Question 2

A social media company uses a MongoDB Atlas cluster with multiple shards and replica sets to manage user data. They need to perform an upgrade from MongoDB version 4.2 to 4.4 with minimal disruption. During the upgrade, a primary election may occur, changing the primary node of a replica set. Which of the following actions should be excluded from their upgrade plan to ensure a smooth process?

Options :

A : Disable automatic elections during the upgrade process to prevent primary changes.

B : Upgrade the secondary nodes of each replica set before upgrading the primary nodes.

C : Notify all stakeholders about the maintenance plan and schedule.

D : Monitor the cluster-s health and replication lag during the maintenance process.

Answer: A

Question 3

A MongoDB Atlas administrator needs to move data from a dedicated instance to a new serverless instance. What should the administrator do to achieve this goal?

Options :

A : Download the dedicated instance backup and restore it with the MongoDB Compass tool.

B : Convert the data from the dedicated instance backup with the Relational Migrator and restore it into the serverless instance.

C : Use Live Migration to migrate the data from the dedicated instance to the serverless instance.

D : Restore the data from the backup of the dedicated instance into the new serverless instance.

Answer: D

Question 4

You need to ensure that your MongoDB Atlas cluster adheres to strict security protocols by managing database user access effectively. Which approach should you take to implement robust user management features?

Options :

A : Configure role-based access control (RBAC) and create custom roles for different user groups.

B : Enable database auditing to track user activities.

C : Create a single user account with read/write access for all employees.

D : Use the default admin user for all database operations.

Answer: A

Question 5

A MongoDB Atlas Administrator is tasked with ensuring that a restoration process is compatible with existing database versions across various cluster types: free, dedicated, and serverless. When planning a restore procedure for a dedicated cluster that has undergone several version upgrades, what must be considered to guarantee compatibility between the backup version and the cluster’s current version?

Options :

A : Ensure that the backup version is at least one major version lower than the cluster-s current version before performing the restore.

B : Verify that the backup was taken from the same MongoDB server version or newer compared to the version currently running on the cluster.

C : Only restore backups that are from the exact same MongoDB version, including the minor patch number, to avoid any compatibility risks.

D : Restore backups directly to the cluster regardless of the original version of the backup, as MongoDB Atlas automatically handles version compatibility.

Answer: B
