Q 
You are the administrator for your company network. You can use Policy-based QoS to control bandwidth costs, manage traffic, or negotiate service levels with bandwidth pro- viders or business departments. QoS policies can define priority through a Differentiated Services Code Point (DSCP) value. The DSCP applies a value (0–63) within the Type of Service (TOS) field in an IPv4 packet’s header and within the Traffic Class field in IPv6. This value provides classification at the Internet Protocol (IP) level, which routers can use to decide queuing behavior. You can also limit an application’s outbound network traffic by specifying a throttle rate. The Wi-Fi Alliance has established a certification for Wireless Multimedia (WMM) that defines four access categories (WMM_AC) for priori- tizing network traffic transmitted on a wireless network. Which group should have the highest DSCP value?
A. Background (BK)
B. Best effort (BE)
C. Video (VI)
D. Voice (VO)
A

D. In order of highest to lowest priority, the access categories are: Voice (VO), Video (VI), Best Effort (BE), and Background (BK). Voice (VO) is the highest with a DSCP range of 48–63, while Background (BK) is the lowest with a range of 8–23.

Q

You are the administrator for your company network. Your company has 10 offices. Each office has a local network that contains several Windows Server 2016 Hyper-V hosts. All of the offices are connected by high speed, low latency WAN links. What component should you install if you need to ensure that you can use QoS policies for Live Migration traffic between the offices?
A. The Canary Network Diagnostics feature
B. The Data Center Bridging feature
C. The Multipath I/O feature
D. The Network Controller server role
E. The Routing role service

A

B. You can enable and configure network QoS with the Data Center Bridging (DCB) fea- ture. QoS can help manage network traffic by configuring rules that can detect congestion or reduced bandwidth, and then to prioritize, or throttle, traffic accordingly. You can use QoS to prioritize voice and video traffic, which is sensitive to latency. DCB provides band- width allocation to specific network traffic and helps to improve Ethernet transport reliabil- ity by using flow control based on priority.

Q 
You are the administrator for your company network. You and a colleague are discussing NIC Teaming. You know that you can set up NIC Teaming by using Server Manager or PowerShell and that different configuration models are available. If you want each NIC adapter connected into a different switch, what is this configuration called?
A. Switch Dependent 
B. Switch Reliant
C. Switch Independent 
D. Switch Autonomous
A

C. With Switch Independent mode, the switch or switches to which the NIC Team mem- bers are connected are unaware of the presence of the NIC Team and do not determine how to distribute network traffic to NIC Team members. Instead, the NIC Team distributes inbound network traffic across the NIC Team members. When you use Switch Independent mode, the network traffic load is distributed based on the TransportPorts address hash as modified by the Dynamic load balancing algorithm.

D. Routing Role service

A

D. To use Border Gateway Protocol (BGP) routing, you must install the Remote Access Ser- vice (RAS) and/or the Routing Role service of the Remote Access server role on a computer or virtual machine (VM). BGP reduces the need for manual route configuration on routers because it is a dynamic routing protocol, and it automatically learns routes between sites that are connected by using site-to-site VPN connections.

37
Q

You are the administrator for your company network. You have a Windows Server 2016 Hyper-V host named Server1 that has two network adaptors named NIC1 and NIC2. Server2 has two virtual switches named vSwitch1 and vSwitch2. N1C1 connects to vSwitch1. NIC2 connects to vSwitch2. Server1 hosts a virtual machine named VM1. VM1 has two network adapters named vmNIC1 and vmNIC2. vmNIC1 connects to vSwitch1 and vmNIC2 connects to vSwitch2. What should you run on VM1 if you need to create a NIC Team on VM1?
A. $var1 = “LACP” $var2 = “Dynamic”
B. $var1 = “Static” $var2 = “HyperVPort”
C. $var1 = “SwitchIndependent” $var2 = “TransportPorts”
D. $var1 = “SwitchIndependent” $var2 = “HyperVPort”

A

C. With Switch Independent mode, the switch or switches to which the NIC Team mem- bers are connected are unaware of the presence of the NIC Team and do not determine how to distribute network traffic to NIC Team members. Instead, the NIC Team distributes inbound network traffic across the NIC Team members. When you use Switch Independent mode, the network traffic load is distributed based on the TransportPorts address hash as modified by the Dynamic load balancing algorithm.

