350-601 Question #399: Real Exam Question with Answer & Explanation
The correct answer is C: port binding. To configure a VDS port group for a VM to receive all frames and be mapped to a specific Layer 2 network via APIC policy, promiscuous mode must be enabled and appropriate port binding must be configured.
Question
An engineer must configure a VDS port group using APIC policy. The requirements are for the frames to be mapped to a particular Layer 2 network and for the virtual machine assigned to the port group to receive all frames passed on the virtual switch. Which two settings must be used to meet these requirements? (Choose two.)
Options
- Aforged transmits
- BVMDirectPath
- Cport binding
- Dpromiscuous mode
- EVLAN
Explanation
To configure a VDS port group for a VM to receive all frames and be mapped to a specific Layer 2 network via APIC policy, promiscuous mode must be enabled and appropriate port binding must be configured.
Common mistakes.
- A. Forged transmits is a security policy that determines whether the VM guest operating system is allowed to send frames with a MAC address different from its own, which is unrelated to receiving all frames or mapping to a Layer 2 network.
- B. VMDirectPath, also known as PCIe Passthrough, allows a VM to directly access a physical PCIe device, bypassing the hypervisor's virtual switch, which is for direct hardware access, not for general virtual switch network configuration.
- E. While VLANs are fundamental for defining a Layer 2 network, 'VLAN' itself is the network segmentation mechanism, whereas 'port binding' is the setting that associates the VM with that VLAN-configured port group, and 'promiscuous mode' handles the 'receive all frames' requirement.
