A company deploys a new web application on Amazon EC2 instances. The application runs in private subnets in three Availability Zones behind an Application Load Balancer (ALB). Security auditors require encryption of all connections. The company uses Amazon Route 53 for DNS and uses AWS Certificate Manager (ACM) to automate SSL/TLS certificate provisioning. SSL/TLS connections are terminated on the ALB.

The company tests the application with a single EC2 instance and does not observe any problems. However, after production deployment, users report that they can log in but that they cannot use the application. Every new web request restarts the login process.

What should a network engineer do to resolve this issue?

  1. Modify the ALB listener configuration. Edit the rule that forwards traffic to the target group. Change the rule to enable group-level stickiness. Set the duration to the maximum application session length.
  2. Replace the ALB with a Network Load Balancer. Create a TLS listener. Create a new target group with the protocol type set to TLS Register the EC2 instances. Modify the target group configuration by enabling the stickiness attribute.
  3. Modify the ALB target group configuration by enabling the stickiness attribute. Use an application-based cookie. Set the duration to the maximum application session length.
  4. Remove the ALB. Create an Amazon Route 53 rule with a failover routing policy for the application name.
    Configure ACM to issue certificates for each EC2 instance.

Answer(s): C



A company recently migrated its Amazon EC2 instances to VPC private subnets to satisfy a security compliance requirement. The EC2 instances now use a NAT gateway for internet access. After the migration, some long-running database queries from private EC2 instances to a publicly accessible third-party database no longer receive responses. The database query logs reveal that the queries successfully completed after 7 minutes but that the client EC2 instances never received the response.

Which configuration change should a network engineer implement to resolve this issue?

  1. Configure the NAT gateway timeout to allow connections for up to 600 seconds.
  2. Enable enhanced networking on the client EC2 instances.
  3. Enable TCP keepalive on the client EC2 instances with a value of less than 300 seconds.
  4. Close idle TCP connections through the NAT gateway.

Answer(s): C



A company uses AWS Direct Connect to connect its corporate network to multiple VPCs in the same AWS account and the same AWS Region. Each VPC uses its own private VIF and its own virtual LAN on the Direct Connect connection. The company has grown and will soon surpass the limit of VPCs and private VIFs for each connection.

What is the MOST scalable way to add VPCs with on-premises connectivity?

  1. Provision a new Direct Connect connection to handle the additional VPCs. Use the new connection to connect additional VPCs.
  2. Create virtual private gateways for each VPC that is over the service quota. Use AWS Site-to-Site VPN to connect the virtual private gateways to the corporate network.
  3. Create a Direct Connect gateway, and add virtual private gateway associations to the VPCs. Configure a private VIF to connect to the corporate network.
  4. Create a transit gateway, and attach the VPCs. Create a Direct Connect gateway, and associate it with the transit gateway. Create a transit VIF to the Direct Connect gateway.

Answer(s): D



A network engineer is designing a hybrid architecture that uses a 1 Gbps AWS Direct Connect connection between the company's data center and two AWS Regions: us-east-1 and eu-west-1. The VPCs in us-east-1 are connected by a transit gateway and need to access several on-premises databases. According to company policy, only one VPC in eu-west-1 can be connected to one on-premises server. The on-premises network segments the traffic between the databases and the server.

How should the network engineer set up the Direct Connect connection to meet these requirements?

  1. Create one hosted connection. Use a transit VIF to connect to the transit gateway in us-east-1. Use a private VIF to connect to the VPC in eu-west-1. Use one Direct. Connect gateway for both VIFs to route from the Direct Connect locations to the corresponding AWS Region along the path that has the lowest latency.
  2. Create one hosted connection. Use a transit VIF to connect to the transit gateway in us-east-1. Use a private VIF to connect to the VPC in eu-west-1. Use two Direct Connect gateways, one for each VIF, to route from the Direct Connect locations to the corresponding AWS Region along the path that has the lowest latency.
  3. Create one dedicated connection. Use a transit VIF to connect to the transit gateway in us-east-1. Use a private VIF to connect to the VPC in eu-west-1. Use one Direct Connect gateway for both VIFs to route from the Direct Connect locations to the corresponding AWS Region along the path that has the lowest latency.
  4. Create one dedicated connection. Use a transit VIF to connect to the transit gateway in us-east-1. Use a private VIF to connect to the VPC in eu-west-1. Use two Direct Connect gateways, one for each VIF, to route from the Direct Connect locations to the corresponding AWS Region along the path that has the lowest latency.

