A company has a new AWS Direct Connect connection between its on-premises data center and the AWS Cloud. The company has created a new private VIF on this connection. However, the VIF status is DOWN.
A network engineer verifies that the physical connection status is UP and RUNNING based on information from the AWS Management Console. The network engineer checks the customer Direct Connect router and can see the ARP entry for the VLAN interface created for the private VIF at AWS.
What could be causing the private VIF to have a DOWN status?
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.
Which solution meets these requirements?
A finance company runs multiple applications on Amazon EC2 instances in two VPCs that are within a single AWS Region. The company uses one VPC for stock trading applications. The company uses the second VPC for financial applications. Both VPCs are connected to a transit gateway that is configured as a multicast router.
In the stock trading VPC, an EC2 instance that has an IP address of 10.128.10.2 sends trading data over a multicast network to the 239.10.10.10 IP address on UDP Port 5102. The company recently launched two new EC2 instances in the financial application VPC. The new EC2 instances need to receive the multicast stock trading data from the EC2 instance that is in the stock trading VPC.
Which combination of steps should the company take to meet this requirement? (Choose three.)
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?
