Exam Questions
Define Amazon EC2 regions and availability zones?
Availability zones are geographically separate locations. As a result, failure in one zone has no effect on EC2 instances in other zones. When it comes to regions, they may have one or more availability zones. This configuration also helps to reduce latency and costs.
What are AWS networking components? (Name all 3, for up to 300 points)
What are VPC security groups?
A security group is like a virtual firewall. It works much like a traditional firewall does. It consists of a set of rules that can be used to monitor and filter an instance's incoming and outgoing traffic in a Virtual Private Cloud (VPC) instance.

What is AMI?
AMI stands for Amazon Machine Image. It’s a template that provides the information (an operating system, an application server, and applications) required to launch an instance, which is a copy of the AMI running as a virtual server in the cloud. You can launch instances from as many different AMIs as you need.
With specified private IP addresses, can an Amazon Elastic Compute Cloud (EC2) instance be launched? If so, which Amazon service makes it possible?
Yes. Utilizing VPC makes it possible (Virtual Private Cloud).
What is the standard limit of security groups available in a VPC?
500, this can be changed by contracting AWS Support.
Define Snapshots in Amazon Lightsail?
The point-in-time backups of EC2 instances, block storage drives, and databases are known as snapshots. They can be produced manually or automatically at any moment. Your resources can always be restored using snapshots, even after they have been created. These resources will also perform the same tasks as the original ones from which the snapshots were made.
How many books are in the Harry Potter series?
7.
What is the difference between a Spot Instance, an On-demand Instance, and a Reserved Instance?
************* DAILY DOUBLE***************
Spot instances are unused EC2 instances that users can use at a reduced cost. When you use on-demand instances, you must pay for computing resources without making long-term obligations. Reserved instances, on the other hand, allow you to specify attributes such as instance type, platform, tenancy, region, and availability zone. Reserved instances offer significant reductions and capacity reservations when instances in certain availability zones are used.
How do you set up a system to monitor website metrics in real-time in AWS?
Amazon CloudWatch helps you to monitor the application status of various AWS services and custom events.
What is the difference between an EC2 and a VPC?
What is Amazon Athena?

Hardware Virtual Machine (HVM)
Paravirtualization (PV)
Paravirtualization on HVM
What are the main components of VPC? (I listed about 7, name 4.)
Elements of a VPC
Multiple Linux Amazon EC2 instances running a web application for a firm are being used, and data is being stored on Amazon EBS volumes. The business is searching for a way to provide storage that complies with atomicity, consistency, isolation, and durability while also increasing the application's resilience in the event of a breakdown (ACID). What steps should a solutions architect take to fulfill these demands?
AWS Auto Scaling groups can create an application load balancer that spans many availability zones. Mount a target on each instance and save data on Amazon EFS.
What is string theory?
String Theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interact with each other.
