Question 1hardmultiple choice
Full question →

A company uses HashiCorp Vault in production to manage secrets for its microservices. One microservice, 'order-svc', authenticates via AppRole and receives a service token with a TTL of 24 hours and a max TTL of 48 hours. Over the past few days, operations teams report that 'order-svc' fails to renew its token after approximately 23 hours, causing authentication failures. The token lookup shows the token is still alive with about 1 hour of TTL remaining, but renewal attempts return a 'permission denied' error. The Vault audit logs show the renewal request is reaching Vault and being denied. The token's policies include 'path "auth/token/renew-self" { capabilities = ["update"] }'. The token was created with the default options. What is the most likely cause of this failure?

A DevOps team uses Vault to manage secrets for a microservices application. The application authenticates to Vault using AppRole, and each service obtains a periodic token with a TTL of 24 hours and a period of 1 hour. The tokens are used to read secrets from a path. Recently, the team noticed that some services are unable to read secrets after a few hours, with error messages indicating that the token is not authorized or has expired. Upon investigation, the team finds that the tokens are being renewed properly but still fail after some time. What is the most likely cause of this issue?

A company uses Kubernetes auth. A pod in namespace 'prod' with service account 'my-sa' can authenticate and read secrets. After upgrading the Kubernetes cluster, the same pod fails to authenticate with error 'JWT token issuer is not valid'. What is the most likely cause?

An application using a service token fails to renew it, receiving an error 'permission denied'. The token has policies that include 'path "auth/token/renew-self" { capabilities = ["update"] }'. The token is not expired and has remaining TTL. What is a likely cause?

An organization uses Vault with LDAP authentication. Users report they are unable to log in, and the administrator sees errors like 'LDAP bind failed: invalid credentials' in the Vault logs. The LDAP server is reachable. What is the most likely cause?

A DevOps engineer is troubleshooting an issue where a token cannot read a secret from the KV v2 engine at path 'secret/team-alpha/db-creds'. The token's policy includes the following: path "secret/team-alpha/*" { capabilities = ["read"] }. Which TWO reasons could explain the failure?

Question 8mediummultiple choice

An organization uses Vault's AWS secret engine to dynamically generate IAM credentials. The application uses the API to request credentials by calling 'POST /v1/aws/creds/my-role'. Recently, the application started receiving '400 Bad Request' with error 'invalid role ARN'. The role 'my-role' is defined in Vault and has been working for months. The administrator checks the role configuration and confirms the ARN is correct and that the associated IAM policy exists in AWS. The Vault server logs show no connectivity issues with AWS. The application code has not changed. What is the most likely cause?

Question 9mediummultiple choice

An administrator configured the database secrets engine with PostgreSQL. When an application requests credentials, Vault returns a username and password. However, the application reports that the credentials are not working. What is the most likely cause?

An organization uses Vault with AWS IAM auth. After rotating the AWS IAM role credentials, users are unable to authenticate with Vault. The Vault audit logs show 'permission denied' for the AWS auth method. What is the most likely cause?

Question 11mediummultiple choice

A large e-commerce company uses Vault to manage secrets for their AWS EC2 instances. They use AWS IAM auth. The Vault role is configured with bound_iam_role_arn to match the IAM role 'ec2-app-role'. Most instances work fine. However, a new instance launched with the same IAM role fails to authenticate. The instance can reach Vault (network is fine) and the AWS credentials are valid. The Vault server logs show: 'error validating login: unable to get instance identity document'. The new instance is in a different AWS region (us-west-2) while most others are in us-east-1. Vault is deployed in us-east-1. What is the most likely cause and solution?

A DevOps engineer is troubleshooting a Vault CLI command that is failing with the error 'Error writing data: Error making API request'. The engineer has verified that the Vault token is valid and unexpired. Which of the following is the most likely cause of this error?

Question 13mediummultiple choice
Full question →

A DevOps team is managing secrets for a microservices application using Vault. They have created a policy named 'app-policy' that grants read access to secrets under the path 'secret/data/app/*'. The policy is assigned to an AppRole role. When a service authenticates with the role ID and secret ID, it receives a token but is unable to read secrets from 'secret/data/app/db-creds'. The token's identity metadata shows the policies associated with the token include 'default' and 'app-policy'. The Vault server logs show no errors. The service can successfully read other secrets from the same path, like 'secret/data/app/config'. What is the most likely cause of the issue?

A developer is troubleshooting an application that uses Vault's PostgreSQL secrets engine. The application successfully obtains a database credential from Vault, but after 30 minutes, the application starts receiving authentication errors from the database. The developer checks the Vault audit logs and sees that the lease for the credential was revoked. The lease was originally created with a TTL of 1 hour. The application is not renewing the lease. The developer wants to fix the issue so that the credential works for the full 1 hour. What should the developer do?

A DevOps engineer is troubleshooting a script that uses the Vault CLI to authenticate and read a secret. The script works when run manually from a terminal, but fails when executed by a CI/CD pipeline. The engineer has verified that the same environment variables (VAULT_ADDR, VAULT_TOKEN) are set in both environments. Which two of the following are likely causes of the failure? (Choose two.)
