Full question →hardmultiple choiceObjective-mapped
A user reports that a 64-bit business application on Windows 10 Pro crashes immediately after launch with error code 0xc000007b. The technician has already reinstalled the application, verified that all Windows updates are current, and ran System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM) with no issues found. All required Visual C++ Redistributable packages are present. Which of the following should the technician do NEXT to identify the root cause?
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
Roll back the most recent Windows update
While a recent update could cause DLL mismatches, the technician has already verified system file integrity using SFC and DISM, and the issue is not likely resolved by rolling back. It is not the best next step for identifying the specific dependency problem.
B
Best answer
Use Dependency Walker to analyze the application's DLL dependencies
Dependency Walker can show which DLL files the application expects and whether any are missing or of the wrong bitness (32-bit vs 64-bit). This directly targets the common cause of error 0xc000007b.
C
Distractor review
Temporarily disable the antivirus software and relaunch the application
Disabling antivirus might help if the software is incorrectly flagging the app, but it does not diagnose the underlying dependency issue. It is a troubleshooting step that could be tried later, but not the next logical step after more direct approaches have been exhausted.
D
Distractor review
Perform a clean installation of Windows 10
Reinstalling Windows 10 is a last-resort measure. It would likely resolve the issue but is time-consuming and unnecessary when a focused tool like Dependency Walker can identify the specific broken dependency.
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 analyze the application's DLL dependencies — Error code 0xc000007b typically indicates a 32-bit/64-bit DLL mismatch or a missing dependency. Since the technician has already addressed common causes (reinstall, updates, system file integrity, and Visual C++ redistributables), the next logical step is to use a tool like Dependency Walker to analyze the application's DLL dependencies. This tool can reveal which specific DLL is missing or incorrect (e.g., a 32-bit application trying to load a 64-bit DLL or vice versa). Option B is the correct next step. Rolling back the last Windows update (option A) is unlikely to help if the issue persists after reinstalling the application and running SFC/DISM. Disabling antivirus (option C) might be a temporary test but is not a diagnostic step to identify the root cause. Reinstalling Windows 10 (option D) is too drastic and should be reserved as a last resort after all other troubleshooting has failed.
