Explanation:
Option A is correct because the gcloud config set container/cluster prod command specifically sets the default cluster for the gcloud CLI to 'prod', ensuring all subsequent commands target this cluster without needing to specify it each time. Options B, C, and D are incorrect as they either perform different functions (B updates cluster properties) or involve non-standard methods (C and D use files not recognized by gcloud CLI for default cluster settings). For more details, refer to Google Cloud's documentation on managing clusters.
