ANS-C01 Exam
A company is planning to use an AWS Transit Gateway hub and spoke architecture to migrate to AWS. The current on-premises multi-protocol label switching (MPLS) network has strict controls that enforce network segmentation by using MPLS VPNs. The company has provisioned two 10 Gbps AWS Direct Connect connections to provide resilient, high-speed, low-latency connectivity to AWS.
A security engineer needs to apply the concept of network segmentation to the AWS environment to ensure that virtual routing and forwarding (VRF) is logically separated for each of the company's software development environments. The number of MPLS VPNs will increase in the future. On-premises MPLS VPNs will have overlapping address space. The company's AWS network design must support overlapping address space for the VPNs.
Which solution will meet these requirements with the LEAST operational overhead?
A company's network engineer is configuring an AWS Site-to-Site VPN connection between a transit gateway and the company's on-premises network. The Site-to-Site VPN connection is configured to use BGP over two tunnels in active/active mode with equal-cost multi-path (ECMP) routing activated on the transit gateway.
When the network engineer attempts to send traffic from the on-premises network to an Amazon EC2 instance, traffic is sent over the first tunnel. However, return traffic is received over the second tunnel and is dropped at the customer gateway. The network engineer must resolve this issue without reducing the overall VPN bandwidth.
Which solution will meet these requirements?
A company plans to run a computationally intensive data processing application on AWS. The data is highly sensitive. The VPC must have no direct internet access, and the company has applied strict network security to control access.
Data scientists will transfer data from the company's on-premises data center to the instances by using an AWS Site-to-Site VPN connection. The on-premises data center uses the network range 172.31.0.0/20 and will use the network range 172.31.16.0/20 in the application VPC.
The data scientists report that they can start new instances of the application but that they cannot transfer any data from the on-premises data center. A network engineer enables VPC flow logs and sends a ping to one of the instances to test reachability. The flow logs show the following:

The network engineer must recommend a solution that will give the data scientists the ability to transfer data from the on-premises data center.
