Refer to the exhibit. A company has extended networking from the data center to the cloud through Transit VPC. Which two statements describe the benefits of this approach? (Choose two.)
A.
Dynamic routing combined with multi-AZ deployment creates a robust network infrastructure.
B.
VPC virtual gateways provide highly available connections to virtual networks.
C.
Dedicated VPC simplifies load balancing by combining internal and external web services.
D.
VPC virtual gateways provide more secure connections to virtual networks.
E.
Dedicated VPC simplifies routing by not combining this service with other shared services.
Apologies for the wrong initial comment. The correct answers are A and E. I actually found where this question came from. It's a video from a cisco engineer and the 2 bullet points listed by the Cisco's presenter are the following:
* Simplified routing by not combining with other shared services.
* Dynamic routing combined with multi-AZ deployment creates a robust network infrastructure.
PS: it also mentions that VPC virtual gateways provide highly available connections to transit VPC virtual network appliances, not "virtual networks" so B is incorrect.

Correct answers: A & E
* Simplified routing by not combining with other shared services.
* Dynamic routing combined with multi-AZ deployment creates a robust network infrastructure.

the above link clearly states:
A. (Redundancy:) Dynamic routing combined with multi-AZ deployment creates a robust network infrastructure.
E. Dedicated VPC: simplifies routing by not combining this service with other shared services.
Question after question, we see how Cisco is absolutely terrible on coming-up with good cert exams. Instead of trying to measure technical knowledge, they play with words and semantics to make a confusing questions that is hard to read and interpret. :/
That said, to me A, B and D could be considered correct. There is a lot of room for interpretation and one engineer could say Dynamic Routing combined with Multi-AZ creates a complex architecture that is prone to error, for example, whereas another will say that it is a robust netowrk.
One engineer may trust the provider A LOT and say that VPC virtual gateways provide high availability, whereas another may have had a terrible experience and think they are not good enough. So on, and so forth.
The only 2 options that kind of conflict with one another are C and E. So definitely only one of them should be picked (if any). In that case, I would go with E.
So to me, final answer here could be any two of A, B, D and E.
Thanks Cisco, for being such a horrible certification provider!
The referenced video slide at 57 seconds appears to cover A, B and E. E is about separation of duties and benefits based upon the separation of the transit from the rest of the VPC. A and B however I consider are related by the robustness and availability. At 13 min the video goes into detail regarding the multiple tunnels between the VGW and the transit VPC providing high availability and access to multiple VPC networks. The network that B is referring to is the VPC that has the VGW. The VGW initiates the dual connections to the transit VPC CSRs and hence provides high availability to its VPC. As the dual connections could be IPSec as per the video perhaps D is also correct. Does anyone have a definitive answer if you watch the entire video?
A, E for me, transit GWs with csr100v in each availability zone creates a robust and
resilient network infrastructure, and Dedicated VPC simplifies routing and provides isolation
B is not correct, VGWs are attached to a single availability zone.
D is not correct, VPC VGWs provides the same levels of security that transit GWs basically it is an IPSEC tunnel.
It's B and E. D is incorrect because the number of secure connections is not a benefit of this solution. It is the fact that we're simplifying routing by adding a virtual infrastructure in the middle that is transparent to the branches through the VPN connection and that it is highly available.
"Benefits of the AWS Transit Gateway Solution
* The Transit Gateway solution is scalable and resilient.
* The Transit Gateway solution is a managed service. That is, high availability and monitoring is built-in, and you can track the solution using metrics like CloudWatch. (B)
* By using the Transit Gateway solution, you can simplify your network architecture, thereby reducing the operational cost. (C)
You can centrally manage your solution, including security.

it seems A and B is correct answer

@Bloody_sausage - could you check it once ?
I stay with options B and D
