2V0-621 Question #142: Real Exam Question with Answer & Explanation
The correct answer is A: VLANs of the physical NICs. Troubleshooting inter-VM connectivity on a vSphere Distributed Switch requires checking that VLAN tags are consistent end-to-end, that uplink failover order is correct, and that each VM's vNIC is actually connected to the dvSwitch.
Question
An administrator is experiencing network connectivity issues between virtual machines. The virtual machines and hosts are configured as follows: - VM1 is running on Host1 - VM2 is running on Host2 - Both Host1 and Host2 are attached to the vSphere Distributed Switch dvSwitch1 - Both Host1 and Host2 are using vmnic0 and vmnic1 on dvSwitch1 - Both virtual machines are using the default portgroup for network traffic What are three settings the administrator should investigate while troubleshooting the connectivity issue? (Choose three.)
Options
- AVLANs of the physical NICs
- BFailover order of the uplinks
- CVirtual NIC connectivity to the dvSwitch
- DSecurity policy of the portgroup
- ETraffic shaping on the portgroup
Explanation

Common mistakes.
- D. Security policy settings such as promiscuous mode or MAC address changes affect frame visibility and spoofing protection but do not typically block basic unicast connectivity between two VMs on the same portgroup.
- E. Traffic shaping controls bandwidth allocation and burst limits; it does not block or drop connectivity and would not explain a complete network connectivity failure.
