Full question →mediummultiple choiceObjective-mapped
A technician is troubleshooting a workstation in a small office that loses network connectivity sporadically. The technician notices that the problem occurs every time a nearby heavy-duty laser printer starts a print job. The workstation is connected to the same network switch as the printer but is on a different electrical circuit. The technician has already replaced the Ethernet patch cable and verified the workstation’s network settings are correct. The link light on the workstation’s NIC turns off during the outages. Which of the following should the technician check NEXT?
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
Replace the network interface card (NIC)
A defective NIC might cause intermittent drops, but the problem is specifically correlated with the printer starting, suggesting an external factor like power quality. Replacing the NIC is premature without ruling out power issues.
B
Best answer
Check the power supply unit (PSU) output voltage during a printer startup
The laser printer's high startup current may cause a voltage sag on the electrical system, affecting the workstation’s PSU and causing the NIC to lose power temporarily. Measuring the PSU output during an event can confirm if the voltage drops below acceptable levels.
C
Distractor review
Increase the DHCP lease time on the router
DHCP lease time affects IP address renewal, but the issue is a physical link loss (NIC link light off), which is unrelated to DHCP or IP configuration.
D
Distractor review
Disable power management on the network adapter
Power management settings can cause the NIC to turn off during inactivity, but the user’s problem is correlated with printer activity, not idle periods. Disabling power management would not solve a voltage sag issue.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

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?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Check the power supply unit (PSU) output voltage during a printer startup — Laser printers draw a large amount of current when they start a print job (especially warming up the fuser). This can cause a temporary voltage sag on the electrical circuit. Even though the workstation is on a different circuit, if the printer and workstation share a common power distribution panel or if the building’s wiring is not properly isolated, the voltage dip may affect the workstation’s power supply, causing the NIC to momentarily lose power and drop the link. The technician should verify the power quality by checking the workstation’s PSU output with a multimeter during an outage or consult with building maintenance about relocating equipment to separate circuits. Option A (replace the NIC) would not address a power-related issue. Option B (increase the DHCP lease time) is irrelevant to a physical link loss. Option D (disable power management on the NIC) would not prevent power sags that cause hardware to reset.
