VPC Traffic Mirroring VPC Traffic Mirroring, as the name implies, allows you to duplicate network traffic from ENIs attached to instances so that the duplicated traffic can then be sent to third-party tools and services for traffic analysis and inspection. When configured, the duplicated traffic is sent to a target; this could be a Network […]

Important note The term weaker is used in this context to describe very simple decision trees. Although XGBoost is much more robust than a single decision tree, it is important to go into the exam with a clear understanding of what decision trees are and their main configurations. By the way, they are the base […]

Storage Components A storage component is the underlying device where the data is stored. This can include a magnetic hard drive, a solid-state drive, or a tape device. In terms of patching, the devices themselves may require occasional firmware updates (see the next section on firmware). Additionally, the software used by an operating system to […]
