CLF-C02 Exam Dumps - AWS Certified Cloud Practitioner

To follow the principle of least privilege, the company should create an IAM user with only programmatic access since the access is limited to AWS CLI and SDKs, not the Management Console. Additionally, a custom IAM policy granting specific Amazon RDS permissions should be created and attached to this user to restrict access solely to necessary actions. Providing programmatic access only ensures adherence to security best practices by limiting access to the required interfaces.

Amazon FSx for Windows File Server is a fully managed file server that supports Microsoft workloads and file systems, including the SMB protocol. It provides features such as user quotas, end-user file restore, and Microsoft Active Directory integration. Amazon EFS is a fully managed file system that supports the NFS protocol, not SMB. Amazon FSx for Lustre is a fully managed file system that supports high-performance computing workloads, not Microsoft workloads. Amazon EBS is a block storage service that does not provide a file system or SMB support. References: Amazon FSx for Windows File Server, Amazon FSx for Lustre, Amazon EFS, Amazon EBS

Amazon Elastic File System (Amazon EFS) is a fully managed, scalable, and serverless NFS (Network File System) file system specifically designed for use with AWS services and on-premises resources. It enables companies to create and configure file systems that can be accessed from multiple Amazon EC2instances simultaneously, making it ideal for use cases that require shared file storage for AWS compute services.

Why Amazon EFS Fits the Requirements:

Managed Service: Amazon EFS is a fully managed file storage service that simplifies the process of setting up and managing NFS file systems.

Scalability and Elasticity: EFS automatically scales to accommodate the storage needs of applications, without the need to provision or manage storage capacity.

NFS Compatibility: Amazon EFS natively supports the NFSv4 protocol, making it compatible with a wide range of applications and workloads that require NFS access.

Integration with AWS Compute Services: EFS integrates seamlessly with Amazon EC2 and other AWS services, providing a shared file storage solution across multiple instances and services within the AWS cloud environment.

Why Other Options Do Not Fit:

A. Amazon Elastic Block Store (Amazon EBS): While EBS provides block-level storage that can be attached to individual EC2 instances, it is not a file system, nor does it provide managed NFS file storage capabilities. EBS is designed for single-instance access rather than shared file access across multiple instances.

B. AWS Storage Gateway Tape Gateway: Tape Gateway is designed for archival purposes and allows companies to store virtual tape backups in Amazon S3 or Glacier. It does not support NFS file storage and is not intended for regular compute access.

C. Amazon S3 Glacier Flexible Retrieval: Amazon S3 Glacier is optimized for data archiving and long-term storage of infrequently accessed data, but it does not provide NFS file system capabilities, nor is it suitable for high-performance access needs associated with compute services.

For more details, you can refer to theAWS Cloud Practitioner Essentialscontent, specifically the modules onStorage Serviceswhere Amazon EFS is covered as the managed NFS file storage solution offered by AWS.

AWS Direct Connect provides a dedicated private network connection from on-premises data centers directly to the AWS Cloud, bypassing the public internet. This setup is ideal for reducing network costs, increasing bandwidth throughput, and providing a more consistent network experience compared to standard internet connections. Other services, such as Amazon VPC, relate to networking but do not establish a private network connection from on-premises to AWS.

AWS Organizationsis a no-cost service that helps you centrally manage and govern your environment as you grow and scale your AWS resources. With AWS Organizations, you can create new AWS accounts, invite existing accounts to join your organization, and apply policies to groups of accounts for governance. While some features within AWS services incur additional costs, using AWS Organizations itself does not add any direct costs.

A. Amazon SageMaker: Incorrect, as it is a fully managed service for building, training, and deploying machine learning models, and it is not free.

B. AWS Config: Incorrect, as while it offers some free-tier usage, it generally incurs charges for recording and evaluating configuration changes.

D. Amazon CloudWatch: Incorrect, as certain CloudWatch metrics, custom metrics, and alarms have associated costs beyond the free tier.

AWS Outposts is an AWS offering that brings AWS infrastructure and services to a customer's on-premises location. It allows companies to run AWS services locally while meeting any regulatory or compliance requirements to keep data or applications on-premises. Dedicated Instances are EC2 instances that run on hardware dedicated to a single customer but are still within AWS data centers. Amazon CloudFront is a CDN service, and AWS Fargate is a serverless compute engine for containers, neither of which meets the requirement for running an application on-premises.

The AWS Cloud Adoption Framework (AWS CAF) security perspective helps users achieve the confidentiality, integrity, and availability of their data and cloud workloads. It comprises nine capabilities that are grouped into three categories: preventive, detective, and responsive. Incident response and infrastructure protection are two of the capabilities in the responsive and preventive categories, respectively. Incident response helps users prepare for and respond to security incidents in a timely and effective manner, using tools and processes that leverage AWS features and services. Infrastructure protection helps users implement security controls and mechanisms to protect their cloud resources, such as network, compute, storage, and database, from unauthorized access or malicious attacks. References: Security perspective: compliance and assurance, AWS Cloud Adoption Framework

AWS IAM Identity Center (AWS Single Sign-On) is a cloud-based service that makes it easy to centrally manage single sign-on (SSO) access to multiple AWS accounts and business applications. You can use AWS SSO to enable your users to sign in to the AWS Management Console or the AWS Command Line Interface (AWS CLI) with their existing corporate credentials2. You can also manage SSO access and user permissions across all your AWS accounts in AWS Organizations3. References: AWS Single Sign-On - AWS Documentation, AWS Organizations - AWS Documentation
