Microsoft 70-410 - Configuring Servers

These are study notes for Microsoft 70-410 dealing with Servers and Hyper-V. This is again from the google spreadsheet here.


Port mirroringmonitors traffic at a VM level
Network Adapter Meteringshow how much bandwidth is used by a specific VM, done by ACLs
PVLAN in promiscuous modecommunicates with all ports in the same VLAN
PVLAN in community modecommunicates with all ports in the same VLAN and the same community
PVLAN in isolated modecommunicates with promisicuous ports on the same VLAN
vRSSvirtual Recieve side scaling - offloads network traffic to processors, so to increase bandwidth, increase cores
SR-IOVSingle Root I/O Virtualization - allows network traffic to bypass Hyper-V switch to improve performance. Can't be used with NIC Teaming. Offloads traffic from CPU's to physical adapter
NIC Teamingdistributes traffic over multiple adapters. implemented in Host OS, not Guest but can't be used with SR-IOV, IF using you need to create a vswitch that uses the team, To enable for the VM, you need to change an advanced feature or it doesn't use.
Switch independent Teaming modeused if no teaming is supported on a switch
Static Teaming Nic teaming modeplugged into the same switch
LACPplugged into same switch and uses the LACP protocol to automatically configure teaming
generation 2 VMrequires 2012 R2, supports PXE boot, virtual SCSI device and Secure boot
Windows Filtering Platform (WFP)filters and modifies TCP/IP packets in realtime enabled by default on new virtual switches
virutal Fibre Channela virtual adapter at the VM level that always access to a SAN LUN
emulated SCSI controllercan be used to attach VHDs to a VM
Host Bus Adapter (HBA)added to the host and is the mechanism that allows support of the virtual fibre channel
Offloaded Data Transferfeature in 2012 to enable more efficient processing of large stat transfers, requires a vhd on supported hardware and mounted as either virtual scsi or pass through
VirtualSubnetIDfunctions as a broadcast domain similar to a VLAN. 0 = cleared, valid ID's are in the range of 4096 and 16777215
NUMA TopologyNon-Uniform Memory Access, Is a hyper-v feature that is not compatabile with dynaminc Memory. It allows a vm to optimize assignment of virtual RAM and VCPUs but also requires NUMA aware services like SQL.It ties the vCPU and memory to the physical nodes where it is effective.
Enhanced Session ModeEnabled on the host to do things like allow redirection of local devices and resources from computer running the virtual machine connection
Virtual SwitchHost level virtual switch management, includes External, Internal, and Private
Access Based Enumeration (ABE)will only display the available files and folders to a user based on their rights
VMChimneyA Hyper-V feature that can be used to offload external virtual network adapters to a physical network adapter
Sync ClockHandles Hyper-V guest time syncronization to fight drift with the time synchronization intergration service
Web Service ScannersSupports network connected image scanners and printers. Uses WSD(Web Services for Devices) Scan driver and the Windows Image Acquistion (WIA)
Powershell Web Access GatewayA feature that gives you acess to power via a web browser portal. It is a role that can be added and and also requires a web server role installed. After installed, you need to add an authorization rule.
