This 200-201 practice question tests your understanding of host-based analysis. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which two Sysmon Event IDs are most commonly associated with code injection techniques?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Event ID 8 (CreateRemoteThread)
Sysmon Event ID 8 (CreateRemoteThread) is directly associated with code injection because it logs when a thread is created in a remote process, a common technique used by malware to inject malicious code into a legitimate process. Event ID 10 (ProcessAccess) is also critical as it records when a process opens a handle to another process, often a precursor to injecting code via APIs like OpenProcess and WriteProcessMemory.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Event ID 3 (Network connect)
Why it's wrong here
Network events are not directly related to injection.
✓
Event ID 8 (CreateRemoteThread)
Why this is correct
CreateRemoteThread is a common method for code injection.

✗
Event ID 1 (Process creation)
Why it's wrong here
Process creation itself is not specific to injection.
✗
Event ID 7 (Image loaded)
Why it's wrong here
Image loads can be part of injection but are not definitive.
✓
Event ID 10 (ProcessAccess)
Why this is correct
ProcessAccess events may indicate a process opening another for injection.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between direct indicators of injection (Event ID 8 and 10) versus indirect artifacts (Event ID 1 or 7), leading candidates to mistakenly choose process creation or image load events as primary injection indicators.
Detailed technical explanation
How to think about this question
Code injection often involves the Windows API call CreateRemoteThread to execute shellcode in a target process's memory space, while ProcessAccess (Event ID 10) captures the preceding OpenProcess call with specific access rights (e.g., PROCESS_CREATE_THREAD, PROCESS_VM_WRITE). In real-world scenarios, adversaries may use process hollowing or reflective DLL injection, where Event ID 8 and 10 provide forensic evidence of the remote thread creation and handle access, respectively, even if the injected code is obfuscated.
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.
TExam Day Tips
→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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 200-201 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.
