In the spirit of doing that, here are some AWS interview questions and answers that will help you with the interview process. There are a number of different AWS-related questions covered in this article, ranging from basic to advanced, and scenario-based questions as well. For the IAM users, I created a policy that required MFA for specific actions, such as accessing sensitive resources or performing administrative tasks. After attaching the policy to the appropriate user groups, I guided each user through the process of activating their virtual MFA devices using either Google Authenticator or another compatible application. VPC — or Virtual Private Cloud — is used to create a virtual network in the AWS cloud.

However, instance store volumes do not persist beyond the life of the instance, meaning that any data stored on them will be lost if the instance is stopped or terminated. A storage system used to store persistent data is called elastic block storage (EBS). Block-level storage volumes and EC2 instances can be used with EBS for throughput- and transaction-intensive workloads of any scale.

Elasticity is the ability of a system to scale capacity up and down in response to changes in demand. To prepare better for your upcoming Cloud engineer interview, you can check our post on Google Cloud Interview Questions. The permissions it launches are the ones that decide which one of the AWS accounts can use the AMI when launching instances. Further, it requires a block device mapping for determining the volumes in the correct order to connect them to the instances when they’re launched. Likewise, when you want to kill a command or finish a command during on-going commands then you can prefer to use the Kill command.

A hybrid cloud combines the use of public and private clouds and on-premises infrastructure to achieve a balance of cost, performance, and security. AWS provides multiple security features and compliance programs to ensure the security of customer https://remotemode.net/become-an-aws-cloud-engineer/ data. These include security controls, compliance certifications, attestations, and a shared security responsibility model. GCP is often considered the cheapest provider of cloud computing services, though prices have leveled out over time.

To excel in the role, a cloud engineer must have a solid understanding of cloud computing technologies and practices.
