Which of the following are advantages of the AWS Cloud? (Select TWO.)
AWS manages the maintenance of the cloud infrastructure & AWS manages capacity planning for physical servers
AWS is responsible for security of the AWS Cloud as well as capacity planning and maintenance of the AWS infrastructure. This includes physical infrastructure such as data centers, servers, storage systems, and networking equipment.
The ability to horizontally scale Amazon EC2 instances based on demand is an example of which concept?
Elasticity
Elasticity is the ability to dynamically adjust the capacity of a service or resource based on demand. Scaling can be vertical (e.g. increase instance size) or horizontal (e.g. add more EC2 instances).
Which AWS service provides a quick and automated way to create and manage AWS accounts?
AWS Organizations
AWS Organizations is a web service that enables you to consolidate your multiple AWS accounts into an organization and centrally manage your accounts and their resources. The AWS Organizations API can be used to create AWS accounts and this can be automated through code.

How are AWS Lambda functions triggered?
Events
AWS Lambda lets you run code as functions without provisioning or managing server. Lambda-based applications (also referred to as serverless applications) are composed of functions triggered by events.
Which tool can be used to provide real time guidance on provisioning resources following AWS best practices?
Trusted Advisor
Trusted Advisor is an online resource that helps to reduce cost, increase performance and improve security by optimizing your AWS environment. Trusted Advisor provides real time guidance to help you provision your resources following best practices.
When performing a total cost of ownership (CO) analysis between on-premises and the AWS Cloud, which factors are only relevant to on-premises deployments? (Select TWO.)
Hardware procurement teams & Facility operations costs
Facility operations and hardware procurement costs are something you no longer need to pay for in the AWS Cloud. These factors therefore must be included as an on-premise cost so you can understand the cost of staying in your own data centers. Database administration, operating system licensing and application licensing will still be required in the AWS Cloud.
How does “elasticity” benefit an application design?
By automatically scaling resources based on demand
Elasticity refers to the automatic scaling of resources based on demand.
What is the benefit of using fully managed services compared to deploying 3rd party software on EC2?
Reduced operational overhead
Fully managed services reduce your operational overhead as AWS manage not just the infrastructure layer but the service layers above it. Examples are Amazon Aurora and Amazon ElastiCache where the database is managed for you.

Which of the following are architectural best practices for the AWS Cloud? (Select TWO.)
Deploy into multiple Availability Zones & Design for fault tolerance
It is an architectural best practice to deploy your resources into multiple availability zones and design for fault tolerance. These both ensure that
if resources or infrastructure fails, your application continues to run.
