Full question →mediummultiple choiceObjective-mapped
A technician is setting up a small network for a home office. The ISP modem provides a public IP address via DHCP. The technician connects a wireless router's WAN port to the modem and configures the router to use DHCP on the WAN interface. The router's LAN network is 192.168.1.0/24. A user connects a laptop via Ethernet to one of the router's LAN ports and can access the internet. However, the user's network printer, which has a static IP address, was previously connected directly to the modem and now cannot be reached from the laptop. The printer is powered on and its Ethernet link light is on. Which of the following is the most likely cause?
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
A. The printer's firewall is blocking ICMP
Most network printers do not have firewalls that block ICMP out of the box, and this would not explain the complete lack of connectivity.
B
Best answer
B. The printer's static IP address is on a different subnet from the router's LAN
The printer likely retains an IP address from its previous connection to the modem (e.g., a public IP or a different private range), making it unreachable from the laptop on the 192.168.1.0/24 network.
C
Distractor review
C. The printer needs to be connected to the WAN port of the router
The printer is a local network device; it should be connected to a LAN port or switch. The WAN port is for connecting to the modem.
D
Distractor review
D. The router's DHCP server is conflicting with the printer's static IP
A DHCP conflict would cause issues for the client that receives the conflicting IP, but it would not prevent communication if the printer is on the correct subnet. The more fundamental issue is subnet mismatch.
Common exam trap
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Technical deep dive
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.

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?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: B. The printer's static IP address is on a different subnet from the router's LAN — The printer was originally connected directly to the ISP modem, so it likely received or was statically assigned an IP address from the ISP's public subnet or a different private subnet. Now that it is connected to the router's LAN switch ports, it must have an IP address on the same subnet as the router's LAN (192.168.1.0/24) to be reachable from the laptop. If the printer still has an IP address from the old network, it will be on a different subnet and the laptop will not be able to reach it. A DHCP conflict (option D) would only occur if the router's DHCP server assigned an IP that matches the printer's static IP, but that would not explain why the printer is unreachable if the static IP is in the correct subnet; in fact, it could cause a conflict but that is less likely given the printer was previously on a different network. Option A (firewall) is unlikely on a typical network printer. Option C is incorrect because the printer should be connected to a LAN port, not the WAN port.
