A Sample Question, Answer Key, and Exam Tip from the actual book.

1. A company runs a web application with unpredictable traffic patterns. During off-peak hours, the application operates with minimal load, but during peak hours, the traffic spikes significantly. The company wants to reduce costs by avoiding over-provisioning while maintaining high availability and performance. Which strategy should they implement?

A. Configure EC2 Auto Scaling with a fixed baseline capacity supplemented by dynamic scaling during peak hours

B. Use Elastic Load Balancer with scheduled scaling policies to adjust capacity based on historical trends

C. Implement EC2 Spot Instances with lifecycle hooks to manage cost-effective scaling during high-traffic events

D. Configure Auto Scaling groups with dynamic scaling policies based on CPU utilization and custom CloudWatch metrics

Answer Key

1. Correct Answer: D

D (Correct): Configuring Auto Scaling groups with dynamic scaling policies based on CPU utilization and custom CloudWatch metrics ensures that EC2 instances automatically adjust based on actual workload demand. This reduces costs by avoiding over-provisioning during low-demand periods and scaling out efficiently during peak times.

A (Incorrect): Configuring Auto Scaling with a fixed baseline capacity supplemented by dynamic scaling sounds plausible but lacks the efficiency of dynamic scaling based solely on real-time metrics. The fixed baseline can lead to unnecessary costs during consistently low-traffic periods.

B (Incorrect): Using Elastic Load Balancer with scheduled scaling policies only accounts for historical traffic patterns. It does not respond dynamically to unexpected traffic spikes, making it less cost-effective and less resilient to real-time demand changes.

C (Incorrect): Implementing EC2 Spot Instances with lifecycle hooks can reduce costs, but it doesn’t address automatic scaling effectively. Spot Instances are also not reliable for critical workloads due to their potential for sudden termination.

Exam Tip: For the exam, study how Auto Scaling Groups (ASGs) automatically adjust EC2 instances based on demand using dynamic scaling policies, step scaling, and target tracking scaling. Learn the difference between scheduled scaling (for predictable traffic patterns) and dynamic scaling (which reacts to real-time metrics like CPU utilization, network traffic, or request count). AWS often tries to mislead by including EC2 Spot Instances, which are cost-effective but not always reliable due to possible terminations. Also, be careful with scheduled scaling policies, which only work well for known traffic patterns but do not react dynamically to unexpected demand surges. Understand how CloudWatch alarms trigger scaling actions, and study scaling cooldown periods, instance warm-up times, and Auto Scaling Group termination policies to ensure you can select the most efficient and cost-effective scaling approach in different scenarios.
