Quick Answer

The answer is to remove the dropout layer. Dropout is a regularization technique that randomly deactivates neurons during training to prevent overfitting, but when training accuracy is already low—85% in this case—it can actually hinder the model’s ability to learn the training data fully. By removing dropout, you reduce regularization, allowing the neural network to fit the training set more closely and directly increase training accuracy. On the CompTIA AI+ AI0-001 exam, this scenario tests your understanding of the trade-off between regularization and underfitting; a common trap is assuming dropout always improves performance, when in fact it can suppress accuracy if the model is not yet overfitting. A useful memory tip: “Dropout drops accuracy when training is weak—remove it to let the network speak.”

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

Remove the dropout layer

Removing the dropout layer reduces regularization, allowing the model to fit the training data better and increase training accuracy.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

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

  • Increase the dropout rate to 0.7

    Why it's wrong here

    Increasing dropout adds more regularization, which would likely decrease training accuracy.

  • Increase the number of filters in the first Conv2D layer

    Why it's wrong here

    More filters increase capacity but may not directly improve training accuracy; could lead to overfitting.

  • Add another dense layer before the output

    Why it's wrong here

    Adding layers increases complexity but may not significantly boost training accuracy if current capacity is sufficient.

  • Remove the dropout layer

    Why this is correct

    Dropout adds regularization; removing it can increase training accuracy, especially if the model is underfitting.

    Clue confirmation

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • 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.
