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?

12. You are attempting to offer a service in a specific area, but the service is not present there. Why is this occurring, and how can it be resolved?

Not every location has access to every Amazon AWS service. When Amazon first introduces a new service, not all regions receive it right away. They begin modestly and then spread to other areas. Therefore, if a certain service is missing from your region, it probably hasn’t yet been published there. However, you can change to the closest region that offers the services if you want to use the service that is not currently offered.

13. How do you configure an AWS system to track website metrics in real-time?

You may monitor the status of numerous AWS services and custom events with the aid of Amazon CloudWatch. It aids in keeping track of:

14. What are the various forms of virtualization available through AWS, and how do they differ from one another?

In AWS, there are three main categories of virtualization:

  • Hardware Virtual Machine (HVM)
    All of the virtual computers on this completely virtualized hardware function independently of one another. The root block device of your image contains a master boot record that is executed to start these virtual machines.
  • Paravirtualization (PV)
    The PV AMIs are started by the bootloader Paravirtualization-GRUB. The menu-specified kernel is loaded by the PV-GRUB chain.
  • Paravirtualization on HVM
    Operating systems can benefit from the storage and network I/O made available by the host thanks to PV on HVM.

15. Name a few AWS services that are not region-specific.

23. Will the primary and backup RDS launch in the same availability zone?

No, standby instances are started in a different availability zone from the primary, creating two physically distinct infrastructures. This is so because preventing infrastructure failure is the sole goal of backup instances. As a result, in the event that the primary instance fails, the backup instance will aid in data recovery.

Advanced AWS Interview Questions

24. What distinguishes a Reserved Instance from an On-Demand Instance and a Spot Instance?

Spot instances are extra EC2 instances that can be used by users at a discounted price.

You must pay for computing resources without entering into a long-term commitment while using on-demand instances.

On the other hand, reserved instances let you select details like instance type, platform, tenancy, location, and availability zone. When using instances in specific availability zones, reserved instances offer significant discounts and capacity reservations.

25. In the event that the RDS instance replica is not elevated to the status of the master instance and the relational database engine routinely crashes as a result of increased traffic to your RDS instances, what would you do?

For handling huge amounts of traffic as well as creating manual or automatic snapshots to recover data in the event that the RDS instance fails, a larger RDS instance type is necessary.

26. What does “changing” in Amazon EC2 mean to you?

Customers now have the option to switch from the existing “instance count-based limitations” to the new “vCPU Based constraints” in order to make limit administration simpler. As a result, utilization is calculated using the number of vCPUs when launching a variety of instance types dependent on demand.

27. What does Amazon Lightsail define as a snapshot?

Snapshots are the point-in-time backups of EC2 instances, block storage disks, and databases. At any time, they can be created manually or automatically. Even once they are made, your resources can always be recovered using snapshots. The functions carried out by these resources will be identical to those of the initial resources used to create the snapshots.

AWS Scenario Related Questions

28. Your application is running on an EC2 instance. You must lessen the load on your instance if the CPU use reaches 80%. What method do you employ to finish the task?

When an EC2 instance’s CPU use exceeds 80%, it can be done by setting up an autoscaling group to deploy more instances. Additionally, traffic can be distributed among instances by creating an application load balancer and designating specific EC2 instances as target instances.

29. Several Linux A web application for a company is operating on Amazon EC2 instances, and data is being saved on Amazon EBS volumes. The company is trying to find a solution to offer storage that satisfies the requirements for atomicity, consistency, isolation, and durability while also enhancing the application’s resilience in the case of a malfunction (ACID). What actions ought a solutions architect to do to satisfy these requirements?

An application load balancer that spans many availability zones can be created using AWS Auto Scaling groups. Each instance should mount a target and save data to Amazon EFS.

61. What do RTO and RPO in AWS stand for?

The Recovery Time Objective, or RTO, is the longest period of time your company or organization is willing to wait for a recovery to be finished following an outage. RPO, or Recovery Point Objective, on the other hand, is the maximum amount of data loss that your business is ready to take as measured in time.

62. Which among Snowball, Snowball Edge, and Snowmobile is the best choice if you need to move a lot of data?

To move large amounts of data into and out of a certain AWS region, AWS Snowball essentially acts as a data transit solution. AWS Snowball Edge, on the other hand, adds extra computational capabilities in addition to offering a data transfer option. You can move up to 100 PB of data with the exabyte-scale migration service called snowmobiling.

63. What exactly are T2 instances?

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.
  • The infrastructure requirements of numerous application types, including legacy applications and current enterprise apps, are supported by AWS CloudFormation. AWS Elastic Beanstalk, on the other hand, works in tandem with developer tools to support you in managing the lifecycle of your applications.

68. What components make up an AWS CloudFormation template?

AWS CloudFormation templates are text files with YAML or JSON formatting that contain the following five components:

  • Template parameters
  • Output values
  • Data tables
  • Resources
  • File format version

69. What transpires if a resource in a stack cannot be effectively created?

The CloudFormation automatically rolls back and terminates all resources generated using the CloudFormation template if the resource in the stack cannot be created. 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?

Here is how to automatically delete previous snapshots:

Take snapshots of the EBS volumes on Amazon S3 in accordance with protocol and industry best practices.
To manage all the snapshots automatically, use AWS Ops Automator.
You are able to do this to make, copy, and remove Amazon EBS snapshots.

  • You can require users to add at least one number or special character to their passwords, or you can specify a minimum length requirement.
  • 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?
