Objective 6.1: Configure and Manage Logical Load Balancing Describe and understand when to use the two topologies for load balancing NSX edge LB enables net traffic to pass through multiple paths to a specific destination, to optimal resource optimization. It handles traffic up to L7, mapping eternal (or public) IP address to a set of […]
Objective 5.4: Configure and Manage Logical Routers Dynamic routing provides the necessary forwarding information between layer 2 broadcast domains, thereby allowing you to decrease layer 2 broadcast domains and improve network efficiency and scale NSX extends this intelligence to where the workloads reside for doing East-West routing. This allows more direct virtual machine to virtual […]
Objective 5.1: Create and Administer Logical Switches Given a scenario, demonstrate the proper way to add/remove a logical switch and Determine use case for and contrast the three Control Plane Modes A logical switch is distributed and can span arbitrarily large compute clusters. This allows for virtual machine mobility (vMotion) within the datacenter without limitations of […]
Objective 4.3: Upgrade Existing vCNS/NSX Implementation Based on a given upgrade scenario, identify requisite steps and components for upgrading to NSX 6.x Before you install or upgrade NSX, consider your network configuration and resources. You can install one NSX Manager per vCenter Server, one instance of Guest Introspection and Data Security per ESXi host, and […]
Objective 4.1: Configure Environment for Network Virtualization Comprehend physical infrastructure configuration for NSX Compute, Edge and Management clusters (MTU, Dynamic Routing for Edge, etc.) Physical infrastructure configuration: MTU: must be >=1600 (configure it at switch and vSwitch level). Note: quite all new switches uses have preconfigured jumbo frames (9000 bytes), check switch vendor documentation before […]
Objective 3.2: Configure and Manage vDS Policies Compare and contrast common vDS policies Virtual Switch Objects Where Policies Apply for vSphere Distributed Switch: Distributed port group –> When you apply policies on a distributed port group, the policies are propagated to all ports in the group Distributed Port –> You can apply different policies on […]
Objective 3.1: Configure and Manage vSphere Distributed Switches (vDS) Compare and contrast vDS capabilities Provides centralized management and monitoring of the networking configuration of all hosts that are associated with the switch. consists of two logical section: data plane implements the package switching, filtering,tagging, and so on management plane is the control structure that you […]
Objective 2.2: Determine Physical Infrastructure Requirements for a VMware NSX Implementation Discern management and edge cluster requirements Management Cluster Composed by including vCenter Server, NSX manager, NSX controller, Cloud Management Systems (CMS), and other shared components. Compute and memory requirements are pre-identified by the sum of the minimum supported configuration Enabling LACP is possible […]
Objective 2.1: Compare and Contrast the Benefits of Running VMware NSX on Physical Network Fabrics Fabrics Differentiate physical network topologies – Note about leaf-spine architecture With Leaf-Spine configurations, all devices are exactly the same number of segments away and contain a predictable and consistent amount of delay or latency for traveling information. This is possible […]
Objective 1.3: Differentiate Physical and Virtual Network Technologies Differentiate logical and physical topologies, components and services Servers are interconnected by a physical network that already meets the basic requirements for network virtualization –> provide IP connectivity between the physical servers. Because the vSwitch is the first hop in the data path for every packet that […]
