N10-005 Question #372: Real Exam Question with Answer & Explanation

Because the company already has a multi-layer switch (which supports both Layer 2 switching and Layer 3 routing),

Question

A small company has a single multi-layer switch. The company currently has all network devices on the same subnet but would like to switch the servers to another subnet for security reasons. The company cannot budget any more money to purchase additional hardware. Which of the following features should be used to achieve the new company requirements?

Options

  • APAT
  • BPoE
  • CVLAN
  • DQoS

Explanation

A VLAN (Virtual Local Area Network) allows a single physical switch to be logically segmented into multiple isolated broadcast domains, each acting as its own subnet. Because the company already has a multi-layer switch (which supports both Layer 2 switching and Layer 3 routing), VLANs can be created to place servers on a separate subnet from user devices - all without purchasing additional hardware. The inter-VLAN routing needed for the subnets to communicate is handled by the multi-layer switch itself. PAT is a form of NAT for address translation; PoE delivers power over Ethernet; QoS prioritizes traffic - none of these solve the subnet segmentation requirement.
