PCCET Question #26: Real Exam Question with Answer & Explanation

Question

Which option describes the "selective network security virtualization" phase of incrementally transforming data centers?

Options

• Aduring the selective network security virtualization phase, all intra-host communication paths are
• Bduring the selective network security virtualization phase, all intra-host traffic is forwarded to a
• Cduring the selective network security virtualization phase, all intra-host traffic is encapsulated and
• Dduring the selective network security virtualization phase, all intra-host traffic is load balanced

Explanation

In the context of incrementally transforming data centers (as described in VMware NSX documentation), the 'selective network security virtualization' phase is defined by securing intra-host communication paths - that is, east-west traffic between virtual machines on the same physical host. In this phase, virtual firewalls and security services are applied to selected intra-host traffic flows without requiring all traffic to be redirected externally. The other options describe different phases: encapsulating all traffic corresponds to full virtualization phases, load balancing and forwarding to external appliances describe earlier or different transformation stages.
