NEW QUESTION # 31
What command creates a secret with the key "my-password" and the value "53cr3t" at path "my-secrets" within the KV secrets engine mounted at "secret"?
- A. vault kv write secret/my-secrets/my-password 53cr3t
- B. vault kv write 53cr3t my-secrets/my-password
- C. vault kv put secret/my-secrets/my-password-53cr3t
- D. vault kv put secret/my-secrets/my-password 53cr3t
Answer: D
Explanation:
The vault kv put command writes the data to the given path in the K/V secrets engine. The command requires the mount path of the K/V secrets engine, the secret path, and the key-value pair to store. The mount path can be specified with the -mount flag or as part of the secret path. The key-value pair can be given as an argument or read from a file or stdin. The correct syntax for the command is:
vault kv put -mount=secret my-secrets/my-password 53cr3t
or
vault kv put secret/my-secrets my-password=53cr3t
The other options are incorrect because they use the deprecated vault kv write command, or they have the wrong order or format of the arguments. Reference: https://developer.hashicorp.com/vault/docs/commands/kv/put3, https://developer.hashicorp.com/vault/docs/commands/kv4
NEW QUESTION # 32
Which of the following are replication methods available in Vault Enterprise? Choose two correct answers.
- A. Cluster sharding
- B. Performance Replication
- C. Namespaces
- D. Disaster Recovery Replication
Answer: B,D
Explanation:
The replication methods available in Vault Enterprise are performance replication and disaster recovery replication. These methods allow critical data to be replicated across clusters to support horizontally scaling and disaster recovery workloads.
Performance replication enables a primary cluster to replicate data to one or more secondary clusters, which can handle client requests and improve performance and availability. Performance replication replicates most Vault data, such as secrets, policies, auth methods, and leases, but not tokens. Performance secondaries generate their own tokens and leases, which are not replicated back to the primary. Performance replication also supports filtering, which allows selective replication of data based on namespaces or paths.
Disaster recovery replication enables a primary cluster to replicate data to one or more secondary clusters, which act as standby clusters in case of a failure or outage of the primary. Disaster recovery replication replicates all Vault data, including tokens and leases, and maintains the same configuration and state as the primary. Disaster recovery secondaries do not handle client requests, but they can be promoted to a primary in a disaster recovery scenario.

NEW QUESTION # 33
Which of the following statements are true about Vault policies? Choose two correct answers.
- A. You must use YAML to define policies
- B. The default policy can not be modified
- C. Vault must be restarted in order for a policy change to take an effect
- D. Policies provide a declarative way to grant or forbid access to certain paths and operations in Vault
- E. Policies deny by default (empty policy grants no permission)
Answer: D,E
Explanation:
Vault policies are written in HCL or JSON format and are attached to tokens or roles by name. Policies define the permissions and restrictions for accessing and performing operations on certain paths and secrets in Vault. Policies are deny by default, which means that an empty policy grants no permission in the system, and any request that is not explicitly allowed by a policy is implicitly denied1. Some of the features and benefits of Vault policies are:
Policies are path-based, which means that they match the request path to a set of rules that specify the allowed or denied capabilities, such as create, read, update, delete, list, sudo, etc2.
Policies are additive, which means that if a token or a role has multiple policies attached, the effective policy is the union of all the individual policies. The most permissive capability is granted if there is a conflict3.
Policies can use glob patterns, such as * and +, to match multiple paths or segments with a single rule. For example, path "secret/*" matches any path starting with secret/, and path "secret/+/config" matches any path with two segments after secret/ and ending with config4.
Policies can use templating to interpolate certain values into the rules, such as identity information, time, randomness, etc. For example, path "secret/{{identity.entity.id}}/*" matches any path starting with secret/ followed by the entity ID of the requester5.
Policies can be managed by using the vault policy commands or the sys/policy API endpoints. You can write, read, list, and delete policies by using these interfaces6.
The default policy is a built-in policy that is attached to all tokens by default and cannot be deleted. However, the default policy can be modified by using the vault policy write command or the sys/policy API endpoint. The default policy provides common permissions for tokens, such as renewing themselves, looking up their own information, creating and managing response-wrapping tokens, etc7.
You do not have to use YAML to define policies, as Vault supports both HCL and JSON formats. HCL is a human-friendly configuration language that is also JSON compatible, which means that JSON can be used as a valid input for policies as well8.
Vault does not need to be restarted in order for a policy change to take effect, as policies are stored and evaluated in memory. Any change to a policy is immediately reflected in the system, and any token or role that has that policy attached will be affected by the change.
NEW QUESTION # 34
Which of these are a benefit of using the Vault Agent?
- A. Vault Agent will auto-discover which authentication mechanism to use
- B. Vault Agent will manage the lifecycle of cached tokens and leases automatically
- C. Vault Agent will enforce minimum levels of encryption an application can use
- D. Vault Agent allows for centralized configuration of application secrets engines
Answer: B
Explanation:
Vault Agent is a client daemon that provides the following features:
Auto-Auth - Automatically authenticate to Vault and manage the token renewal process for locally-retrieved dynamic secrets.
API Proxy - Allows Vault Agent to act as a proxy for Vault's API, optionally using (or forcing the use of) the Auto-Auth token.
Caching - Allows client-side caching of responses containing newly created tokens and responses containing leased secrets generated off of these newly created tokens. The agent also manages the renewals of the cached tokens and leases.
Templating - Allows rendering of user-supplied templates by Vault Agent, using the token generated by the Auto-Auth step.
Process Supervisor Mode - Runs a child process with Vault secrets injected as environment variables.
One of the benefits of using the Vault Agent is that it will manage the lifecycle of cached tokens and leases automatically. This means that the agent will handle the token renewal and revocation logic, as well as the lease renewal and revocation logic for the secrets that are cached by the agent. This reduces the burden on the application developers and operators, and ensures that the tokens and secrets are always valid and up-to-date.

