An enterprise uses a shared business operations platform supporting manufacturing sites across several continents.

The two design qualities represented by the requirements are Availability and Performance .

Availability (D) is the dominant requirement because each manufacturing site must continue providing its critical local production functions even when connectivity to headquarters is lost. The architecture therefore needs to eliminate inappropriate WAN dependencies and provide sufficient local compute, storage, networking, and service redundancy so that a WAN or remote-site failure does not cause the business service itself to become unavailable. VMware infrastructure design uses redundancy, clustering, and fault-domain separation specifically to maintain service availability during component or connectivity failures. Broadcom ' s VCF guidance similarly associates sufficient cluster redundancy with satisfying availability requirements.

Performance (E) is also explicitly represented because the customer identifies degraded order-processing response during periods of high traffic. Performance is concerned with throughput, latency, resource contention, and maintaining acceptable response characteristics as demand changes. Broadcom notes that excessive network latency can degrade workload performance and recommends minimizing latency for stable operation during high-demand periods. Network I/O controls can likewise protect critical traffic during contention.

Recoverability concerns restoration after failure rather than continuous operation during a connectivity outage. Manageability and Security remain general architectural concerns but are not the primary qualities expressed in this scenario.
