QUESTION 71
In this section, you’ll see one or more sets of questions with the same scenario and problem.
Each question presents a unique solution to the problem, and you must determine whether the solution meets the stated goals. Any of the solutions might solve the problem.
It is also possible that none of the solutions solve the problem.
Once you answer a question in this section, you will NOT be able to return to it.
As a result, these questions will not appear in the review screen.
Note: This question is part of a series of questions that present the same scenario.
Each question in the series contains a unique solution. Determine whether the solution meets the stated goals.
Your network contains an Active Directory domain named contoso.com.
The domain contains a DNS server named Server1. All client computers run Windows 10.
On Server1, you have the following zone configuration
You need to ensure that all of the client computers in the domain perform DNSSEC validation for the fabrikam.com namespace.
Solution: From a Group Policy object (GPO) in the domain, you add a rule to the Name Resolution Policy Table (NRPT).
Does this meet the goal?
A. Yes
B. No
Answer: A
Explanation:
The NRPT stores configurations and settings that are used to deploy DNS Security Extensions (DNSSEC), and also stores information related to DirectAccess, a remote access technology.
Note: The Name Resolution Policy Table (NRPT) is a new feature available in Windows Server 2008 R2. The NRPT is a table that contains rules you can configure to specify DNS settings or special behavior for names or namespaces. When performing DNS name resolution, the DNS Client service checks the NRPT before sending a DNS query. If a DNS query or response matches an entry in the NRPT, it is handled according to settings in the policy. Queries and responses that do not match an NRPT entry are processed normally.

You have a Hyper-V host named Server1 that runs Windows Server 2016.
Server1 has a virtual machine that uses a virtual hard disK (VHD) named disk1.vhdx.
You receive the following warning message from Event Viewer:
“One or more virtual hard disks have a physical sector size that is smaller than the physical sector size of the storage on which the virtual hard disk file is located.”
You need to resolve the problem that causes the warning message.
What should you run?
A. the Mount-VHD cmdlet
B. the Diskpart command
C. the Set-VHD cmdlet
D. the Set-VM cmdlet
E. the Set-VMHost cmdlet
F. the Set-VMProcessor cmdlet
G. the Install-Windows Feature cmdlet
H. the Optimize-VHD cmdlet
Answer: C
Explanation:
Issue
One or more virtual hard disks have a physical sector size that is smaller than the physical sector size of the storage on which the virtual hard disk file is located.
Resolution
Do one of the following:
* Perform a storage migration to move the virtual hard disk to a new physical system
* Use a registry setting to enable a VHD-format virtual hard disk to report a physical sector size of 4k
* Use Windows PowerShell or WMI to enable a VHDX-format virtual hard disk to report a specific sector size
The Set-VHD cmdlet sets the ParentPath or PhysicalSectorSizeBytes properties of a virtual hard disk. The two properties must be set in separate operations.
The Set-VHD -PhysicalSectorSizeBytes parameter specifies the physical sector size, in bytes. Valid values are 512 and 4096. This parameter is supported only on a VHDX-format disk that is not attached when the operation is initiated.

QUESTION 73
You have an Active Directory domain that contains several Hyper-V hosts that run Windows Server 2016.
You plan to deploy network virtualization and to centrally manage Datacenter Firewall policies.
Which component must you install for the planned deployment?
A. the Routing role service
B. the Canary Network Diagnostics feature
C. the Network Controller server role
D. the Data Center Bridging feature
Answer: C
Explanation:
Using Windows PowerShell, the REST API, or a management application, you can use Network Controller to manage the following physical and virtual network infrastructure:
* Datacenter Firewall
This Network Controller feature allows you to configure and manage allow/deny firewall Access Control rules for your workload VMs for both East/West and North/South network traffic in your datacenter. The firewall rules are plumbed in the vSwitch port of workload VMs, and so they are distributed across your workload in the datacenter. Using the Northbound API, you can define the firewall rules for both incoming and outgoing traffic from the workload VM.
You can also configure each firewall rule to log the traffic that was allowed or denied by the rule.
* Hyper-V VMs and virtual switches
* Remote Access Service (RAS) Multitenant Gateways, Virtual Gateways, and gateway pools
* Load Balancers

QUESTION 74
You have a virtual machine named VM1 that runs Windows Server 2016.
VM1 hosts a service that requires high network throughput.
VM1 has a virtual network adapter that connects to a Hyper-V switch named vSwitch1. vSwitch1 has one network adapter. The network adapter supports Remote Direct Memory Access (RMDA), the single root I/O virtualization (SR-IOV) interface, Quality of Service (QoS), and Receive Side Scaling (RSS).
You need to ensure that the traffic from VM1 can be processed by multiple networking processors. Which Windows PowerShell command should you run in the host of VM1?
A. Set-NetAdapterRss
B. Set-NetAdapterRdma
C. Set-NetAdapterSriov
D. Set-NetAdapterQoS
Answer: A
Explanation:
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.
QUESTION 75
You have a server named Server1 that runs Windows Server 2016. Server1 is a Hyper-V host that hosts a virtual machine named VM1.
Server1 has three network adapter cards that are connected to virtual switches named vSwitch1, vSwitch2 and vSwitch3.
You configure NIC Teaming on VM1 as shown in the exhibit. (Click the Exhibit button.)
You need to ensure that VM1 will retain access to the network if a physical network adapter card fails on Server1.
What should you do?
A. From Hyper-V Manager on Server1, modify the settings of VM1.
B. From Windows PowerShell on VM1, run the Set-VmNetworkAdapterTeamMapping cmdlet.
C. From Windows PowerShell on Server1, run the Set-VmNetworkAdapterFailoverConfiguration cmdlet.
D. From Windows PowerShell on Server1, run the Set-VmSwitch cmdlet.
Answer: A
Explanation:
You can configure NIC teaming in the Guest OS; however, before NIC teaming will work in a virtual machine, you need to enable NIC teaming in the Advanced Features section of the VM settings.
QUESTION 76
