Question 1

A MongoDB Atlas administrator needs to create a new database user for a data analysis team working on a machine learning project. The goal is to grant the user permissions to read data from specific databases without compromising security or granting unnecessary access. Which approach should the Atlas administrator take to configure the new database user by using the Atlas UI?

Options :

A : Assign the user "clusterAdmin" role for administrative access.

B : Grant the user the role of "dbAdmin" for all databases in the cluster.

C : Create the user with the role "read" in the project-s specific database.

D : Assign the user the role of "readWriteAnyDatabase" in the project.

Answer: C

Question 2

Which two are valid optional security features that can be configured in MongoDB Atlas?

Options :

A : Field Level Encryption

B : Continuous Backup

C : IP Whitelisting

D : Auto-Sharding

Answer: A,C

Question 3

An organization is evaluating their MongoDB Atlas configuration to ensure high availability and data integrity across their distributed databases. They are currently using an M30 cluster tier and seek to understand the differences between the oplog and the minimum oplog window settings. Which statement correctly describes the difference between the oplog and the minimum oplog window in MongoDB Atlas?

Options :

A : The oplog is a MongoDB feature that allows for the replication of data across nodes, whereas the minimum oplog window specifies the minimum amount of time data must remain in the oplog before it can be overwritten.

B : The minimum oplog window is a recovery feature that determines the number of days a backup is retained, whereas the oplog is a log of all operations that modify the data in the databases.

C : The oplog records all write operations to a MongoDB database, while the minimum oplog window is the user-configurable setting that determines the size of the oplog.

D : Both the oplog and the minimum oplog window are metrics that indicate the current load on the database server, and neither is configurable.

Answer: A

Question 4

During a recent project implementation, you observed an unusual spike in the activity feed of your MongoDB Atlas cluster. To determine the cause, you decide to analyze the Activity Feed in depth. Which of the following entries in the Activity Feed would most accurately help you identify operations that might be impacting the performance of your cluster?

Options :

A : Real-time CPU and memory usage

B : Database user role changes

C : Queries that triggered alerts due to execution time

D : User login and logout events

Answer: C

Question 5

What two actions should an Atlas Administrator take to secure database user authentication in a MongoDB Atlas cluster?

Options :

A : Grant administrative privileges to all users by default

B : Allow login from any IP address to ensure accessibility

C : Use strong password policies for all database users

D : Disable two-factor authentication (2FA) for simplicity

E : Enable database auditing to monitor user activities

Answer: C,E
