Question 177

A user is planning to use EBS for his DB requirement. The user already has an EC2 instance running in the VPC private subnet. How can the user attach the EBS volume to a running instance?

  1. The user can create EBS in the same zone as the subnet of instance and attach that EBS to instance.
  2. It is not possible to attach an EBS to an instance running in VPC until the instance is stopped.
  3. The user can specify the same subnet while creating EBS and then attach it to a running instance.
  4. The user must create EBS within the same VPC and then attach it to a running instance.

Question 178

An organization is planning to setup a management network on the AWS VPC. The organization is trying to secure the webserver on a single VPC instance such that it allows the internet traffic as well as the back-end management traffic. The organization wants to make so that the back end management network interface can receive the SSH traffic only from a selected IP range, while the internet facing webserver will have an IP address which can receive traffic from all the internet IPs. How can the organization achieve this by running web server on a single instance?

  1. It is not possible to have two IP addresses for a single instance.
  2. The organization should create two network interfaces with the same subnet and security group to assign separate IPs to each network interface.
  3. The organization should create two network interfaces with separate subnets so one instance can have two subnets and the respective security groups for controlled access.
  4. The organization should launch an instance with two separate subnets using the same network interface which allows to have a separate CIDR as well as security groups.

Question 180

An organization is purchasing licensed software. The software license can be registered only to a specific MAC Address. The organization is going to host the software in the AWS environment. How can the organization fulfil the license requirement as the MAC address changes every time an instance is started/stopped/terminated?

  1. It is not possible to have a fixed MAC address with AWS.
  2. The organization should use VPC with the private subnet and configure the MAC address with that subnet.
  3. The organization should use VPC with an elastic network interface which will have a fixed MAC Address.
  4. The organization should use VPC since VPC allows to configure the MAC address for each EC2 instance.