39
Q

You are the administrator for your company network. You decide to implement Switch Embedded Teaming (SET). You and a colleague are discussing creating a new SET team. You must configure it so that you have member adapters and load balancing mode config- ured. Which load balancing mode ensures that outbound loads are distributed based on a hash of the TCP ports and IP addresses while also rebalancing loads in real time so that a given outbound flow can move back and forth between SET team members?
A. Dynamic
B. Dynamic Hyper-V C. Hyper-V Port
D. Outbound

A

A. When you create a new SET team, you must configure the member adapters and Load Balancing Mode team properties. The options for SET team Load Balancing distribution mode are Hyper-V Port and Dynamic. The options Dynamic Hyper-V and Outbound are not valid distribution modes.
The Dynamic Load Balancing Mode provides the following:
■■ Outbound—Loads are distributed based on a hash of the TCP Ports and IP addresses. Dynamic mode also re-balances loads in real time so that a given outbound flow can move back and forth between SET team members.
■■ Inbound—Loads are distributed in the same manner as the Hyper-V Port mode.

40
Q

You are the administrator for your company network. You are discussing using Switch Embedded Teaming (SET) as an alternative to NIC Teaming. What else does SET allow you to do?

44
Q 
You are the administrator of your company network. You and a colleague are discussing Receive Side Scaling (RSS). You know that it allows a system’s network adapter to spread the network processing between multiple processors. RSS has the ability to work with sys- tems that have more than how many processors?
A. 12 
B. 24 
C. 36 
D. 64
A

D. RSS has the ability to work with systems that have more than 64 processors. RSS can do this because it spreads the load across all of the processors. Since RSS can spread the network load, you end up with TCP load balancing. RSS also has the ability to load balance non-TCP traffic like UDP and multicast messages. RSS also allows an administrator to have better auditing and management capabilities.

50
Q

You are the administrator for your company network. You manage a Windows Server 2016 Software Defined Network (SDN). The network controller is installed on a three-node, domain-joined cluster of virtual machines. You need to add a new Access Control List (ACL) for the network controller to the network interface on a tenant virtual machine. The ACL will have only one rule that prevents only outbound traffic from the 10.10.10.0/24 subnet. You will run the following Windows PowerShell commands:
$ruleproperties = new-object
Microsoft.Windows.NetworkController.AclRuleProperties
$ruleproperties.SourcePortRange = “0-65535”
$ruleproperties.DestinationPortRange = “0-65535”
$ruleproperties.Action = “Deny” $ruleproperties.Priority = “100”
$ruleproperties.Type = “Outbound”
$ruleproperties.Logging = “Enabled”
What remaining properties should you add to the rule? (Choose three.)
A. $ruleproperties.DestinationAddressPrefix = “10.10.10.0/24” B. $ruleproperties.SourceAddressPrefix = “10.10.10.0/24”
C. $ruleproperties.Protocol = “ALL”
D. $ruleproperties.Protocol = “TCP”
E. $ruleproperties.DestinationAddressPrefix = “” F. $ruleproperties.SourceAddressPrefix = “”

A

B, C, E. The New-NetworkControllerAccessControlList command creates a new access control list for allowing/denying traffic to/from a particular subnet or network interface. Each access control list can contain multiple rules. In this given scenario, you will want to add:
■■ The $ruleproperties.SourceAddressPrefix to the IP address indicated as “10.10.10.0/24” as the source address
■■ The $ruleproperties.Protocol = “ALL”, which will allow all protocols
■■ The $ruleproperties.DestinationAddressPrefix = “*”, which is the wildcard and
will allow all destination addresses

Q 
You are the administrator for your company network. You and a colleague are discussing Software Defined Network (SDN) and how SDN can use Software Load Balancing (SLB) to evenly distribute network traffic between virtual network resources. There are a few terms that refer to the way that your application traffic patterns go in context of your datacenter. If applications have a pattern that sends data to other applications within the same datacen- ter or between datacenters, it is said to be what kind of pattern?
A. An East-West traffic pattern
B. An East-South traffic pattern
C. A North-South traffic pattern
D. A North-West traffic pattern
A

A. When it comes to SLB and Network Address Translation (NAT) , you may sometimes hear the terms North-South or East-West. These terms just refer to the way that your application traffic patterns go in the context of your datacenter. This question refers to “applications that send data to other applications within the same datacenter or between datacenters,” so it has an East-West traffic pattern.

