Full question →mediummultiple choiceObjective-mapped
A technician is configuring a small office network with a managed switch. A new employee's workstation is connected to port 12 on the switch. The workstation receives an IP address from the DHCP server and can ping the default gateway (192.168.1.1), but it cannot ping the file server at 192.168.1.50. Other workstations on the same subnet can ping the file server. The technician checks the switch configuration and sees that port 12 is assigned to VLAN 10, while all other workstations and the file server are on VLAN 1. Which of the following is the MOST likely reason the workstation cannot reach the file server?
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
Distractor review
The workstation's subnet mask is incorrect
If the subnet mask were incorrect, the workstation would likely not be able to ping the default gateway. Since it can ping the gateway, the IPv4 settings are consistent with the network.
B
Best answer
The switch port is configured as an access port in the wrong VLAN
The switch port is set to VLAN 10, isolating the workstation from VLAN 1 where the file server resides. Without inter-VLAN routing, Layer 2 traffic stays within the VLAN, so the workstation cannot communicate with devices in other VLANs.
C
Distractor review
The workstation's firewall is blocking traffic
While a firewall could block pings, the scenario says the workstation can ping the gateway (which is on a different subnet). If the firewall were blocking all traffic, it would likely block the gateway ping as well. The consistent symptom of reaching only the gateway points to VLAN isolation.
D
Distractor review
The DHCP server assigned an IP from a different scope
The workstation received an IP that allows it to ping the gateway, meaning the DHCP scope is valid for that VLAN. If it had a different scope IP, the subnet would be different and pinging the gateway would likely fail.
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: The switch port is configured as an access port in the wrong VLAN — By default, ports on different VLANs cannot communicate directly; they require a router or Layer 3 switch to forward traffic between VLANs. Since port 12 is in VLAN 10 and the file server is in VLAN 1, the workstation cannot reach the server unless inter-VLAN routing is configured. Even though the workstation can ping the default gateway (which typically resides in VLAN 1), that only proves the workstation has a valid IP and can reach the router, but the router may not be configured to route between VLANs or may have ACLs blocking traffic.
