Configure and Manage vSphere Networking practice questions

Q: Can I practise just Configure and Manage vSphere Networking questions in a focused session?

Yes — use the session launcher on this page to start a 10-, 20-, 30- or 50-question session drawn entirely from the Configure and Manage vSphere Networking domain.

This domain covers configuring and managing vSphere networking on standard and distributed switches: uplinks, NIC teaming, VLANs, private VLANs, LACP, traffic shaping, and VM connectivity. Questions present design scenarios, exhibits, or misconfigurations and ask you to identify causes or required actions.

Courseiva uses original exam-style practice questions designed for learning and revision. The goal is to understand the concepts, recognise exam patterns, and improve through explanations — not memorise copied exam dumps.

What the exam tests

What to know about Configure and Manage vSphere Networking

You must be able to design and configure vSphere Standard and Distributed Switches, including uplinks, VLANs, NIC teaming, and LACP. The most important thing is ensuring physical switch settings match vSphere settings, especially for LACP and IP hash load balancing.

Creating and configuring vSphere Standard Switches and Distributed Switches with VMkernel and VM port groups

Configuring NIC teaming, failover order, load balancing, and LACP link aggregation groups on distributed switches

Implementing VLAN tagging, private VLANs, traffic shaping, and NetFlow on distributed switch port groups

Verifying network connectivity using vmkping, esxcli network commands, and physical switch LACP settings

Watch out for

Common Configure and Manage vSphere Networking exam traps

▸Assuming LACP will come up without matching LACP mode and channel-group configuration on the physical switch.
▸Forgetting that VMkernel adapters require a port group with the correct VLAN ID and services enabled.
▸Mixing up load balancing policies: originating virtual port ID versus IP hash, which requires EtherChannel on the physical switch.

Question 1mediummultiple choice

Open the full VLAN trunking answer →

A vSphere administrator is troubleshooting connectivity issues for a virtual machine on a standard switch. The VM is configured with VLAN 100, but cannot ping the default gateway. The VMkernel port on the host is on VLAN 200. The physical switch port connected to the host is configured as a trunk port allowing VLANs 100 and 200. Which action should the administrator take to resolve the issue?

Trap 1: Enable promiscuous mode on the VM port group.

Promiscuous mode lets a vNIC receive frames not addressed to it; it does not correct a VLAN tagging mismatch between the VM's port group and the uplink. It is tempting because it is often reached for when traffic appears blocked; it would be correct for monitoring or nested-virtualisation capture scenarios.

Trap 2: Change the physical switch port to access mode on VLAN 100.

Access mode carries only one VLAN, so the trunk would stop passing VLAN 200 for the VMkernel port, breaking host management traffic. It is tempting because access ports simplify VLAN assignment; it would be correct if the host needed only a single VLAN on that uplink.

Trap 3: Set the VM port group VLAN to 4095.

VLAN 4095 on a port group trunks every VLAN, so the guest's own VLAN 100 tagging would be passed untagged or double-tagged incorrectly, and the gateway remains unreachable. It is tempting because 4095 resembles a trunk-all setting; it would be correct for a port group carrying multiple VLANs to a VLAN-aware guest.

A
Enable promiscuous mode on the VM port group.
Why it fails: Promiscuous mode lets a vNIC receive frames not addressed to it; it does not correct a VLAN tagging mismatch between the VM's port group and the uplink. It is tempting because it is often reached for when traffic appears blocked; it would be correct for monitoring or nested-virtualisation capture scenarios.
B
Change the physical switch port to access mode on VLAN 100.
Why it fails: Access mode carries only one VLAN, so the trunk would stop passing VLAN 200 for the VMkernel port, breaking host management traffic. It is tempting because access ports simplify VLAN assignment; it would be correct if the host needed only a single VLAN on that uplink.
C
Ensure the VM port group is set to VLAN 100.
The VM's port group must carry VLAN 100 to match the VM's tagging; if the port group is set to VLAN 200 or none, traffic is tagged or untagged incorrectly and cannot reach the gateway. The physical trunk already permits VLAN 100, so only the port group setting needs correcting.
D
Set the VM port group VLAN to 4095.
Why it fails: VLAN 4095 on a port group trunks every VLAN, so the guest's own VLAN 100 tagging would be passed untagged or double-tagged incorrectly, and the gateway remains unreachable. It is tempting because 4095 resembles a trunk-all setting; it would be correct for a port group carrying multiple VLANs to a VLAN-aware guest.

Configure and Manage vSphere Networking questions

A vSphere administrator is deploying a vSphere Distributed Switch (vDS) version 7.0. The environment has ESXi hosts with hardware version 7.0. The administrator needs to ensure that the vDS supports Network I/O Control version 3 (NIOCv3). What must be true for NIOCv3 to function correctly?

An administrator is troubleshooting SSH connectivity to an ESXi host from a management workstation at 10.10.10.2. The SSH session is established, but the administrator cannot ping the host's IP 10.10.10.1. Based on the exhibit, what is the most likely cause?

Exhibit

Which TWO conditions must be met to successfully enable vSphere Network I/O Control (NIOC) on a vSphere Distributed Switch? (Choose two.)

An administrator is configuring a vSphere distributed switch. Which TWO are valid uplink teaming policies? (Choose two.)

Match each vSphere edition/license tier to its key feature.

An administrator configures a distributed switch with a single uplink on each host and a port group with VLAN 10. After connecting a VM to the port group, the VM cannot communicate with other VMs on the same VLAN but on different hosts. What is a likely cause?

An ESXi host has two physical uplinks (vmnic0, vmnic1) connected to a distributed switch. The administrator wants to use LACP to aggregate these uplinks to a physical switch stack. Which prerequisite must be met for LACP to work with a distributed switch?

An administrator configures a Private VLAN on a distributed switch with primary VLAN 100 and secondary VLANs 101 (isolated) and 102 (community). A VM on isolated secondary VLAN 101 needs to communicate with a VM on community secondary VLAN 102. What additional configuration is required?

Which two conditions must be met for a VMkernel adapter to be used for vMotion on a distributed switch? (Choose two.)

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?

Exhibit

An administrator needs to ensure that virtual machines can be migrated between ESXi hosts using vMotion. The virtual machines are connected to a standard vSwitch port group named 'Production'. What must be consistent across all hosts?

An administrator has enabled jumbo frames (MTU 9000) on a vSphere Distributed Switch. Virtual machines on different hosts cannot communicate, but VMs on the same host can. The physical switches support jumbo frames. What is the most likely cause?

An administrator is configuring a vSphere Standard Switch. Which two settings are essential for basic network connectivity of virtual machines?

An administrator is troubleshooting network connectivity for a virtual machine connected to a vSphere Distributed Switch. Which three components must be properly configured for the VM to communicate with the external network?
