A data scientist is implementing a deep learning neural network model for an object detection task on images.The data scientist wants to experiment with a large number of parallel hyperparameter tuning jobs to find hyperparameters that optimize compute time.The data scientist must ensure that jobs that underperform are stopped.The data scientist must allocate computational resources to well-performing hyperparameter configurations.The data scientist is using the hyperparameter tuning job to tune the stochastic gradient descent (SGD) learning rate, momentum, epoch, and mini-batch size.Which technique will meet these requirements with LEAST computational time?Read More →

A consulting company was hired to assess security vulnerabilities within a client company’s application and propose a plan to remediate all identified issues.The architecture is identified as follows: Amazon S3 storage for content, an Auto Scaling group of Amazon EC2 instances behind an Elastic Load Balancer with attached Amazon EBS storage, and an Amazon RDS MySQL database.There are also several AWS Lambda functions that communicate directly with the RDS database using connection string statements in the code.The consultants identified the top security threat as follows: the application is not meeting its requirement to have encryption at rest.What solution will address this issue with the LEAST operational overhead and will provide monitoring for potential future violations?Read More →

A company hosts an application on Amazon EC2 that is subject to specific rules for regulatory compliance.One rule states that traffic to and from the workload must be inspected for network-level attacks.This involves inspecting the whole packet.To comply with this regulatory rule, a security engineer must install intrusion detection software on a c5n.4xlarge EC2 instance.The engineer must then configure the software to monitor traffic to and from the application instances.What should the security engineer do next?Read More →
