VCP-DCV Configure and Manage vSphere Networking Practice Question
Which three factors influence the behavior of Network I/O Control (NIOC) when allocating bandwidth to different traffic types? (Choose three.)
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
✓
Reservation per traffic type
Options B, C, and D are correct. Network I/O Control (NIOC) uses three configurable parameters to allocate bandwidth per traffic type: reservation (guaranteed bandwidth), shares (relative priority), and limit (maximum bandwidth). Total physical bandwidth (A) and the number of physical uplinks (E) affect overall capacity but are not configurable per traffic type, and do not directly influence NIOC's bandwidth allocation behavior.
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 total physical bandwidth
Why it's wrong here
This is a given, not a configurable factor per traffic type.
- ✓
Reservation per traffic type
Why this is correct
Reservation guarantees a minimum bandwidth.
- ✓
Shares per traffic type
Why this is correct
Shares determine proportional bandwidth distribution.
- ✓
Limit per traffic type
Why this is correct
Limit caps the maximum bandwidth.
- ✗
The number of physical uplinks
Why it's wrong here
This affects total capacity but is not a per-type factor.
