Question 1 of 8
1. Question
The WildcardIT.net domain contains five Hyper-V hosts that all run Windows Server 2016.
You want to deploy network virtualization to centrally manage Datacenter Firewall policies. Which component should you install?
Correct
The Network Controller server role can be used to centrally configure and manage allow and deny firewall Access Control rules for virtual machines.
The firewall rules are configured on the vSwitch of Hyper-V hosts, allowing the rules to be distributed across many hosts

Question 2 of 8
2. Question
WCVM01 is a virtual machine running Windows Server 2016. WCVM01 hosts a service that requires high network throughput.
WCVM01 has a virtual network adapter that connects to a Hyper-V switch named vSwitch1 which has one adapter. This network adapter supports ‘Remote Direct Memory Access’ (RDMA), the single root I/O virtualization (SR-IOV) interface, Quality of Service (QoS) and Receive Side Scaling (RSS).
You need to ensure the traffic from WCVM01 can be processed by multiple networking processors. Which Windows PowerShell command should you run in the host of WCVM01?
Correct
The Set-NetAdapterRss cmdlet sets the receive side scaling (RSS) properties on a network adapter. RSS is a scalability technology that distributes the receive network traffic among multiple processors by hashing the header of the incoming packet. Without RSS Windows Server 2012/2016; network traffic is received on the first processor which can quickly reach full utilization limiting receive network throughput. Many properties can be configured using the parameters to optimize the performance of RSS. The selection of the processors to use for RSS is an important aspect of load balancing. Most of the parameters for this cmdlet help to determine the processors used by RSS

3. Question
The WildcardIT.net Active Directory domain contains Hyper-V hosts named WCVIR01 and WCVIR02 that run Widows Server 2016. Both hosts are configured to use NVGRE for network virtualization.
You have six virtual machines that are connected to an external switch. The virtual machines are configured as shown below.
To which virtual machine(s) can WCVM01 connect to?
Correct
To separate the traffic between the two virtualized networks, the GRE headers on the tunneled packets include a GRE Key that provides a unique Virtual Subnet ID for each virtualized network

Question 8 of 8
8. Question
You have two Hyper-V hosts named WCVIR01 and WCVIR02, both running Windows Server 2016 and connected to the same network.
On WCVIR01 and WCVIR02, you create an external network switch named Switch1.
You have the virtual machines shown in the below table:
All three virtual machines are connected to Switch1.
You need to prevent application in WCVM03 from being able to capture network traffic from WCVM01 and WCWM02.
The solution must ensure that WCVM01 retains network connectivity.
What should you do?
Correct
Incorrect
