This CCSP practice question tests your understanding of cloud data security. 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.
Network Topology
The exhibit shows the versioning configuration for an S3 bucket. What effect does enabling MFADelete have on data protection?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It requires MFA to permanently delete an object version
Enabling MFADelete on an S3 bucket requires multi-factor authentication to permanently delete an object version or to suspend versioning on the bucket. This adds a critical layer of protection against accidental or malicious deletion of object versions, ensuring that even with administrative credentials, a second factor is needed to complete the destructive operation. It does not affect encryption, overwrite prevention, or all operations—only permanent deletion and versioning suspension.
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.
✗
It automatically encrypts all new object versions
Why it's wrong here
Encryption is separate from versioning and MFADelete.
✓
It requires MFA to permanently delete an object version
Why this is correct
MFADelete adds MFA protection for delete operations.
Related concept
Read the scenario before looking for a memorised answer.
✗
It prevents any version of an object from being overwritten
Why it's wrong here
Overwriting is still allowed; versioning keeps previous versions.
✗
It requires MFA for all operations on the bucket
Why it's wrong here
MFADelete only applies to version deletion and suspending versioning.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the misconception that MFADelete applies to all bucket operations, when in fact it only applies to permanent deletion of object versions and suspension of versioning, not to reads, writes, or other management actions.
Detailed technical explanation
How to think about this question
MFADelete is configured via the bucket's versioning subresource using the `x-amz-mfa` header in PUT requests to the versioning configuration. Under the hood, AWS generates a serial number and a six-digit one-time password from a hardware or virtual MFA device, which must be included in the request. In a real-world scenario, an organization might enable MFADelete on a bucket containing critical audit logs to prevent an attacker with compromised root credentials from silently deleting evidence, as the attacker would also need physical access to the MFA device.

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.
