Exam AZ-801 topic 3 question 18 discussion

i agree with neusapp on this one The questions says "which two components" (in parallel) https://learn.microsoft.com/en-us/windows-server/networking/sdn/manage/guest-clustering#example-load-balancer-configuration

Virtual machines connected to a virtual network are only permitted to use the IP addresses that Network Controller has assigned to communicate on the network. Clustering technologies that require a floating IP address, such as Microsoft Failover Clustering, require some extra steps to function correctly. The method for making the floating IP reachable is to use a Software Load Balancer (SLB) virtual IP (VIP). The software load balancer must be configured with a health probe on a port on that IP so that SLB directs traffic to the machine that currently has that IP. https://learn.microsoft.com/en-us/windows-server/networking/sdn/manage/guest-clustering#example-load-balancer-configuration

NLB and SLB

To ensure that Cluster1 can use floating IP addresses, you need to deploy the following components: A. Network Load Balancing (NLB): NLB is a Windows Server feature that provides high availability and scalability by distributing network traffic across multiple servers. It can be configured to use floating IP addresses, which are assigned to the cluster nodes as needed. E. Software Load Balancer (SLB): SLB is a feature of Software Defined Networking (SDN) in Windows Server that provides load balancing for virtual network traffic. It can also be configured to use floating IP addresses for failover scenarios. These components, NLB and SLB, enable the assignment and management of floating IP addresses for failover clusters like Cluster1.

To ensure that the failover cluster can use floating IP addresses, you should deploy the following components: A. Network Load Balancing (NLB)1: NLB is a feature of Windows Server that provides high network performance and availability by balancing network traffic among multiple servers. It can also be used to distribute network traffic to multiple IP addresses, which can be useful in a failover cluster scenario. E. Software Load Balancer (SLB): SLB is used in Azure to provide high availability and network performance to your applications. It can distribute network traffic to multiple IP addresses, which is necessary for a failover cluster that uses floating IP addresses. The method for making the floating IP reachable is to use a Software Load Balancer (SLB) virtual IP (VIP). The software load balancer must be configured with a health probe on a port on that IP so that SLB directs traffic to the machine that currently has that IP

https://learn.microsoft.com/en-us/windows-server/networking/sdn/manage/guest-clustering NLB and Network Controller SLB are used for " Azure-inspired Software Load Balancer (SLB) as a component of the Software Defined Networking (SDN) infrastructure. Use SLB instead of NLB if you are using SDN, are using non-Windows workloads, need outbound network address translation (NAT), or need Layer 3 (L3) or non-TCP based load balancing. You can continue to use NLB with Windows Server 2016 for non-SDN deployments"

Network Load Balancing (NLB): NLB is used for load balancing and providing a floating IP address for high availability. It's commonly used for failover clusters. A Software Load Balancer can also be used for load balancing and providing floating IP addresses for failover clusters. This is a more modern and software-based approach compared to NLB.
