A technician is troubleshooting a Windows 10 workstation where a user reports that a specific application displays an error: 'The application was unable to start correctly (0xc000007b).' The technician has already reinstalled the application and run SFC and DISM with no issues. Which step should the technician take 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
Reinstall Windows
Reinstalling Windows is a last-resort option and should not be performed before attempting less invasive diagnostic tools to identify the root cause.
B
Best answer
Use Dependency Walker to check for missing DLLs
Dependency Walker (depends.exe) scans an executable and lists all required DLLs, helping to identify missing or corrupted files that cause error 0xc000007b. This is the appropriate next step to pinpoint the missing dependency.
C
Distractor review
Run chkdsk
Chkdsk checks the file system and disk for errors, but this error is related to application dependencies, not disk corruption, so chkdsk is unlikely to resolve it.
D
Distractor review
Update device drivers
Updating drivers addresses hardware-software interaction issues, but this specific error is not driver-related; it is a missing or mismatched runtime library.
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: Use Dependency Walker to check for missing DLLs — Error code 0xc000007b typically indicates a missing or corrupted DLL, often related to Visual C++ redistributables or a bitness mismatch (e.g., trying to run a 64-bit application on a 32-bit system or vice versa). Using Dependency Walker (or Process Monitor) can help identify the specific missing or mismatched DLL. Reinstalling the application and running SFC/DISM were good first steps, but if they didn't resolve the issue, deeper analysis of dependencies is required. Reinstalling Windows is drastic and should be a last resort. Chkdsk checks disk integrity and is unlikely to fix a DLL issue. Updating device drivers would not address application-startup errors of this type.
