Practice - 5 Tasks

1fill in blank

easy

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

AWS

rds_instance = {"DBInstanceClass": "[1]"}

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

Adb.t3.micro

Bdb.large

Cdb.xlarge

Ddb.m5.24xlarge

💡 Hint

Common Mistakes

Selecting a large instance class increases cost unnecessarily.

Using an instance class not supported by RDS.

The db.t3.micro instance class is a low-cost option suitable for small workloads, helping to minimize RDS costs.

medium

Complete the code to enable Multi-AZ deployment for high availability, which affects pricing.

AWS

rds_config = {"MultiAZ": [1]

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

A"true"

B"false"

Ctrue

DFalse

💡 Hint

Common Mistakes

Using string values instead of boolean.

Disabling Multi-AZ when high availability is needed.

Setting MultiAZ to true enables high availability but increases cost.

hard

Fix the error in the storage type to select a cost-effective option.

AWS

storage_config = {"StorageType": "[1]"}

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

Bgp3

Cio1

Dgp2

💡 Hint

Common Mistakes

Choosing io1 which is expensive and high performance.

Using gp2 or gp3 which cost more than standard.

The standard storage type is the most cost-effective but slower option compared to gp2 or io1.

4fill in blank

hard

Fill both blanks to configure backup retention and storage allocation for cost control.

AWS

backup_config = {"BackupRetentionPeriod": [1], "AllocatedStorage": [2]

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

B30

C20

D100

💡 Hint

Common Mistakes

Setting backup retention too high increases cost.

Allocating excessive storage wastes money.

Setting BackupRetentionPeriod to 7 days limits backup costs. Allocating 20 GB storage keeps storage costs low.

5fill in blank

hard

Fill all three blanks to configure RDS instance with cost-saving options: instance class, storage type, and Multi-AZ.

AWS

rds_settings = {"DBInstanceClass": "[1]", "StorageType": "[2]", "MultiAZ": [3]

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

Adb.t3.micro

Btrue

Cstandard

Ddb.m5.large

💡 Hint

Common Mistakes

Selecting large instance classes or expensive storage.

Using string 'true' instead of boolean true for MultiAZ.

Using db.t3.micro and standard storage reduces costs. Setting MultiAZ to true adds availability but increases price.
