In support of disaster recovery objectives, a third party agreed to provide 99.999% uptime. Recently, a hardware failure impacted a perimeter firewall, without service degradation. Which of the following resiliency concepts was most likely in place?
Redundancy refers to having backup systems, devices, or components in place so that if one fails, the other can take over without causing a disruption in service. In this case, the firewall failure did not result in service degradation, which suggests that there was a redundant system (perhaps a secondary firewall or failover mechanism) that took over, ensuring continued operation.
