Refer to the exhibit. A network engineer traces the packet flow from the Veth991 of a blade server toward the core switch. The switch reports performance issues. What is the role of the interface Eth1/7?

  1. IOM network interface
  2. fabric interconnect uplink interface
  3. IOM host interface
  4. server interface

Answer(s): B



A system administrator adds two vNICs to an existing service profile that is used to run a vSphere environment to support disjoint Layer 2 network connectivity. However, after the server is rebooted, the host is not accessible on the network. Which action resolves the issue?

  1. Build a new service profile with the desired network configuration.
  2. Remove all existing vNICs and add them in the desired order.
  3. Create a vNIC placement policy to avoid adapter renumbering.
  4. Add the disjoint Layer 2 VLANs to an existing vNIC rather than adding new vNICs.

Answer(s): C
