A software-as-a-service (SaaS) company is migrating its private SaaS application to AWS. The company has hundreds of customers that connect to multiple data centers by using VPN tunnels. As the number of customers has grown, the company has experienced more difficulty in its effort to manage routing and segmentation of customers with complex NAT rules.

After the migration to AWS is complete, the company's AWS customers must be able to access the SaaS application directly from their VPCs. Meanwhile, the company's on-premises customers still must be able to connect through IPsec encrypted tunnels.

Which solution will meet these requirements?

  1. Connect the AWS customer VPCs to a shared transit gateway. Use AWS Site-to-Site VPN connections to the transit gateway for the on-premises customers
  2. Use AWS PrivateLink to connect the AWS customers. Use a third-party routing appliance in the SaaS application VPC to terminate onpremises Site-to-Site VPN connections.
  3. Peer each AWS customer's VPCs to the VPC that hosts the SaaS application. Create AWS Site-to-Site VPN connections on the SaaS VPC virtual private gateway.
  4. Use Site-to-Site VPN tunnels to connect each AWS customer's VPCs to the VPC that hosts the SaaS application. Use AWS Site-to-Site VPN to connect the on-premises customers.

Answer(s): B



A company's existing AWS environment contains public application servers that run on Amazon EC2 instances. The application servers run in a VPC subnet. Each server is associated with an Elastic IP address.

The company has a new requirement for firewall inspection of all traffic from the internet before the traffic reaches any EC2 instances. A security engineer has deployed and configured a Gateway Load Balancer (GLB) in a standalone VPC with a fleet of third-party firewalls.

How should a network engineer update the environment to ensure that the traffic travels across the fleet of firewalls?

  1. Deploy a transit gateway. Attach a GLB endpoint to the transit gateway. Attach the application VPC to the transit gateway. Update the application subnet route table's default route destination to be the GLB endpoint. Ensure that the EC2 instances' security group allows traffic from the GLB endpoint.
  2. Update the application subnet route table to have a default route to the GL On the standalone VPC that contains the firewall fleet, add a route in the route table for the application VPC's CIDR block with the GLB endpoint as the destination. Update the EC2 instances' security group to allow traffic from the GL
  3. Provision a GLB endpoint in the application VPC in a new subnet. Create a gateway route table with a route that specifies the application subnet CIDR block as the destination and the GLB endpoint as the target.
    Associate the gateway route table with the internet gateway in the application VP Update the application subnet route table's default route destination to be the GLB endpoint.
  4. Instruct the security engineer to move the GLB into the application VPC. Create a gateway route table.
    Associate the gateway route table with the application subnet. Add a default route to the gateway route table with the GLB as its destination. Update the route table on the GLB to direct traffic from the internet gateway to the application servers. Ensure that the EC2 instances' security group allows traffic from the GLB.

Answer(s): C



A company has an AWS Site-to-Site VPN connection between its office and its VPC. Users report occasional failure of the connection to the application that is hosted inside the VPC. A network engineer discovers in the customer gateway logs that the Internet Key Exchange (IKE) session ends when the connection to the application fails.

What should the network engineer do to bring up the IKE session if the IKE session goes down?

  1. Set the dead peer detection (DPD) timeout action to Clear. Initiate traffic from the VPC to on premises.
  2. Set the dead peer detection (DPD) timeout action to Restart. Initiate traffic from on premises to the VPC.
  3. Set the dead peer detection (DPD) timeout action to None. Initiate traffic from the VPC to on premises.
  4. Set the dead peer detection (DPD) timeout action to Cancel. Initiate traffic from on premises to the VPC.

Answer(s): B



A network engineer is designing a hybrid networking environment that will connect a company's corporate network to the company's AWS environment. The AWS environment consists of 30 VPCs in 3 AWS Regions.

The network engineer needs to implement a solution to centrally filter traffic by using a firewall that the company's security team has approved. The solution must give all the VPCs the ability to connect to each other. Connectivity between AWS and the corporate network must meet a minimum bandwidth requirement of 2 Gbps.

Which solution will meet these requirements?

  1. Deploy an IPsec VPN connection between the corporate network and a new transit gateway. Connect all VPCs to the transit gateway. Associate the approved firewall with the transit gateway.
  2. Deploy a single 10 Gbps AWS Direct Connect connection between the corporate network and virtual private gateway of each VPC. Connect the virtual private gateways to a Direct Connect gateway. Build an IPsec tunnel to a new transit VPC. Deploy the approved firewall to the transit VPC.
  3. Deploy two 1 Gbps AWS Direct Connect connections in different Direct Connect locations to connect to the corporate network. Build a transit VIF on each connection to a Direct Connect gateway. Associate the Direct Connect gateway with a new transit gateway for each Region. Configure the VIFs to use equal-cost multipath (ECMP) routing. Connect all the VPCs in the three Regions to the transit gateway. Configure the transit gateway route table to route traffic to an inspection VP Deploy the approved firewall to the inspection VP
  4. Deploy four 1 Gbps AWS Direct Connect connections in different Direct Connect locations to connect to the corporate network. Build a transit VIF on each connection to a Direct Connect gateway. Associate the Direct Connect gateway with a new transit gateway for each Region. Connect the transit gateways by using a transit gateway peering attachment. Configure the VIFs to use equal-cost multipath (ECMP) routing.
    Configure transit gateway route tables to route traffic to an inspection VPC. Deploy the approved firewall to the inspection VPC.

