CLF-C02 Exam Preparation Material | AWS Certified Cloud Practitioner

Explanation:
The correct answer is B because Application Load Balancer is an AWS load balancer that will meet the requirements and take the least amount of effort to deploy. Application Load Balancer is a type of Elastic Load Balancing that operates at the application layer (layer 7) of the OSI model and routes requests to targets based on the content of the request. Application Load Balancer supports advanced features, such as path-based routing, host-based routing, and HTTP header-based routing. The other options are incorrect because they are not AWS load balancers that will meet the requirements and take the least amount of effort to deploy. Network Load Balancer is a type of Elastic Load Balancing that operates at the transport layer (layer 4) of the OSI model and routes requests to targets based on the destination IP address and port. Network Load Balancer does not support path-based routing. AWS OpsWorks Load Balancer is not an AWS load balancer, but rather a feature of AWS OpsWorks that enables users to attach an Elastic Load Balancing load balancer to a layer of their stack. Custom Load Balancer on Amazon EC2 is not an AWS load balancer, but rather a user-defined load balancer that runs on an Amazon EC2 instance. Custom Load Balancer on Amazon EC2 requires more effort to deploy and maintain than an AWS load balancer.

Explanation:
Amazon EC2 is the AWS service that requires the customer to be fully responsible for applying operating system patches. Amazon EC2 is a service that provides secure, resizable compute capacity in the cloud. Customers can launch virtual servers called instances and choose from various configurations of CPU, memory, storage, and networking resources1. Customers have full control and access to their instances, which means they are also responsible for managing and maintaining them, including applying operating system patches2. Customers can use AWS Systems Manager Patch Manager, a feature of AWS Systems Manager, to automate the process of patching their EC2 instances with both security-related updates and other types of updates3.
A company wants an AWS service to collect and process 10 TB of data locally and transfer the data to AWS. The company has intermittent connectivity.
Which AWS service will meet these requirements?
AWS Database Migration Service (AWS DMS)
AWS DataSync
AWS Backup
AWS Snowball Edge
Answer D
The correct answer is D. AWS Snowball Edge.
AWS Snowball Edge is a physical device that can be used to collect and process data locally and then transfer it to AWS. It is designed for situations where there is limited or intermittent network connectivity, or where bandwidth costs are high.AWS Snowball Edge can store up to 80 TB of data and has compute and storage capabilities to run applications on the device1.
AWS Database Migration Service (AWS DMS) is a service that helps migrate databases to AWS.It does not collect or process data locally, nor does it work offline2.
AWS DataSync is a service that helps transfer data between on-premises storage systems and AWS storage services.It does not collect or process data locally, and it requires a network connection to work3.
AWS Backup is a service that helps automate and manage backups across AWS services. It does not collect or process data locally, nor does it transfer data to AWS.It only backs up data that is already in AWS4.

AWS WAF Overview:
AWS Web Application Firewall (WAF) allows users to create rules to block or allow traffic based on IP addresses, request patterns, and other conditions.
It is ideal for blocking traffic from a specific IP address.
Why AWS WAF Meets the Requirement:
The company can create a WAF rule to block traffic from the malicious IP address.
WAF integrates with services like Amazon CloudFront, Application Load Balancer, and API Gateway.
Why Other Options Are Incorrect:
A. AWS Shield:Protects against DDoS attacks but does not allow custom IP blocking.
B. AWS Config:Monitors resource configurations but does not block IPs.
C. Amazon GuardDuty:Detects threats but does not block traffic directly.

Explanation:
AWS Glue is a serverless data integration service that makes it easy to discover, prepare, move, and integrate data from multiple sources for analytics, machine learning, and application development. You can use various data integration engines, such as ETL, ELT, batch, and streaming, and manage your data in a centralized data catalog. AWS Glue is designed specifically for extract, transform, and load (ETL) data, whereas the other options are not.

Explanation:
AWS App Runneris a fully managed service that makes it easy for developers to quickly deploy containerized web applications and APIs at scale. It can automatically build container images from source code or directly from a container registry, and then deploy the application without requiring
deep container knowledge or expertise.
AWS App Runner meets the requirements of:
Automatically creating container images from source code.
Managing the deployment of the containerized application with minimal operational overhead.
Why other options are not suitable:
A. AWS Elastic Beanstalk: While it simplifies deploying and scaling web applications, it does not automatically create container images from source code.
B. Amazon Elastic Container Service (Amazon ECS): ECS is a container orchestration service that requires more manual setup for creating and managing container images and deployments.
D. Amazon EC2: This service provides virtual servers but does not offer managed container image creation or deployment.
