Exam 70-740 topic 1 question 43 discussion

Actual exam question from Microsoft's 70-740

Question #: 43
Topic #: 1

DRAG DROP -
You are planning the configuration of a virtual network switch for a Hyper-V environment. The environment will contain the following Hyper-V hosts:
- A server named Server1 will have 10 virtual machines that must be able to communicate with each other. The virtual machines must be prevented from communicating with Server1 and all other servers on the corporate network.
- A two-node failover cluster named Cluster1 will have 20 virtual machines. The virtual machines will run on both nodes. Hyper-V hosts on the corporate network must be able to connect to the virtual machines.
Which type of virtual switch should you select for each Hyper-V host? To answer, drag the appropriate virtual switch types to the correct hosts. Each virtual switch type must be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

I wasn't sure about the External type on the 20 vm's on Cluster1, but the corporate network is external to the Hyper-V host. Answer seems to be correct. https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v-virtual-switch/hyper-v-virtual-switch

External Gives virtual machines access to a physical network to communicate with servers and clients on an external network. Allows virtual machines on the same Hyper-V server to communicate with each other. Internal Allows communication between virtual machines on the same Hyper-V server, and between the virtual machines and the management host operating system. Private Only allows communication between virtual machines on the same Hyper-V server. A private network is isolated from all external network traffic on the Hyper-V server. This type of network is useful when you must create an isolated networking environment, like an isolated test domain.

The 10 virtual machines must be prevented from communicating with Server1 -- must be Internal

Internal would allow communication with the host so that's wrong. Please read this. https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/get-started/create-a-virtual-switch-for-hyper-v-virtual-machines

Yeah, reading carefully is important. It says the virtual machines are to be PREVENTED from communicating with the HOST. Internal is VMs communicating with Host. Private is VMs communicating with each other ONLY. External is VMs with Host, and Other VMs and Host's

For "20 virtual machines on Cluster1", I think "Internal" is correct. I understand the condition of this question as follow. 1)Hyper-V hosts must be able to connect to the virtual machines. 2)The corporate network isn't needed to connect to the virtual machines.

The given answer is correct, read the question carefully.....the hyper-v host on the corporate network. emphasis on the corporate network. Communication between the virtual machines and Hyper-v hosts on the corporate network is external. Communication between the virtual machines alone is private.
