A company has a legacy virtual cluster which was added to the datacenter after a small company was acquired. All VMs on the cluster use the same virtual network interface to connect to the corporate…

Question

Options

• AVisibility on the traffic between the virtual machines can impact confidentiality
• BNIC utilization can exceed 50 percent and impact availability
• CShared virtual switches can negatively impact the integrity of network packets
• DAdditional overhead from network bridging can affect availability

• B

• C

• D

Explanation

When multiple VMs with different data sensitivity levels (customer data, financial data, public web servers) all share the same virtual network interface and virtual switch, traffic between VMs traverses the same shared virtual network segment. This means a compromised or malicious VM could potentially sniff or intercept traffic from other VMs on the same virtual switch - a direct confidentiality risk. This is analogous to having all servers on a flat, unsegmented physical LAN. Options B and D relate to availability/performance, not the primary security concern of mixing data classifications on a shared network. Option C is incorrect because virtual switches do not inherently corrupt packet integrity; the concern is unauthorized visibility, not data modification.
