VA-003 Manage Vault leases Practice Test 3 — 15 Questions

Question 1

A DevOps team is using Vault's database secrets engine to generate dynamic credentials for a PostgreSQL database. They notice that the lease duration is set to 24 hours, but security policy requires that credentials expire after 1 hour. What should the team do to enforce the 1-hour expiration without changing the default lease TTL for all secrets?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Configure the role with a ttl of 1h.. The database secrets engine allows role-level TTL configuration that overrides the default lease duration for credentials generated from that role. By setting the role's `ttl` to 1h, the team enforces a 1-hour expiration for credentials created under that specific role without affecting the default lease TTL for all secrets or other roles. This directly meets the security policy requirement while maintaining flexibility for other secrets.

Answer

Set the mount's max_lease_ttl to 1h.

Answer

Ask each developer to set the TTL when requesting credentials.

Answer

Use a periodic token with a period of 1h.

Question 2

An organization uses Vault to issue certificates via the PKI secrets engine. They have set the default lease TTL on the PKI mount to 72h, and the role's ttl to 24h. A user requests a certificate with a requested TTL of 48h. What will be the actual TTL of the issued certificate?

Accepted Answer

24h. (24h) because when a certificate request is made, Vault applies the most restrictive TTL among the role's configured `ttl`, the mount's default lease TTL, and the requested TTL. Here, the role's `ttl` of 24h is the shortest, so it overrides both the requested 48h and the mount default of 72h, resulting in a certificate with a 24-hour validity.

Answer

The request will be rejected because the requested TTL exceeds the role's ttl.

Answer

48h

Answer

72h

Question 3

Which TWO of the following actions can reduce the number of active leases in Vault? (Select two.)

Accepted Answer

Reducing the default lease TTL. Option A is correct because reducing the default lease TTL shortens the lifetime of newly issued leases, so they expire and are revoked sooner, decreasing the count of active leases at any given time. Option B is correct because revoking a lease explicitly invalidates it, immediately removing it from the set of active leases tracked by Vault. Option C is incorrect because creating a new lease adds another active lease rather than reducing the count. Option D is incorrect because increasing the max lease TTL allows leases to live longer, which tends to keep more leases active. Option E is incorrect because renewing a lease extends its lifetime, keeping it active instead of reducing the number of active leases.

Answer

Creating a new lease

Answer

Increasing the max lease TTL

Answer

Renewing a lease

Question 4

An organization uses Vault's AWS secrets engine to generate temporary IAM credentials. The Vault administrator has set the default lease TTL on the AWS mount to 15 minutes. A developer creates a role with role TTL of 30 minutes and explicit max TTL of 1 hour. Which TWO statements are true regarding the lease behavior for credentials generated under this role?

Accepted Answer

The initial lease duration will be 30 minutes (the role TTL).. Option A is correct because when a role specifies its own TTL, that role TTL overrides the mount's default lease TTL, so the initial lease duration for credentials generated under this role is 30 minutes. Option B is correct because the role's explicit max TTL of 1 hour caps the total lifetime of the lease, meaning renewals can extend it only up to that 1-hour maximum. Option D is incorrect because the 15-minute default lease TTL applies only when the role does not define its own TTL. Option C is incorrect because an explicit max TTL prevents indefinite renewal and overrides the system max TTL. Option E is incorrect because Vault does not take the minimum of the default lease TTL and role TTL; the role TTL takes precedence for the initial lease duration.

Answer

The lease can be renewed indefinitely up to the system max TTL.

Answer

The initial lease duration will be 15 minutes (the default lease TTL).

Answer

The lease duration is the minimum of default lease and role TTL.

Question 5

Drag and drop the steps to configure Vault's audit logging to a file into the correct order.

Accepted Answer

Enable audit device, then perform operations to generate log entries, then verify the audit log.. The correct sequence for configuring Vault's audit logging to a file is: first enable the audit device (e.g., 'vault audit enable file file_path=...'), then perform operations (e.g., read/write secrets) to generate audit log entries, and finally verify the log file to confirm entries are being recorded. Common mistakes include enabling after generating logs, verifying too early, or skipping the generation step.

Answer

Perform operations to generate log entries, then enable audit device, then verify the audit log.

Answer

Verify audit log, then enable audit device, then perform operations to generate log entries.

Answer

Enable audit device, then verify the audit log, then perform operations to generate log entries.

Question 6

Match each Vault term to its definition.

Accepted Answer

Secret: A piece of sensitive data stored in Vault. Correct matches: Secret is sensitive data; Token is an authentication credential. Common confusions: Policy vs. Auth Method — policies control access, auth methods authenticate users.

Answer

Policy: A method used to authenticate a user or machine to Vault

Answer

Auth Method: A set of rules defining access permissions in Vault

Question 7

An administrator notices that after revoking a specific lease, the underlying database credential is still accessible. What is the most likely cause?

