The dev account has purchased two reserved instances with instance type of m4.large in Availability Zone 1a. However, no instances are running on the dev account, but a m4.large is running in the staging account inside of availability zone 1a. Who can receive the pricing? No account will receive the reservation pricing because the reservation was purchased on the dev account and no instances that match the reservation are running in the dev account. All accounts running the m4.large will receive the pricing even if there is only one reserved instance purchase. The reserved instance pricing will still be applied because the staging account is running an instance that matches the reservation Only the primary account (the consolidated billing primary account) will receive discounted pricing if the instance is running in the primary billing account. 2 / 20 In DynamoDB, the default table size is: 10 GB 5 GB There is no table size 1 GB 3 / 20 AWS Elastic Load Balancer supports SSL termination.

You have been told to set this up on an AWS EC2 instance; however, one of the problems is that the software license has to be tied to a specific MAC address and from your experience with AWS you know that every time an instance is restarted it will almost certainly lose it’s MAC address. What would be a possible solution to this given the options below? Use a VPC with an elastic network interface that has a fixed MAC Address. Use a VPC with a private subnet for the license and a public subnet for the EC2 Make sure any EC2 Instance that you deploy has a static IP address that is mapped to the MAC address. Use a VPC with a private subnet and configure the MAC address to be tied to that subnet. 9 / 20 The company you work for has a huge amount of infrastructure built on AWS.
