A company has set up an IPsec tunnel between its AWS environment and its on-premises data center. The tunnel is reporting as UP, but the Amazon EC2 instances are not able to ping any on-premises resources.
What should a SysOps administrator do to resolve this issue?
A. Create a new inbound rule on the EC2 instances’ security groups to allow ICMP traffic from the on-premises CIDR.
B. Create a peering connection between the IPsec tunnel and the subnet of the EC2 instances.
C. Enable route propagation for the virtual private gateway in the route table that is assigned to the subnet of the EC2 instances.
D. Modify the VPC’s DHCP options set. Add the IPsec tunnel to the VPN section.
