Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A network administrator configures a new managed switch with 24 ports. All ports are in the same VLAN (VLAN 1) by default. The administrator then changes ports 1-12 to VLAN 10 and ports 13-24 to VLAN 20. Computers connected to ports in different VLANs are assigned IP addresses from the same DHCP server. Which of the following is a direct consequence of this configuration?
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
Computers in different VLANs can communicate directly at Layer 2
VLANs isolate traffic at Layer 2. A switch does not forward frames between different VLANs unless it is a Layer 3 switch with inter-VLAN routing configured.
B
Best answer
Computers in different VLANs cannot communicate unless a router is configured
To communicate between VLANs, a router (or Layer 3 switch) must be configured to route traffic between the VLANs. Without routing, they are separate broadcast domains.
C
Distractor review
The switch will forward traffic between VLANs using internal routing
A standard Layer 2 switch does not perform routing between VLANs. Internal routing requires a Layer 3 switch with routing capabilities enabled.
D
Distractor review
DHCP requests from VLAN 20 will be dropped by the switch
DHCP requests are broadcast frames. Without a DHCP relay, broadcasts are confined to the local VLAN. However, if the DHCP server is in a different VLAN, requests will not reach it unless a relay agent is configured, but the statement 'dropped by the switch' is inaccurate; they simply do not cross VLAN boundaries.
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: Computers in different VLANs cannot communicate unless a router is configured — VLANs segment the network at Layer 2, isolating traffic between different VLANs. Without a router or Layer 3 switch, devices in different VLANs cannot communicate even if they share the same physical switch.
