Difficulty: MediumHigh-Performing and Scalable Network Architectures

A financial services firm needs to establish a dedicated, private network connection between its on-premises datacenter and multiple VPCs located in the us−east−1us-east-1 and us−west−2us-west-2 Regions. The connection must provide consistent network performance, low latency, and support a minimum data transfer rate of 10 Gbps10\text{ Gbps} for real-time database replication. The solution must also scale to accommodate new VPCs in both Regions in the future.

Which combination of actions should a solutions architect take to meet these requirements? (Select TWO.)

  1. Establish a 10 Gbps10\text{ Gbps} AWS Direct Connect connection and create a transit virtual interface (transit VIF) associated with a Direct Connect gateway.Answer
  2. Associate the Direct Connect gateway with an AWS Transit Gateway in each Region to route traffic to the local VPCs.Answer
  3. C
    Deploy a single AWS Site-to-Site VPN connection and configure static routing to achieve the 10 Gbps10\text{ Gbps} throughput over the internet.
  4. D
    Configure stateful Network Access Control Lists (NACLs) at the subnet level to dynamically allow the returning database replication traffic.
  5. E
    Configure Amazon Route 53 with a latency routing policy to route the database replication traffic to the closest Region without setting up health checks.

Answer

Establishing a 10 Gbps10\text{ Gbps} AWS Direct Connect connection with a transit virtual interface (transit VIF) associated with a Direct Connect gateway, and associating the Direct Connect gateway with an AWS Transit Gateway in each Region.
Establishing a 10 Gbps10\text{ Gbps} AWS Direct Connect connection with a transit virtual interface (transit VIF) associated with a Direct Connect gateway provides the required dedicated private connection, high throughput, and consistent low latency. Associating the Direct Connect gateway with an AWS Transit Gateway in each Region enables highly scalable routing to multiple VPCs across different Regions, meeting the requirement to easily accommodate future VPCs.

Step-by-Step Solution

1
Provision a dedicated connection using AWS Direct Connect.
A 10 Gbps10\text{ Gbps} private, dedicated physical connection is established between the on-premises datacenter and an AWS Direct Connect location.
Provides the required 10 Gbps10\text{ Gbps} throughput and consistent low-latency network performance.
2
Create a transit virtual interface (transit VIF) and associate it with a Direct Connect gateway.
The Direct Connect connection is logicalized to route traffic to the Direct Connect gateway using a Transit VIF.
A Transit VIF is required to connect AWS Direct Connect to AWS Transit Gateway.
3
Associate the Direct Connect gateway with AWS Transit Gateways in both the local and remote Regions.
The Direct Connect gateway routes traffic from the on-premises network to Transit Gateways across multiple AWS Regions.
Transit Gateway allows central management and scaling of connections to multiple VPCs in each Region, accommodating future VPC additions easily.

Key Concept

AWS Direct Connect combined with Direct Connect Gateway and AWS Transit Gateway provides high-performance, private, and highly scalable hybrid network architectures across multiple AWS Regions.
