Question 1
Domain 4: Billing, Pricing, and Support
Under the AWS shared responsibility model, which of the following is the customer's responsibility regarding billing?
-
○ Ensuring the underlying infrastructure is secure
-
✓ Monitoring resource usage and costs
-
○ Generating monthly invoices
-
○ Applying volume discounts automatically
Answer:
B. Monitoring resource usage and costs
Under the shared responsibility model, AWS is responsible for the security of the cloud (infrastructure), while the customer is responsible for security in the cloud (their data, configurations, etc.). For billing, the customer is responsible for monitoring their resource usage and associated costs. AWS generates invoices (C) and applies discounts (D). Infrastructure security (A) is AWS's responsibility.
Question 2
Domain 4: Billing, Pricing, and Support
A company notices a sudden, unexpected increase in their AWS bill. Which AWS service can automatically detect and alert them to unusual spending patterns?
-
○ AWS Budgets
-
✓ AWS Cost Anomaly Detection
-
○ AWS Trusted Advisor
-
○ AWS Compute Optimizer
Answer:
B. AWS Cost Anomaly Detection
AWS Cost Anomaly Detection uses machine learning to monitor your spending patterns, detect unusual spend, and alert you via email or Amazon SNS. Budgets allows you to set threshold-based alerts but does not automatically detect anomalies. Trusted Advisor offers cost optimization checks, and Compute Optimizer recommends resource changes.
Question 3
Domain 4: Billing, Pricing, and Support
Which AWS service allows you to set up cross-account access so that a central team can view and manage costs across multiple AWS accounts?
-
○ AWS IAM
-
✓ AWS Organizations
-
○ AWS Resource Access Manager
-
○ AWS Cost Explorer with consolidated billing
Answer:
B. AWS Organizations
AWS Organizations allows you to consolidate multiple AWS accounts into an organization that you create and centrally manage. It enables consolidated billing, which provides a combined view of costs and usage across all accounts. While IAM (A) manages permissions, Organizations is the service specifically designed for account grouping and central cost management. AWS Cost Explorer (D) can show costs across accounts when consolidated billing is enabled via Organizations.
Question 4
Domain 4: Billing, Pricing, and Support
What is the main advantage of using Amazon EC2 Spot Instances over On-Demand Instances?
-
○ Guaranteed availability
-
✓ Lower cost
-
○ Reserved capacity
-
○ Free data transfer
Answer:
B. Lower cost
The primary advantage of Spot Instances is significantly lower cost (up to 90% discount) compared to On-Demand Instances. The trade-off is that they can be interrupted with short notice. They do not guarantee availability (A) or reserve capacity (C). Data transfer costs are the same as other EC2 instances (D).
Question 5
Domain 4: Billing, Pricing, and Support
A startup wants to experiment with a new AWS service without worrying about unexpected costs during the evaluation period. What AWS Free Tier benefit is designed for this scenario?
-

-
○ 12 Months Free offers
-
✓ Short-term Trials
-
○ AWS Activate credits
Answer:
C. Short-term Trials
