Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A user reports that their workstation experiences intermittent network disconnections, often during peak office hours. The technician tests the Cat6 Ethernet cable with a continuity tester; the cable passes all four pairs. The network adapter is set to auto-negotiate and reports a link speed of 1 Gbps when connected. However, after observing the switch port, the technician notices a high number of CRC errors and late collisions. The cable runs through a dropped ceiling and is routed near fluorescent light ballasts. Which of the following should the technician do FIRST to resolve the issue?
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
Best answer
Replace the network cable with a shielded (STP) cable
Shielded twisted pair cable is designed to reduce electromagnetic interference from sources like fluorescent lights. This is the most direct fix for CRC errors caused by EMI.
B
Distractor review
Configure jumbo frames on the workstation and switch
Jumbo frames can improve throughput by reducing overhead, but they do not address the underlying CRC errors and late collisions caused by electrical interference.
C
Distractor review
Replace the network interface card (NIC) in the workstation
While a faulty NIC could cause errors, the cable proximity to fluorescent lights and the nature of CRC errors (corrupted packets) strongly point to external interference rather than a hardware failure.
D
Distractor review
Replace the switch with one that supports auto-MDI/X
Auto-MDI/X automatically adjusts for cable type, but the link is already established at 1 Gbps. This feature does not mitigate EMI or reduce CRC errors.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

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?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Replace the network cable with a shielded (STP) cable — High CRC errors and late collisions often indicate electromagnetic interference (EMI) or signal degradation. Running unshielded twisted pair (UTP) cable near fluorescent lights is a classic source of EMI. Even though the cable passes a continuity test, interference can corrupt packets at higher frequencies. Replacing the UTP cable with shielded twisted pair (STP) cable will reduce susceptibility to EMI. The other options are less likely: jumbo frames help with throughput but not interference, replacing the NIC without addressing the root cause is premature, and a better switch may not help if the cable is picking up noise.
