The CIO has reviewed the high-level design (Week 3 Assignment) and has requested that you add redundancies to ensure the network is available 99.999% of the time (365 days per year operation). The issues you need to account for are power failure, inclement weather conditions, single cable or conduit failure, Internet connectivity, networking hardware, and server failures.

For this assignment, you will prepare a presentation for the CIO that covers the changes to the design you have made to support the desired network reliability. Your presentation should include the following:

• High-level network design with added redundancy that supports 99.999% uptime
• Estimation of the maximum hours of downtime that the company can expect in a given year to support its 99.999% uptime requirement. Show your calculation work.
• Risk mitigation plan that takes into consideration these factors:
  • Power failure
  • Inclement weather conditions
  • Single cable or conduit failure
  • Internet connectivity
  • Hardware failure (network device, server)
