The AWS Management Console provides a web-based graphical user interface (GUI) that allows users to manage AWS services. It is user-friendly and accessible, enabling users to control and configure resources without needing to interact with AWS through code or command-line interfaces. AWS CLI and SDKs are command-line and programming tools, respectively, and do not offer a graphical interface.

Amazon RDS (Relational Database Service) supports SQL Server and other relational databases while handling administrative tasks such as backups, patching, monitoring, and scaling. This allows the company to migrate its SQL Server database without managing the infrastructure manually. Amazon EC2for SQL Server would require more administrative overhead, as the company would be responsible for the maintenance. Amazon DynamoDB and Aurora do not support SQL Server directly.

The Amazon EC2 Reserved Instance Marketplace allows customers to sell unused Standard Reserved Instances to other AWS users. This enables companies to recoup some of the costs if they no longer need certain RIs. Standard RIs cannot be converted to Savings Plans, and AWS Support does not facilitate the resale of RIs directly.

 Operations is an option that is a perspective that includes foundational capabilities of the AWS Cloud Adoption Framework (AWS CAF). Operations is one of the six perspectives of the AWS CAF, along with business, people, governance, platform, and security. Operations focuses on the processes and procedures to support the ongoing management and maintenance of the cloud-based IT assets. It covers topics such as monitoring, backup and recovery, change management, incident management, and automation5. Sustainability is not a perspective of the AWS CAF, but a concept that refers to the ability of a system to operate in an environmentally friendly and socially responsible manner. Performance efficiency is not a perspective of the AWS CAF, but a pillar of the AWS Well-Architected Framework. It focuses on using the right resources and services for the workload, monitoring performance, and continuously improving the efficiency of the solution. Reliability is not a perspective of the AWS CAF, but a pillar of the AWS Well-Architected Framework. It focuses on the ability of a system to recover from infrastructure or service disruptions, dynamically acquire computing resources to meet demand, and mitigate disruptions such as misconfigurations or transient network issues.

 Designing loosely coupled components is a design principle that should be considered when architecting in the AWS Cloud. Loose coupling is a way of designing systems to reduce interdependencies and minimize the impact of changes. Loose coupling allows components to interact with each other through well-defined interfaces, rather than direct references. This reducesthe risk of failures and errors propagating across the system, and enables greater scalability, availability, and maintainability5.

 Availability Zones contain multiple data centers. This is a characteristic of the AWS global infrastructure, which consists of AWS Regions, Availability Zones, and edge locations. AWS Regions are geographically isolated areas that contain multiple Availability Zones. Availability Zones are physically separate locations within an AWS Region that are engineered to be isolated from failures and connected by low-latency, high-throughput, and highly redundant networking. Each Availability Zone contains one or more data centers that house the servers and storage devices that run AWS services. Edge locations are sites that are located closer to the end users and provide caching and content delivery services. AWS Global InfrastructureAWS Certified Cloud Practitioner - aws.amazon.com

Application Load Balancer (ALB) integrates with AWS WAF to deploy and manage WAF rules for incoming traffic. ALB can route HTTP and HTTPS traffic and apply WAF rules to protect applications from common web exploits. Network Load Balancer does not support AWS WAF, and Trusted Advisor does not deploy WAF rules.

The reliability pillar of the AWS Well-Architected Framework includes the principle of testing recovery procedures to ensure systems can effectively recover from failures. Regular testing of recovery processes helps verify that systems are resilient and can handle potential disruptions. The other options align with different pillars like cost optimization and operational excellence.

The AWS best practice for using the AWS account root user credentials is to use them only when they alone must be used to perform a required function. The AWS account root user credentials have full access to all the resources in the account, and therefore pose a security risk if compromised or misused. You should create individual IAM users with the minimum necessary permissions for everyday tasks, and use AWS Organizations to manage multiple accounts. You should also enable multi-factor authentication (MFA) and rotate the password for the root user regularly. Some of the functions that require the root user credentials are changing the account name, closing the account, changing the support plan, and restoring an IAM user’s access.

AWS Organizations Overview:

AWS Organizations allows a company to manage multiple AWS accounts under a single organization.

Through the feature of consolidated billing, a company can receive a single bill for all linked accounts.

Key Features of Consolidated Billing in AWS Organizations:

Aggregates usage across accounts to take advantage of volume pricing discounts.

Provides detailed cost reports for individual linked accounts.

Simplifies payment processing by centralizing billing.

Why Other Options Are Incorrect:

A. AWS Billing and Cost Management console:Used for managing budgets and payments but does not set up consolidated billing.

C. AWS Cost and Usage Report:Provides detailed cost and usage reports but does not set up consolidated billing.

D. AWS Systems Manager:Focuses on operational management, not billing.

Using multiple Availability Zones within the same AWS Region meets the requirements for having instances in different locations with independent power and networking. Availability Zones are distinct physical locations within a region, each with separate power sources and networking. Edge locations are used for content delivery, and Amazon Connect and AWS Artifact locations are not relevant to EC2 deployment and infrastructure.

Amazon Rekognition is a machine learning service that can analyze and recognize objects, people, text, scenes, and activities in images and videos. It is specifically designed for organizing, categorizing, and searching large volumes of images based on various attributes. Amazon Transcribe is for speech-to-text, Amazon Aurora is a relational database service, and Amazon QuickSight is a business intelligence tool for data visualization.

Management of the guest operating systems is a customer’s responsibility, according to the AWS shared responsibility model. The AWS shared responsibility model defines the different security and compliance responsibilities of AWS and the customer. AWS is responsible for the security of the cloud, which includes the physical infrastructure, hardware, software, and facilities that run the AWS Cloud. The customer is responsible for security in the cloud, which includes the configuration and management of the guest operating systems, applications, data, and network traffic protection

Amazon CloudWatch is a monitoring and observability service built for DevOps engineers, developers, site reliability engineers (SREs), and IT managers. CloudWatch provides you with data and actionable insights to monitor your applications, respond to system-wide performance changes, optimize resource utilization, and get a unified view of operational health. CloudWatch collects monitoring and operational data in the form of logs, metrics, and events, providing you with a unified view of AWS resources, applications, and services that run on AWS and on-premises servers

The correct answer is A because Amazon CloudFront is an AWS service that provides secure delivery of data, videos, applications, and APIs to users globally with low latency and high transfer speeds. Amazon CloudFront is a fast content delivery network (CDN) that integrates with other AWS services, such as Amazon S3, Amazon EC2, AWS Lambda, and AWS Shield. Amazon CloudFront delivers content through a worldwide network of edge locations that are located close to the end users. The other options are incorrect because they are not AWS services that provide secure delivery of data, videos, applications, and APIs to users globally with low latency and high transfer speeds. Elastic Load Balancing is an AWS service that distributes incoming traffic across multiple targets, such as Amazon EC2 instances, containers, and IP addresses. Amazon S3 is an AWS service that provides object storage for data of any size and type. Amazon Elastic Transcoder is an AWS service that converts media files from their original source format into different formats that will play on various devices. Reference: Amazon CloudFront FAQs

AWS Organizations enables consolidated billing across multiple AWS accounts and allows for centralized management of security and compliance policies. It provides account grouping and centralized payment management, making it the optimal choice for a company requiring consolidated billing and centralized governance. AWS Cost and Usage Report only provides billing information, and AWS Config and Security Hub offer monitoring and security insights but do not handle billing consolidation.
