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.”

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.
Refer to the exhibit. An AI developer implements the above neural network architecture for handwritten digit recognition. The model achieves 85% training accuracy and 83% test accuracy. Which modification is most likely to improve training accuracy?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
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.

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.