NEW QUESTION # 35
Examine the command below. Output has been trimmed.
Which of the following statements describe the command and its output?
- A. Generated token's TTL is 60 hours
- B. Missing a default token policy
- C. Configures the AppRole auth method with user specified role ID and secret ID
- D. Generated token is an orphan token which can be renewed indefinitely
Answer: A,D
Explanation:
The command shown in the image is:
vault token create -policy=approle -orphan -period=60h
This command creates a new token with the following characteristics:
It has the policy "approle" attached to it, which grants or denies access to certain paths and operations in Vault according to the policy rules. The policy can be defined by using the vault policy write command or the sys/policy API endpoint12.
It is an orphan token, which means it has no parent token and it will not be revoked when its parent token is revoked. Orphan tokens can be useful for creating long-lived tokens that are not affected by the token hierarchy3.
It has a period of 60 hours, which means it has a renewable TTL of 60 hours. This means that the token can be renewed indefinitely as long as it does not go past the 60-hour mark from the last renewal time. The token's TTL will be reset to 60 hours upon each renewal. Periodic tokens are useful for creating tokens that have a fixed lifetime and can be easily revoked4.
NEW QUESTION # 36
An organization would like to use a scheduler to track & revoke access granted to a job (by Vault) at completion. What auth-associated Vault object should be tracked to enable this behavior?
- A. Authentication method
- B. Token accessor
- C. Token ID
- D. Lease ID
Answer: D
Explanation:
A lease ID is a unique identifier that is assigned by Vault to every dynamic secret and service type authentication token. A lease ID contains information such as the secret path, the secret version, the secret type, etc. A lease ID can be used to track and revoke access granted to a job by Vault at completion, as it allows the scheduler to perform the following operations:
Lookup the lease information by using the vault lease lookup command or the sys/leases/lookup API endpoint. This will return the metadata of the lease, such as the expire time, the issue time, the renewable status, and the TTL.
Renew the lease if needed by using the vault lease renew command or the sys/leases/renew API endpoint. This will extend the validity of the secret or the token for a specified increment, or reset the TTL to the original value if no increment is given.
Revoke the lease when the job is completed by using the vault lease revoke command or the sys/leases/revoke API endpoint. This will invalidate the secret or the token immediately and prevent any further renewals. For example, with the AWS secrets engine, the access keys will be deleted from AWS the moment a lease is revoked.
A lease ID is different from a token ID or a token accessor. A token ID is the actual value of the token that is used to authenticate to Vault and perform requests. A token ID should be treated as a secret and protected from unauthorized access. A token accessor is a secondary identifier of the token that is used for token management without revealing the token ID. A token accessor can be used to lookup, renew, or revoke a token, but not to authenticate to Vault or access secrets. A token ID or a token accessor can be used to revoke the token itself, but not the leases associated with the token. To revoke the leases, a lease ID is required.
An authentication method is a way to verify the identity of a user or a machine and issue a token with appropriate policies and metadata. An authentication method is not an object that can be tracked or revoked, but a configuration that can be enabled, disabled, tuned, or customized by using the vault auth commands or the sys/auth API endpoints.
NEW QUESTION # 37
The following three policies exist in Vault. What do these policies allow an organization to do?
- A. Nothing, as the minimum permissions to perform useful tasks are not present
- B. Create a transit encryption key for encrypting, decrypting, and rewrapping encrypted data
- C. Encrypt, decrypt, and rewrap data using the transit engine all in one policy
- D. Separates permissions allowed on actions associated with the transit secret engine
Answer: C
Explanation:
The three policies that exist in Vault are:
admins: This policy grants full access to all secrets and operations in Vault. It can be used by administrators or operators who need to manage all aspects of Vault.
default: This policy grants access to all secrets and operations in Vault except for those that require specific policies. It can be used as a fallback policy when no other policy matches.
transit: This policy grants access only to the transit secrets engine, which handles cryptographic functions on data in-transit. It can be used by applications or services that need to encrypt or decrypt data using Vault.
These policies allow an organization to perform useful tasks such as:
Encrypting, decrypting, and rewrapping data using the transit engine all in one policy: This policy grants access to both the transit secrets engine and the default policy, which allows performing any operation on any secret in Vault.
Creating a transit encryption key for encrypting, decrypting, and rewrapping encrypted data: This policy grants access only to the transit secrets engine and its associated keys, which are used for encrypting and decrypting data in transit using AES-GCM with a 256-bit AES key or other supported key types.
Separating permissions allowed on actions associated with the transit secret engine: This policy grants access only to specific actions related to the transit secrets engine, such as creating keys or wrapping requests. It does not grant access to other operations or secrets in Vault.
NEW QUESTION # 38
What is the Vault CLI command to query information about the token the client is currently using?
- A. vault lookup self
- B. vault lookup token
- C. vault self-lookup
- D. vault token lookup
Answer: D
Explanation:
The Vault CLI command to query information about the token the client is currently using is vault token lookup. This command displays information about the token or accessor provided as an argument, or the locally authenticated token if no argument is given. The information includes the token ID, accessor, policies, TTL, creation time, and metadata. This command can be useful for debugging and auditing purposes, as well as for renewing or revoking tokens.

