- A
All Paths Down: All storage paths to a LUN are unavailable.
All Paths Down indicates complete loss of connectivity to a storage LUN.
- B
Device or Resource Busy: The device or resource is currently in use.
Device or Resource Busy occurs when an operation cannot proceed because the resource is locked or active.
- C
Not Enough Resources: The host does not have enough CPU or memory resources to complete the operation.
Not Enough Resources indicates insufficient compute capacity for a request.
- D
Permission Denied: The user does not have the required permissions to perform the action.
Permission Denied means the user lacks appropriate rights or privileges.
- E
All Paths Down: The device or resource is currently in use.
Why wrong: Incorrect — this definition belongs to 'Device or Resource Busy', not 'All Paths Down'.
- F
Permission Denied: All storage paths to a LUN are unavailable.
Why wrong: Incorrect — this definition belongs to 'All Paths Down', not 'Permission Denied'.
VCP-DCV vSphere Architecture, Products and Solutions Practice Question
This VCP-DCV practice question tests your understanding of vsphere architecture, products and solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Match each vSphere error/message to its meaning.
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
All Paths Down: All storage paths to a LUN are unavailable.
Correct matches: All Paths Down refers to storage path failure; Device or Resource Busy indicates resource contention; Not Enough Resources means insufficient CPU/memory; Permission Denied relates to authorization. Common confusions involve swapping definitions between All Paths Down and Device or Resource Busy, or between All Paths Down and Permission Denied.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

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.
