VCP-DCV Configure and Manage vSphere Networking Practice Question
Exhibit
esxcli network vswitch standard list
VSwitchName: vSwitch0
Portgroup Name: Management Network
VLAN ID: 0
Active uplinks: vmnic0
Standby uplinks: vmnic1
Portgroup Name: VM Network
VLAN ID: 100
Active uplinks: vmnic0
Standby uplinks: vmnic1
VSwitchName: vSwitch1
Portgroup Name: Storage Network
VLAN ID: 200
Active uplinks: vmnic2
Standby uplinks: vmnic3Refer to the exhibit. A virtual machine on the VM Network is experiencing intermittent connectivity. The administrator notices that vmnic0 is saturated. Which action would improve performance without causing a single point of failure?
⚠ Common exam trap
VCP-DCV often tests the misconception that simply changing the active uplink or increasing MTU will solve saturation, when the real solution requires dynamic load balancing across multiple uplinks without sacrificing redundancy.
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
✓
Configure load-based teaming on vSwitch0 for the VM Network portgroup.
Load-based teaming (LBT) on vSwitch0 dynamically balances VM traffic across all active uplinks based on real-time utilization, so vmnic0's load is shared with vmnic1, relieving saturation. It also maintains redundancy because both uplinks remain active; if one fails, the other takes over. This directly addresses the intermittent connectivity caused by vmnic0 saturation without introducing a single point of failure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change the active uplinks for VM Network to vmnic1 only.
Why it's wrong here
Pinning VM Network to vmnic1 alone moves all traffic onto a single uplink, creating exactly the single point of failure the question forbids. It is tempting because it does relieve the saturated vmnic0, and manual active/standby failover is legitimate for isolating specific port groups, but here it sacrifices redundancy rather than adding capacity.
- ✗
Increase the MTU on vSwitch0 to 9000.
Why it's wrong here
Raising the MTU to 9000 jumbo frames reduces per-packet overhead but does nothing to relieve a saturated physical uplink, and it can break connectivity where intermediate devices lack jumbo support. It is tempting because jumbo frames genuinely cut CPU and overhead on storage or vMotion traffic, but that is a throughput-efficiency measure, not a fix for an oversubscribed vmnic.
- ✓
Configure load-based teaming on vSwitch0 for the VM Network portgroup.
Why this is correct
Load-based teaming distributes traffic across physical uplinks according to current load, relieving the saturated vmnic0 while retaining multiple adapters so no single NIC becomes a point of failure. Route-based policies would not balance the existing flows causing saturation.
- ✗
Move the VM Network to vSwitch1.
Why it's wrong here
Moving the VM Network to vSwitch1 requires a physical uplink; with only vmnic0 present, that vSwitch has no uplink, so the network loses connectivity entirely. It is tempting because spreading traffic across vSwitches reduces contention, and would be correct when a second physical NIC is available.
