model with the available data and present results to stakeholders later.
   • CCollect more data, such as student survey responses, to improve the model's accuracy.
   • DConduct a stakeholder meeting with administration, faculty, and students to define the model's purpose and boundaries.

   A retail chain is planning to build a demand-forecasting model. The sales team wants the model to predict weekly demand for each product, while the supply chain team needs daily predictions to manage inventory. The IT department has a budget for one model deployment. What should the project team do first?

   • ABuild the daily prediction model because it can be aggregated to weekly for the sales team.
   • BHold a meeting with sales and supply chain to agree on a single prediction frequency that satisfies both teams.
   • CBuild two separate models, one for each team, using the same data.
   • DAsk the sales team to accept daily predictions even though they asked for weekly.

   A transportation company is building a model to predict traffic congestion. The data sources include real-time GPS feeds from vehicles, historical traffic patterns, and weather data. The GPS feeds arrive every 5 seconds, while the weather data is updated hourly. The model must produce predictions every 10 minutes. What is the most important data velocity consideration?

   • AStore all raw GPS data in a data lake without processing it until the model is retrained.
   • BSlow down the GPS feed to match the hourly weather data update rate.
   • CUse only the historical traffic patterns and ignore the real-time GPS feeds.
   • DEnsure the system can ingest and process the 5-second GPS feeds without data loss.

   A retail company is training a recommendation model on 10 TB of clickstream data. The training job must complete within 24 hours, and the team has a limited budget. The data is stored in an on-premises NetApp AFF array, and the training will run on a small GPU cluster. The data scientists want to use a distributed training framework. What is the most important infrastructure consideration before starting?

   • AEnsure the storage system can deliver sufficient read throughput to keep the GPUs busy during training.
   • BVerify that the GPU cluster has enough VRAM to hold the entire 10 TB dataset in memory.
   • CMove the data to a cloud object store first so the training cluster can read it over the internet.
   • DConfirm that the network switches support at least 1 Gbps between the storage and the GPU nodes.

   A research lab is training a computer-vision model on 20 TB of high-resolution images. The training cluster has 16 GPUs, and the data is stored on a NetApp FAS storage system. The data scientists report that GPU utilization is only 40% during training. What is the most likely cause?

   • AThe storage system cannot deliver enough read throughput to keep the GPUs fed with data.
   • BThe GPUs are too powerful for the model, so they finish computations too quickly.
   • CThe model is too small, so it does not use the full capacity of the GPUs.
   • DThe network between the GPUs is too slow for distributed training.
