You are a solutions architect who works at a large retail company that is migrating its existing infrastructure to AWS. You recommend that they use a custom VPC. When you create a VPC, you assign it to an IPv4 Classless Inter-Domain Routing (CIDR) block of 10.0.1.0/24 (which has 256 total IP addresses). How many IP addresses are available? (Select the best answer.) - ✔✔251
What is the difference between AWS regions and Availability Zones (AZ)? - ✔✔AWS Regions are a collection of data centers that are displayed as a section like us-east-1, they are physical locations. Resources have to be deployed in a region. An availability zone is a group of one or more data centers within a Region. These are logical groups of data centers (which may be located in the same complex or building), and appear to the user in AWS as us-east-1a , -1b, etc. Resources are added to a availability zone in a region when deployed, and resources that need to interact with each other should be kept in the same AZ. For fault tolerance, deploy a separate set of your resources / applications to a different zone or region.In summary - a region is made up of availability zones. Resources are deployed in an AZ inside a region.
What is the difference between the three Cloud Service Models -- IaaS, PaaS, and SaaS? - ✔✔Infrastructure as a Service is where the "hardware resources" are managed by the provider, and the customer must provision the resources, provide the OS image, application, etc.
Platform as a Service is where the operating system and environment are also managed by the provider, to where the customer needs to only install their own applications to interact with data.
Software as a Service is the most common for retail consumers, where the provider manages all backend aspects, and the customer is able to log in and interact with their data directly - no install or setup required.
What is the difference between a standard AWS region and a GovCloud region? - ✔✔A standard AWS region can have resources deployed by any customer. GovCloud is a specific region located in the PNW area (Oregon-Washington) that meets specific FedRAMP or other controlled unclassified information security guidelines for government & restricted industry customers (federal contractors, research groups). It is otherwise functionally equivalent to the commercial AWS regions, all products in commercial are supported in Gov with additional security.
The difference between the standard AWS region and a GovCloud region is the level of security and who is capable of accessing that particular region. As an ordinary citizen, you have the ability to choose which AWS region and which availability zone you want. AWS regions are open to the public and a multitude of people will be connected to the same region. A GovCloud region is used mostly by the U.S. government to deploy resources and share data. These regions are not available to the public. Unlike the AWS regions, customer access is restricted when considering the GovCloud region. You have to be a U.S. citizen in order to access the GovCloud regions.
What AWS region is the most recent to launch? Name a region that is scheduled to launch in the future. - ✔✔The AWS region that is the most recent to launch is Milan in Europe with a total of 3 availability zones. A region that is scheduled to launch in the future is Montreal in Canada.
What is the purpose of the AWS Simple Monthly Calculator and the AWS TCO calculator ? - ✔✔The purpose of the AWS Simple Monthly Calculator is to allow you to see the monthly cost of Amazon Web Services for you based on the applications and services that you use. You are also able to see what it will cost if you use any of the AWS resources. When using the AWS Simple Monthly Calculator, you put in the description, instances, usage and type to see how much it is going to cost you.The purpose of the AWS TCO calculator is to help you compare the on-premises costs of running your application with how much it would cost if you used AWS. By using the AWS TCO calculator you are able to see how you can save money and if it would be cheaper if you used AWS. When using the AWS TCO calculator, you plug in On-Premises and the AWS region you would use and then you put in the specific hardware configuration, type and amount of data storage you are using. Then, when you are done, you receive a report so you can see the costs for everything if you use AWS or if you use the On-Premises services.
What is the difference between the AWS Simple Monthly Calculator and the Total Cost Calculator - ✔✔The difference between the two is that the AWS Total Cost Calculator allows you to compare the prices between using AWS and using the on-premises servers and databases. The AWS Simple Monthly Calculator only tells you how much it would cost for using applications and services on AWS.
What is the purpose of a VPC and a NACL? - ✔✔The purpose of a VPC is to allow you to launch Amazon Web Services into a virtual network that you have created. This virtual private cloud is only for your account. This resembles a network that would be used in your own data center. The VPC is isolated from other virtual networks in the AWS Cloud.The purpose of a NACL is to act as a firewall for directing incoming and outgoing traffic in one or more subnets. It is an optional layer of security to your VPC.
What is the difference between an AZ and a VPC? - ✔✔a VPC is deployed in a region and can be available across multiple availability zones in that region. An AZ is a logical zone in a region that has some physical isolation from another
