Networking: Route53, Amazon CloudFront, and VPC
2. How do the Availability Zone and Region relate to one another?
AWS regions, like the US-West 1 (North California) and Asia South, are distinct geographic regions (Mumbai). Availability zones, on the other hand, are the locations that are present inside the regions. These are often isolated zones that have the ability to duplicate themselves as needed.
3. Describe auto-scaling.
When there is a need, you can provision and launch new instances using the auto-scaling capability. You can automatically raise or lower resource capacity in response to demand.
4. What does CloudFront’s geo-targeting entail?
Businesses can display customized content to their audience based on their geographic location using the geo-targeting idea without modifying the URL. This makes it easier for you to generate content that is specifically tailored to the demands of a local audience.
5. What actions comprise a CloudFormation Solution?
The steps of a CloudFormation solution are as follows:
- Using JSON or YAML format, create a CloudFormation template or use an existing one.
- Code should be saved in an S3 bucket, which acts as a code repository.
- To call the bucket and build a stack using your template, use AWS CloudFormation.
- The services are provisioned one at a time by CloudFormation after reading the file and comprehending the services that are called, their order, and the connections between the services.
6. How can a system be upgraded or downgraded with almost no downtime?
The following migration steps can be used to update or downgrade a system with almost little downtime:
- Open EC2 console
- Choose Operating System AMI
- Launch an instance with the new instance type
- Install all the updates
- Install applications
- Test the instance to see if it’s working
- If working, deploy the new instance and replace the older instance
- You can upgrade or downgrade the system once it has been implemented with almost no downtime.
7. What are the methods and tools you may employ in AWS to determine whether you are overpaying and how to fix it?
By using the following resources, you can verify that you are paying the appropriate price for the resources you are utilizing:
- Check the Top Services Table
The cost management console’s screen displays the top five services by usage. This will reveal how much money you are shelling out for the concerned supplies.
- Cost Explorer
There are services called cost explorers that can assist you view and examine your consumption charges for the previous 13 months. A cost projection for the following three months is also available.
- AWS Budgets
You can then prepare a budget for the services. Additionally, it will let you determine whether the current plan fits your spending limit and the specifics of how you utilize the services.
- Cost Allocation Tags
This aids in determining which resource has been more expensive during a given month. To keep track of your AWS charges, it enables you to categorize your resources and cost allocation tags.
8. Is there a different tool outside the console that can be used to log into the cloud environment?
You can use the following to log into the AWS resources:
9. What tools are available to build a centralized logging solution?

The T2 Instances are designed to give the CPU a moderate baseline performance as well as the potential to burst to a greater performance when needed by the workload.
The T2 instances are cheap and are of the General Purpose instance type. They are typically employed in situations where CPU usage is inconsistent or infrequent for workloads.
64. What benefits does AWS IAM offer?
An administrator can grant granular access to a number of users and groups using AWS IAM. The numerous materials that have been generated may need to be accessible to different user groups and users at different levels. Using IAM, we can establish roles with certain access levels and assign roles to people.
Additionally, it provides Federated Access, which enables us to grant access to resources to users’ applications without having to first construct IAM Roles.
65. Describe Connection Drainage.
AWS’s Connection Draining feature enables us to handle current requests on servers that are being modified or decommissioned.
By activating this Connection Draining, we allow the Load Balancer to wait a certain amount of time before providing an outgoing instance any new requests in order to force it to complete its ongoing demands. If Connection Draining is not enabled, an instance will immediately terminate and all pending requests will be unsuccessful.
66. What does AWS’s “Power User Access” mean?
The owner of an AWS resource is the same as an administrator user. The Administrator User has access to create, modify, delete, and inspect resources in addition to granting other AWS users access.
A Power User is given Administrator Access, but not the authority to manage users and permissions. Although they are not able to grant access to other users, users with Power User Access can change, delete, view, and create resources.
CloudFormation Related AWS Interview Questions
67. What distinguishes AWS CloudFormation from AWS Elastic Beanstalk?
The following are some distinctions between AWS Elastic Beanstalk and AWS CloudFormation:
- You may provide and define all of the infrastructure resources that are present in your cloud environment with the aid of AWS CloudFormation. AWS Elastic Beanstalk, on the other hand, offers a setting that makes it simple to deploy and run applications in the cloud.

When you mistakenly go over your allotted number of elastic IP addresses or don’t have access to an EC2 AMI, this capability comes in useful.
Elastic Block Storage Related AWS Interview Questions
70. How can EBS be used to automate EC2 backup?
The procedures listed below should be used to automate EC2 backup using EBS:
To list the Amazon EBS volumes that are locally associated to the instance, get the list of instances and connect to AWS using the API.
List the snapshots for each volume and indicate the snapshot’s retention time. Make a snapshot of each volume later.
If the snapshot is older than the retention term, make sure to delete it.
71. What distinguishes EBS from an instance store?
EBS is a type of permanent storage that enables data restoration in the future. Data that is saved to the EBS is retained even when the EC2 instance expires. Instance Store, on the other hand, is temporary storage that is physically connected to a host computer. You cannot separate an instance from another and reattach it using an instance store. Data in an Instance Store is lost if any instance is stopped or terminated, in contrast to EBS.
72. If so, how can you backup EFS similarly to how you would backup EBS?
Yes, you can recover from accidental changes or deletion in Amazon EFS using the EFS-to-EFS backup mechanism. Take these actions:
Open the AWS Management Console and log in.
Select “Launch EFS-to-EFS-restore”
To choose a region, use the console’s navigation bar’s region selector.
Check the Select Template page to see if you selected the correct template.
Give your solution stack a name.
Review the template’s parameters and make any necessary changes.
73. How can you automatically erase outdated snapshots?

- You can specify specific character requirements, such as those for uppercase, lowercase, digits, and non-alphanumeric characters.
- When a user next signs in to AWS, you can request a password reset, impose automatic password expiration, and block the reuse of existing passwords.
- When the user has permitted the password to expire, you can instruct the AWS users to get in touch with an account administrator.
80. What distinguishes an IAM role from an IAM user?
The following two points distinguish the IAM role from the IAM user:
- An IAM user has permanent long-term credentials and is used to directly interact with the AWS services, whereas an IAM role is an IAM entity that defines a set of permissions for making AWS service requests.
- While the IAM user has complete access to all AWS IAM features, trusted entities, such as IAM users, apps, or an AWS service, assume roles in the IAM role.
81. What are AWS IAM’s controlled policies?
There are two different categories of managed policies: ones that you maintain and ones that AWS manages. They are IAM resources that use IAM policy language to convey permissions. In contrast to the IAM users, groups, and roles to which they are associated, you are able to create, amend, and administer them independently.
82. How does AWS IAM benefit your company?
IAM allows for:
- Manage IAM users and their access – AWS IAM offers multiple users protected resource access.
- Control federated user access – Without defining IAM roles, AWS enables you to grant applications and your employees secure access to the resources in your AWS account.
83. Does Amazon offer region-based services for all services?
No, not all of its services allow for usage that is location-specific. Most of the services, however, are region-specific.
84. What is EBS in AWS?
Elastic block storage is a type of storage system used to keep track of persistent data (EBS). EBS can be utilized with block-level storage volumes and EC2 instances for throughput- and transaction-heavy applications of any size.
