For high availability I will go with option D.

DDDDDDDDDDDDDD

THE ANSWER IS DDDDD

D seems the right answer to me

D. Create a Network Load Balancer backed by an Auto Scaling group with instances in multiple Availability Zones as the target.

Passed the exam on 26th June, this question was on my test.

in C, every time you add/delete a port or IP, you will have to manually change all bastions. So D ASG is the minimal efforts.

Answer is D. Got autoscaling. Answer C does not have sure fail. https://docs.aws.amazon.com/quickstart/latest/linux-bastion/architecture.html

D Load balancing and Auto Scaling often go together

D for sure

it's D

D right

For availability, auto scaling in multiple AZ is okay https://docs.aws.amazon.com/quickstart/latest/linux-bastion/architecture.html

D is good

I think that correct anwser is c. Two possibility 1. Have 2 bastion host in 2 separate AZs and put them behind the Network Load Balancer and use elastic IP 2. Put one bastion host in one AZ and use Autoscaling group to spin new bastion host in new AZ when primary bastion host fails. We will need to use script to assign EIP to newly spin bastion host. Resiliency? Resource ability to recover from damage or disruption. If I use solution 1, i use only NLB and not Autoscaling group, but if one host is unavailable, NLB, move traffic only in another alive ec2 (This is resiliency(disruption of one ec2)).
