Which of the following scenarios are examples of scaling an IT architecture vertically?
Resizing an EC2 instance type from a1.medium to a1.xlarge for more CPU and memory power Resizing an RDS instance type from db.r5.large to db.r5.2xlarge To scale vertically is to increase the specifications of a single AWS resource as needed.
Adding resources to your application as user demand grows is an example of which cloud concept?
Scalability
Scalability
As cloud has essentially limitless capacity, it allows you to expand out as needed.
How many Availability Zones does each Region have?
At least 2
You have an application load balancer for routing traffic from developers to the EC2 instance that contains a web application being put into operation. To prepare for the application going live for public use, you add an Auto Scaling Group and a second application load balancer to route web traffic from customers to the EC2 instance. The addition is an example of which of the following:
Scalability
Which of the following are principles of sound cloud design?

VMware Cloud on AWS allows companies to migrate and extend their on-premises VMware vSphere-based environments to AWS Cloud using Amazon EC2. Which of the following choices accurately classifies this deployment model?
Hybrid Hybrid deployments connect infrastructure and applications between cloud-based resources and existing resources that are not located in the cloud. VMware Cloud on AWS is an example of a hybrid deployment, since it involves the on-premises environments of VMware and the cloud-based services of AWS.
Types of cloud computing deployemnts
Hybrid Private Public
Which of the following are principles of sound design when it comes to performance efficiency?
Democratize advanced technologies. Use Serverless architectures. Deploy into multiple Regions to go global in minutes.
With AWS services, you can use as many resources as you need, as well as use them when you need them. Which of the following terms can be applied to this concept?
Disposable resources Temporary resources
Availability Zones
Distinct locations from within an AWS region that are engineered to be isolated from failures.
Which of the following best describes Availability Zones?
Distinct locations from within an AWS region that are engineered to be isolated from failures.
In AWS, you can stop or terminate instances when not in use. Which of the following concepts describes this capability?
Elasticity
Which of the following best describes the ability to scale computing resources up or down easily, while only paying for the resources used?
Elasticity
Which of the following are advantages of cloud computing?
Elasticity - you need not worry about capacity. Variable expense Agility - Decreasing the time to start new services
Trusted Advisor
Ensures cost optimization of your AWS account by eliminating unused, underutilized, and idle resources, which include EC2 instances, load balancers, EBS volumes, and elastic IP addresses.
Five Best Practices of AWS Trusted Advisor
Fault Tolerence Cost Optimization Performance Security Service Limits
Which of the following best describes a system that will remain operational even in the event of a component failure?
Fault-tolerant
Deploying your EC2 instances across multiple AZs will help address which Cloud Concept?
High Availability
Which of the following best describes a system that is always online — without the need for human intervention?
Highly Available
In AWS' Global Infrastructure, what are Edge Locations responsible for?
Hosting a Content Delivery Network called CloudFront
CloudFront is used to route users to the edge location that provides the lowest amount of time delay in delivering content. Which of the following terms describes this 'time delay'?
Latency
A mobile shopping list app needs to be able to add, delete, and update items on specific lists anytime a user desires. The backend for the app will run on Amazon EC2 instances with Auto Scaling to manage fluctuations in user demand. Many times, a user will perform maintenance on many list items in a single session. What design characteristic must be incorporated into the app for these requirements to be met?
Make sure the app doesn't need knowledge of previous transactions In order for horizontal scaling to be effective, you'll want to make sure the app doesn't store previous transaction or session information on specific EC2 instances. That way, any EC2 instance provisioned by Auto Scaling can process the request.
You have a mission-critical application which must be globally available at all times. Which deployment strategy should you follow?
Multi-Region
What type of placement group should you use to spread Amazon EC2 instances across logical partitions so that they don't share the same underlying hardware?
Partition
Which of the following is a Shared Control of the AWS Shared Responsibility Model?
Patch Management Awareness & Training
Which of the following does Amazon assure will happen when paying for AWS on an as-needed basis?
Redirecting focus to innovation and invention Reducing procurement complexity Enabling the full elasticity of business operations
Which of teh below is correct when looking at Regions, Availability Zones, Edge Locations and Datacenters?
Regions contain Availability Zones Availability Zones contain Data Centers
Which of the following are principles of sound design when it comes to reliability?
Stop guessing about your capacity requirements. Scale horizontally.
A telecommunications company has his hired you as a consultant to develop a business case for moving its IT applications and infrastructure to AWS. The company's leadership understands the agility value of the cloud, but the finance group is not interested in shifting capital expense to operating expense due to the company's tax structure. What will you include in the business case to attempt to satisfy everyone at the company?
Suggest that the company make reserved instance purchases and capitalize them Many companies capitalize reserved instance purchases, especially those with 3-year terms. Waiting for current infrastructure to fully depreciate will cause the company to miss the other cloud benefits that are available.
Elasticity
The ability to increase or reduce(SCALE) the number or capabilities of AWS resources when needed and only pay for resources used.
Which of the following statements is true of AWS Regions?
They are independent geographical areas They are composed of Availability Zones
