VA-003 Compare authentication methods Practice Question
This VA-003 practice question tests your understanding of compare authentication methods. 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.
Exhibit
Refer to the exhibit.
```
$ vault auth list
Path Type Accessor Description
userpass/ userpass auth_userpass_xxxx Userpass auth
ldap/ ldap auth_ldap_yyyy LDAP auth
approle/ approle auth_approle_zzzz AppRole auth
token/ token auth_token_wwww Token auth
```
A Vault administrator runs `vault auth list` and sees the output above. The administrator wants to disable the default token authentication method to improve security. Which command should they run?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
vault auth disable token/
The `vault auth list` output shows that the default token authentication method is enabled at the `token/` path. To disable it, the administrator must run `vault auth disable token/`, which removes the token auth method entirely. This improves security by preventing unauthenticated users from using the default token login endpoint, forcing the use of other configured auth methods like LDAP or AppRole.
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.
✗
vault auth disable userpass/
Why it's wrong here
This disables userpass, not token.
✓
vault auth disable token/
Why this is correct
This disables the token auth method at path token/.
Clue confirmation
The clue word "which command" in the question point toward this answer.

✗
vault auth disable ldap/
Why it's wrong here
This disables LDAP, not token.
✗
vault auth disable approle/
Why it's wrong here
This disables AppRole, not token.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume the default token method cannot be disabled or confuse it with other auth methods like userpass or LDAP, leading them to select an option that disables a different auth method instead of the correct `token/` path.
Detailed technical explanation
How to think about this question
The token auth method is the built-in default in Vault and is always mounted at `token/` unless explicitly disabled. Disabling it removes the ability to authenticate via `vault login` without a token, which is critical in production environments where you want to enforce stronger auth methods like LDAP or OIDC. Under the hood, `vault auth disable` unmounts the auth method's path and revokes all associated tokens, so administrators must ensure alternative auth methods are configured and accessible before disabling the default token method.

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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
