4. A new online server system has been introduced to monitor network flows in the cable modem testing area. The old system consisted of one assembly purchased from an outside vendor and boasted a 99% reliability rating. The old system is no longer manufactured. The new system is made up of three components, hooked up in series, and each component boasts a reliability of 95%. The testing area has been reporting downtime of about 15%. Cameron needs to explain why this is occurring and provide a "backup" plan to correct the situation and restore the entire system back up to the old systems reliability rating.