A company uses an AWS Direct Connect private VIF with a link aggregation group (LAG) that consists of two 10 Gbps connections. The company's security team has implemented a new requirement for external network connections to provide layer 2 encryption. The company's network team plans to use MACsec support for Direct Connect to meet the new requirement.

Which combination of steps should the network team take to implement this functionality? (Choose three.)

  1. Create a new Direct Connect LAG with new circuits and ports that support MACsec.
  2. Associate the MACsec Connectivity Association Key (CAK) and the Connection Key Name (CKN) with the new LAG.
  3. Associate the Internet Key Exchange (IKE) with the existing LAG.
  4. Configure the MACsec encryption mode on the existing LAG.
  5. Configure the MACsec encryption mode on the new LAG.
  6. Configure the MACsec encryption mode on each Direct Connect connection that makes up the existing

A company recently implemented a security policy that prohibits developers from launching VPC network infrastructure. The policy states that any time a NAT gateway is launched in a VPC, the company's network security team must immediately receive an alert to terminate the NAT gateway. The network security team needs to implement a solution that can be deployed across AWS accounts with the least possible administrative overhead. The solution also must provide the network security team with a simple way to view compliance history.

Which solution will meet these requirements?

  1. Develop a script that programmatically checks for NAT gateways in an AWS account, sends an email alert, and terminates the NAT gateway if a NAT gateway is detected. Deploy the script on an Amazon EC2 instance in each account. Use a cron job to run the script every 5 minutes. Log the results of the checks to an Amazon RDS for MySQL database.
  2. Create an AWS Lambda function that programmatically checks for NAT gateways in an AWS account, sends an email alert, and terminates the NAT gateway if a NAT gateway is detected. Deploy the Lambda function to each account by using AWS Serverless Application Model (AWS SAM) templates. Store the results of the checks on an Amazon OpenSearch Service cluster in each account.
  3. Enable Amazon GuardDuty. Create an Amazon EventBridge rule for the Behavior:EC2/ NATGatewayCreation GuardDuty finding type. Configure the rule to invoke an AWS Step Functions state machine to send an email alert and terminate a NAT gateway if a NAT gateway is detected. Store the runtime log as a text file in an Amazon S3 bucket.
  4. Create a custom AWS Config rule that checks for NAT gateways in an AWS account. Configure the AWS Config rule to perform an AWS Systems Manager Automation remediation action to send an email alert and terminate the NAT gateway if a NAT gateway is detected. Deploy the AWS Config rule and the Systems Manager runbooks to each account by using AWS CloudFormation StackSets

A company is running an online game on AWS. The game is played globally and is gaining popularity. Users are reporting problems with the game's responsiveness. Replay rates are dropping, and the company is losing subscribers. Game servers are located in the us-west-2 Region and use an Elastic Load Balancer to distribute client traffic.

The company has decided to deploy game servers to 11 additional AWS Regions to reduce the round-trip times of network traffic to game clients. A network engineer must design a DNS solution that uses Amazon Route 53 to ensure that user traffic is delivered to game servers with an optimal response time.

What should the network engineer do to meet these requirements?

  1. Create Route 53 records for the Elastic Load Balancers in each Region. Specify a weighted routing policy.
    Calculate the weight by using the number of clients in each Region.
  2. Create Route 53 records for the Elastic Load Balancers in each Region. Specify a latency routing policy. Set the Region to the Region where the Elastic Load Balancer is deployed.
  3. Create Route 53 records for the Elastic Load Balancers in each Region. Specify a multivalue answer routing policy. Test latency from the game client, and connect to the server with the best response.
  4. Create Route 53 records for the Elastic Load Balancers in each Region. Specify a geolocation routing policy. Set the location to the Region where the Elastic Load Balancer is deployed.

Answer(s): B



A network engineer needs to build an encrypted connection between an on-premises data center and a VPC. The network engineer attaches the VPC to a virtual private gateway and sets up an AWS Site-to-Site VPN connection. The VPN tunnel is UP after configuration and is working. However, during rekey for phase 2 of the VPN negotiation, the customer gateway device is receiving different parameters than the parameters that the device is configured to support.

The network engineer checks the IPsec configuration of the VPN tunnel. The network engineer notices that the customer gateway device is configured with the most secure encryption algorithms that the AWS Site-to-Site VPN configuration file provides.

What should the network engineer do to troubleshoot and correct the issue?

  1. Check the native virtual private gateway logs. Restrict the VPN tunnel options to the specific VPN parameters that the virtual private gateway requires.
  2. Check the native customer gateway logs. Restrict the VPN tunnel options to the specific VPN parameters that the customer gateway requires.
  3. Check Amazon CloudWatch logs of the virtual private gateway. Restrict the VPN tunnel options to the specific VPN parameters that the virtual private gateway requires.
  4. Check Amazon CloudWatch logs of the customer gateway. Restrict the VPN tunnel options to the specific VPN parameters that the customer gateway requires.
