What is required to achieve higher bandwidth?

Refer to the exhibit.

An organization deployed the application servers in the AWS VPC that connects to the corporate data center using Transit Gateway Connect. Demand for the applications has grown and the connection requires more bandwidth.

What is required to achieve higher bandwidth?
A . Use routable public IP addresses instead of private IP addresses for connectivity.
B . You cannot increase bandwidth the connection has a fixed limit.
C . No configuration change is required because GRE tunnels are scaled to provide higher bandwidth.
D . You add a Transit VPC between the organization’s VPCs.

Answer: C

Explanation:

Understanding Transit Gateway Connect:

Transit Gateway Connect is a feature of AWS Transit Gateway that simplifies the integration of SD-WAN networks with AWS. It uses Generic Routing Encapsulation (GRE) tunnels to facilitate this connection.

GRE Tunnels and Bandwidth:

GRE tunnels can dynamically scale to meet increasing bandwidth demands. They allow multiple tunnels between the same endpoints, which can aggregate bandwidth without requiring additional configuration.

Scaling Bandwidth with GRE:

The GRE protocol used by Transit Gateway Connect can support high bandwidth requirements by

spreading traffic across multiple tunnels. As demand grows, additional tunnels can be automatically

used to handle the increased traffic load.

Comparison with Other Options:

Option A suggests using public IP addresses, which is not relevant to bandwidth scaling.

Option B is incorrect because bandwidth can be increased through GRE scaling.

Option D suggests adding a Transit VPC, which is unnecessary for increasing bandwidth when using

Transit Gateway Connect.
