A company's network engineer is designing an active-passive connection to AWS from two on-premises data centers. The company has set up AWS Direct Connect connections between the on-premises data centers and AWS. From each location, the company is using a transit VIF that connects to a Direct Connect gateway that is associated with a transit gateway. The network engineer must ensure that traffic from AWS to the data centers is routed first to the primary data center. The traffic should be routed to the failover data center only in the case of an outage. Which solution will meet these requirements?

B to coltrol inbound traffic, LP has to be used!
Chose B3
Correct answer is B. TGW + DxGW (transit VIF), so the BGP community tags in use are 7224:7100/7200/7300, with 7300 is the highest priority and takes precedence, therefore to be used with primary DC.

B is the correct answer 7224:7300 has the highest priority whilst 7224:7100 has the lowest ( 7224:7X BGP communities are used for private/transit vifs) A is wrong since the priority is wrong whilst the correct tag 7X00 were used C&D are since the 7224:9X BGP communities are used for public vifs
