Your industrial company is implementing a custom deep neural network model developed with TensorFlow to enhance its quality control system. The model is tasked with identifying semi-finished products for discard based on images captured from production lines across various phases. To ensure the model's operational efficiency, you are required to monitor its performance and optimize its inference speed without compromising accuracy. The solution must be scalable across multiple production lines and comply with industry standards for data privacy. Considering these requirements, what is the most suitable solution for this scenario? (Choose two correct options)
