2V0-620 Question #139: Real Exam Question with Answer & Explanation
The correct answer is A: Ports on a vSS can be dynamically scaled up and down.. Ports on a vSphere Standard Switch scale dynamically, adjusting both up and down automatically based on the number of virtual machines connected, without requiring manual administrator intervention.

Question
How are ports scaled on vSphere Standard Switches (vSS)?
Options
- APorts on a vSS can be dynamically scaled up and down.
- BPorts on a vSS can only be statically scaled up or down.
- CPorts on a vSS can only be dynamically scaled down.
- DPorts on a vSS can only be dynamically scaled up.
Explanation
Ports on a vSphere Standard Switch scale dynamically, adjusting both up and down automatically based on the number of virtual machines connected, without requiring manual administrator intervention.
Common mistakes.
- B. vSS ports are not statically managed; VMware introduced dynamic port scaling precisely to eliminate the need for manual static port configuration on standard switches.
- C. vSS ports do not scale only downward; dynamic scaling works in both directions - up when demand increases and down when demand decreases.
- D. vSS ports do not scale only upward; the dynamic mechanism also reclaims unused ports by scaling down when virtual machines are powered off or disconnected.
