Explanation:
The recovery point objective (RPO) sets and defines the amount of data an organization must have available or accessible to reach the predetermined level of operations necessary during a BCDR situation.
The recovery time objective (RTO) measures the amount of time necessary to recover operations to meet the BCDR plan. The recovery service level (RSL) measures the percentage of operations that would be recovered during a BCDR situation. SRE is provided as an erroneous response.

Explanation:
Cloud environments depend heavily on API calls for management and automation. Any vulnerability with the APIs can cause significant risk and exposure to all tenants of the cloud environment. Resource pooling and elasticity could both be impacted by insecure APIs, as both require automation and orchestration to operate properly, but automation is the better answer here. Redundancy would not be directly impacted by insecure APIs.

Explanation
The network utilized is not one of the key components of an encryption system architecture. In fact, a network is not even required for encryption systems or the processing and protection of data. The data, software used for the encryption engine itself, and the keys used to implement the encryption are all core components of an encryption system architecture.
