A European car manufacturer wants to migrate its customer-facing services and its analytics platform from two on-premises data centers to the AWS Cloud. The company has a 50-mile (80.4 km) separation between its on-premises data centers and must maintain that separation between its two locations in the cloud. The company also needs failover capabilities between the two locations in the cloud.
The company's infrastructure team creates several accounts to separate workloads and responsibilities. The company provisions resources in the eu-west-3 Region and in the eu-central-1 Region. The company selects an AWS Direct Connect Partner in each Region and requests two resilient 1 Gbps fiber connections from each provider.
The company's network engineer must establish a connection between all VPCs in the accounts and between the on-premises network and the AWS Cloud. The solution must provide access to all services in both Regions in case of network issues.
Which solution will meet these requirements?
An application team for a startup company is deploying a new multi-tier application into the AWS Cloud. The application will be hosted on a fleet of Amazon EC2 instances that run in an Auto Scaling group behind a publicly accessible Network Load Balancer (NLB). The application requires the clients to work with UDP traffic and TCP traffic.
In the near term, the application will serve only users within the same geographic location. The application team plans to extend the application to a global audience and will move the deployment to multiple AWS Regions around the world to bring the application closer to the end users. The application team wants to use the new Regions to deploy new versions of the application and wants to be able to control the amount of traffic that each Region receives during these rollouts. In addition, the application team must minimize first-byte latency and jitter (randomized delay) for the end users.
How should the application team design the network architecture for the application to meet these requirements?
An insurance company is planning the migration of workloads from its on-premises data center to the AWS Cloud. The company requires end-to-end domain name resolution. Bi-directional DNS resolution between AWS and the existing on-premises environments must be established. The workloads will be migrated into multiple VPCs. The workloads also have dependencies on each other, and not all the workloads will be migrated at the same time.

A company has developed a new web application on AWS. The application runs on Amazon Elastic Container Service (Amazon ECS) on AWS Fargate behind an Application Load Balancer (ALB) in the us-east-1 Region. The application uses Amazon Route 53 to host the DNS records for the domain. The content that is served from the website is mostly static images and files that are not updated frequently. Most of the traffic to the website from end users will originate from the United States. Some traffic will originate from Canada and Europe.
A network engineer needs to design a solution that will reduce latency for end users at the lowest cost. The solution also must ensure that all traffic is encrypted in transit until the traffic reaches the ALB.
Which solution will meet these requirements?
A company is migrating an application to the AWS Cloud. The company has successfully provisioned and tested connectivity between AWS Direct Connect and the company's on-premises data center. The application runs on Amazon EC2 instances across multiple Availability Zones. The instances are in an Auto Scaling group.
The application communicates through HTTPS to a third-party vendor's data service that is hosted at the company’s data center. The data service implements a static ACL through explicit allow listing of client IP addresses.
A network engineer must design a network solution so that the migrated application can continue to access the vendor’s data service as the application scales.
Which solution will meet these requirements with the LEAST amount of ongoing change to the vendor's allow list?
A company uses Amazon Route 53 to host a public hosted zone for example.com. A network engineer recently reduced the TTL on several records to 60 seconds. The network engineer wants to assess whether the change has increased the number of queries to Route 53 beyond the expected levels that the company identified before the change. The network engineer must obtain the number of queries that have been made to the example.com public hosted zone.
Which solution will provide this information?
A global company is establishing network connections between the company's primary and secondary data centers and a VPC. A network engineer needs to maximize resiliency and fault tolerance for the connections. The network bandwidth must be greater than 10 Gbps.
Which solution will meet these requirements MOST cost-effectively?
A network engineer is working on a private DNS design to integrate AWS workloads and on-premises resources. The AWS deployment consists of five VPCs in the eu-west-1 Region that connect to the on-premises network over AWS Direct Connect. The VPCs communicate with each other by using a transit gateway. Each VPC is associated with a private hosted zone that uses the aws.example.internal domain. The network engineer creates an Amazon Route 53 Resolver outbound endpoint in a shared services VPC and attaches the shared services VPC to the transit gateway.
The network engineer is implementing a solution for DNS resolution. Queries for hostnames that end with aws.example.internal must use the private hosted zone. Queries for hostnames that end with all other domains must be forwarded to a private on-premises DNS resolver.
Which solution will meet these requirements?
A company wants to analyze TCP internet traffic. The traffic originates from Amazon EC2 instances in the company’s VPC. The EC2 instances initiate connections through a NAT gateway.
The company wants to capture data about the traffic including source and destination IP addresses ports, and the first 8 bytes of the TCP segments of the traffic. The company needs to collect, store, and analyze all the required data points.
Which solution will meet these requirements?
A company wants to analyze TCP traffic to the internet. The traffic originates from Amazon EC2 instances in the company's VPC. The EC2 instances initiate connections through a NAT gateway. The required information includes source and destination IP addresses, ports, and the first 8 bytes of payload of TCP segments. The company needs to collect, store, and analyze all the required data points.
