You have 2 VPCs, VPC A and VPC
B. Both the VPCs have been peered. You have configured the route tables in VPC A so that traffic can flow from VPCA to VPCB. You try to ping an instance in VPCB from VPCA, but are unable to do so. You have confirmed that the NACLs and Security Groups have been configured properly. What could be the reason for this issue?

Answer options:

A.The VPC’s have overlapping CIDR blocks.
B.Security Groups don’t work in peered VPCs. Hence the requests will not work.
C.NACLs don’t work in peered VPCs. Hence the requests will not work.
D.The route tables in VPCB have not been configured.
