Question

Scenario: The company needs to ensure that the provisioning traffic does NOT interfere with the exisiting PXE solution. The Provisioning Services servers will be connected to a 10 Gbps network. How does using a dedicated switch help the company secure streaming traffic?

Options

  • ADedicated VLANs ensure streaming traffic is NOT visible to other VLANs in the datacenter.
  • BDedicated switches enable streaming traffic to be encrypted with IPsec.
  • CDedicated switches allow the necessary TCP offload settings to be configured on the streaming NIC.
  • DDedicated switches enable isolation of Spanning Tree instances.

Why each option

A dedicated switch provides an isolated network path for streaming traffic, which optimizes the environment for network interface card (NIC) performance features like TCP offload. This isolation prevents network interference and ensures maximum efficiency for high-throughput streaming traffic.

ADedicated VLANs ensure streaming traffic is NOT visible to other VLANs in the datacenter.

This option describes the function and benefit of dedicated VLANs for traffic isolation, not the direct benefit of using a dedicated physical switch.

BDedicated switches enable streaming traffic to be encrypted with IPsec.

Switches primarily handle Layer 2 forwarding and do not directly enable or manage Layer 3 encryption protocols like IPsec.

CDedicated switches allow the necessary TCP offload settings to be configured on the streaming NIC.Correct

A dedicated switch ensures that streaming traffic has an uncontested network path, allowing network interface card (NIC) features such as TCP offload to operate at peak efficiency and deliver optimal performance for high-bandwidth streaming without interference.

DDedicated switches enable isolation of Spanning Tree instances.

While a dedicated switch would physically isolate its Spanning Tree Protocol (STP) domain, the isolation of STP instances is not the primary mechanism by which it secures streaming traffic performance compared to ensuring an optimal data path for NIC offload.
