D you have built frequent checkpointing into the training process / minimize cost -> preemptible

For financial institutions, reliability and minimizing interruptions are crucial. While preemptible instances are cost-effective, they do come with the risk of being terminated unexpectedly, which might not be ideal for critical financial applications.

Follows same principle as #70

Preemptible v3-8 TPUs are the most cost-effective option for training large TensorFlow models. They are up to 80% cheaper than non-preemptible v3-8 TPUs, and they are only preempted if Google Cloud needs the resources for other workloads. In this case, the model is long-running and checkpointing is used. This means that the training process can be interrupted and resumed without losing any progress. Therefore, preemptible TPUs are a safe choice, as the training process will not be interrupted if the TPU is preempted. The other options are not as cost-effective.

Answer D

Frequent checkpoints --> Preemptible --> D

preemptible is the keyword to me
