Question

Simon was asked to create three Linux virtual machines to host the company's new sales application and database server. He is going to be using the company's cloud service provider and was given the 10.20.30.0/30 subnet to put them on. He immediately tells the person giving him this task that he cannot do what is asked of him. Why?

a. The web server needs a public IP address.
b. The /30 subnet is not large enough for 3 virtual machines.
c. Linux will not run as a virtual machine.
d. The cloud service provider does not allow private IP addresses to be assigned to virtual machines.

Answer 1

Simon cannot create three Linux virtual machines using the given subnet because it is too small. He needs a larger subnet to accommodate the virtual machines.

The claim that the cloud service provider does not allow private IP addresses is incorrect.

Therefore, the correct answer is: option b. The /30 subnet is not large enough for 3 virtual machines.

Step-by-step explanation:

Virtual machines support legacy applications, reducing the cost of migrating to a new operating system.

Simon cannot create three Linux virtual machines to host the company's new sales application and database server using the given 10.20.30.0/30 subnet because the /30 subnet only allows for a maximum of two usable IP addresses.

This is because the /30 subnet has a network address, a broadcast address, and only two usable host addresses. Simon would need a larger subnet, such as a /29, which provides 8 usable IP addresses, to accommodate the three virtual machines.

In addition, the statement that the cloud service provider does not allow private IP addresses to be assigned to virtual machines is not true. Cloud service providers commonly use private IP addresses for virtual machines, and the use of public IP addresses is typically optional or customizable.
