This VA-003 practice question tests your understanding of assess vault tokens. 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.
A Vault cluster has a token with the following policy: path "secret/data/dev/*" { capabilities = ["read", "list"] }. The token is used to read a secret at "secret/data/dev/password". The read succeeds. Later, the token tries to read "secret/data/prod/password". What happens?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Fails because the token needs an explicit policy for "secret/data/prod/".
The token does not have permissions on the "secret/data/prod/" path, so the read fails with a permission denied error.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Fails with a system error.
Why it's wrong here
The failure is a permission denied, not a system error.
✗
Succeeds because token has read capability on all secrets.
Why it's wrong here
Policies are path-specific; the token only has access to "secret/data/dev/".
✗
Succeeds because the token can list and read any path.
Why it's wrong here
Listing and reading are limited to the paths in the policy.
✓
Fails because the token needs an explicit policy for "secret/data/prod/".
Why this is correct
The token's policy only covers "dev/*", not "prod/*".
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related VA-003 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Fails because the token needs an explicit policy for "secret/data/prod/". — The token does not have permissions on the "secret/data/prod/" path, so the read fails with a permission denied error.