NEW QUESTION # 39
Running the second command in the GUI CLI will succeed.
- A. True
- B. False
Answer: B
Explanation:
Running the second command in the GUI CLI will fail. The second command is vault kv put secret/creds passcode=my-long-passcode. This command attempts to write a secret named creds with the value passcode=my-long-passcode to the secret path, which is the default path for the kv secrets engine. However, the kv secrets engine is not enabled at the secret path, as shown by the first command vault secrets list, which lists the enabled secrets engines and their paths. The only enabled secrets engine is the transit secrets engine at the transit path. Therefore, the second command will fail with an error message saying that no secrets engine is mounted at the path secret/. To make the second command succeed, the kv secrets engine must be enabled at the secret path or another path, using the vault secrets enable command. For example, vault secrets enable -path=secret kv would enable the kv secrets engine at the secret path.

NEW QUESTION # 40
Which Vault secret engine may be used to build your own internal certificate authority?
- A. PKI
- B. Transit
- C. PostgreSQL
- D. Generic
Answer: A
Explanation:
The Vault secret engine that can be used to build your own internal certificate authority is the PKI secret engine. The PKI secret engine generates dynamic X.509 certificates on-demand, without requiring manual processes of generating private keys and CSRs, submitting to a CA, and waiting for verification and signing. The PKI secret engine can act as a root CA or an intermediate CA, and can issue certificates for various purposes, such as TLS, code signing, email encryption, etc. The PKI secret engine can also manage the certificate lifecycle, such as rotation, revocation, renewal, and CRL generation. The PKI secret engine can also integrate with external CAs, such as Venafi or Entrust, to delegate the certificate issuance and management.

