Which two options are true regarding ATP database capabilities?

The correct choice regarding ATP (Autonomous Transaction Processing) database capabilities is the ability to scale storage up or down. This feature is particularly important for users who need flexibility in managing their database resources. In ATP, storage can be adjusted to meet changing demands, allowing users to optimize their costs and performance based on their requirements.

This capability supports dynamic workloads, meaning that as the data volume grows, users can increase their storage capacity without downtime or significant manual intervention. Likewise, if there is a decrease in usage or storage needs, one can reduce the storage allocations, allowing for cost efficiency.

The other options do have limitations based on the architecture and design of ATP. For example, while modifying the number of pluggable databases aligns with Oracle's multitenant architecture, it is not a feature offered in the same way as scaling storage. Understanding these dynamics helps users make informed choices when working with OCI and its database services.
