Full question →mediummultiple choiceObjective-mapped
A network technician is setting up a wireless access point (AP) for a small business. The company's router provides DHCP for the 192.168.1.0/24 network. The AP needs to broadcast two SSIDs: one for employees and one for guest users. The guest network must be completely isolated from the employee network and internal resources, while both SSIDs must have internet access. The AP is connected to a managed switch. Which configuration will BEST 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
Distractor review
Place both SSIDs on the same subnet and enable client isolation on the AP
Client isolation prevents wireless clients from communicating with each other, but it does not isolate guest traffic from the wired employee network. Guests could still reach internal resources via the wired network.
B
Best answer
Configure VLANs on the managed switch and set the AP to tag the employee SSID on VLAN 10 and the guest SSID on VLAN 20; configure trunk port on switch to the AP
This properly segments the traffic. The switch will keep frames separate, and the router (if configured with subinterfaces) can route each VLAN to the internet without allowing inter-VLAN routing. This achieves the required isolation.
C
Distractor review
Configure a DHCP reservation on the router for the AP and set the guest SSID to use a static IP in a different subnet
Simply using a different subnet on the guest SSID does not isolate traffic; the switch and router must still be configured to prevent routing between subnets. Without VLANs or ACLs, the router will forward traffic between subnets by default.
D
Distractor review
Disable the guest network's ability to access the default gateway by changing the AP's management settings
If the guest network cannot reach the default gateway, it will not have internet access. The requirement is that both networks have internet access, so this does not meet the goal.
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: Configure VLANs on the managed switch and set the AP to tag the employee SSID on VLAN 10 and the guest SSID on VLAN 20; configure trunk port on switch to the AP — Virtual LANs (VLANs) allow network segmentation at Layer 2. By assigning one VLAN to the employee SSID and a different VLAN to the guest SSID, traffic from the guest network cannot reach the employee network unless a router is configured to route between them (which we avoid for isolation). The managed switch must be configured with these VLANs and the link to the AP must be a trunk to carry both VLANs. The router can then use a single interface (or subinterfaces) to provide internet access to both VLANs while keeping them isolated from each other.
