Exam AWS Certified Cloud Practitioner topic 1 question 24 discussion

vote for C , While VPC peering can be used to establish a connection between two VPCs, it has some limitations that make it less suitable for this scenario. VPC peering is only available for VPCs that are located in the same AWS Region, so it cannot be used to establish a connection between VPCs in different Regions. Additionally, VPC peering does not support transitive peering relationships, so it cannot be used to connect more than two VPCs in a chain. In contrast, AWS Direct Connect can be used to establish a dedicated network connection between VPCs in different Regions, and it supports multiple VPCs in a chain. This makes it a better fit for the scenario described in the question.

they can establish connection using vpc peering

The correct answer is B. VPC peering. VPC Endpoints: These are used to connect VPCs to AWS services without requiring an internet gateway, but they do not support cross-region VPC connections directly.

VPC peering

VPC peering allows you to connect two VPCs in the same or different AWS Regions using the existing infrastructure of the VPCs.

B. VPC peering Explanation: VPC peering allows you to connect two VPCs within the same AWS account or different AWS accounts, even if they are in different AWS Regions. With VPC peering, the two VPCs can communicate with each other as if they are on the same network, leveraging the existing resources and configurations within each VPC. VPC peering does not require a separate VPN connection or additional hardware. It uses the AWS backbone network to route traffic between the peered VPCs. This option fits the scenario described as it enables the company to establish a connection between the two VPCs while utilizing their existing infrastructure.

VPC Peering enables non-transitive connection between VPC across account and regions.

VPC peering

Segundo a documentação: "As VPCs podem estar em regiões diferentes (também conhecidas como conexão de emparelhamento da VPC entre regiões)." https://docs.aws.amazon.com/pt_br/vpc/latest/peering/what-is-vpc-peering.html

C. AWS Direct Connect. AWS Direct Connect is a network service that provides dedicated network connections between your on-premises data centers and AWS infrastructure. It can also be used to establish connections between VPCs in different AWS Regions. With Direct Connect, you can create virtual interfaces that allow you to route traffic between VPCs in different Regions as if they were on the same network. AWS Client VPN (A) is used for secure remote access to your VPCs but is not designed for interconnecting VPCs in different Regions. VPC peering (B) allows you to establish private connectivity between VPCs in the same AWS Region, but it does not work across Regions. VPC endpoints (D) are used for securely connecting your VPC to AWS services (such as S3 or DynamoDB) without using the public internet. They are not used for interconnecting VPCs in different Regions.

C. AWS Direct Connect. AWS Direct Connect provides a dedicated network connection between your on-premises data center or network and AWS. It can also be used to establish connections between VPCs in different AWS Regions. With Direct Connect, you can create private virtual interfaces (VIFs) that connect your VPCs in different regions, allowing for secure and reliable communication without going over the public internet.

AWS direct connect is the answer for this Explanation:AWS Direct Connect: This service provides a dedicated connection between your data center and an AWS Direct Connect location. It can be used to connect your VPCs to your on-premises networks, as well as to connect VPCs in different Regions. why you should not go for VPC peering Explanation: This service allows you to create a direct connection between two VPCs in the same Region. It is a good choice for companies that want to connect VPCs that are in close proximity to each other.

B. VPC peering

VPC peering is incorrect because it connects VPCs within the same region. the AWS Direct Connect can be used for multiple VPCs within the same AWS region or across different regions (using AWS Direct Connect Gateway). Also, it connects vpc with on-premises data centers. correct: C Incorrect: B

VPC peering is a networking connection between two VPCs that routes traffic between them using private IPv4 or IPv6 addresses. This is the most cost-effective way to connect two VPCs in different Regions. AWS Direct Connect is a dedicated network connection between your on-premises network and AWS. It is a good choice for connecting two VPCs in different Regions, but it is more expensive than VPC peering.
