Prepare for the Security+ SY0-801 exam (CompTIA Security+ V8). In this lesson: hot, warm, and cold sites and platform diversity, redundancy (load balancing, clustering, autoscaling, and high availability), backups (retention, immutability, and restoration tests), testing and planning, and the recovery metrics RTO, RPO, MTTR, and MTBF, after a flooded server room. Includes three original practice questions.
Preview the topics
- Ashgrove wants a recovery site with power, network links, and some servers already installed, but it accepts that restoring the data from backups will take about a day. Which type of site is this?
- After a ransomware attack at another company, Ashgrove wants backups that cannot be changed or deleted until their retention period ends, even by someone who has stolen an administrator account. Which property is this?
- Ashgrove’s finance team says that the order system may lose, at most, fifteen minutes of orders after a failure, even if bringing the system back takes longer. Which metric does this define?
