This transparently distributes traffic across multiple servers by using virtual IP addresses and a shared name.
What is network load balancing?
100
Use this PowerShell cmdlet to delete a specified NLB cluster.
What is Remove-NlbCluster?
100
When you use unicast mode with a single network adapter on each node, the computer can communicate only with other computers within the same subnet. Name an alternative to being on the same subnet to perform any management tasks.
What is - you have to use a second network adapter and address?

This is the main reason for availability requirements in service level agreements between a customer and the IT department.
What is to ensure there are no misunderstandings?
100
This process occurs in an NLB cluster when a node is added or removed.
What is convergence?
200
Within each cluster, all network adapters must be either this or this.
What is multicast or unicast?
200
Use this PowerShell cmdlet to add a new dedicated IP to an NLB cluster node.
What is Add-NlbClusterNodeDip?
200
This cluster operation mode is designed to prevent the network switch from flooding with traffic.
What is IGMP Multicast?
200
Port rules do this in an NLB cluster.
What is - port rules define which incoming TCP/IP requests are balanced among the hosts in the NLB cluster?
200
The host in an NLB cluster with this priority (unique ID) handles all of the cluster’s network traffic that is not otherwise covered by a port rule.
What is the lowest priority?

This PowerShell command is used to change or set the primary IP address of the cluster.
What is Get-NlbCluster –ClusterPrimaryIP IPaddress or Set-NlbCluster –ClusterPrimaryIP IPaddress?
300
This NLB control command would be the one to use to gracefully prepare a node for a planned maintenance activity
What is drainstop?
300
When configuring a port rule for an NLB cluster with the “multiple host” filtering mode selected, this is the best option for configuring the affinity.
What is - the “Single” option will force a single cluster node to handle all client requests from a specific client?
300
The setting that is configured in an NLB cluster that determines how the member nodes are going to handle the load when the “multiple host” filter mode is used.
What is affinity?
400
The following parameters are required for this: Host parameter Cluster parameter Port rules
What is a network load balancing cluster?

. The virtual IP address that the rule should apply to ·      The TCP or UDP port range that this rule should apply to ·      The protocols that this rule should apply to, including TCP, UDP, or both ·      The filtering mode that specifies how the cluster handles traffic, which is described by the port range and the protocols.
What are options needed to configure port rules for NLB clusters?
400
This NLB control command would most likely be the best option to use to immediately prepare a node for emergency maintenance.
What is STOP?
