A security architect is establishing high availability guidelines for enterprise infrastructure. Which architectural control specification best matches each resilience technology?
- NIC TeamingCombines multiple physical network adapters into a single logical interface to provide link-level fault tolerance.
- Geographic DispersalProvisions system components across geographically distinct facilities to maintain operations during wide-area disaster events.
- Active-Passive ClusteringDirects application traffic to a primary operational node while maintaining an idle secondary node that assumes processing upon failure.
- Multipath I/O (MPIO)Configures redundant physical communication paths between host bus adapters and storage arrays to prevent storage access failure.
Cevap
NIC Teaming matches adapter-level link aggregation; Geographic Dispersal matches distribution across geographically separate facilities; Active-Passive Clustering matches a primary active node with an idle standby node; Multipath I/O matches redundant physical paths between server hardware and storage arrays.
Each high-availability control is mapped to its appropriate architectural scope: NIC Teaming operates at the network interface layer, Geographic Dispersal mitigates site-level operational risks, Active-Passive Clustering manages compute failover using a dedicated standby node, and Multipath I/O ensures continuous storage fabric availability.
