AWS Solutions Architect Deployment & Scalability

Question 1

Which AWS service is best suited for automatically scaling EC2 instances based on demand?

Accepted Answer

AWS Auto Scaling

Answer

AWS Auto Scaling automatically adjusts the number of EC2 instances in your application based on predefined metrics and conditions. This ensures that your application has the right amount of compute capacity to handle fluctuating demand, improving performance and availability. It also helps optimize costs by scaling down resources during periods of low usage.

Question 2

What AWS service allows you to distribute traffic across multiple EC2 instances?

Accepted Answer

AWS Elastic Load Balancer

Answer

AWS Elastic Load Balancer (ELB) automatically distributes incoming application traffic across multiple EC2 instances, improving application availability and fault tolerance. By spreading the load, ELB prevents any single instance from becoming a bottleneck and ensures that your application can handle varying levels of traffic. It also monitors the health of registered instances and routes traffic only to healthy ones.

Question 3

Which AWS service allows developers to deploy applications without managing infrastructure?

Accepted Answer

AWS Elastic Beanstalk

Answer

AWS Elastic Beanstalk is a Platform as a Service (PaaS) that simplifies the deployment and scaling of web applications and services. It handles the underlying infrastructure provisioning, such as EC2 instances, load balancing, and auto-scaling, allowing developers to focus solely on their application code. This abstraction significantly reduces operational overhead for infrastructure management.

Question 4

What AWS feature enables you to deploy infrastructure as code?

Accepted Answer

AWS CloudFormation

Answer

AWS CloudFormation allows you to define your AWS infrastructure as code using templates, which can be written in JSON or YAML. This enables you to provision and manage AWS resources in an organized, repeatable, and predictable manner. Infrastructure as Code (IaC) helps automate deployments, reduce manual errors, and version control your cloud environment.

Question 5

Which AWS service helps with deploying software updates in a controlled manner?

Accepted Answer

AWS CodeDeploy

Answer

AWS CodeDeploy automates software deployments to a variety of compute services, including EC2 instances, AWS Lambda, and on-premises servers. It helps release new features rapidly, avoid downtime during deployment, and handle the complexity of updating applications. CodeDeploy ensures controlled and consistent deployments across your environments.
