70-740 Exam - Question 127

You have an Active Directory domain named contoso.com.

The computers in contoso.com are installed by using Windows Deployment Services.

You have a server named Server1 that runs Windows Server 2016 and is a member of contoso.com. Server1 has the Hyper-V role installed. Virtual machines on

Server1 are connected to an external switch named Switch1.

You create a virtual machine named VM1 on Server1 by running the following cmdlets.

You need to ensure that you can install the operating system on VM1 by using Windows Deployment Services.

What should you do?

parameter of Switch1.

B. Add a SCSI controller to VM1.

C. Add a legacy network adapter to VM1.

parameter of Switch1.

Show Answer
Correct Answer:

To ensure that you can install the operating system on VM1 by using Windows Deployment Services (WDS), you should add a legacy network adapter to VM1. This is because a legacy network adapter is required for PXE booting, which is typically used by WDS to deploy operating systems over the network. Generation 1 virtual machines, which use VHD files and IDE controllers, necessitate the use of a legacy network adapter for network-based OS installations. Thus, the correct answer is to add a legacy network adapter to VM1.

Two Types of Hyper-V Virtual Network Adapters Hyper-V provides two types of virtual network adapters. Legacy Network Adapter: The legacy network adapter is only available for generation 1 virtual machines. It is an emulated device, meaning that Hyper-V creates a complete digital reconstruction of a common, basic physical network adapter. This adapter type exists for those situations in which there is no way for a particular guest to load the standard Hyper-V network adapter. In most cases, this is for PXE booting Generation 1 virtual machines. Any other cases would involve unsupported operating systems that have no driver for the standard virtual adapter. This adapter is locked at about 100Mbps speed and requires a comparatively high amount of CPU processing, so avoid using it in situations that do not strictly require it. [Synthetic] Network Adapter: Usually only named as a “Network Adapter”, Hyper-V’s synthetic network adapter is a connection between Hyper-V’s VMBus or an IOV Virtual Function and the virtual machine or management operating system. It is substantially faster than the legacy network adapter. Iets using a VHD (so older volume), so if its gen1 VM --> legacy nic

It is possible to know the generation through the disk file. VHD = Generation 1 | VHDX = Generation 2.
