Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A technician is setting up two virtual machines on a Type 1 hypervisor. The VMs need to communicate with each other using private IP addresses, and the traffic must remain within the physical host—it must not traverse the physical network. The hypervisor host is connected to the physical network via a single NIC. Which of the following should the technician configure to meet these requirements?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
An internal virtual switch
Correct. An internal virtual switch allows VMs on the same hypervisor to communicate with each other and with the host OS, but traffic does not go out to the physical network. This meets the requirement of keeping traffic within the host.
B
Distractor review
A virtual network interface card (vNIC) on each VM connected to a bridged adapter
A bridged adapter connects the VMs directly to the physical network, making them appear as separate devices on the network. Traffic between VMs would go through the physical switch, violating the requirement.
C
Distractor review
A NAT network adapter for each VM
NAT allows VMs to share the host's IP address and access external networks, but it still involves routing through the host's network stack and typically sends traffic out the physical NIC. It does not keep all traffic internal.
D
Distractor review
A VLAN ID on the physical switch port that connects to the hypervisor host
Setting a VLAN ID on the physical switch port affects how traffic is tagged on the physical network, but it does not control internal VM communication on the hypervisor. This configuration would not prevent traffic from leaving the host.
Common exam trap
Common exam trap: an active trunk can still block the VLAN you need
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Technical deep dive
How to think about this question
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
KKey Concepts to Remember
- Access ports place end devices into a single VLAN.
- Trunk ports carry multiple VLANs between switches.
- Allowed VLAN lists decide which VLANs can cross a trunk.
- Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
- Use show vlan brief to verify access VLANs.
- Use show interfaces trunk to verify trunk state and allowed VLANs.
- Do not treat every same-VLAN issue as a routing problem.

Question 1
A user reports intermittent network connectivity on a desktop computer. The technician observes that the Ethernet link light on the NIC turns off for a few seconds and then turns back on. The cable passes a wiremap test, the switch port is verified good with another device, and the NIC driver is updated. The issue occurs more frequently when the computer's case fan runs at high speed. Which of the following is the MOST likely cause?
Question 2
A workstation is unable to connect to the internet. The technician runs the 'ipconfig' command and sees the IPv4 address is 169.254.15.200 with a subnet mask of 255.255.0.0. The workstation can ping other devices on the local subnet but cannot ping the default gateway or any external addresses. Which TWO actions should the technician take to resolve this issue? (Select two.)
Question 3
A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?
Question 4
A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?
Question 5
A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?
Question 6
A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?
FAQ
Questions learners often ask
What does this 220-1101 question test?
Access ports place end devices into a single VLAN.
What is the correct answer to this question?
The correct answer is: An internal virtual switch — A virtual switch allows VMs to communicate. An internal virtual switch (sometimes called a private virtual switch in Hyper-V or internal network in VMware) enables communication between VMs on the same host and optionally with the host, but traffic does not go out to the physical network. This is the correct choice for isolating VM traffic to the host. Option B (bridged adapter) connects VMs directly to the physical network, which would cause traffic to leave the host. Option C (NAT) also involves the host forwarding packets, which typically goes to the physical network. Option D is a physical switch configuration, not relevant to virtual networking inside the hypervisor.
