Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the authentication mechanism when connecting to MongoDB.

MongoDB

mongo --username user --password pass --authenticationMechanism [1]

Drag options to blanks, or click blank then click option'

ANoAuth

BSCRAM-SHA-256

COAuth

DLDAP

💡 Hint

Common Mistakes

Using 'NoAuth' which disables authentication and is insecure.

Confusing LDAP with MongoDB's default authentication.

The SCRAM-SHA-256 mechanism is a common and secure authentication method used in MongoDB.

medium

Complete the code to create a user with SCRAM-SHA-1 authentication mechanism in MongoDB.

MongoDB

db.createUser({user: 'alice', pwd: 'secret', roles: ['readWrite'], [1]: ["SCRAM-SHA-1"]})

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'authMechanism' which is not recognized in this context.

Using 'mechanism' or 'authMethod' which are invalid keys.

The correct field to specify the authentication mechanism when creating a user is mechanisms.

3fill in blank

hard

Fix the error in the connection string to use the correct authentication mechanism.

MongoDB

mongodb://user:pass@host:27017/db?authMechanism=[1]

Drag options to blanks, or click blank then click option'

APLAIN

BMONGODB-X509

CSCRAM-SHA-1

DSCRAM-SHA-256

Attempts:

3 left

💡 Hint

Common Mistakes

Using SCRAM-SHA-1 which is less secure.

Using PLAIN without TLS which is insecure.

Using SCRAM-SHA-256 is recommended as it is more secure than SCRAM-SHA-1.

4fill in blank

hard

Fill both blanks to configure MongoDB to use X.509 certificate authentication.

MongoDB

mongo --host [1] --ssl --sslPEMKeyFile [2] --authenticationMechanism MONGODB-X509

Drag options to blanks, or click blank then click option'

Acluster0.mongodb.net

B/etc/ssl/mongodb.pem

Clocalhost

D/home/user/key.pem

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'localhost' as host when connecting to a remote cluster.

Using a wrong or missing PEM key file path.

The host should be the MongoDB cluster address, and the PEM key file is the certificate file path.

5fill in blank

hard

Fill all three blanks to create a user with LDAP authentication and assign the read role.

MongoDB

db.createUser({user: '[1]', roles: ['[2]'], [3]: ["PLAIN"]})

Drag options to blanks, or click blank then click option'

AldapUser

Cmechanisms

Dwrite

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'write' role instead of 'read'.

Using wrong key for authentication mechanism.

The user name is 'ldapUser', the role is 'read', and the authentication mechanism key is mechanisms with value ['PLAIN'] for LDAP.
