You are managing a VPC with 4 AZs. There is a load balancer managing the public accessibility to your servers. You have a secondary ENI with a private IPv4 address on an instance that is serving public web traffic. Your server communicates over private addresses to a database in another subnet. Security is a major concern for your company and whitelisting is in effect.

You have to bring the web server down for maintenance, what two things should you do? (Choose two.)

  • Reboot the instance.
  • Move the ENI from one server to the other.
  • Associate the new ENI with the database security group. 
  • Configure a secondary ENI on the standby instance.

Explanation:
You must configure a secondary ENI on the standby instance with an IP address that can access the data subnet. This may require modification of the security group for the database.
