Refer to the exhibit. What is the solution?

⚠ Common exam trap

Oracle often tests the distinction between hyperparameter tuning (learning rate, epochs) and fundamental model capability (fine-tuning support), leading candidates to mistakenly choose a hyperparameter adjustment when the core issue is that the model cannot be fine-tuned at all.

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

Use a different base model that supports fine-tuning.

The exhibit indicates that the base model does not support fine-tuning, which is a prerequisite for adapting a large language model to a specific task or domain. Using a different base model that supports fine-tuning allows the model to be customized through supervised learning on task-specific data, enabling it to learn new patterns and improve performance. This is the correct solution because without fine-tuning capability, the model cannot be effectively adapted regardless of other hyperparameter adjustments.

Answer analysis

Option-by-option breakdown

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

  • Use a different base model that supports fine-tuning.

    Why this is correct

    The error indicates the base model does not support fine-tuning; switch to a supported model.

  • Change the learning rate.

    Why it's wrong here

    Learning rate is fine-tuning parameter but does not enable fine-tuning on an unsupported model.

  • Increase the training epochs.

    Why it's wrong here

    Epochs do not affect model support for fine-tuning.

  • Use a different compartment.

    Why it's wrong here

    Compartment does not affect model capabilities.