52

In this question, it states that “if your organization has an older datacenter where clients simply request data from a single server,” so it has a North-South traffic pattern.

56
Q

You are the administrator for your company network. You and a colleague are discussing RAS Gateway features in Windows Server 2016. One feature:
Enables connectivity between tenant virtual networks and external networks
Is lightweight, and support is available on most network devices
Becomes an ideal choice for tunneling where encryption of data is not required
Supports Site-to-Site (S2S) tunnels, which solves the problem of forwarding between tenant virtual networks and tenant external networks using a multitenant gateway
Which feature of RAS Gateway is being discussed?
A. Generic Routing Encapsulation (GRE)
B. Dynamic Routing with Border Gateway Protocol (BGP)
C. Point-to-Site (P2S) VPN
D. Site-to-Site (S2S) VPN

A

A. Generic Routing Encapsulation (GRE)–based tunnels enable connectivity between ten- ant virtual networks and external networks. Since the GRE protocol is lightweight and sup- port for GRE is available on most network devices, it becomes an ideal choice for tunneling where encryption of data is not required. GRE support in S2S tunnels solves the problem
of forwarding between tenant virtual networks and tenant external networks using a mult- itenant gateway.

57
Q

You are the administrator for your company network. You and a colleague are discussing routing traffic across networks of a Software Defined Network (SDN) infrastructure.

Q

You are the administrator for your company network. You and a colleague are discussing Storage Quality of Service (QoS). Storage QoS allows a Hyper-V administrator to manage how virtual machines access storage throughput for Virtual Hard Disks (VHDs). Storage QoS gives an administrator the ability to guarantee which of the following?
A. That the storage throughput of a single VHD cannot adversely affect the performance of another VHD on the same host
B. That the storage throughput of a single VHD cannot adversely affect the performance of another VHD on a different host
C. That the storage throughput of multiple VHDs cannot adversely affect the perfor- mance of another VHD on the same host
D. That the storage throughput of multiple VHDs cannot adversely affect the perfor- mance of another VHD on the different hosts

A

A. Storage QoS gives an administrator the ability to guarantee that the storage throughput of a single VHD cannot adversely affect the performance of another VHD on the same host. It does this by giving administrators the ability to specify the maximum and mini- mum I/O loads based on I/O operations per second (IOPS) for each virtual disk in your virtual machines.

61
Q

You are the administrator for your company network. You have a Windows Server 2016 Hyper-V host server that contains production and test virtual machines (VMs). You plan to optimize the performance of the VMs. The following settings must be applied to the VMs:
■✓ You must set a maximum value for the input/output operations per second (IOPS) on the test VMs.
■✓ You must set a minimum value for the IOPS on the production VMs.
How should you configure the environment?
A. Create a shared virtual hard disk (VHD).
B. Enable Network Quality of Service (QoS) on all virtual machines.
C. Enable Resource Metering on the Hyper-V host server.
D. Enable Storage Quality of Service (QoS) on all virtual machines.

A

D. Storage QoS provides the ability to specify a maximum IOPS value for your virtual hard disk. An administrator can throttle the storage I/O to stop a tenant from consuming excessive storage resources that may impact another tenant. Administrators can also set a minimum IOPS value. They will be notified when the IOPS to a specified virtual hard disk is below a threshold that is needed for its optimal performance.

Q

You are the administrator for your company network. You have a Windows Server2016 server named Hyperv1, which is a Hyper-V host that hosts a virtual machine named VM1. Hyperv1 has three network adapter cards that are connected to virtual switches named Ethernet1, Ethernet2, and Ethernet3. NIC Teaming on VM1 is currently configured as follows:
Team Name: VM1 NIC Team
Member Adapters: Ethernet2 10 Gbps
Ethernet3 10 Gbps
Teaming Mode: Switch Independent
Load Balancing Mode: Address Hash
Standby Adapter: None (all adapters Active)
Primary Team Interface: VM1 NIC Team; Default VLAN
What should you do if you need to ensure that VM1 will retain access to the network if a physical network adapter card fails on Hyperv1?
A. From the properties of the NIC team on VM1, add the adapter named Ethernet1 to the NIC team.
B. From Hyper-V Manager on Hyperv1, modify the settings on VM1.
C. From PowerShell on VM1, run the Set-VmNetworkAdapterTeamMapping cmdlet.
D. From PowerShell on Hyperv1, run the Set-VmNetworkAdapterFailoverConfiguration cmdlet.
