Review data flows after each new managed-service integration. This option addresses a different situation (public cloud data residency gate), in which an application design uses a global SaaS data pipeline before the team maps national data transfer restrictions. It is not the best response here because synchronous write acknowledgment can be constrained by intersite latency and supported quorum behavior. The relevant diagnostic or acceptance evidence in this case concerns: a sustained write test exceeds the application response threshold during link variation.

Validate power-source labeling in commissioning checklists. This option addresses a different situation (dual power supply independence), in which each server has redundant PSUs but both cables connect to the same distribution unit. It is not the best response here because synchronous write acknowledgment can be constrained by intersite latency and supported quorum behavior. The relevant diagnostic or acceptance evidence in this case concerns: a sustained write test exceeds the application response threshold during link variation.

Regularly test recovery under a lost-production-credentials assumption. This option addresses a different situation (data backup separate administrative plane), in which a ransomware resilience design keeps backups on storage with the same production admin credentials and no isolation.

The relevant diagnostic or acceptance evidence in this case concerns: a partition rehearsal selects the documented surviving side without concurrent writes.

Object storage APIs and block devices provide different access semantics; a database filesystem cannot treat a generic object bucket as a raw disk.

The relevant diagnostic or acceptance evidence in this case concerns: a partition rehearsal selects the documented surviving side without concurrent writes.

Separate backup administration and maintain a protected restorable copy. This option addresses a different situation (data backup separate administrative plane), in which a ransomware resilience design keeps backups on storage with the same production admin credentials and no isolation.

The relevant diagnostic or acceptance evidence in this case concerns: a partition rehearsal selects the documented surviving side without concurrent writes.

Redesign oversubscription or traffic placement to meet required aggregate throughput. This option addresses a different situation (network uplink oversubscription), in which the storage network uses multiple 25 Gb adapters but only one shared 10 Gb upstream trunk carries aggregate traffic.

The relevant diagnostic or acceptance evidence in this case concerns: a partition rehearsal selects the documented surviving side without concurrent writes.
