Question 163

An organization is setting up an application on AWS to have both High Availability (HA) and Disaster Recovery (DR). The organization wants to have both Recovery point objective (RPO) and Recovery time objective (RTO) of 10 minutes. Which of the below mentioned service configurations does not help the organization achieve the said RPO and RTO?

  1. Take a snapshot of the data every 10 minutes and copy it to the other region.
  2. Use an elastic IP to assign to a running instance and use Route 53 to map the user's domain with that IP.
  3. Create ELB with multi-region routing to allow automated failover when required.
  4. Use an AMI copy to keep the AMI available in other regions.

Question 164

An organization is having an application which can start and stop an EC2 instance as per schedule. The organization needs the MAC address of the instance to be registered with its software. The instance is launched in EC2-CLASSIC. How can the organization update the MAC registration every time an instance is booted?

  1. The organization should write a boot strapping script which will get the MAC address from the instance metadata and use that script to register with the application.
  2. The organization should provide a MAC address as a part of the user data. Thus, whenever the instance is booted the script assigns the fixed MAC address to that instance.
  3. The instance MAC address never changes. Thus, it is not required to register the MAC address every time.
  4. AWS never provides a MAC address to an instance; instead the instance ID is used for identifying the instance for any software registration.