Accepted Answer

The revocation script failed to delete the database user.. When a lease is revoked in Vault, the revocation script associated with the database secret engine is responsible for deleting or disabling the corresponding database user. If that script fails (e.g., due to insufficient permissions, network issues, or a bug in the script), the underlying credential remains active in the database, even though the lease is no longer valid in Vault. This is a common operational issue where the lease lifecycle and the actual credential lifecycle become out of sync.

Answer

The secret engine caches credentials.

Answer

The lease ID was incorrect.

Answer

The lease was renewed after revocation.

Question 8

What command is used to view the remaining time on a lease?

Accepted Answer

vault lease lookup . The correct command to view the remaining time on a lease is `vault lease lookup `. This command retrieves the lease metadata, including the issue time, duration (TTL), and remaining time, directly from the Vault server. It is the standard method for inspecting lease details without extending or modifying the lease.

Answer

vault lease info <lease_id>

Answer

vault status <lease_id>

Answer

vault read <lease_id>

Question 9

A Vault cluster is sealed. An operator attempts to renew a lease but gets an error. What is the most likely error?

Accepted Answer

Vault is sealed. When Vault is sealed, it cannot process any operations, including lease renewal. The error would indicate the sealed state.

Answer

Upstream error

Answer

Permission denied

Answer

Lease not found

Question 10

A developer wants to ensure that their application automatically renews its secret leases before expiration. Which approach is recommended?

Accepted Answer

Use Vault agent with a template and renew capability.. Vault Agent's template and renew capability is the recommended approach because it automatically manages the lifecycle of dynamic secrets, including renewing leases before they expire. Vault Agent runs as a sidecar or daemon and uses its built-in renewer to periodically extend the lease TTL, ensuring the application always has a valid secret without manual intervention or external scheduling.

Answer

Set the lease TTL to infinite.

Answer

Use a cron job to call vault lease renew periodically.

Answer

Use periodic tokens with auto-renewal.

Question 11

Which of the following best describes a Vault lease?

Accepted Answer

A time-limited agreement that governs the lifecycle of a secret.. A Vault lease is a time-bound agreement that governs the lifecycle of a secret, including its validity period, renewal, and revocation. When a secret is read from Vault, it is returned with a lease ID and a lease duration (TTL), after which the secret is automatically revoked unless renewed. This ensures that secrets are not valid indefinitely, reducing the risk of exposure.

Answer

A permission to access a path.

Answer

A contract to use a secret for a certain duration.

Answer

The actual secret value.

Question 12

An operator runs vault lease list and sees many expired leases. Why are expired leases still listed?

Accepted Answer

Vault keeps expired leases for auditing until cleaned up by garbage collection.. Vault does not immediately remove expired leases; they are cleaned up by a periodic garbage collection process. Until then, they may appear in listing.

Answer

The leases are not actually expired.

Answer

The operator has a permission to see expired leases.

Answer

Expired leases are never removed.

Question 13

What happens when a lease reaches its TTL?

Accepted Answer

The lease is marked as expired and can no longer be renewed.. When a lease reaches its Time-To-Live (TTL), it becomes expired and cannot be renewed. Vault does not automatically delete the lease from storage at the moment of TTL expiry; rather, the lease is marked as expired and is eventually garbage-collected. This cleanup is separate from revocation of the underlying secret, which must be performed explicitly or via a different mechanism.

Answer

The lease is automatically renewed.

Answer

The secret is automatically revoked.

Answer

The lease is deleted from storage.

Question 14

After a Vault migration, some leases are no longer valid and cause errors. What is the best way to force a cleanup of all leases under a specific mount without affecting other mounts?

Accepted Answer

Use vault lease revoke -prefix . The `vault lease revoke -prefix ` command is specifically designed to revoke all leases associated with a given mount path without affecting other mounts. This command iterates through all leases under that prefix and forces their revocation, cleaning up invalid leases efficiently. It is the targeted, non-disruptive approach for lease cleanup in Vault.

Answer

Restart Vault servers

Answer

Disable and re-enable the secret engine

Answer

Reduce the mount's max_lease_ttl to 0

Question 15

Which two commands can be used to manually revoke leases? (Choose two.)

Accepted Answer

vault lease revoke . Option C, `vault lease revoke `, is correct because it directly revokes a single lease by its lease ID, immediately invalidating the associated secret and removing it from Vault's lease tracking. Option E, `vault lease revoke -prefix `, is correct because the `-prefix` flag revokes all leases whose IDs begin with the given prefix, enabling bulk revocation of leases under a path or hierarchy. Option A, `vault secrets disable `, is not a lease-revocation command; it disables a secrets engine at the given path, which revokes leases as a side effect but is not the manual lease-revocation operation asked for. Option B, `vault token revoke `, revokes a token and its child tokens, not leases directly. Option D, `vault lease renew `, extends a lease's TTL rather than revoking it.

Answer

vault secrets disable <path>

Answer

vault token revoke <token>

Answer

vault lease renew <lease_id>
