Disaster recovery and high availability are areas of security planning that involve tools, policies, and procedures that ensure the availability and recovery of critical services and infrastructure in the event of a human-induced or natural disaster.
In this course, you'll explore high availability and disaster recovery concepts such as load balancing, multipathing, and network interface card teaming. You’ll learn about facilities and infrastructure support concepts including uninterruptible power supply, power distribution units, generators, HVAC, and fire suppression. Lastly, you'll explore redundancy and high availability concepts including cold, warm, and hot sites, as well as network device backup and restore states and configurations. This course is one of a collection of courses that prepares learners for the N10-008: CompTIA Network+ certification exam.
