An enterprise network administrator is deploying a virtualized server environment using a Type 1 hypervisor to host multiple virtual machines across separate VLANs. Which two statements accurately describe the operational mechanics of the virtual switch (vSwitch) and hypervisor architecture in this scenario? (Select two.)

  1. Intra-host traffic between virtual machines on the same VLAN is switched internally by the vSwitch without egressing through physical network interface cards.Cevap
  2. B
    The host operating system intercepts all incoming frames from physical interface cards before passing them to the hypervisor kernel for vSwitch processing.
  3. The vSwitch can perform IEEE 802.1Q VLAN tagging on virtual machine frames before sending them across physical uplinks to trunk ports on the physical switch.Cevap
  4. D
    The vSwitch participates fully in Spanning Tree Protocol (STP) bridge protocol data unit (BPDU) exchanges with physical switches to prevent Layer 2 loops.

Cevap

Intra-host traffic between virtual machines on the same VLAN is switched internally by the vSwitch without egressing through physical network interface cards, AND the vSwitch can perform IEEE 802.1Q VLAN tagging on virtual machine frames before sending them across physical uplinks to trunk ports on the physical switch.
In Type 1 hypervisor architectures, intra-host traffic between co-located virtual machines on the same virtual switch stays within host software memory without exiting to the physical network interface cards. Additionally, virtual switches can tag frames with IEEE 802.1Q VLAN headers before sending them over physical uplink interfaces connected to physical switch trunk ports.

Adım Adım Çözüm

1
Analyze the architecture of a Type 1 hypervisor and vSwitch frame forwarding.
A Type 1 hypervisor operates directly on bare-metal hardware. The vSwitch handles Layer 2 frame forwarding within the hypervisor software kernel.
Understanding bare-metal execution clarifies that there is no general-purpose host OS beneath the hypervisor to handle network I/O.
2
Evaluate intra-host virtual machine traffic paths.
Frames sent between VMs connected to the same vSwitch and VLAN are switched directly within server memory.
Frames only hit physical network interface card (pNIC) uplinks when destined for external network devices.
3
Determine VLAN tagging capabilities and loop prevention mechanics.
vSwitches encapsulate frames with 802.1Q tags for trunk traffic and rely on non-STP forwarding rules (such as prohibiting forwarding between physical uplinks) to avoid loops.
Standard vSwitches do not process or generate Spanning Tree Protocol BPDUs.
