Which of the following describes a cloud service provider's availability goals and redundancy architecture?

A Disaster Recovery Plan (DRP) outlines recovery procedures and RTO/RPO targets after a disruption, not the provider's underlying redundancy architecture.

A Business Impact Analysis (BIA) identifies critical business functions and the consequences of downtime, but does not describe technical architecture or redundancy design.

A technical design document captures the specific infrastructure architecture, including redundancy mechanisms (e.g., multi-zone replication, failover clusters) and availability SLAs that a cloud service provider implements. It serves as the authoritative record of how availability goals are engineered and achieved. DRP and BCP documents reference these goals but do not define the underlying architecture.

A Business Continuity Plan (BCP) broadly addresses how operations survive a disruption, but does not detail the technical redundancy architecture of a cloud provider.
