Question 1

A company needs to securely transfer sensitive information between their on-premises data center and AWS. They require a dedicated network connection. What solution is most appropriate for their needs?

Correct Answer: AWS Direct Connect

AWS Direct Connect provides a dedicated network connection from on-premises to AWS, ensuring a secure data transfer. The other options don't offer a dedicated connection.

Question 2

A company has a large number of offices across the globe. They want to connect their on-premises networks to AWS with each office having its own VPC. What's the best solution for this scenario?

Correct Answer: AWS Transit Gateway

AWS Transit Gateway simplifies the process of connecting multiple VPCs with on-premises networks by acting as a hub. The other solutions are not suitable for connecting multiple VPCs.

Question 3

You have two VPCs in the same AWS Region and account with non-overlapping CIDR blocks. EC2 instances in VPC-A must privately access resources in VPC-B using their private IP addresses. No transitive routing or centralized inspection is required. Which option provides the simplest, lowest-latency, AWS-managed connectivity between the two VPCs?

Correct Answer: VPC peering

VPC peering creates a direct, private network connection between two VPCs with non-overlapping CIDR blocks, enabling instances to communicate using private IPs over the AWS backbone with low latency and no need for internet gateways or customer-managed VPN endpoints. It is the simplest AWS-managed option for one-to-one VPC connectivity when no transitive routing is required. A NAT gateway is for outbound internet access, not VPC-to-VPC connectivity. A VPN connection would traverse the public internet, adds operational complexity and latency, and is unnecessary between VPCs when peering is available. Direct Connect is designed to connect on-premises networks to AWS, not to connect two VPCs together.
