Question 1
How does AWS Cloud computing help businesses reduce costs? (Select TWO.)
Correct : B, E
Reducing Costs with AWS Cloud:
Capacity Adjustment (B):
Elasticity: AWS allows you to scale your resources up or down based on demand, which means you only pay for what you use. This reduces the cost of over-provisioning resources.
Auto Scaling: Automatically adjusts compute capacity based on usage, ensuring cost efficiency.
Eliminating On-Premises Costs (E):
No Infrastructure Maintenance: By using AWS, businesses do not need to invest in physical infrastructure or handle maintenance, reducing both capital and operational expenditures.
Managed Services: AWS offers managed services that reduce the need for in-house technical staff to manage and maintain infrastructure.

Question 3
Which option is an environment that consists of one or more data centers?
Correct : B
Understanding Availability Zones (AZs): An Availability Zone is a distinct location within an AWS region that is engineered to be isolated from failures in other AZs.
Characteristics of Availability Zones:
Data Centers: Each AZ consists of one or more discrete data centers with redundant power, networking, and connectivity.
High Availability: AZs are designed for high availability, providing low-latency network connections to other zones in the same region.
Fault Isolation: They provide fault isolation and are used to deploy applications and services to ensure high availability and reliability.
Use Cases for Availability Zones:
Multi-AZ Deployments: For services like RDS, deploying in multiple AZs ensures fault tolerance.
Disaster Recovery: Setting up resources in multiple AZs helps in quick recovery from failures.
Load Balancing: Distributing traffic across AZs using Elastic Load Balancing ensures optimal performance and availability.

Question 4
A company wants to set up its workloads to perform their intended functions and recover quickly from failure. Which pillar of the AWS Well-Architected Framework aligns with these goals?
Correct : C
Understanding the Reliability Pillar: The Reliability pillar of the AWS Well-Architected Framework focuses on the ability of a system to recover from infrastructure or service disruptions, dynamically acquire computing resources to meet demand, and mitigate disruptions such as misconfigurations or transient network issues.
Key Concepts of Reliability:
Foundations: Ensure a solid foundation on which to build, including AWS account management, limits, and networking.
Change Management: Manage changes in automation to ensure systems remain reliable during modifications.
Failure Management: Design systems to detect failures and automatically recover from them.
How to Align with Reliability Pillar:
Implement Multi-AZ Deployments: Deploy applications across multiple Availability Zones to ensure fault tolerance.
Use Auto Scaling: Automatically adjust resources to maintain system performance during demand fluctuations.
Monitor and Respond: Implement monitoring and alerting mechanisms using services like CloudWatch to detect and respond to issues proactively.

Question 5
Which Amazon S3 storage class is MOST cost-effective for unknown access patterns?
Correct : D
Understanding S3 Intelligent-Tiering: S3 Intelligent-Tiering is designed to optimize costs by automatically moving data to the most cost-effective access tier based on changing access patterns. It is ideal for data with unknown or unpredictable access patterns.
Why S3 Intelligent-Tiering is Cost-Effective:
Automatic Tiering: Moves data between two access tiers (frequent and infrequent access) based on changing access patterns, optimizing storage costs without performance impact.
No Retrieval Fees: Unlike other storage classes, there are no retrieval fees in Intelligent-Tiering, making it cost-effective for data with unpredictable access patterns.
Monitoring and Automation: Automatically monitors access patterns and transitions data, reducing the need for manual intervention.
When to Use S3 Intelligent-Tiering:
Unpredictable Access Patterns: Ideal for datasets where the access frequency cannot be determined or changes frequently.
Cost Optimization: For organizations looking to minimize storage costs without sacrificing performance or requiring manual intervention to move data between tiers.
