This VA-003 practice question tests your understanding of manage vault leases. 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.
An admin needs to revoke all leases associated with a particular policy violation. Which two methods can be used? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
vault write sys/leases/revoke-prefix <prefix>
Both `vault lease revoke -prefix <prefix>` and `vault write sys/leases/revoke-prefix <prefix>` will revoke all leases with the given prefix, which can target the mount or role involved in the policy violation. Option A revokes a specific lease only. Option B revokes a token and its leases, but not specifically by policy prefix. Option E has an incorrect path.
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.
✗
vault sys/leases/revoke-force <prefix>
Why it's wrong here
Incorrect path; there is no revoke-force endpoint.
✗
vault token revoke -mode=orphan <token>
Why it's wrong here
Orphan mode revokes the token but leaves its leases intact; not suitable for revoking leases.
✗
vault lease revoke <lease_id>
Why it's wrong here
Only revokes a single lease, not all associated with a policy.
✓
vault write sys/leases/revoke-prefix <prefix>
Why this is correct
API equivalent to revoke by prefix.
Related concept
Static NAT maps one inside address to one outside address.
✓
vault lease revoke -prefix <mount_path>
Why this is correct
Revokes all leases under the given prefix.
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: vault write sys/leases/revoke-prefix <prefix> — Both `vault lease revoke -prefix <prefix>` and `vault write sys/leases/revoke-prefix <prefix>` will revoke all leases with the given prefix, which can target the mount or role involved in the policy violation. Option A revokes a specific lease only. Option B revokes a token and its leases, but not specifically by policy prefix. Option E has an incorrect path.
