SY0-701 Threats, Vulnerabilities, and Mitigations Practice Question
This SY0-701 practice question tests your understanding of threats, vulnerabilities, and mitigations. 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.
Exhibit
Host activity log
11:22:08 Command executed: vssadmin delete shadows /all /quiet
11:22:15 Files in Finance share renamed with extension .enc
11:22:21 Ransom note created: READ_ME_NOW.txt
11:22:28 Multiple user documents no longer open correctly
Based on the exhibit, what type of malware is most likely present?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

A
Ransomware, because the files are being renamed and recovery copies are being deleted.
The combination of shadow copy deletion, mass file renaming, and a ransom note is a strong match for ransomware. The attacker is attempting to prevent recovery while demanding payment or coercing the victim, which is exactly the pattern shown in the exhibit.
B
Adware, because documents are no longer opening correctly.
Why wrong: Adware is usually associated with unwanted advertising, not encryption and destructive recovery actions.
C
Rootkit, because the system is using a command-line utility.
Why wrong: Rootkits focus on hiding presence and persistence, not file encryption and ransom notes.
D
Spyware, because the attacker wants to read user documents.
Why wrong: Spyware is designed to collect information covertly, not to rename files and delete restore points.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ransomware, because the files are being renamed and recovery copies are being deleted.
The exhibit shows files being renamed with a new extension and recovery copies (shadow copies) being deleted via vssadmin.exe. This is a classic ransomware behavior: encrypting user files and removing Volume Shadow Copy backups to prevent recovery without the attacker's key. Ransomware specifically targets document files and system restore points to maximize extortion leverage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why this is correct
The combination of shadow copy deletion, mass file renaming, and a ransom note is a strong match for ransomware. The attacker is attempting to prevent recovery while demanding payment or coercing the victim, which is exactly the pattern shown in the exhibit.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates see 'command-line utility' and think rootkit, but vssadmin deletion is a hallmark of ransomware, not a rootkit's stealth or persistence mechanism.
Detailed technical explanation
How to think about this question
Ransomware often uses vssadmin.exe delete shadows /all /quiet to remove Volume Shadow Copy snapshots, which are Windows' built-in file versioning system. The renaming pattern (e.g., .encrypted appended) indicates symmetric encryption (like AES) with a per-file key, later wrapped by an asymmetric key (RSA) for ransom payment. In real-world attacks, this is combined with disabling Windows Recovery Environment (reagentc) and boot configuration edits to prevent safe mode recovery.

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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
