ANSWERS

Get to know the AWS Certified Solutions Architect exam topics.

1. A: Using AWS CloudFront to cache content closer to end-users can significantly improve application performance. AWS CloudFront is a content delivery network (CDN) service that helps deliver content, such as web pages, images, videos, and other static or dynamic assets, to end-users with low latency and high data transfer speeds.
2. D: AWS global infrastructure is composed of various types of regions. These include Standard, Local, and GovCloud, but not Special.
3. C: Amazon DynamoDB is a NoSQL database service through Amazon Web Services (AWS) designed to provide fast/scalable storage for applications that require low-latency access to large amounts of structured and semi-structured data.
4. D: The AWS design principle "implement loose coupling" emphasizes the importance of building components and services that are decoupled and independent from one another. It promotes the design of systems where individual components can operate and evolve independently, without creating tight dependencies that hinder scalability, flexibility, and maintainability.
5. D: Global Accelerator uses the AWS global network to route traffic through the AWS edge locations closest to your users, reducing latency and improving application performance. It leverages the AWS global network backbone with high-speed, low-latency connections to ensure fast and reliable data transfer.
6. B: Using multiple availability zones (AZs) to deploy applications in AWS is highly recommended for ensuring high availability. Availability zones are distinct data centers within a geographic region that are engineered to be isolated from each other in terms of power, networking, and other infrastructure elements. Distributing an application across multiple availability zones can minimize the risk of single points of failure and increase the overall resilience and availability of an application.
7. C: Hibernation is a feature that allows you to pause and resume your EC2 instances while preserving the in-memory state.
8. A: Amazon EMR (Elastic MapReduce) is a managed big data processing service offered by Amazon Web Services (AWS). It simplifies the processing of large amounts of data using open-source frameworks such as Apache Hadoop, Apache Spark, and Presto.
9. B: The AWS Well-Architected Framework serves as a guide to evaluate architectures, identify areas for improvement, and align solutions with AWS best practices. It helps customers build resilient, secure, high-performing, and cost-effective solutions on AWS, enabling them to achieve their business goals effectively.
10. D: AWS Trusted Advisor helps with analyzing and optimizing resource usage by providing insights and recommendations based on AWS best practices. It examines AWS infrastructure and usage patterns to identify areas where it may be possible to optimize resource utilization, reduce costs, and improve performance.
11. C: According to the AWS shared responsibility model, both AWS and the customer share responsibility for securing data in transit between EC2 instances and other AWS services. AWS is responsible for providing a secure infrastructure and ensuring the security of the AWS network and services. Customers are responsible for implementing appropriate security measures and configurations to secure the data in transit within their applications and between their EC2 instances and other AWS services.
12. D: Spot instances are a purchasing option provided by Amazon Web Services (AWS) that allow you to bid on unused EC2 (Elastic Compute Cloud) instances. The pricing is determined by a dynamic bidding process, where you specify the maximum price you are willing to pay per hour for the instance and, if the spot price falls below your bid price, your instance will be provisioned, and you will pay the current spot price. This is typically at a significantly lower price compared to on-demand instances but the availability of spot instances depends on the unused capacity in the AWS cloud.
13. A: Amazon Aurora is a fully managed relational database engine provided by Amazon Web Services (AWS). It is compatible with MySQL and PostgreSQL and is designed to deliver high performance, scalability, and durability for online transaction processing (OLTP) workloads. OLTP applications involve frequent, small, and fast database transactions and OLTP databases need to support concurrent access from multiple users and ensure high throughput and low latency for transactional operations.
14. B: The AWS design principle "Prepare for failure" emphasizes the importance of anticipating and managing failures proactively in order to enhance system resilience and mitigate the impact of potential disruptions. This principle recognizes that change is inevitable and emphasizes the need to manage changes effectively within a system.
15. B: The purpose of the cooldown period in a Step Scaling policy with Amazon Web Services (AWS) is to temporarily suspend further scaling actions after a change has been made. It serves as a time buffer during which additional scaling actions are prevented, allowing the newly applied changes to stabilize and have an effect on the system.
