AWS Cloud Practitioner Exam Questions | CLF - C02 | Tutorial - 08 | Tech India |

Summary

In this video, the host discusses essential questions for the AWS Certified Cloud Practitioner exam, focusing on key topics such as AWS IAM Access Analyzer, AWS Artifact for compliance reports, and IAM security best practices. The video also covers topics like cost responsibilities in AWS, elasticity in the cloud, and how to securely manage access with multi-factor authentication. Viewers are encouraged to engage with the content and prepare for their exam by understanding the core concepts of AWS services and security measures.

Takeaways

• 😀 AWS IAM Access Analyzer helps identify whether an S3 bucket or IAM role has been shared with an external entity, such as another AWS account or a public user.
• 😀 To obtain AWS compliance reports before migrating to the cloud, you can download the reports directly from AWS Artifact.
• 😀 When migrating an IT infrastructure to AWS, the cost of application software licenses is the customer's direct responsibility.
• 😀 Enabling Multi-Factor Authentication (MFA) for login is a key security best practice for AWS accounts.
• 😀 Avoid using the root user for administrative tasks in AWS. Only use it for tasks that are absolutely necessary.
• 😀 In AWS IAM, it's important to follow the principle of least privilege, providing users with only the permissions they need to perform specific tasks.
• 😀 Rotating credentials regularly is considered a security best practice and should not be avoided.
• 😀 Elasticity in cloud computing refers to the ability to right-size resources as demand changes, ensuring scalability.
• 😀 The pay-as-you-go billing model in AWS is not directly tied to the concept of elasticity, but helps in optimizing costs.
• 😀 The AWS cloud environment allows quick procurement of resources when needed, which is an important aspect of elasticity.
• 😀 AWS recommends minimizing broad permission grants and sticking to granular permissions for better security and control.

Q & A

Which AWS service helps in identifying whether an S3 bucket or an IAM role has been shared with an external entity?

The correct answer is AWS IAM Access Analyzer. This service helps in identifying and monitoring access policies to determine if an S3 bucket, IAM role, or any other AWS resources have been shared with external entities such as another AWS account, a public user, or any unknown third party.

How can AWS compliance reports be generated before migrating an environment to AWS?

The correct answer is to download the reports from AWS Artifact. AWS Artifact is a portal that provides access to various compliance reports, including certification attestations and other relevant documents.

What is the company's direct responsibility after migrating IT infrastructure to AWS?

The company's direct responsibility is the cost of application software licenses. AWS is responsible for the hardware infrastructure, power for AWS servers, and physical security of the data centers.

What is the security best practice for managing AWS identity and access management?

The best practice is to turn on Multi-Factor Authentication (MFA) for added security during the login process. Using the root user access keys for administrative tasks and granting broad permissions are not recommended security practices.

What is meant by elasticity in the cloud?

Elasticity refers to the ability to right-size resources as demand shifts. It allows resources to scale up when there is an increase in demand and scale down when demand decreases. This ensures that resources are available as needed without over-provisioning.

What is the significance of the 'pay as you go' billing model in cloud computing?

The 'pay as you go' billing model means that users only pay for the resources they actually use. This is not directly related to elasticity, but it allows organizations to optimize costs by scaling resources according to demand.

Why is it incorrect to use the account root user for administrative tasks in AWS?

Using the root user for administrative tasks is a bad practice because the root user has unrestricted access to all resources. It is recommended to create specific IAM users with the least privilege required for performing administrative tasks.

What does the principle of least privilege mean in AWS?

The principle of least privilege means granting users only the permissions they need to perform their tasks. For example, if a user needs permission to create an EBS volume, they should not have permissions to create EC2 instances or delete volumes.

What does the AWS IAM Access Analyzer help in determining?

AWS IAM Access Analyzer helps determine whether AWS resources like S3 buckets or IAM roles are shared with external entities. It is a tool to identify potential security risks by analyzing access policies.

What are the correct answers when asked about elasticity in the cloud, choosing two options?

The correct answers are: (1) The ability to right-size resources as demand shifts, and (2) How easily resources can be procured when needed. These options best define elasticity, which is about resource scalability and availability based on demand.
