This VA-003 practice question tests your understanding of create vault policies. 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.
A company has deployed Vault with an LDAP auth method and has created entity aliases for all users. The company uses KV v2 secrets engine mounted at 'secret/'. Each team's secrets are stored under a path like 'secret/data/team_<team_name>/'. They have multiple teams (engineering, marketing, sales). Currently, an administrator manually creates a separate policy for each team, e.g., path "secret/data/team_engineering/*" { capabilities = ["read", "list"] }. This is becoming cumbersome as new teams are added. The administrator wants to create a single policy that dynamically grants read access to the secrets path corresponding to the user's team, which is stored in the entity's metadata as 'team'. The LDAP auth method is configured to sync group memberships and map to entity aliases, and the entity metadata is correctly populated. Which approach should the administrator take?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a policy using a templated path: path "secret/data/{{identity.entity.metadata.team}}/*" { capabilities = ["read", "list"] }.
Option B is correct because Vault's policy templating allows using {{identity.entity.metadata.team}} to dynamically insert the team name from the entity's metadata into the path. This creates a single policy that works for all teams without manual updates. Option A gives too broad access. Option C is not a valid policy mechanism. Option D is insecure and not scalable.
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.
✗
Create a policy using a wildcard alias for each team in the entity alias.
Why it's wrong here
Wildcard aliases are not used in policies; policies use path patterns.
✗
Create a policy that uses the 'default' policy to allow all reads and then restrict with ACL tokens.
Why it's wrong here
The default policy grants limited capabilities; this approach is insecure and not scalable.
✓
Create a policy using a templated path: path "secret/data/{{identity.entity.metadata.team}}/*" { capabilities = ["read", "list"] }.
Why this is correct
This uses entity metadata to dynamically match the correct team path.
Related concept
Static NAT maps one inside address to one outside address.
✗
Create a policy with path "secret/data/*" { capabilities = ["read", "list"] } and assign it to all users.
Why it's wrong here
This grants access to all team secrets, violating least privilege.
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: Create a policy using a templated path: path "secret/data/{{identity.entity.metadata.team}}/*" { capabilities = ["read", "list"] }. — Option B is correct because Vault's policy templating allows using {{identity.entity.metadata.team}} to dynamically insert the team name from the entity's metadata into the path. This creates a single policy that works for all teams without manual updates. Option A gives too broad access. Option C is not a valid policy mechanism. Option D is insecure and not scalable.
