A technician is troubleshooting a user's Windows 10 workstation where a legacy business application fails to launch. The application was working yesterday, but after a recent Windows Update was installed automatically overnight, the application now displays an error indicating it is not compatible. The technician has already rolled back the update, but the application still will not launch. Which of the following should the technician try NEXT 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.
Distractor review
Run the System File Checker (SFC) to repair any corrupted system files.
SFC is used to repair system file corruption, but the error suggests compatibility, not corruption. It is not the most direct next step.
Best answer
Use the Program Compatibility Troubleshooter to set the application to run in compatibility mode.
The Compatibility Troubleshooter is designed to diagnose and resolve issues where programs that worked on older Windows versions fail after updates. It can apply the correct compatibility settings.
Distractor review
Uninstall and reinstall the legacy application to restore its original configuration.
Reinstalling is more time-consuming and may not fix the compatibility issue if the update changed the system environment. It should be a later step.
Distractor review
Check for updated drivers for the application from the manufacturer's website.
The application is a software program, not a driver. Driver updates are not relevant here.
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: Use the Program Compatibility Troubleshooter to set the application to run in compatibility mode. — After rolling back an update, if the application still does not work, the next step is to use the Program Compatibility Troubleshooter. This tool can automatically detect and apply compatibility settings (e.g., running the app as an administrator or in compatibility mode for an older Windows version). Reinstalling the application might work but is more drastic and may not address the compatibility issue. Checking for newer drivers is unrelated because the issue is with the application, not drivers. Running SFC is for system file corruption, but the problem is more likely compatibility-related.
