A nominal core count hides a memory constraint

A fictional customer compares two supported server configurations for an application with a measured memory-bandwidth bottleneck. One quote lists more CPU cores but has not documented its installed memory population or representative application results. The other includes the actual platform population rules, memory configuration, capacity reserves and a bounded workload measurement. A colleague proposes choosing solely by core count. Another asks for comparable evidence of the intended performance and support assumptions. This written exercise purchases and installs nothing. It asks the learner to distinguish a component headline from an end-to-end design result and to identify the configuration and workload evidence needed before an authorized technical recommendation.
