Amazon AWS Certified Cloud Practitioner CLF-C02 Exam Questions

Answer : B

AWS Storage Gateway is a hybrid cloud storage service that allows you to extend your on-premises file storage capabilities to the AWS Cloud. AWS Storage Gateway file gateway enables you to store and access your files in Amazon S3 using industry-standard file protocols such as NFS and SMB. File gateway caches frequently accessed files locally, providing low-latency access to your data. File gateway also optimizes the transfer of data between your on-premises environment and AWS, minimizing the amount of bandwidth consumed. By using file gateway, you can retain the performance benefit of sharing content locally while leveraging the scalability, durability, and cost-effectiveness of Amazon S3.Reference:AWS Storage Gateway,File Gateway

Answer : D

Amazon EC2 Auto Scaling is a service that helps you maintain application availability and allows you to automatically add or remove EC2 instances according to definable conditions. You can create collections of EC2 instances, called Auto Scaling groups, and specify the minimum and maximum number of instances in each group. You can also define scaling policies that adjust the number of instances based on the demand on your application.Amazon EC2 Auto Scaling helps you improve the performance, reliability, and cost-efficiency of your EC2workloads123.Reference:1:VDI Desktops - Amazon WorkSpaces Family - AWS,2:What is Amazon EC2 Auto Scaling? - Amazon EC2 Auto Scaling,3:Discover Amazon EC2 Auto Scaling Unit | Salesforce Trailhead

Answer : A, D

The correct answers are A and D because network infrastructure and virtualization of infrastructure and physical security of hardware are AWS responsibilities according to the AWS shared responsibility model. The AWS shared responsibility model is a framework that defines the division of responsibilities between AWS and the customer for security and compliance. AWS is responsible for the security of the cloud, which includes the global infrastructure, such as the regions, availability zones, and edge locations; the hardware, software, networking, and facilities that run the AWS services; and the virtualization layer that separates the customer instances and storage. The customer is responsible for the security in the cloud, which includes the customer data, the guest operating systems, the applications, the identity and access management, the firewall configuration, and the encryption. The other options are incorrect because they are not AWS responsibilities according to the AWS shared responsibility model. Security of application data, guest operatingsystems, and credentials and policies are customer responsibilities according to the AWS shared responsibility model.

Answer : A

Answer : A

On-Demand Instances are the most cost-efficient pricing model for an uninterruptible workload that runs once a year for 24 hours. On-Demand Instances let you pay for compute capacity by the hour or second, depending on which instances you run. No long-term commitments or up-front payments are required.You can increase or decrease your compute capacity to meet the demands of your application and only pay the specified hourly rates for the instance you use1.This model is suitable for developing/testing applications with short-term or unpredictable workloads2. The other pricing models are not cost-efficient for this use case. Reserved Instances and Savings Plans require a commitment to a consistent amount of usage, in USD per hour, for a term of 1 or 3 years.They provide significant discounts compared to On-Demand Instances, but they are not flexible or scalable for workloads that run only once a year12. Spot Instances are the cheapest option, but they are not suitable for uninterruptible workloads, as they can be reclaimed by AWS at any time.They are recommended for applications that have flexible start and end times, or that are only feasible at very low compute prices12. Dedicated Instances are designed for compliance and licensing requirements, not for cost optimization.They are more expensive than the other options, as they run on single-tenant hardware12.Reference:Amazon EC2 -- Secure and resizable compute capacity -- AWS,Amazon EC2 - How AWS Pricing Works

Answer : C

Amazon EC2 Spot Instancesoffer spare AWS compute capacity at a significantly reduced cost compared to On-Demand Instances. Spot Instances are ideal for fault-tolerant and flexibleworkloads that can tolerate interruptions, such as batch jobs, data processing, or large-scale computations. These instances may be interrupted by AWS if there is a demand for capacity, but they provide the best cost optimization for workloads that can handle such interruptions.

Why other options are not suitable:

A . Amazon Macie: A data security and privacy service, not relevant to running batch jobs.

B . Amazon Neptune: A graph database service, not relevant to compute optimization.

D . Amazon EC2 On-Demand Instances: Provide flexible compute capacity but at a higher cost than Spot Instances, which are more suitable for cost optimization.

Answer : B

AWS Artifact is the AWS service that can provide security and compliance documents for an upcoming audit. AWS Artifact is a self-service portal that allows users to access and download AWS compliance reports and agreements.These documents provide evidence of AWS's compliance with global, regional, and industry-specific security standards and regulations
