💡 Hint

Common Mistakes

Using unsupported engine names like 'docker' or 'nginx'.

Leaving the engine parameter empty.

The --engine parameter specifies the database engine type. For RDS, valid engines include mysql, postgres, etc. Here, mysql is correct.

Complete the code to specify the instance class for the RDS instance.

AWS

aws rds create-db-instance --db-instance-identifier mydb --db-instance-class [1] --engine mysql --allocated-storage 20

💡 Hint

Common Mistakes

Using EC2 instance types instead of RDS instance classes.

Choosing instance classes that do not start with 'db.'.

The --db-instance-class parameter defines the compute and memory capacity of the RDS instance. db.t2.micro is a valid small instance class for RDS.

Fix the error in the command to enable public accessibility for the RDS instance.

AWS

aws rds create-db-instance --db-instance-identifier mydb --db-instance-class db.t2.micro --engine mysql --allocated-storage 20 --publicly-accessible [1]

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

💡 Hint

Common Mistakes

Using non-boolean words like 'enable' or 'yes' instead of 'true'.

Omitting the parameter value.

The --publicly-accessible parameter expects a boolean value: true or false. Using 'true' enables public access.

4fill in blank

hard

Fill both blanks to specify the master username and password for the RDS instance.

AWS

aws rds create-db-instance --db-instance-identifier mydb --db-instance-class db.t2.micro --engine mysql --allocated-storage 20 --master-username [1] --master-user-password [2]

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

💡 Hint

Common Mistakes

Swapping username and password values.

Using insecure or empty passwords.

The --master-username sets the admin username, commonly 'admin'. The --master-user-password sets the password, here 'password123' as an example.

5fill in blank

hard

Fill all three blanks to create an RDS instance with a specific storage type, multi-AZ deployment, and backup retention period.

AWS

aws rds create-db-instance --db-instance-identifier mydb --db-instance-class db.t2.micro --engine mysql --allocated-storage 20 --storage-type [1] --multi-az [2] --backup-retention-period [3]

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

Dstandard

💡 Hint

Common Mistakes

Using 'gp2' instead of 'standard' when 'standard' is required.

Setting 'multi-az' to a non-boolean value.

Using invalid backup retention values like zero or negative numbers.

The --storage-type can be 'standard' for magnetic storage. --multi-az expects a boolean like 'true' to enable high availability. --backup-retention-period is the number of days to keep backups, here 7 days.
