- A
Increase the backup frequency to every hour while keeping the same NAS design.
Why wrong: More frequent backups help recovery points, but they do not protect the backups from domain compromise.
- B
Store all backups on the same network segment for faster restore access.
Why wrong: Keeping backups close to production increases the chance that ransomware reaches them too.
- C
Maintain an offline or immutable backup copy in a separate administrative boundary.
Offline or immutable backups resist tampering and remain available even if the production domain is compromised.
- D
Use only snapshots on the production storage array because they are instant to restore.
Why wrong: Snapshots can still be deleted or encrypted if the attacker gains storage administration access.
SY0-701 Security Operations Practice Question
This SY0-701 practice question tests your understanding of security operations. 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 branch office stores nightly backups on a NAS that is joined to the same Active Directory domain as the production servers. After a ransomware incident, management wants a backup design that is much harder for attackers to encrypt or delete. Which approach is the best improvement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Maintain an offline or immutable backup copy in a separate administrative boundary.
Option C is correct because maintaining an offline or immutable backup copy in a separate administrative boundary ensures that attackers cannot encrypt or delete the backups, even if they compromise the Active Directory domain. An offline backup (e.g., tape or disconnected disk) is physically isolated, while immutable backups (e.g., using S3 Object Lock or a NAS with WORM capabilities) prevent modification or deletion for a defined retention period. This design breaks the attacker's ability to propagate ransomware to the backup repository, addressing the core requirement of making backups much harder to encrypt or delete.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume increasing backup frequency or keeping backups on the same network segment improves recovery speed, but they overlook the fundamental need for isolation and immutability to protect against ransomware encryption and deletion.
Detailed technical explanation
How to think about this question
Immutable backups often rely on technologies like S3 Object Lock, which enforces a WORM (Write Once, Read Many) model at the object level, or NAS features such as NetApp SnapLock that use a retention period to prevent deletion even by administrators. Offline backups, such as tape or disconnected disk, require physical access or manual reconnection, creating an air gap that ransomware cannot cross. In real-world scenarios, attackers frequently target backup repositories by exploiting domain trust relationships, so separating administrative boundaries (e.g., using a separate domain or cloud tenant) is critical.
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 SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
