A hypervisor is a layer of software that runs directly on top of a physical server and provides a virtualization layer. It allows multiple virtual machines (VMs) to run on the same physical hardware, sharing the underlying resources such as CPU, memory, and storage. The hypervisor isolates the VMs from each other and provides a virtual machine monitor (VMM) that manages the virtual machines' access to physical resources. The VMM is responsible for managing the VMs' creation, configuration, and removal, as well as their access to the physical resources of the host system. T

Capacity is a management monitoring parameter that involves examining the amount of infrastructure resources used. This includes monitoring storage capacity, network bandwidth, CPU utilization, memory usage, and other resources. Capacity management is important for ensuring that the infrastructure has sufficient resources to meet the demands of the business or customers. It involves predicting future resource needs, identifying capacity bottlenecks, and optimizing resource utilization to avoid performance degradation or service disruptions. Reference: Section 2.2.2 Infrastructure Resource Monitoring, page 76.

Cyber recovery is a process of restoring critical data and systems in the event of a cyber attack. This goal of this process is to ensure that a copy of the data is always available, even if the original data has been corrupted or compromised. This can be done by isolating a copy of the data and keeping it separate from the original. This ensures that the data is always available should a cyber attack occur, allowing the business to quickly restore the original data and continue operations.

an FC frame consists of five parts: start of frame (SOF), frame header, data field, cyclic redundancy check (CRC), and end of frame (EOF). The SOF and EOF act as delimiters. The frame header is 24 bytes long and contains addressing information for the frame.

Signature-based IDPS uses a database that contains known attack patterns or signatures. Each signature is associated with a particular type of attack and the IDPS will look for those patterns in order to identify malicious activity. For example, if the signature in the database is associated with a buffer overflow attack, the IDPS will look for that particular pattern of attack in order to detect the attack.

HDFS - Presents a streaming interface to run any application of choice using the MapReduce framework.

A continuous data protection (CDP) is a system that backs up data on a computer system every time a change is made. CDP maintains a continuous journal of data changes and makes it possible to restore a system to any previous point in time.
