Dedicated Connections

5 minutes 5 Questions

Dedicated connections are a type of AWS Direct Connect connection that provides a dedicated network circuit between your on-premises data center and AWS. This dedicated circuit ensures consistent network performance, improved security, and increased bandwidth. With a dedicated connection, you can establish a dedicated private connection between your organization and AWS, bypassing the public internet, improving privacy, and minimizing latency. As a result, you can reduce costs and increase performance for critical applications running in AWS. Dedicated connections are often requested by larger organizations with higher bandwidth requirements, strict compliance needs, or more complex networking scenarios.

Guide: AWS Direct Connect - Dedicated Connections

AWS Direct Connect provides a dedicated network connection from your premises to AWS. This is important to ensure the predictable performance of your data transfer as well as increase bandwidth throughput.
Dedicated Connections: This is a physical Ethernet connection associated with a single customer. They are provisioned on single-tenant physical hardware.
How it works: With AWS Direct Connect, you perform a cross-connect between your network and an AWS Direct Connect router. Once the Dedicated Connection is set up, you create a virtual interface linking the AWS Direct Connect connection to a given AWS service.
Exam Tips:
- Understand the difference between a dedicated and hosted connection.
- Know how to set up and establish a dedicated connection.
Typical exam questions might ask you to troubleshoot issues with a Direct Connect connection or determine the appropriate use case for a Dedicated Connection versus a hosted connection.

Question 1

A company needs to transfer data securely between their on-premises data center and Amazon S3. The data transfer needs to be completed within 48 hours to meet the company's compliance requirements. What is the most cost-effective solution?

Amazon Connect AWS Snowball AWS Storage Gateway AWS Direct Connect

Correct Answer: AWS Direct Connect

AWS Direct Connect provides a dedicated, secure, low latency network connection between the on-premises data center and AWS. This is the most cost-effective solution in this scenario as the data transfer must be completed within 48 hours, and AWS Direct Connect's low latency ensures faster transfer rates. Other options may be slower or more expensive in this case.

Question 2

A gaming company is looking to host their game servers in AWS using dedicated instances for multiple Amazon VPCs. They intend to use AWS Direct Connect to ensure low latency between the players and the game servers. What is the appropriate configuration?

1 Direct Connect connection with public virtual interfaces Multiple Direct Connect connections with public virtual interfaces 1 Direct Connect connection with private virtual interfaces Multiple Direct Connect connections with private virtual interfaces

Correct Answer: 1 Direct Connect connection with private virtual interfaces

For hosting game servers in AWS with dedicated instances for multiple VPCs, using 1 Direct Connect connection with private virtual interfaces is the ideal solution. This allows each VPC to have its own dedicated, low latency connections to the on-premises network, ensuring efficient communication between the players and game servers. The other options involve public virtual interfaces that don't meet the requirement or transit virtual interfaces meant for AWS Transit Gateway.

Question 3

An e-commerce company recently migrated their critical applications to AWS. The application requires a maximum of 10 Gbps bandwidth to their on-premises data center. How can the company ensure consistent high bandwidth for this requirement?

5 Gbps AWS Direct Connect 10 Gbps AWS Direct Connect 3000Mbps AWS VPN 3000Mbps AWS Direct Connect with AWS VPN

Correct Answer: 3000Mbps AWS Direct Connect with AWS VPN

To meet the maximum 10 Gbps bandwidth requirement for the company's application, we can use AWS Direct Connect, which is a dedicated connection to AWS without using the public internet. We can use a 3000Mbps Direct Connect connection paired with AWS VPN to ensure consistent high bandwidth availability of 10 Gbps. The other options listed don't meet the specified bandwidth requirements.
