Question 190 of 498
VCP-DCV Configure and Manage vSphere Networking Practice Question
A VM on a vSphere Distributed Switch is experiencing intermittent connectivity drops. The administrator checks the vDS health check and sees no errors. The physical switch logs show no issues. The VM is on a port group with VLAN 200. The administrator runs a ping from the VM to the gateway and notices packet loss. What should the administrator investigate next?
⚠ Common exam trap
It's easy for candidates to assume intermittent connectivity must be a VM firewall or DNS issue, overlooking the NIC teaming failover order as a primary cause of packet loss on a vDS when physical and vDS health checks show no errors.

Correct answer & explanation
✓
Review the NIC teaming failover order and ensure active uplinks are up.
Intermittent connectivity drops on a VM connected to a vDS, despite no errors on the vDS health check or physical switch logs, often point to a NIC teaming misconfiguration. If the active uplinks are not properly set or one uplink is down, the VM traffic may fail over to a standby or unused uplink, causing packet loss. Verifying the teaming failover order and ensuring all active uplinks are operational directly addresses this common cause of intermittent drops.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Verify the VMkernel port configuration
Why it's wrong here
VMkernel is for host management, not VM traffic.
- ✗
Check the VM's firewall settings
Why it's wrong here
Firewall would cause consistent drop, not intermittent.
- ✗
Check DNS resolution for the gateway
Why it's wrong here
Ping uses IP, not DNS.
- ✓
Review the NIC teaming failover order and ensure active uplinks are up.
Why this is correct
Intermittent drops can be caused by failover events.

Same concept, more angles
1 more way 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. A network administrator notices that all traffic from two VMs connected to the same standard switch port group is going through the same physical uplink, causing congestion. The teaming policy is set to Route based on originating virtual port. What change should the administrator make to distribute traffic more evenly?
easy- ✓ A.Change teaming policy to Route based on IP hash.
- B.Increase the number of uplinks to 4.
- C.Enable LACP on the standard switch.
- D.Change the load balancing policy to Explicit failover order.
Why A: IP hash uses source and destination IP addresses to distribute traffic across uplinks, providing better load distribution. Option B is incorrect because simply adding more uplinks without changing the teaming policy does not redistribute traffic; the originating virtual port still ties the VM to a single uplink. Option C is incorrect because LACP is not supported on standard vSwitches; it requires a distributed switch. Option D is incorrect because explicit failover order does not distribute traffic; it only defines active/standby uplinks.
