• Chose D1

  D is correct. A for sure is wrong. The on-premises could expand it's network with a different RFC1918 subnet. For C, you need to build another connection.

• Chose C1

  Here's why: Option C: This solution involves creating a dynamically routed VPN connection on the transit gateway and connecting it to the branch office. It then creates a propagation for the VPN attachment to the transit gateway route table. After that, it removes the existing static VPN connection.

• Chose C1

  A: Using a supernet (aggregate route) can work if the branch office subnets fit neatly within a single supernet. However, if future expansions include subnets outside the supernet, manual updates will still be required. This does not fully solve the problem of minimizing administrative overhead. B: While AWS Direct Connect offers high bandwidth and low latency, it is unnecessary for addressing the root cause (static route updates). It also involves additional costs and complexity. D: A prefix list simplifies management compared to individual static routes, but it still requires manual updates whenever new subnets are added or existing ones change. This does not eliminate administrative overhead as effectively as dynamic routing.
