ASecurity Groupacts as a virtual firewall for your Amazon EC2 instances to control inbound and outbound traffic. It provides granular control over network connections to and from a specific EC2 instance or set of instances. Unlike Network ACLs, which operate at the subnet level, Security Groups operate at the instance level, allowing control over network traffic for individual instances.

A. Network ACL: Incorrect, as it controls traffic at the subnet level and not for individual instances.

B. AWS WAF: Incorrect, as AWS WAF is a web application firewall that helps protect web applications from common web exploits but is not designed for controlling instance-level traffic.

C. Route table: Incorrect, as route tables are used for network routing within a VPC and do not act as firewalls.

AWS Service Catalog enables companies to create, manage, and distribute catalogs of approved infrastructure as code (IaC) templates and software configurations. This service supports infrastructure automation by allowing users to deploy resources using predefined templates, which align with the company's policies and best practices. It helps in managing cloud resources at scale by utilizing IaC principles, enabling consistent deployments, and enforcing governance across AWS resources. AWS Service Catalog is an excellent choice for organizations implementing IaC.

 The correct answer is B because AWS CloudTrail is an AWS service that a cloud engineer can use to view API calls to AWS services. AWS CloudTrail is a service that enables customers to track user activity and API usage across their AWS account. AWS CloudTrail records the details of every API call made to AWS services, such as the identity of the caller, the time of the call, the source IP address of the caller, the parameters and responses of the call, and more. Customers can use AWS CloudTrail to audit, monitor, and troubleshoot their AWS resources and actions. The other options are incorrect because they are not AWS services that a cloud engineer can use to view API calls to AWS services. Amazon CloudWatch is an AWS service that enables customers to collect, analyze, and visualize metrics, logs, and events from their AWS resources and applications. AWS Config is an AWS service that enables customers to assess, audit, and evaluate the configurations of their AWS resources. AWS Artifact is an AWS service that provides customers with on-demand access to AWS compliance reports and select online agreements. Reference: AWS CloudTrail FAQs

Under theAWS Shared Responsibility Model, AWS manages securityofthe cloud (such as physical infrastructure and virtualization), while customers are responsible for securityinthe cloud. This means that customers are responsible for:

B. Encrypt data and maintain data integrity: Correct, as customers are responsible for securing their data, including encryption and maintaining its integrity.

D. Maintain identity and access management controls: Correct, as customers are responsible for managing access to their AWS resources, including creating and managing IAM users, roles, and permissions.

A. Secure the virtualization layer: Incorrect, as AWS is responsible for securing the underlying virtualization layer.

C. Patch the Amazon RDS operating system: Incorrect, as AWS handles patching and maintenance of the managed service’s underlying infrastructure.

E. Secure Availability Zones: Incorrect, as AWS is responsible for securing the physical infrastructure, including Availability Zones.

The AWS Cloud Adoption Framework (AWS CAF) is a tool that helps organizations plan and execute their cloud transformation journey. The AWS CAF defines four phases of the cloud transformation journey: Envision, Align, Launch, and Scale. Each phase has a specific purpose and outcome1:

Envision: This phase helps you define your vision, goals, and expected outcomes for your cloud transformation. It also helps you identify and prioritize transformation opportunities across four domains: business, people, governance, and platform2.

Align: This phase helps you identify capability gaps across six perspectives: business, people, governance, platform, security, and operations. It also helps you create strategies for improving your cloud readiness, ensure stakeholder alignment, and facilitate relevant organizational change management activities3.

Launch: This phase helps you deliver pilot initiatives in production and demonstrate incremental business value. It also helps you learn from pilots and adjust your approach before scaling to full production4.

Scale: This phase helps you expand production pilots and business value to desired scale and ensure that the business benefits associated with your cloud investments are realized and sustained.

The options A and B are the correct AWS CAF cloud transformation journey recommendations, as they are part of the four phases defined by the AWS CAF. The options C, D, and E are not AWS CAFcloud transformation journey recommendations, as they are not part of the four phases defined by the AWS CAF

According to the AWS shared responsibility model, AWS is responsible for protecting the infrastructure that runs all ofthe services offered in the AWS Cloud, such as data centers, hardware, software, networking, and facilities1. This includes the configuration of infrastructure devices, such as routers, switches, firewalls, and load balancers2. Customers are responsible for managing their data, applications, operating systems, security groups, and other aspects of their AWS environment1. Therefore, options A, B, and D are customer responsibilities, not AWS responsibilities. References: 1: AWS Well-Architected Framework - Elasticity; 2: Reactive Systems on AWS - Elastic

VPC Flow Logs is a feature that enables you to capture information about the IP traffic going to and from network interfaces in your VPC. Flow log data can be published to Amazon CloudWatch Logs, Amazon S3, or Amazon Kinesis Data Firehose. You can use VPC Flow Logs to diagnose network issues, monitor traffic patterns, detect security anomalies, and comply with auditing requirements34. References: Logging IP traffic using VPC Flow Logs - Amazon Virtual Private Cloud, New – VPC Traffic Mirroring – Capture & Inspect Network Traffic | AWS News Blog
