A global company operates all its non-production environments out of three AWS Regions: eu-west-1, us-east-1, and us-west-1. The company hosts all its production workloads in two on-premises data centers. The company has 60 AWS accounts and each account has two VPCs in each Region. Each VPC has a virtual private gateway where two VPN connections terminate for resilient connectivity to the data centers. The company has 360 VPN tunnels to each data center, resulting in high management overhead. The total VPN throughput for each Region is 500 Mbps.

The company wants to migrate the production environments to AWS. The company needs a solution that will simplify the network architecture and allow for future growth. The production environments will generate an additional 2 Gbps of traffic per Region back to the data centers. This traffic will increase over time.
Which solution will meet these requirements?

  1. Set up an AWS Direct Connect connection from each data center to AWS in each Region. Create and attach private VIFs to a single Direct Connect gateway. Attach the Direct Connect gateway to all the VPCs. Remove the existing VPN connections that are attached directly to the virtual private gateways.
  2. Create a single transit gateway with VPN connections from each data center. Share the transit gateway with each account by using AWS Resource Access Manager (AWS RAM). Attach the transit gateway to each VPC. Remove the existing VPN connections that are attached directly to the virtual private gateways.
  3. Create a transit gateway in each Region with multiple newly commissioned VPN connections from each data center. Share the transit gateways with each account by using AWS Resource Access Manager (AWS RAM). In each Region, attach the transit gateway to each VPRemove the existing VPN connections that are attached directly to the virtual private gateways.
  4. Peer all the VPCs in each Region to a new VPC in each Region that will function as a centralized transit VPC. Create new VPN connections from each data center to the transit VPCs. Terminate the original VPN connections that are attached to all the original VPCs. Retain the new VPN connection to the new transit VPC in each Region.

Answer(s): C



A company is building its website on AWS in a single VPC. The VPC has public subnets and private subnets in two Availability Zones. The website has static content such as images. The company is using Amazon S3 to store the content.

The company has deployed a fleet of Amazon EC2 instances as web servers in a private subnet. The EC2 instances are in an Auto Scaling group behind an Application Load Balancer. The EC2 instances will serve traffic, and they must pull content from an S3 bucket to render the webpages. The company is using AWS Direct Connect with a public VIF for on-premises connectivity to the S3 bucket.

A network engineer notices that traffic between the EC2 instances and Amazon S3 is routing through a NAT gateway. As traffic increases, the company's costs are increasing. The network engineer needs to change the connectivity to reduce the NAT gateway costs that result from the traffic between the EC2 instances and Amazon S3.

Which solution will meet these requirements?

  1. Create a Direct Connect private VIF. Migrate the traffic from the public VIF to the private VIF.
  2. Create an AWS Site-to-Site VPN tunnel over the existing public VIF.
  3. Implement interface VPC endpoints for Amazon S3. Update the VPC route table.
  4. Implement gateway VPC endpoints for Amazon S3. Update the VPC route table.

Answer(s): D



A company wants to improve visibility into its AWS environment. The AWS environment consists of multiple VPCs that are connected to a transit gateway. The transit gateway connects to an on-premises data center through an AWS Direct Connect gateway and a pair of redundant Direct Connect connections that use transit VIFs. The company must receive notification each time a new route is advertised to AWS from on premises over Direct Connect.
What should a network engineer do to meet these requirements?

  1. Enable Amazon CloudWatch metrics on Direct Connect to track the received routes. Configure a CloudWatch alarm to send notifications when routes change.
  2. Onboard Transit Gateway Network Manager to Amazon CloudWatch Logs Insights. Use Amazon EventBridge (Amazon CloudWatch Events) to send notifications when routes change.
  3. Configure an AWS Lambda function to periodically check the routes on the Direct Connect gateway and to send notifications when routes change.
  4. Enable Amazon CloudWatch Logs on the transit VIFs to track the received routes. Create a metric filter Set an alarm on the filter to send notifications when routes change.

Answer(s): B



A software company offers a software-as-a-service (SaaS) accounting application that is hosted in the AWS Cloud The application requires connectivity to the company's on-premises network. The company has two redundant 10 GB AWS Direct Connect connections between AWS and its on-premises network to accommodate the growing demand for the application.

The company already has encryption between its on-premises network and the colocation. The company needs to encrypt traffic between AWS and the edge routers in the colocation within the next few months. The company must maintain its current bandwidth.

What should a network engineer do to meet these requirements with the LEAST operational overhead?

  1. Deploy a new public VIF with encryption on the existing Direct Connect connections. Reroute traffic through the new public VIF.
  2. Create a virtual private gateway Deploy new AWS Site-to-Site VPN connections from on premises to the virtual private gateway Reroute traffic from the Direct Connect private VIF to the new VPNs.
  3. Deploy a new pair of 10 GB Direct Connect connections with MACsec. Configure MACsec on the edge routers. Reroute traffic to the new Direct Connect connections. Decommission the original Direct Connect connections
  4. Deploy a new pair of 10 GB Direct Connect connections with MACsec. Deploy a new public VIF on the new Direct Connect connections. Deploy two AWS Site-to-Site VPN connections on top of the new public VIF. Reroute traffic from the existing private VIF to the new Site-to-Site connections. Decommission the original Direct Connect connections.