NEW QUESTION # 41
Which of the following cannot define the maximum time-to-live (TTL) for a token?
- A. By the authentication method t natively provide a method of expiring credentials
- B. A parent token TTL e password rotation tools and practices
- C. System max TTL
- D. By the client system f credentials leaking
- E. By the mount endpoint configuration very password used
Answer: D
Explanation:
The maximum time-to-live (TTL) for a token is defined by the lowest value among the following factors:
The authentication method that issued the token. Each auth method can have a default and a maximum TTL for the tokens it generates. These values can be configured by the auth method's mount options or by the auth method's specific endpoints.
The mount endpoint configuration that the token is accessing. Each secrets engine can have a default and a maximum TTL for the leases it grants. These values can be configured by the secrets engine's mount options or by the secrets engine's specific endpoints.
A parent token TTL. If a token is created by another token, it inherits the remaining TTL of its parent token, unless the parent token has an infinite TTL (such as the root token). A child token cannot outlive its parent token.
System max TTL. This is a global limit for all tokens and leases in Vault. It can be configured by the system backend's max_lease_ttl option.
The client system that uses the token cannot define the maximum TTL for the token, as this is determined by Vault's configuration and policies. The client system can only request a specific TTL for the token, but this request is subject to the limits imposed by the factors above.
NEW QUESTION # 42
Where does the Vault Agent store its cache?
- A. In memory
- B. In the Vault key/value store
- C. In an unencrypted file
- D. In a file encrypted using the Vault transit secret engine
Answer: A
Explanation:
The Vault Agent stores its cache in memory, which means that it does not persist the cached tokens and secrets to disk or any other storage backend. This makes the cache more secure and performant, as it avoids exposing the sensitive data to potential attackers or unauthorized access. However, this also means that the cache is volatile and will be lost if the agent process is terminated or restarted. To mitigate this, the agent can optionally use a persistent cache file to restore the tokens and leases from a previous agent process. The persistent cache file is encrypted using a key derived from the agent's auto-auth token and a nonce, and it is stored in a user-specified location on disk.

NEW QUESTION # 43
Your organization has an initiative to reduce and ultimately remove the use of long lived X.509 certificates. Which secrets engine will best support this use case?
- A. PKI
- B. Transit
- C. Key/Value secrets engine version 2, with TTL defined
- D. Cloud KMS
Answer: A
Explanation:
The PKI secrets engine is designed to support the use case of reducing and ultimately removing the use of long lived X.509 certificates. The PKI secrets engine can generate dynamic X.509 certificates on demand, with short time-to-live (TTL) and automatic revocation. This eliminates the need for manual processes of generating, signing, and rotating certificates, and reduces the risk of certificate compromise or misuse. The PKI secrets engine can also act as a certificate authority (CA) or an intermediate CA, and can integrate with external CAs or CRLs. The PKI secrets engine can issue certificates for various purposes, such as TLS, SSH, code signing, email encryption, etc. Reference: https://developer.hashicorp.com/vault/docs/secrets/pki1, https://developer.hashicorp.com/vault/tutorials/getting-started/getting-started-dynamic-secrets
NEW QUESTION # 44
As a best practice, the root token should be stored in which of the following ways?
- A. Should be revoked and never stored after initial setup
- B. Should be stored in Vault
- C. Should be stored in another password safe
- D. Should be stored in configuration automation tooling
Answer: A
Explanation:
The root token is the initial token created when initializing Vault. It has unlimited privileges and can perform any operation in Vault. As a best practice, the root token should be revoked and never stored after initial setup. This is because the root token is a single point of failure and a potential security risk if it is compromised or leaked. Instead of using the root token, Vault operators should create other tokens with appropriate policies and roles that allow them to perform their tasks. If a new root token is needed in an emergency, the vault operator generate-root command can be used to create one on-the-fly with the consent of a quorum of unseal key holders.

NEW QUESTION # 45
You can build a high availability Vault cluster with any storage backend.
- A. True
- B. False
Answer: B
Explanation:
Not all storage backends support high availability mode for Vault. Only the storage backends that support locking can enable Vault to run in a multi-server mode where one server is active and the others are standby. Some examples of storage backends that support high availability mode are Consul, Integrated Storage, and ZooKeeper. Some examples of storage backends that do not support high availability mode are Filesystem, MySQL, and PostgreSQL.

