The CIO requested that add redundancies to ensure a network is available $99\mathrm{.}999\%$ of the time $(365$ days per year operation$).$ The issues need to be covered 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 $99\mathrm{.}999\%$ uptime

$$ Estimation of the maximum hours of downtime that the company can expect in a given year to support its $99\mathrm{.}999\%$ uptime requirement. Show your calculation work.

$$ Risk mitigation plan that takes into consideration these factors:

o Power failure

o Inclement weather conditions

o Single cable or conduit failure

o Internet connectivity

o Hardware failure $($network device, server$)$