Answer(s): D



A company has deployed an application in a VPC that uses a NAT gateway for outbound traffic to the internet. A network engineer notices a large quantity of suspicious network traffic that is traveling from the VPC over the internet to IP addresses that are included on a deny list. The network engineer must implement a solution to determine which AWS resources are generating the suspicious traffic. The solution must minimize cost and administrative overhead.

Which solution will meet these requirements?

  1. Launch an Amazon EC2 instance in the VPC. Use Traffic Mirroring by specifying the NAT gateway as the source and the EC2 instance as the destination. Analyze the captured traffic by using open-source tools to identify the AWS resources that are generating the suspicious traffic.
  2. Use VPC flow logs. Launch a security information and event management (SIEM) solution in the VPC.
    Configure the SIEM solution to ingest the VPC flow logs. Run queries on the SIEM solution to identify the AWS resources that are generating the suspicious traffic.
  3. Use VPC flow logs. Publish the flow logs to a log group in Amazon CloudWatch Logs. Use CloudWatch Logs Insights to query the flow logs to identify the AWS resources that are generating the suspicious traffic.
  4. Configure the VPC to stream the network traffic directly to an Amazon Kinesis data stream. Send the data from the Kinesis data stream to an Amazon Kinesis Data Firehose delivery stream to store the data in Amazon S3. Use Amazon Athena to query the data to identify the AWS resources that are generating the suspicious traffic.

Answer(s): C



A company has its production VPC (VPC-A) in the eu-west-1 Region in Account 1. VPC-A is attached to a transit gateway (TGW-A) that is connected to an on-premises data center in Dublin, Ireland, by an AWS Direct Connect transit VIF that is configured for an AWS Direct Connect gateway. The company also has a staging VPC (VPC-B) that is attached to another transit gateway (TGW-B) in the eu-west-2 Region in Account 2.

A network engineer must implement connectivity between VPC-B and the on-premises data center in Dublin.

Which solutions will meet these requirements? (Choose two.)

  1. Configure inter-Region VPC peering between VPC-A and VPC-B. Add the required VPC peering routes.
    Add the VPC-B CIDR block in the allowed prefixes on the Direct Connect gateway association.
  2. Associate TGW-B with the Direct Connect gateway. Advertise the VPC-B CIDR block under the allowed prefixes.
  3. Configure another transit VIF on the Direct Connect connection and associate TGW-B. Advertise the VPC-B CIDR block under the allowed prefixes.
  4. Configure inter-Region transit gateway peering between TGW-A and TGW-B. Add the peering routes in the transit gateway route tables. Add both the VPC-A and the VPC-B CIDR block under the allowed prefix list in the Direct Connect gateway association.
  5. Configure an AWS Site-to-Site VPN connection over the transit VIF to TGW-B as a VPN attachment.

Answer(s): A,D



A company's network engineer is designing a hybrid DNS solution for an AWS Cloud workload. Individual teams want to manage their own DNS hostnames for their applications in their development environment. The solution must integrate the application-specific hostnames with the centrally managed DNS hostnames from the on-premises network and must provide bidirectional name resolution. The solution also must minimize management overhead.

Which combination of steps should the network engineer take to meet these requirements? (Choose three.)

  1. Use an Amazon Route 53 Resolver inbound endpoint.
  2. Modify the DHCP options set by setting a custom DNS server value.
  3. Use an Amazon Route 53 Resolver outbound endpoint.
  4. Create DNS proxy servers.
  5. Create Amazon Route 53 private hosted zones.
  6. Set up a zone transfer between Amazon Route 53 and the on-premises DNS.

Answer(s): A,C,E



A company hosts a web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The ALB is the origin in an Amazon CloudFront distribution. The company wants to implement a custom authentication system that will provide a token for its authenticated customers.

The web application must ensure that the GET/POST requests come from authenticated customers before it delivers the content. A network engineer must design a solution that gives the web application the ability to identify authorized customers.

What is the MOST operationally efficient solution that meets these requirements?

  1. Use the ALB to inspect the authorized token inside the GET/POST request payload. Use an AWS Lambda function to insert a customized header to inform the web application of an authenticated customer request.
  2. Integrate AWS WAF with the ALB to inspect the authorized token inside the GET/POST request payload.
    Configure the ALB listener to insert a customized header to inform the web application of an authenticated customer request.
  3. Use an AWS Lambda@Edge function to inspect the authorized token inside the GET/POST request payload. Use the Lambda@Edge function also to insert a customized header to inform the web application of an authenticated customer request.
  4. Set up an EC2 instance that has a third-party packet inspection tool to inspect the authorized token inside the GET/POST request payload. Configure the tool to insert a customized header to inform the web application of an authenticated customer request.
