Exhibit

~ # esxcli network vswitch dvs networkresourcepool list -n vds1
Name: Management
Shares: 50
Reservation: 0
Limit: -1 (unlimited)
Name: vMotion
Shares: 50
Reservation: 500
Limit: -1 (unlimited)
Name: NFS
Shares: 100
Reservation: 0
Limit: -1 (unlimited)

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?

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 for management traffic.

Setting a reservation for management traffic guarantees a minimum amount of bandwidth, ensuring that management traffic does not get starved even under high network contention. Option A (increasing management shares) improves relative priority but does not guarantee bandwidth. Option B (increasing the NFS limit) would allocate more bandwidth to NFS, worsening the problem. Option D (enabling traffic shaping on the management port group) affects only outbound traffic on a standard switch and does not use NIOC (Network I/O Control), which is needed for reservation-based guarantees. Option E (removing the vMotion reservation) may free up bandwidth but does not guarantee management traffic receives a minimum.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Increase management shares to 100.
Why it's wrong here
Shares only affect proportional allocation; without reservation, management can still be starved.
✗
Increase the NFS limit to 1000 Mbps.
Why it's wrong here
Increasing NFS limit does not help management traffic.
✓
Set a reservation for management traffic.
Why this is correct
Reservation guarantees minimum bandwidth for management.
✗
Enable traffic shaping on the management port group.
Why it's wrong here
Traffic shaping on a port group does not affect NIOC bandwidth allocation.
✗
Remove the reservation from vMotion.
Why it's wrong here
This may free bandwidth but does not guarantee management gets it.
