- A
Implement a backup solution with immutable snapshots and offsite storage.
Immutable backups protect against ransomware altering or deleting backups.
- B
Enable vMotion encryption for all migrations.
Why wrong: vMotion encryption protects in-transit data but does not prevent ransomware attacks.
- C
Use VM snapshots as primary backup method.
Why wrong: Snapshots are not backups; they can be deleted and do not provide immutable protection.
- D
Enable vSAN encryption to protect data at rest.
Encryption protects data even if storage is accessed.
- E
Configure the distributed firewall to allow all outbound traffic by default.
Why wrong: Best practice is to deny by default and allow only necessary traffic.
Question 171 of 521
vSphere Ransomware Protection: Immutable Backups and Encryption
This VCP-DCV practice question tests your understanding of vsphere security. 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.
Which TWO of the following are best practices for securing a vSphere environment against ransomware attacks?

Noticing these words before you look at the options changes how you read each choice.

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
✓
Implement a backup solution with immutable snapshots and offsite storage.
The correct answers are A and D. Implement a backup solution with immutable snapshots and offsite storage (A) ensures backups cannot be deleted or encrypted by ransomware, enabling recovery. Enabling vSAN encryption (D) protects data at rest, preventing unauthorized access if storage is compromised. Option B is wrong because vMotion encryption protects data in transit during migration, not against ransomware. Option C is wrong because VM snapshots are not backups; they can be deleted by ransomware and do not provide long-term recovery. Option E is wrong because allowing all outbound traffic by default violates the principle of least privilege and increases attack surface.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Configure the distributed firewall to allow all outbound traffic by default.
Why it's wrong here
Best practice is to deny by default and allow only necessary traffic.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related VCP-DCV questions on access control and AAA configuration.
