Question 312

A company wants to migrate a proprietary application from on premises to the AWS Cloud. The application implements segregation of different types of network traffic.

The application uses services that listen to multiple ports on two different IP addresses. One IP address is used for customer-facing traffic, and the other IP address is used for management traffic. The application requires the IP addresses to belong to different subnets.

How can the company deploy the application with the LEAST management overhead?

Deploy the application to Amazon Elastic Container Service (Amazon ECS). Configure two elastic network interfaces in the task definition.

Deploy the application to Amazon Elastic Container Service (Amazon ECS). Create an AWS Lambda function to attach a second elastic network interface. Use an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke the function.

Deploy the application to an Amazon EC2 instances that has a secondary elastic network interface attached. Select different subnets for each network interface.

Deploy the application to Amazon Elastic Container Service (Amazon ECS). Create an AWS Lambda function to attach a second elastic network interface. Use an AWS Step Functions workflow to invoke the function.

Question 314

A company wants to conduct a proof of concept for an SAP HANA application with a key objective to automate the provisioning of infrastructure and the application. The company operates a hybrid cloud infrastructure with AWS Direct Connect between its data center and VPC. Security policy dictates that all traffic from AWS be routed through on-premises data center firewalls. Security policy also prohibits the use of a VPC internet gateway for internet access. The company enforces use of a forward proxy server for all outbound network traffic. All resources inside the VPC are able to reach onpremises servers.

All Amazon EC2 Linux instances require package updates over the internet. However, the updates are falling and sending errors. What would cause these errors?

Inbound security groups are configured incorrectly on the EC2 instances running in the VPC.

The VPC route table does not have entries for the proxy server in the data center.

The EC2 instances are not configured to use the proxy running in the data center for traffic on TCP port 80.

The data center firewall is blocking all traffic sent from the VPC CIDR range destined for 0.0.0.0/0.

(Choose two)

Set up the VPC with an IP address range of 11.11.253.0/24.

Set up the VPC with an RFC 1918 private IP address range (e.g., 10.10.10.0/24), and set up a NAT gateway to do translation between 10.10.10.0/24 and 11.11.253.0/24 for all outbound traffic.

Set up a VPN connection between a VGW and an on-premises router, set the VGW as the default gateway for all traffic, and configure the on-premises router to forward traffic to the Internet.
