A company replaces an unmanaged network switch with a new managed switch in a small office. After reconnecting all devices, some workstations can access the internet, but others cannot. The workstations that cannot access the internet are all connected to ports 1-8 of the new switch, while workstations on ports 9-16 work normally. The router is connected to port 24. The technician checks the switch configuration and finds that all ports are in the default VLAN 1, but ports 1-8 have been accidentally reassigned to VLAN 2. Which of the following is the MOST likely reason the workstations on ports 1-8 cannot access the internet?

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 switch needs to be power cycled to apply the VLAN configuration changes.

Power cycling would not change the VLAN assignment; the configuration is stored in non-volatile memory and would persist. The issue is the VLAN membership, not a need for a reboot.

B

Best answer

The workstations on ports 1-8 are on a different VLAN than the router, preventing them from reaching the default gateway.

The router is on VLAN 1, but ports 1-8 are on VLAN 2. Without a router configured for inter-VLAN routing, devices on VLAN 2 cannot communicate with the router, so they lose internet access.

C

Distractor review

The workstations on ports 1-8 have incorrect subnet masks configured.

Even if the subnet mask were incorrect, the workstations would still attempt to send traffic to the default gateway MAC address if they are on the same VLAN. Since they are on a different VLAN, they cannot even reach the gateway at Layer 2.

D

Distractor review

The switch ports are not configured as trunk ports for the router connection.

Trunk ports are used to carry multiple VLANs between switches. The router is a single endpoint and should be in an access port in the appropriate VLAN. Trunking is not the issue here.

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 workstations on ports 1-8 are on a different VLAN than the router, preventing them from reaching the default gateway. — VLANs create separate broadcast domains. When ports 1-8 are assigned to VLAN 2 and the router is on VLAN 1, workstations on VLAN 2 cannot communicate with the router (their default gateway) unless a Layer 3 device forwards traffic between VLANs. In this basic setup, no inter-VLAN routing is configured, so internet access fails for the isolated workstations. Power cycling the switch would not change the VLAN assignment. Subnet mask configuration on the workstations is irrelevant because they cannot reach the router at all. Trunk mode is used for inter-switch connections, not for connecting endpoints.

What should I do if I get this 220-1101 question wrong?
