A banking company is successfully operating its public mobile banking stack on AWS. The mobile banking stack is deployed in a VPC that includes private subnets and public subnets. The company is using IPv4 networking and has not deployed or supported IPv6 in the environment. The company has decided to adopt a third-party service provider's API and must integrate the API with the existing environment. The service provider’s API requires the use of IPv6. A network engineer must turn on IPv6 connectivity for the existing workload that is deployed in a private subnet. The company does not want to permit IPv6 traffic from the public internet and mandates that the company's servers must initiate all IPv6 connectivity. The network engineer turns on IPv6 in the VPC and in the private subnets. Which solution will meet these requirements?

A bank built a new version of its banking application in AWS using containers that content to an onpremises database over VPN connection. This application version requires users to also update their client application. The bank plans to deprecate the earlier client version. However, the company wants to keep supporting earlier clients through their on-premises version of the application to serve a small portion of the customers who haven’t yet upgraded. What design will allow the company to serve both newer and earlier clients in the MOST efficient way?

A company is using an Amazon CloudFront distribution that is configured with an Application Load Balancer (ALB) as an origin. A network engineer needs to implement a solution that requires all inbound traffic to the ALB to come from CloudFront. The network engineer must implement the solution at the network layer rather than in the application. Which solution will meet these requirements in the MOST operationally efficient way?

A company has an AWS Site-to-Site VPN connection between its existing VPC and on-premises network. The default DHCP options set is associated with the VPC. The company has an application that is running on an Amazon Linux 2 Amazon EC2 instance in the VPC. The application must retrieve an Amazon RDS database secret that is stored in AWS Secrets Manager through a private VPC endpoint. An on-premises application provides internal RESTful API service that can be reached by URL ( https://api.example.internal ). Two on-premises Windows DNS servers provide internal DNS resolution. The application on the EC2 instance needs to call the internal API service that is deployed in the onpremises environment. When the application on the EC2 instance attempts to call the internal API service by referring to the hostname that is assigned to the service, the call fails. When a network engineer tests the API service call from the same EC2 instance by using the API service's IP address, the call is successful. What should the network engineer do to resolve this issue and prevent the same problem from affecting other resources in the VPC?

A company's development team has created a new product recommendation web service. The web service is hosted in a VPC with a CIDR block of 192.168.224.0/19. The company has deployed the web service on Amazon EC2 instances and has configured an Auto Scaling group as the target of a Network Load Balancer (NLB). The company wants to perform testing to determine whether users who receive product recommendations spend more money than users who do not receive product recommendations. The company has a big sales event in 5 days and needs to integrate its existing production environment with the recommendation engine by then. The existing production environment is hosted in a VPC with a CIDR block of 192.168.128 0/17. A network engineer must integrate the systems by designing a solution that results in the least possible disruption to the existing environments. Which solution will meet these requirements?

A company has established connectivity between its on-premises data center in Paris, France, and the AWS Cloud by using an AWS Direct Connect connection. The company uses a transit VIF that connects the Direct Connect connection with a transit gateway that is hosted in the Europe (Paris) Region. The company hosts workloads in private subnets in several VPCs that are attached to the transit gateway. The company recently acquired another corporation that hosts workloads on premises in an office building in Tokyo, Japan. The company needs to migrate the workloads from the Tokyo office to AWS. These workloads must have access to the company's existing workloads in Paris. The company also must establish connectivity between the Tokyo office building and the Paris data center. In the Asia Pacific (Tokyo) Region, the company creates a new VPC with private subnets for migration of the workloads. The workload migration must be completed in 5 days. The workloads cannot be directly accessible from the internet. Which set of steps should a network engineer take to meet these requirements?

A company has deployed a critical application on a fleet of Amazon EC2 instances behind an Application Load Balancer. The application must always be reachable on port 443 from the public internet. The application recently had an outage that resulted from an incorrect change to the EC2 security group. A network engineer needs to automate a way to verify the network connectivity between the public internet and the EC2 instances whenever a change is made to the security group. The solution also must notify the network engineer when the change affects the connection. Which solution will meet these requirements?

A company is deploying AWS Cloud WAN with edge locations in the us-east-1 Region and the ap-southeast-2 Region. Individual AWS Cloud WAN segments are configured for the development environment, the production environment, and the shared services environment at each edge location. Many new VPCs will be deployed for the environments and will be configured as attachments to the AWS Cloud WAN core network. The company's network team wants to ensure that VPC attachments are configured for the correct segment. The network team will tag the VPC attachments by using the Environment key with a value of the corresponding environment segment name. The segment for the production environment in us-east-1 must require acceptance for attachment requests. AH other attachment requests must not require acceptance. Which solution will meet these requirements?

A company is planning to host external websites on AWS. The websites will include multiple tiers such as web servers, application logic services, and databases. The company wants to use AWS Network Firewall. AWS WAR and VPC security groups for network security. The company must ensure that the Network Firewall firewalls are deployed appropriately within relevant VPCs. The company needs the ability to centrally manage policies that are deployed to Network Firewall and AWS WAF rules. The company also needs to allow application teams to manage their own security groups while ensuring that the security groups do not allow overly permissive access. What is the MOST operationally efficient solution that meets these requirements?

Question 5

A company uses a 4 Gbps AWS Direct Connect dedicated connection with a link aggregation group (LAG) bundle to connect to five VPCs that are deployed in the us-east-1 Region. Each VPC serves a different business unit and uses its own private VIF for connectivity to the on-premises environment.

Users are reporting slowness when they access resources that are hosted on AWS.
