Quick Answer

The correct answer is immutable backups stored in a separate repository or offline location because they enforce a write-once-read-many (WORM) policy that prevents deletion or modification even if an attacker has stolen domain admin credentials. In a ransomware incident, credential theft allows attackers to traverse the backup network and delete online backups, but immutability—often implemented via object lock or physical air gaps—ensures backup data remains intact until its retention period expires. On the Security+ SY0-701 exam, this scenario tests your understanding of backup integrity controls versus simple redundancy; a common trap is choosing offsite backups alone, which can still be deleted if credentials are compromised. Remember the memory tip: “Immutable means untouchable—even for an admin.”

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.

After a ransomware incident, management learns the attacker's stolen domain admin credentials were used to delete recent online backups from the same backup network. Which backup strategy would have most reduced the chance of permanent backup loss?

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

Immutable backups stored in a separate repository or offline location.

Immutable backups stored in a separate repository or offline location prevent deletion or modification by an attacker, even with domain admin credentials. This is because immutability enforces a write-once-read-many (WORM) policy, often implemented via object lock (e.g., S3 Object Lock) or a physical air gap, ensuring that backups cannot be altered or deleted before their retention period expires. In this scenario, the attacker's ability to delete online backups from the same network is mitigated because the immutable repository is isolated and resistant to credential-based tampering.

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.

  • Nightly incremental backups stored on the same file server as production data.

    Why it's wrong here

    This keeps backups too close to production and gives an attacker with privileged access a single target to destroy.

  • Immutable backups stored in a separate repository or offline location.

    Why this is correct

    Immutable or offline backups reduce the chance that stolen administrative credentials can alter or delete recovery data.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Hypervisor snapshots only, because they are always safer than backups.

    Why it's wrong here

    Snapshots are useful for short-term recovery but are not a complete backup strategy and can still be vulnerable.

  • Longer retention on the same backup share to keep more versions available.

    Why it's wrong here

    More versions do not help if the attacker can reach and delete the entire backup repository with the same credentials.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may assume longer retention or same-server backups are sufficient, but the key is that immutability and isolation (air gap) are required to prevent an attacker with elevated credentials from deleting backups, which is a core concept tested in SY0-701 Domain 3.0 (Security Operations).

Detailed technical explanation

How to think about this question

Immutable backups rely on technologies like AWS S3 Object Lock with governance or compliance mode, or on-premises solutions using WORM tape or write-protected storage. In a real-world scenario, even with domain admin access, an attacker cannot delete objects locked in compliance mode until the retention period expires, and governance mode can be overridden only by users with specific permissions (e.g., s3:BypassGovernanceRetention). This contrasts with traditional backup shares where the backup service account or domain admin can delete files at will, as seen in attacks like Ryuk or Conti that specifically target backup directories.

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.