NEW QUESTION # 46
Which of the following vault lease operations uses a lease _ id as an argument? Choose two correct answers.
- A. describe
- B. revoke -prefix
- C. renew
- D. revoke
- E. create
Answer: C,D
Explanation:
The vault lease operations that use a lease_id as an argument are renew and revoke. The renew operation allows a client to extend the validity of a lease associated with a secret or a token. The revoke operation allows a client to terminate a lease immediately and invalidate the secret or the token. Both operations require a lease_id as an argument to identify the lease to be renewed or revoked. The lease_id can be obtained from the response of reading a secret or creating a token, or from the vault lease list command. The other operations, revoke-prefix, create, and describe, do not use a lease_id as an argument. The revoke-prefix operation allows a client to revoke all secrets or tokens generated under a given prefix. The create operation allows a client to create a new lease for a secret. The describe operation allows a client to view information about a lease, such as its TTL, policies, and metadata.

NEW QUESTION # 47
When using Integrated Storage, which of the following should you do to recover from possible data loss?
- A. Use server logs
- B. Failover to a standby node
- C. Use snapshot
- D. Use audit logs
Answer: C
Explanation:
Integrated Storage is a Raft-based storage backend that allows Vault to store its data internally without relying on an external storage system. It also enables Vault to run in high availability mode with automatic leader election and failover. However, Integrated Storage is not immune to data loss or corruption due to hardware failures, network partitions, or human errors. Therefore, it is recommended to use the snapshot feature to backup and restore the Vault data periodically or on demand. A snapshot is a point-in-time capture of the entire Vault data, including the encrypted secrets, the configuration, and the metadata. Snapshots can be taken and restored using the vault operator raft snapshot command or the sys/storage/raft/snapshot API endpoint. Snapshots are encrypted and can only be restored with a quorum of unseal keys or recovery keys. Snapshots are also portable and can be used to migrate data between different Vault clusters or storage backends. Reference: https://developer.hashicorp.com/vault/docs/concepts/integrated-storage1, https://developer.hashicorp.com/vault/docs/commands/operator/raft/snapshot2, https://developer.hashicorp.com/vault/api-docs/system/storage/raft/snapshot3
NEW QUESTION # 48
When an auth method is disabled all users authenticated via that method lose access.
- A. True
- B. False
Answer: A
Explanation:
The statement is true. When an auth method is disabled, all users authenticated via that method lose access. This is because the tokens issued by the auth method are automatically revoked when the auth method is disabled. This prevents the users from performing any operation in Vault using the revoked tokens. To regain access, the users have to authenticate again using a different auth method that is enabled and has the appropriate policies attached. Reference: Auth Methods | Vault | HashiCorp Developer, auth disable - Command | Vault | HashiCorp Developer
NEW QUESTION # 49
What does the following policy do?
- A. Grants access to a special system entity folder
- B. Grants access for each user to a KV folder which shares their id
- C. Allows a user to read data about the secret endpoint identity
- D. Nothing, this is not a valid policy
Answer: C
Explanation:
This policy allows a user to read data about the secret endpoint identity. The policy grants the user the ability to create, update, read, and delete data in the "secret/data/{identity.entity.id}" path. Additionally, the user is allowed to list data in the "secret/metadata/{identity.entity.id}" path. This policy is useful for users who need to access information about the secret endpoint identity.
The secret endpoint identity is a feature of the Identity Secrets Engine, which allows Vault to generate identity tokens that can be used to access other Vault secrets engines or namespaces. The identity tokens are based on the entity and group information of the user or machine that authenticates with Vault. The entity is a unique identifier for the user or machine, and the group is a collection of entities that share some common attributes. The identity tokens can carry metadata and policies that are associated with the entity and group.
The "secret/data/{identity.entity.id}" path is where the user can store and retrieve data that is related to the secret endpoint identity. For example, the user can store some configuration or preferences for the secret endpoint identity in this path. The "secret/metadata/{identity.entity.id}" path is where the user can list the metadata of the data stored in the "secret/data/{identity.entity.id}" path. For example, the user can list the version, creation time, deletion time, and destroy time of the data in this path.
