VCP-VVF Troubleshoot And Optimize Practice Question
An administrator is troubleshooting a virtual machine network throughput issue on a vSphere Distributed Switch (vDS). The VM has a 10GbE requirement, but throughput tests show it is capped. Upon checking the vDS port group, Traffic Shaping is enabled. What does the Traffic Shaping policy control?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It enforces average bandwidth, peak bandwidth, and burst size limits on traffic flowing through the port group.
Traffic shaping on a vDS port group allows administrators to limit the average bandwidth, peak bandwidth, and burst size for inbound or outbound traffic on port groups or uplinks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It prioritizes voice and video packets using DSCP tagging.
Why it's wrong here
QoS tagging handles packet marking, whereas traffic shaping enforces bandwidth limits.
- ✓
It enforces average bandwidth, peak bandwidth, and burst size limits on traffic flowing through the port group.
Why this is correct
Traffic shaping acts as a rate limiter, restricting bandwidth consumption to defined thresholds.
- ✗
It mirrors port traffic to a designated analyzer VM for packet capture.
Why it's wrong here
Port mirroring (RSPAN/ERSPAN) handles traffic duplication for analysis.
- ✗
It automatically load-balances traffic across physical uplinks using IP hash.
Why it's wrong here
Uplink teaming policies control load balancing, not traffic shaping.
