AWS Certified Machine Learning Engineer – Associate (MLA-C01) — Question 161

A company runs a neural network model and retrains the model when the performance degrades. The company uses a training job that uses Amazon SageMaker AI distributed data parallelism (DDP). The training job takes several hours to run.

The company wants to decrease the required time for the training job.

Which solution will meet this requirement?

Answer options

• A. Increase the number of epochs.
• B. Increase the number of neurons in the hidden layers.
• C. Increase the number of layers.
• D. Increase the number of instances.

Correct answer: D

Explanation

Increasing the number of instances allows the training job to utilize more computational resources, thereby reducing the time required for training. The other options, such as increasing epochs, neurons, or layers, may improve model performance but do not directly address reducing training time.
