2. What are the types of key pair and who own it?
3. What is the minimum & maximum vCPU available in EC2 Instance?
4. What type of protocol used for Windows Operating system?
5. What is AMI?

1. An instance in AWS is the virtual server in AWS cloud. Instance type refers to the hardware configuration (or capacity) of the instance that includes components such as, vCPUs, memory
2. Two keys in keypair are public key and private key. Public key that is used for decryption is stored in AWS, where as Private key that is used for encryption is stored in the local or client system.
3. The minimum vCPU in an EC2 instance is 1, whereas the maximum can vary based on the instance type; As of now 192 vCPUs could be provisioned within a single instance in AWS.
4. Please elaborate the questions as it seems to be missing something specific.
5. AMI stands for Amazon Machine Image. This refers to the template OS and software configurations that are needed to boot the instance.

1. What is a Data center? How many DCs could typically be there within a single AZ? Are there any limitations to that?
2. How close is one AZ to other AZ within a region? What are the different factors considered while choosing the distance between each AZ within a region?
3. In how many locations in Africa, do AWS have regions?
4. Do you know why AWS regions mostly have 3 AZs within a region as a standard? What could be the strategy behind that?
5. What are Domain controllers in AZs? What do they do?

1.Datacenter is where enterprises or cloud service providers has their physical machines to provide their services over the internet.
2.AZ are in same region are physically separated within 10 to 100 kilometers, but they are geographically close enough to support low-latency communication and high availability.
3.Number of AWS Regions in Africa: 1 (Cape Town, South Africa) and Number of Availability Zones in that Region: 3
4.It protects against natural disasters or power outages affecting multiple AZs at once.
5.Its a active Directory Domain Controllers that are deployed across multiple AZs for high availability, authentication, and identity management.
