Which capability of MongoDB Ops Manager allows for easy deployment, maintenance, and upgrade of the MongoDB environment?

The capability of MongoDB Ops Manager that facilitates easy deployment, maintenance, and upgrades of the MongoDB environment is Automation. This feature streamlines the management of MongoDB deployments by enabling automated processes for tasks such as provisioning, scaling, and configuration.

With automation, users can set up new MongoDB instances or clusters quickly and ensure that they are deployed consistently according to best practices. It reduces the time and effort needed for routine tasks, such as upgrades and maintenance, minimizing the chances of human error and enhancing the reliability of the environment. This capability is critical for organizations that require agility and efficiency in managing their database infrastructure to support the dynamic needs of their applications.

The other options, while important in their own right, do not directly contribute to deployment and upgrade processes. Monitoring is focused on real-time visibility into the performance and health of databases. Data Backup provides mechanisms for ensuring data resilience and recovery but does not directly impact deployment or maintenance processes. Configuration Management refers to maintaining the state and settings of systems but lacks the automation component that specifically addresses deployment and upgrades. Thus, Automation is the most relevant capability in this context.
