Question No : 1
HOTSPOT
You deploy Microsoft System Center Virtual Machine Manager (SCVMM) and System Center Configuration Manager in an Active Directory Domain Services (AD DS) domain.
You must deploy a Software Defined Networking (SDN) network controller.
You need to create the required AD DS security groups for management users and network controller clients.
Which members should you add to each group? To answer, select the appropriate options in the answer
area. NOTE: Each correct selection is worth one point.



正解:


Explanation:

Question No : 2
You manage a Microsoft Hyper-V host server that has several high-speed physical network adapters.
You need to attach a physical network adapter directly to a virtual machine (VM).
What should you do first?

正解:

Question No : 3
You manage Microsoft System Center Virtual Machine Manager (SCVMM).
You need to block specific packets on the virtual switch.
Which two types of virtual switch extensions can you use? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

正解:
Explanation:
A Hyper-V extensible switch filtering extension can inspect, modify, and insert packets into the extensible switch data path. Based on extensible switch port and switch policy settings, the extension can drop a packet or exclude its delivery to one or more destination ports. A forwarding extension has the same capabilities as a filtering extension, but is responsible for performing the core packet forwarding and filtering tasks of the extensible switch.

Question No : 4
You manage virtual machine (VM) workloads in an environment that includes the following objects:
- an IP address pool
- a software load balancer (SLB) object
- an SLB rule
- a public VIP address
You monitor network traffic logs and observe that a VM does not service requests for the VIP address.
You need to configure the virtual network so that traffic is not sent to a VM that is unavailable.
What should you do?

Question No : 5
You administer the Microsoft System Center Virtual Machine Manager (SCVMM) infrastructure for an organization. You deploy a software load balancer (SLB).
You need to create a health probe to verify that the VIP pool members are healthy.
Which health probe response code should you identify?

正解:
Explanation:
An HTTP health probe should return a response code of 200 to indicate a healthy status.

Question No : 6
DRAG DROP You manage Microsoft System Center Virtual Machine Manager (SCVMM). You plan to implement software load balancer (SLB) on Microsoft Hyper-V host servers by using an SLB Multiplexer (MUX).
You identify the following requirements:
- Redirect all inbound traffic to the MUX.
- Ensure that all outbound network traffic bypasses the MUX.
You need to configure the environment.
Which components should you implement? To answer, drag the appropriate components to the correct
traffic directions. Each component may 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. NOTE: Each correct selection is worth one point.



正解:


Explanation:
BGP Enabled Router The BGP router performs the following actions for SLB.
- Routes inbound traffic to the MUX using ECMP.
- For outbound network traffic, uses the route provided by the host.
- Listens for route updates for VIPs from SLB MUX.
- Removes SLB MUXes from the SLB rotation if Keep Alive fails.
The SDN enabled Hyper-V Virtual Switch performs the following actions for SLB.
- Processes the data path for SLB.
- Receives inbound network traffic from the MUX.
- Bypasses the MUX for outbound network traffic, sending it to the router using DSR.
- Runs on Nano Server instances of Hyper-V.

Question No : 7
You manage Microsoft System Center Virtual Machine Manager (SCVMM). You plan to implement a software load balancer (SLB) Multiplexer (MUX).
You need to configure the Microsoft Hyper-V host servers to host the MUX.
What should you do?

正解:
Explanation:
You can use System Center to deploy SLB MUXs and to install SLB Host Agents on computers that are running Windows Server 2016 Technical Preview and Hyper-V. When you deploy SLB, you must use System Center, Windows PowerShell, or another management application to deploy the SLB Host Agent on every Hyper-V host computer.

Question No : 8
You deploy a Microsoft Hyper-V host server and install the Network Controller role.
You need to modify the application settings of the Network Controller.
Which Windows PowerShell cmdlet should you run?

正解:
Explanation:
The Set-NetworkController cmdlet sets network controller application settings.

Question No : 9
HOTSPOT
А Microsoft Hyper-V host has a network interface card (NIC) named NIC1 that supports Remote Direct
Memory Access (RDMA). You plan to install a second NIC at a later date. The Hyper-V host must have a virtual switch named vSwitch1. Switch Embedded Teaming (SET) must be enabled on the NIC.
You need to ensure that you can use the same virtual switch when you add the second NIC.
How should you complete the Windows PowerShell command? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.



正解:


Explanation:
The New-VMSwitch cmdlet creates a new virtual switch on one or more virtual machine hosts. The C EnableEmbeddedTeaming parameter specifies whether this cmdlet enables teaming for the virtual switch.

Question No : 10
You administer Microsoft System Center Virtual Machine Manager (SCVMM).
You need to access the Network Controller diagnostic logs.
Where should you view the logs?

正解:
Explanation:
Logging is automatically enabled when you install the Network Controller cluster using the Install-NetworkControllerCluster cmdlet. By default, the logs are collected locally on the Network Controller nodes at %systemdrive%\SDNDiagnostics.
