| Front | Back |
| How can Auto Scaling reduce AWS costs | By dynamically adjusting the number of running instances based on workload |
| How can Data Transfer Costs be reduced in AWS | Utilize AWS PrivateLink, peering, and placement groups to minimize cross-region and internet transfer expenses |
| How can Elastic Load Balancing (ELB) improve cost efficiency | Shares workloads across multiple instances and scales automatically to capacity needs |
| How can Lambda affect costs for a DevOps pipeline | Pay only for the actual compute time used during task execution |
| How can Managed NAT Gateway costs be optimized | Replace with EC2-based NAT for predictable, lower data volume |
| How do AWS Consolidated Billing and Organizations reduce costs | Combine and allocate usage across multiple accounts to maximize volume discounts |
| How do Savings Plans differ from Reserved Instances | Provide more flexibility across instances, regions, and instance families while still offering significant discounts |
| How does AWS Compute Optimizer help with cost efficiency | Provides recommendations for improving resource utilization across EC2 instances |
| How does AWS Spot Instances lower costs | By offering unused EC2 capacity at up to 90% discount compared to On-Demand prices |
| How does AWS Storage Gateway help optimize costs | Integrates on-premises applications with cloud storage to reduce infrastructure expenses |
| How does EC2 Auto Scaling with Spot Instances lower costs | Automatically integrates cost-efficient Spot Instances into your scaling groups |
| How does Elastic Kubernetes Service (EKS) help manage costs | Auto-scales Kubernetes worker nodes based on workload to optimize infrastructure costs |
| How does enabling EC2 Instance Termination Protection help | Prevents accidental cost increases due to misconfigured instance deletions |
| How does Standard Reserved Instances differ from Convertible Reserved Instances | Standard RIs are less flexible and offer higher discounts compared to Convertible RIs which can be modified during the contract period |
| How does the AWS Free Tier contribute to cost optimization | Allows experimenting with services at no cost up to certain limits for 12 months or always free for selected offerings |
| What are some tools for tracking AWS usage in real-time | AWS CloudWatch and third-party tools like Datadog or New Relic |
| What does the Service Quotas feature assist with | Managing resource limits and avoiding costly overprovisioning or throttling issues |
| What is a common strategy for optimizing EC2 usage | Rightsizing instances to better match workload requirements |
| What is a major benefit of using AWS Batch for compute workloads | Optimizes the execution of batch jobs by efficiently allocating resources |
| What is AWS Cost Explorer | A tool to visualize and analyze your AWS expenses and usage patterns |
| What is AWS Savings Plans | Flexible plans that offer cost savings in exchange for consistent usage of AWS services |
| What is AWS Trusted Advisor used for | Identifying cost optimization opportunities through specific service checks and recommendations |
| What is the advantage of using serverless architectures | Eliminates the cost of provisioning and managing servers by utilizing event-driven compute services |
| What is the benefit of enabling AWS CloudTrail for cost optimization | Tracks API usage and resource changes to identify inefficient or expensive patterns |
| What is the benefit of enabling Reserved Capacity in RDS | Ensures cost savings for relational databases by committing to a fixed capacity over time |
| What is the benefit of using S3 Intelligent-Tiering | Automatic tiering moves data to the most cost-effective storage tier based on access patterns |
| What is the cheapest storage tier in AWS S3 | S3 Glacier Deep Archive |
| What is the function of AWS OpsWorks in cost management | Simplifies application deployment and lifecycle management, reducing repetitive manual effort |
| What is the goal of rightsizing recommendations in AWS | To ensure resources match workload demands while minimizing costs |
| What is the purpose of AWS Budgets | Allows setting custom spending thresholds to monitor and control AWS costs |
| What is the purpose of Reserved Instances | To reduce costs up to 75% by committing to a long-term usage of AWS resources |
| What is the purpose of tagging resources in AWS | Enables cost allocation by categorizing expenses across departments, teams, or projects |
| What is the role of AWS Cost Anomaly Detection | Uses machine learning to alert users of unexpected cost or usage increases |
| What is the role of AWS Service Catalog in cost control | Ensures deployments adhere to organizational cost policies by providing pre-configured templates |
| What is the significance of regional pricing differences in AWS | Avoid deploying resources in higher-cost regions to optimize expenses |
| What is the use of Cost Allocation Tags | Attribute costs to specific resources, teams, or projects for better financial management |
| Which AWS pricing model is best suited for unpredictable workloads | On-Demand Instances |
| Why is it important to monitor unused resources in AWS | To avoid unnecessary charges for idle or orphaned services |
| Why is it important to use lifecycle policies with S3 | Automates moving data to lower-cost storage tiers over time |
About the Flashcards
Flashcards for the AWS DevOps Engineer Professional exam help students review essential AWS cost-management terminology, concepts, and practical strategies. This deck is designed for quick study and emphasizes the tools and metrics used to analyze spending, identify savings, and prevent unnecessary charges.
Cards cover pricing models and purchasing options (On-Demand, Reserved Instances, Savings Plans, Spot), compute and scaling tactics (rightsizing, Auto Scaling, Lambda, EKS, ELB), storage and lifecycle policies (S3 Intelligent-Tiering, Glacier Deep Archive, lifecycle rules), cost governance and tracking (Cost Explorer, Budgets, Cost Anomaly Detection, Trusted Advisor, CloudWatch), and organizational controls like tagging, Consolidated Billing/Organizations, Service Catalog, and Service Quotas.
Topics covered in this flashcard deck:
- Pricing models and plans
- Compute cost strategies
- Storage tiering & lifecycle
- Billing and monitoring tools
- Tagging and governance
- Data transfer optimization
