Which of the following is NOT a feature of MongoDB Ops Manager?

MongoDB Ops Manager is designed to manage MongoDB deployments and includes several essential features aimed at enhancing operational efficiency. Among these features, automation plays a crucial role as it simplifies the process of deploying, configuring, and managing MongoDB clusters. Backup is another critical component, ensuring data safety through reliable backup solutions.

Query optimization pertains to how queries are executed within the database and is generally managed at the database engine level rather than through an operational management tool like Ops Manager. While Ops Manager facilitates monitoring and can provide insights that help improve performance, query optimization itself is not a feature directly provided by Ops Manager. Instead, it is the responsibility of the database developers and administrators to optimize their queries and indexes.

Data visualization, while an integral part of many analytics and monitoring tools, is not primarily a feature of Ops Manager. Instead, Ops Manager focuses on managing database operations rather than providing extensive visualization capabilities.

Thus, the correct answer highlights that query optimization is an operational feature that falls outside the specific functionalities offered by MongoDB Ops Manager.
