Check AWS Free Tier Usage with CLI

You want to check your AWS Free Tier usage using the AWS CLI. Which command will correctly show the current usage details for your account?

A aws free-tier describe-usage --period 2024-01

B aws ce get-cost-and-usage --time-period Start=2024-01-01,End=2024-01-31 --filter FreeTier=true

C aws billing get-free-tier-usage --start 2024-01-01 --end 2024-01-31

D aws ce get-free-tier-usage --time-period Start=2024-01-01,End=2024-01-31

💡 Hint

Use the AWS Cost Explorer (ce) commands to get free tier usage data.

The AWS CLI command aws ce get-cost-and-usage with appropriate filters is the correct way to retrieve free tier usage data for a specified time period. The command aws ce get-free-tier-usage does not exist.

A AWS Budgets

B AWS Trusted Advisor

❓ Troubleshoot

Troubleshoot Missing Free Tier Usage Data

You ran aws ce get-free-tier-usage but received an empty result. What is the most likely reason?

A Your account is not eligible for Free Tier benefits.

B The AWS CLI version is outdated and does not support this command.

C You did not specify the correct time period in the command.

D Free Tier usage data is only available in the AWS Management Console, not via CLI.

💡 Hint

Consider account eligibility and permissions for free tier data.

If your AWS account is not eligible for Free Tier (for example, it is older than 12 months or has used up the free tier), the command will return no data.

🔀 Workflow

Set Up Free Tier Usage Alert Workflow

Which sequence correctly describes the workflow to set up an alert for Free Tier usage exceeding 80%?

A 3,1,2,4

B 2,1,4,3

C 1,3,2,4

D 1,2,3,4

💡 Hint

Think about the logical order of creating, configuring, monitoring, and receiving alerts.

First, create the budget with threshold, then configure notifications, monitor the dashboard, and finally receive alerts when thresholds are crossed.
