Quick Answer
The answer is `regsvr32 /s C:\App\core.dll`, which uses the Regsvr32 command-line tool to silently register a DLL file. This command is correct because it both verifies that the core DLL is present in the specified path and properly registers it in the Windows Registry, ensuring the application can locate and load its required components at launch. On the CompTIA A+ Core 2 220-1202 exam, this question tests your ability to troubleshoot application failures by checking DLL registration, a common real-world scenario after software deployment. A frequent trap is confusing `regsvr32` with tools like `sfc /scannow` (which repairs system files) or `ipconfig` (which handles networking), but remember that DLL registration is specifically about making dynamic link libraries known to the operating system. A handy memory tip: think of "Reg" for Registry and "svr" for server—Regsvr32 tells Windows where to find the DLL server.
This 220-1202 practice question tests your understanding of windows command-line tools. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
After deploying a new application to 50 workstations, several users report that the application crashes on launch. You need to quickly check if the application's core DLL files are present and correctly registered on a remote computer. Which command should you use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
regsvr32 /s C:\App\core.dll
Registers the specified DLL silently, and if successful, confirms the DLL is present and registered.
ipconfig /flushdns
Why wrong: Flushes the DNS cache, unrelated to DLL registration.
chkdsk C:
Why wrong: Checks the disk for errors, not DLL registration.
tasklist /S remotePC
Why wrong: Lists processes on a remote computer, but does not check DLL registration.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
regsvr32 /s C:\App\core.dll
The correct answer is `regsvr32` which is used to register or unregister DLL files. This command verifies that the necessary DLLs are properly registered, which is essential for application functionality. Incorrect answers involve network configuration, file system repair, or process listing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
regsvr32 /s C:\App\core.dll
Why this is correct
Registers the specified DLL silently, and if successful, confirms the DLL is present and registered.
Clue confirmation
The clue word "which command" in the question point toward this answer.

ipconfig /flushdns
Why it's wrong here
Flushes the DNS cache, unrelated to DLL registration.
chkdsk C:
Why it's wrong here
Checks the disk for errors, not DLL registration.
tasklist /S remotePC
Why it's wrong here
Lists processes on a remote computer, but does not check DLL registration.
Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
