What is the purpose of a port group on a Distributed Switch?

Question

Options

• ATo enable vSAN connectivity.

Explanation

A port group on a Distributed Switch defines a logical grouping of virtual ports that share the same network configuration - including VLAN settings, security policies, traffic shaping, and teaming policies. This allows administrators to consistently apply network segmentation and policy across many virtual machines at once, making C correct.

Why the distractors are wrong:

• A - vSAN uses VMkernel ports and storage networking, not port groups as its enabling mechanism.
• B - CPU and memory allocation is handled by resource pools and VM settings, not networking constructs.
• D - Storage I/O performance is managed by Storage I/O Control (SIOC), a completely separate feature.

Memory tip: Think of a port group as a "network template stamp" - every VM plugged into it inherits the same VLAN and policy rules automatically. If it touches network traffic, it's a port group concern; if it touches compute or storage, look elsewhere.
