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

By implementingAWS CloudTrail, a company is adhering to the AWS Cloud design principle ofactivating traceability. AWS CloudTrail provides detailed logs of all API calls made in an AWS account, which helps monitor, troubleshoot, and detect unusual activity, thereby improving security and compliance. This supports the principle of "activating traceability" by enabling continuous monitoring and auditing of all actions and changes within the AWS environment.

B. Use serverless compute architectures: Incorrect, as this principle encourages the use of managed services that handle infrastructure, such as AWS Lambda, and is not directly related to CloudTrail.

C. Perform operations as code: Incorrect, as this principle emphasizes the use of code and automation for infrastructure management.

D. Go global in minutes: Incorrect, as this principle relates to the global deployment of applications and services.

Amazon EC2 On-Demand Instances are ideal for unpredictable workloads that do not require a long-term commitment. This option allows users to pay for compute capacity by the hour or second, with no long-term commitments. It is suitable for short-term, spiky, or unpredictable workloads that cannot be interrupted and require flexibility. Option A is better suited for Reserved Instances, Option B is ideal for Spot Instances, and Option D is more suited for Reserved Instances due to cost optimization for long-term use.

"There is no long-term commitment required when you purchase On-Demand Instances. You pay only for the seconds that your On-Demand Instances are in the running state, with a 60-second minimum. The price per second for a running On-Demand Instance is fixed, and is listed on the Amazon EC2 Pricing, On-Demand Pricing page. We recommend that you use On-Demand Instances for applications with short-term, irregular workloads that cannot be interrupted."https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-on-demand-instances.html

AWS Transit Gatewayis a network transit hub that customers can use to connect their Amazon VPCs and on-premises networks to a central hub. This service simplifies network management and reduces operational overhead by enabling a single gateway for managing multiple network connections. It facilitates seamless integration and routing between VPCs and on-premises networks.

A. Virtual private gateway: Incorrect, as it is used to connect a single VPC to an on-premises network through a VPN connection.

C. Internet gateway: Incorrect, as it provides internet access for instances in a VPC but does not connect multiple networks.

D. Customer gateway: Incorrect, as it represents the on-premises device or software application that connects to AWS, but it does not provide a central hub.

An access key is a pair of long-term credentials that consists of an access key ID and a secret access key. An access key is used to sign programmatic requests to the AWS CLI or AWS API (directly or using the AWS SDK). An access key allows a user to access the AWS account through a CLI, which is a tool that enables users to interact with AWS services using commands in a terminal or a script12.

The other options are not correct, because:

To access the AWS account as the AWS account root user, a user needs the email address and password associated with the account. The root user has complete access to all AWS resources and services in the account. However, it is not recommended to use the root user for everyday tasks3.

To access the AWS account through the AWS Management Console, a user needs a user name and password. The console is a web-based interface that allows users to manage their AWS resources and services using a graphical user interface4.

To access all of a company’s AWS accounts, a user needs to use AWS Organizations, which is a service that enables users to centrally manage and govern multiple AWS accounts. AWS Organizations allows users to create groups of accounts and apply policies to them5.

VPC peering and AWS Transit Gateway are two AWS services or features that give users the ability to create a network connection between two VPCs. VPC peering is a networking connection between two VPCs that enables you to route traffic between them privately. You can create a VPC peering connection between your own VPCs, with a VPC in another AWS account, or with a VPC in a different AWS Region. Traffic between peered VPCs never traverses the public internet. VPC peering does not support transitive peering relationships, which means that if VPC A is peered with VPC B, and VPC B is peered with VPC C, then VPC A and VPC C are not automatically peered789. AWS Transit Gateway is a networking service that acts as a regional router for your VPCs and on-premises networks. You can attach up to 5,000 VPCs and VPN connections to a single transit gateway and route traffic between them. AWS Transit Gateway simplifies the management and scalability of your network architecture, as you only need to create and manage a single connection from the central transit gateway to each connected network. AWS Transit Gateway supports transitive routing, which means that any network thatis attached to the transit gateway can communicate with any other network that is attached to the same transit gateway . References: 7: VPC peering - Amazon Virtual Private Cloud, 8: Connect VPCs using VPC peering - Amazon Virtual Private Cloud, 9: Amazon VPC-to-Amazon VPC connectivity options - Amazon Virtual Private Cloud, : [AWS Transit Gateway - Amazon Web Services], : [Connect VPCs using AWS Transit Gateway - Amazon Virtual Private Cloud], : [AWS Transit Gateway: Simplify Your Network Architecture]

According to the AWS shared responsibility model, AWS is responsible for the security of the cloud, while customers are responsible for the security in the cloud. This means that AWS is responsible for the physical servers, networking, and operating system that run Lambdafunctions, while customers are responsible for the security of their code and AWS IAM to the Lambda service and within their function1. Customers need to manage the code within the Lambda function, such as writing, testing, debugging, deploying, and updating the code, as well as ensuring that the code does not contain any vulnerabilities or malicious code that could compromise the security or performance of the function23. References: 2: AWS Lambda - Amazon Web Services (AWS), 3: AWS Lambda Documentation, 1: Amazon CLF-C02: What is customer responsibility under AWS … - PUPUWEB

An IAM credential report is a feature of AWS Identity and Access Management (IAM) that allows you to view and download a report that lists all IAM users in your account and the status of their various credentials, such as passwords, access keys, and MFA devices. You can use this reportto audit the security status of your IAM users and ensure that they follow the best practices for credential management1. References: 1: AWS Documentation - IAM User Guide - Getting credential reports for your AWS account
