Full question →hardmultiple choiceObjective-mapped
A technician configures a server with a static IP address of 192.168.1.100, subnet mask 255.255.0.0, and default gateway 192.168.1.1. The server can access the internet and devices on the 192.168.1.0/24 network. However, it cannot reach a network printer at 192.168.2.50. The printer is on the same physical LAN but in a different subnet (192.168.2.0/24). The router's interface for the 192.168.2.0 network is 192.168.1.2, and routing is properly configured. Other devices on the 192.168.1.0/24 network (with correct subnet mask 255.255.255.0) can reach the printer successfully. Which of the following is the MOST likely cause of the server's inability to reach the printer?
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 server's default gateway should be set to 192.168.1.2 instead of 192.168.1.1
The default gateway is already 192.168.1.1, which is the router's IP on the same subnet (192.168.1.0/24). The router's other interface 192.168.1.2 is for a different subnet. Changing the gateway to 192.168.1.2 would not fix the issue because the core problem is the subnet mask causing the server to not use the gateway at all.
B
Best answer
B. The server's subnet mask is too broad, causing it to try to reach the printer directly rather than through the gateway
With a subnet mask of 255.255.0.0, the server believes the entire 192.168.0.0/16 range is local. It will attempt to ARP for 192.168.2.50 instead of forwarding to the gateway. Changing the mask to 255.255.255.0 resolves the issue.
C
Distractor review
C. The router is blocking traffic from the server's IP address to the 192.168.2.0 network
The router is not blocking traffic; other devices reach the printer successfully. The issue is that the server never sends traffic to the router because it incorrectly considers the destination local.
D
Distractor review
D. The printer's default gateway is misconfigured
The printer's default gateway is irrelevant for this scenario because the problem is at the server side. The server cannot even initiate the communication due to its own incorrect subnet mask.
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

CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: B. The server's subnet mask is too broad, causing it to try to reach the printer directly rather than through the gateway — The server's subnet mask is 255.255.0.0, which gives it a network address of 192.168.0.0 and a broadcast of 192.168.255.255. Therefore, when the server tries to reach 192.168.2.50, its operating system determines that the destination is on the same local network (since 192.168.2.50 falls within 192.168.0.0/16). Instead of sending the traffic to the default gateway (192.168.1.1), the server attempts to ARP for 192.168.2.50 directly on the local link. Because the printer is on a different subnet, the ARP request never receives a reply, and the communication fails. The fix is to change the server's subnet mask to 255.255.255.0 so it properly routes traffic to 192.168.2.0/24 via the gateway.
