220-1102 Practice Question: A technician is installing a business application…
This 220-1102 practice question tests your understanding of a technician is installing a business application…. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is installing a business application on a Windows 10 workstation. The installation fails with the error 'Fatal error during installation (Error 1603)'. The technician confirms there is sufficient disk space and the user has administrative privileges. What is the most likely cause of this error?
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
The installer file is corrupt
A corrupt installer would likely produce a different error, such as a CRC mismatch or 'file not found'.
B
Distractor review
Antivirus software is blocking the installation
Antivirus interference often results in a warning or silent failure, not the specific Error 1603.
C
Best answer
Required runtime prerequisites are missing
Many applications depend on shared libraries like .NET or Visual C++; Error 1603 is a common result when those are absent.
D
Distractor review
The user account is not a local administrator
The scenario states the user has administrative privileges, so this is not the cause.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.
- ✗
The installer file is corrupt
A corrupt installer would likely produce a different error, such as a CRC mismatch or 'file not found'.
- ✗
Antivirus software is blocking the installation
Antivirus interference often results in a warning or silent failure, not the specific Error 1603.
- ✗
The user account is not a local administrator
The scenario states the user has administrative privileges, so this is not the cause.
Common exam trap
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Technical deep dive
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

FAQ
Questions learners often ask
What does this 220-1102 question test?
Authentication checks who the user is.
What is the correct answer to this question?
The correct answer is: Required runtime prerequisites are missing — Error 1603 often indicates that required prerequisites, such as specific versions of the .NET Framework, Visual C++ Redistributable, or other runtime components, are missing. The technician should review the application's system requirements and install the necessary components. Insufficient permissions are ruled out by the scenario, and antivirus blocking typically presents different errors.
What should I do if I get this 220-1102 question wrong?
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related 220-1102 questions on access control and AAA configuration.
