- A
Increase the shares for management traffic to 200 and reduce vMotion to 25.
Why wrong: Shares only affect proportional allocation, not guaranteed bandwidth.
- B
Set a reservation of 1 Gbps for management traffic and keep shares as they are.
Reservation provides a guaranteed minimum bandwidth for management traffic.
- C
Reduce NFS shares to 50 and increase management shares to 100.
Why wrong: Still no guarantee; management could be starved if NFS bursts.
- D
Enable the 'Limit' setting on management traffic to cap it.
Why wrong: Limiting would reduce available bandwidth, exacerbating the issue.
- E
Create a network resource pool for management traffic with a guaranteed share value.
Why wrong: NIOC does not use resource pools; it uses shares, reservation, and limit per traffic type.
Quick Answer
The answer is to set a reservation of 1 Gbps for management traffic while keeping the existing share values unchanged. This is correct because a reservation guarantees a minimum amount of bandwidth, ensuring management traffic is never starved during contention, whereas shares only determine proportional distribution of remaining bandwidth after reservations are met. On the VMware Certified Professional Data Center Virtualization VCP-DCV exam, this scenario tests your understanding that NIOC reservations provide hard guarantees for latency-sensitive traffic like management, while shares alone cannot prevent starvation under heavy load. A common trap is to increase shares, but that only improves priority proportionally without a floor, leaving management vulnerable if other traffic types consume all available bandwidth. Remember the key distinction: shares divide what is left, reservations lock in what is needed. A useful memory tip is “Reserve first, share the rest.”
VCP-DCV Configure and Manage vSphere Networking Practice Question
This VCP-DCV practice question tests your understanding of configure and manage vsphere networking. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization is using Network I/O Control (NIOC) on a distributed switch to manage bandwidth for different traffic types. The current configuration assigns 50 shares to management traffic, 50 shares to vMotion traffic, and 100 shares to NFS storage traffic. During peak hours, management traffic is suffering from high latency. The administrator must prioritize management traffic over all others while still ensuring minimum bandwidth for storage. Which action would best address the issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
Set a reservation of 1 Gbps for management traffic and keep shares as they are.
Option B is correct because setting a reservation for management traffic guarantees a minimum bandwidth, ensuring it is not starved. Option A increases shares but does not guarantee minimum bandwidth. Option C is wrong because limit would cap traffic, making it worse. Option D still lacks guarantee. Option E is not a feature of NIOC.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the VCP-DCV exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Same concept, more angles
2 more ways this is tested on VCP-DCV
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. During a period of high network contention, management traffic is starved while NFS traffic gets the most bandwidth. Which configuration change would best address the issue?
hard- A.Increase management shares to 100.
- B.Increase the NFS limit to 1000 Mbps.
- ✓ C.Set a reservation for management traffic.
- D.Enable traffic shaping on the management port group.
- E.Remove the reservation from vMotion.
Why C: Option B is correct because setting a reservation for management traffic guarantees a minimum bandwidth. Option A increases shares but does not guarantee. Option C configures shaping on the port group, not NIOC. Option D increases the NFS limit, which does not help management. Option E removes vMotion reservation, which may free bandwidth but does not guarantee management.
Variation 2. A vSphere environment uses a vSphere Distributed Switch (vDS) with 10G uplinks and Network I/O Control (NIOC) enabled. Administrators report that during peak traffic, NFS storage traffic is experiencing high latency, while other traffic types remain unaffected. The vDS has default NIOC shares and limits. Which action should be taken to prioritize NFS traffic without completely starving other traffic?
hard- A.Set a low bandwidth limit for the NFS traffic class.
- ✓ B.Increase the shares for the NFS traffic class.
- C.Set a high bandwidth reservation for the NFS traffic class.
- D.Disable Network I/O Control on the vDS.
Why B: Option D is correct because increasing the shares for the NFS system traffic class gives it a higher proportion of bandwidth during contention, without imposing a hard limit. Option A is incorrect because setting a high limit for NFS could starve other traffic if NFS uses all bandwidth. Option B is incorrect because setting a low limit for NFS would cap NFS traffic, worsening performance. Option C is incorrect because disabling NIOC removes all prioritization, making all traffic equal and not solving the issue.
