Why is the network configuration shown in the exhibit impossible?
A. A single vmnic cannot be shared by two virtual switches.
B. The MAC address of the Management Network VMkernel port is invalid.
C. Virtual machines are not allowed to run on the same virtual machine port group as the vCenter Server Virtual Appliance.
D. Virtual Machine Port Groups and VMkernel Ports are not allowed on the same virtual switch.
Correct Answer: A
Explanation/Reference:
Explanation:
Physical NICs (vmnics) cannot be shared between virtual switches. Each vmnic can only be assigned to one switch at any one time.
Incorrect Answers:
B: vmk0 is the default first VMkernel port created when you install ESXi. It uses the real, burned-in address of the physical NIC rather than a randomly generated VMware MAC address. Therefore, it cannot be invalid.
C: The vCenter Server Virtual Appliance is a virtual machine that is optimized for running vCenter Server and associated services. It can, therefore, run on the same virtual machine port group as other VMs.
D: Virtual switches can contain two connection types: VMkernel port and VM port group. You can create virtual switches with both connection types on the same switch.
