VCP-DCV Configure and Manage vSphere Networking Practice Question
A VM experiences high packet loss during peak hours. The VM is connected to a distributed switch port group with a traffic shaping policy: average bandwidth 100 Mbps, peak bandwidth 200 Mbps, burst size 50 KB. What is the most likely cause?
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
✓
The burst size is too small, causing packets to be dropped when burst traffic exceeds the average.
Traffic shaping allows sustained traffic up to the average bandwidth (100 Mbps) and only permits bursts up to the peak bandwidth (200 Mbps) within the configured burst size. If the burst size is too small, burst traffic above the average during peak hours will be dropped, causing packet loss. The peak bandwidth limit is not necessarily being exceeded, a disabled policy would remove these shaping drops, and while a physical uplink slower than 200 Mbps could cause loss, the most likely cause given the configured policy and peak-hour burst behavior is the too-small burst size.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The peak bandwidth limit is being exceeded.
Why it's wrong here
Peak is 200 Mbps; if traffic exceeds that, drops would occur, but burst size is more likely.
- ✓
The burst size is too small, causing packets to be dropped when burst traffic exceeds the average.
Why this is correct
With 50 KB burst, sustained bursts above average cause drops.
- ✗
The traffic shaping policy is disabled.
Why it's wrong here
If disabled, no shaping occurs, so no packet loss from shaping.
- ✗
The physical uplink speed is less than 200 Mbps.
Why it's wrong here
Uplinks are typically 1 Gbps or faster.
