Exam ANS-C00 topic 1 question 242 discussion

Exam question from Amazon's ANS-C00
Question #: 242
Topic #: 1
[All ANS-C00 Questions]

You are your company's AWS cloud architect. You have created a VPC topology that consists of 3 VPCs. You have a centralised VPC (VPC-Shared) that provides shared services to the remaining 2 departmental dedicated VPCs (VPC-Dept1 and VPC-Dept2). The centralised VPC is VPC peered to both of the departmental VPCs, that is a VPC peering connection exists between VPC-Shared and VPC-Dept1, and a VPC peering connection exists between VPC-Shared and VPC-Dept2.
Select the correct option from the list below.

  • A. Network traffic is possible between VPC-Shared instances and VPC-Dept1 and VPC-Dept2 instances as long as the appropriate routes and security groups are in place, but only for communication that is initiated from VPC1-Shared instances as the default peering bi-directional communication flag has been disabled.
  • B. Instances within VPC-Dept1 can communicate directly with instances in VPC-Shared, as long as the appropriate routes and security groups are in place, and vice versa regardless of who initiates communication
  • C. All network communication remains blocked between all VPCs until the respective peering bi-directional communication flags are set to the appropriate setting that allows traffic to flow.
  • D. Network traffic is possible between VPC-Shared instances and VPC-Dept1 and VPC-Dept2 instances as long as the appropriate routes and security groups are in place, but only for communication that is initiated from VPC1-Shared instances as the default peering bi-directional communication flag has been enabled.

Suggested Answer: B 🗳️
Answers A, C and D are incorrect answers as they reference a non-existing setting - there is no such thing as a "default peering bi-directional communication flag".
