Layer 3 VPN

What is a requirement for using SMB Direct?

RDMA-compatible NICs

Which Windows Server 2016 technology allows several network interfaces to work together in a group effort to provide load balancing and fault tolerance?

NIC Teaming

In datacenters, virtual networks communicate with other networks using tunneling protocols. Which of the following are commonly used protocols? (Select two.)

Network Virtualization using Generic Routing Encapsulation (NVGRE) Virtual Extensible LAN (VXLAN)

Joel has an Active Directory domain that contains multiple Hyper-V hosts that run Windows Server 2016. He plans to deploy network virtualization and centrally manage Datacenter Firewall policies. Which component must Joel install for the planned deployment?

Network controller

Which device processes software load balancing commands and distributes policies among Hyper-V hosts and other components?

Network controller

When RSS is not enabled or supported, how does the network handle traffic?

Network traffic is processed by one CPU.

Which PowerShell cmdlet creates a virtual switch with the name 'IOVSwitch' with SR-IOV enabled on the NIC named Ethernet?

New-VMSwitch "IOVSwitch" -EnableIov $True -NetAdapterName "Ethernet"

Which feature ensures a consistent stream or data, prevents data loss in the Ethernet environment, and ensures that there are no dropped frames or retransmitted traffic?

Performance Flow Control

Which type of address is used by the datacenter network that reflects the provider's physical network addressing scheme?

Provider address

Which of the following lets you set priorities to allocate bandwidth by protocol?

Quality of Service

Which method both provides security and is very good at keeping a connection so protocols that are connection-oriented, such as TCP, can maintain functionality?

RAS using IKE version 2

What feature is designed for network drivers and used to efficiently distribute incoming network traffic among multiple CPU cores?

Receive Side Scaling

What does Windows Server Gateway allow you to do?

Route traffic between virtual networks and the physical network

Which of the following is a disadvantage of software-defined networking (SDN)?

SDN standards are still being developed.

Which device listens for updates from the network controller, distributes Software Load Balancing policies, and configures Hyper-V switches?

Software Load Balancer Host Agent

Which device maps virtual IP addresses (VIPs) to dynamic IP address (DIPs) on incoming east-west traffic and forwards the traffic to the correct DIP?

Software Load Balancer MUX

Network engineers have the option of using software to configure and intelligently control the network rather than rely on the individual static configuration files that are located on each network device. Which of the following is a relatively new technology that allows network and security professionals to use software to manage, control, and make changes to a network?

Software-defined networking (SDN)

You have opted to use software-defined networking (SDN) to manage, control, and make changes to your networ. You want to be able to use software to configure and intelligently control the network, rather than rely on the individual static configuration files that are located on each network device. SDN consists of three layers: Application Layer, Control Layer, Physical Layer Which of the following describes what the SDN controller does to networking devices that comprise the Physical Layer?

The Control layer removes the control plane from networking devices and creates a single control plane.

You want to use RSS. When you search NIC properties, you do not see any options for RSS. What might be preventing you from seeing this option?

The NIC does not support RSS.

You have a server named SRV1 with Windows Server 2016. You have Hyper-V installed on SRV1. SRV1 has four network adapters that are dedicated to virtual machines. The network adapters are RDMA-enabled. You want to make sure your network connections are resilient if one or more physical NICs should fail. Which feature should you implement?

Switch Embedded Teaming

Which component can you use to manage Hyper-V hosts and all SLB components?

System Center Virtual Machine Manager

Software-defined networking (SDN) uses a controller to manage the devices. The controller is able to inventory hardware components in the network, gather network statistics, make routing decisions based on gathered data, and facilitate communication between devices from different vendors. It can also be used to make widespread configuration changes on just one device. Which of the following statements best describes an SDN controller?

The SDN controller is software.

You are in the process of setting up a virtual machine with multiple cores. You want to reduce overhead while getting packets from the physical network to your virtual machine. Which Windows Server 2016 feature will allow you to utilize more than one queue on the host adapter?

Virtual Machine Multi-Queue (VMMQ)

A virtual NIC's performance is increased because it can deliver packets from the external network directly to the virtual NIC, bypassing the management operating system. Which technology allows the NIC to do this?

Virtual Machine Queue (VMQ)

Which of the following does SR-IOV enhance to increase performance?

Virtual NICs

After reviewing the capabilities of Switch Embedded Teaming (SET) available in Windows Server 2016, you have decided to implement SET in your current system. Which of the following requirements must be met to utilize SET in your network? (Select two.)

You can group 1 to 8 physical adapters for use. All NICs must be identical and operate at the same speed.

Network Security Groups are security policies based on access control lists (ACLs). Which option best describes an ACL?
