    C & D
    As the Isolation says “Ensures” (not enforces)

    NIOC equips administrators with these capabilities:
    Isolation – Ensures traffic isolation so that a given flow will never dominate over others, preventing drops.
    Shares – Allows flexible networking capacity partitioning to help users deal when flows compete for the same resources.
    Limits – Enforce traffic bandwidth limit on the overall VDS set of dvUplinks.
    Load-based Teaming – Efficiently uses a VDS set of dvUplinks for networking capacity. IEEE 802.1p tagging – Tags outbound packets from the vSphere host for proper handling by physical network resources. – See more at: http://www.vmware.com/products/vsphere/features/network-io-control#sthash.GHssBuUA.dpuf

    I agree A, D. Load-based teaming answer confuses because it is mentioned in the online training while explaining the answer D:

    “Enforces traffic BW limit on the overal VDS set of dvUplinks and uses them efficiently for network capacity by load-based teaming.”

    correct Answer: A & C

    NIOC equips administrators with these capabilities:

    Isolation – Ensures traffic isolation so that a given flow will never dominate over others, preventing drops.

    Load-based Teaming – Efficiently uses a VDS set of dvUplinks for networking capacity.

    1. John Howell says:

      Looking at vSphere 6 documentation Center – Mentions NOTHING about load based teaming and NIOC

      vSphere Network I/O Control version 3 introduces a mechanism to reserve bandwidth for system traffic based on the capacity of the physical adapters on a host. It enables fine-grained resource control at the VM network adapter level similar to the model that you use for allocating CPU and memory resources..
      Version 3 of the Network I/O Control feature offers improved network resource reservation and allocation across the entire switch.” so we get “D.
      Enforces network bandwidth limit on the virtual distributed switch.”

      http://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/vmware_netioc_bestpractices-white-paper.pdf
      “The Network I/O Control (NetIOC) feature available in VMware® vSphere™ 4.1 (“vSphere”) addresses these challenges by introducing
      a software approach to partitioning physical network bandwidth among the different types of network traffic flows. It does so by
      providing appropriate quality of service (QoS) policies enforcing traffic isolation”
      SO “A.
      Enforces traffic isolation.”
      A, D. Where the hell is this site getting it’s “Correct” answers, they seem to be bullshit.
