2V0-622 · Question #142
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
The correct answer is A. VLANs of the physical NICs B. Failover order of the uplinks C. Virtual NIC connectivity to the dvSwitch. When troubleshooting VM-to-VM connectivity across a vSphere Distributed Switch, administrators should examine VLAN configuration, uplink failover order, and vNIC-to-dvSwitch port binding as these directly control whether traffic can pass between hosts.
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

Why each option
When troubleshooting VM-to-VM connectivity across a vSphere Distributed Switch, administrators should examine VLAN configuration, uplink failover order, and vNIC-to-dvSwitch port binding as these directly control whether traffic can pass between hosts.
Security policy settings such as promiscuous mode and MAC address changes affect frame filtering and spoofing prevention but do not typically prevent basic unicast connectivity between two VMs on the same portgroup.
Traffic shaping controls bandwidth throughput limits and burst behavior, and would not block connectivity between virtual machines - it would only throttle or delay traffic.
