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.

Question 9mediummultiple 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?

Question 10mediummultiple choice
Full question →

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?

A Vault administrator is troubleshooting an issue where after a network outage, the Vault cluster is sealed and cannot be unsealed. The cluster has 5 nodes using Integrated Storage. The administrator runs `vault status` on each node and receives 'sealed' response. The administrator suspects that the cluster lost quorum during the outage. The administrator checks the Raft configuration and finds that there are 3 voter nodes and 2 non-voter nodes. Which action should the administrator take to recover the cluster?

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?
