Objective 1.3: Differentiate Physical and Virtual Network Technologies

  • Differentiate Logical and Physical Topologies
    • Chapter 3 of Design Guide 
    • Physical
      • Network topology
      • Hosts
      • Spine and leaf
      • Oversubscription of uplinks from top of rack to spine
      • Link redundancy
    • Logical
      • How signals on physical media are passing along the network

 

  • Logical and Physical Components
    • Switches
      • Port Congiruations
      • Access vs Trunk
      • virtual distributed switches
      • NSX Logical Switch
    • Routers
      • consider amount of fixed interfaces
      • comparison made with NSX distributed logical router
      • As usual,
    • Firewalls
      • Logical vs physical
      • lack of hairpinning
    • NAT
      • NSX edge can now perform this
    • Load Balancers
      • Auto deployment
      • vs F5, Avi etc

 

  • Security Constructs
      • Service Composter
      • Endpoint Security
      • Data Security
      • Flow Monitoring
      • Actvity Monitoring
      • Distributed Firewall
      • Perimeter Firewall
    • Impact of parts being down
    • What is deployed to get each running
    • flow vs activity monitoring
    • understand prerequisites
    • Know the UI
    • 6.2 NSX provides centrally config of distributed firewall and Edge Services Gateway
