An enterprise security architect is reviewing infrastructure resilience mechanisms to ensure continuous availability and disaster recovery readiness. Match each high-availability control on the left with the operational failover behavior or risk mitigation on the right.
- Active-Active ClusteringDistributes processing loads across all online nodes simultaneously while maintaining real-time state synchronization.
- Dual-PDU Redundant Power WiringPrevents unexpected server shutdowns caused by upstream utility circuit breaker trips or feed failures.
- Geographically Dispersed Warm SiteProvides pre-installed infrastructure with delayed data restoration, accepting moderate recovery time objectives.
- Heartbeat-monitored Active-Passive FailoverKeeps a secondary appliance on standby, automatically promoting it to active status upon primary signal loss.
Cevap
Active-Active Clustering matches simultaneous load distribution across online nodes. Dual-PDU Redundant Power Wiring matches protection against upstream circuit breaker power feed failures. Geographically Dispersed Warm Site matches pre-installed infrastructure requiring data restoration. Heartbeat-monitored Active-Passive Failover matches promoting a standby node upon primary signal loss.
Active-Active clustering actively distributes live production traffic across all nodes. Dual-PDU power wiring mitigates power feed line and circuit breaker failures. A warm site maintains hardware readiness but requires periodic or manual data updates. Active-Passive failover relies on heartbeat signaling to promote a standby secondary node when the primary node stops responding.
