Use this screenshot to answer the question below:
Where on this page would you click to view a secret located at secret/my-secret?
- A. D
- B. B
- C. A
- D. C
- E. E
Answer: D
Explanation:
In the HashiCorp Vault UI, secrets are organized in a tree-like structure. To view a secret located at secret/my-secret, you would click on the "secret/" folder in the tree, then click on the "my-secret" file. In this screenshot, the "secret/" folder is located at option C. This folder contains the secrets that are stored in the key/value secrets engine, which is the default secrets engine in Vault. The key/value secrets engine allows you to store arbitrary secrets as key/value pairs. The key is the path of the secret, and the value is the data of the secret. For example, the secret located at secret/my-secret has a key of "my-secret" and a value of whatever data you stored there.

NEW QUESTION # 29
What is the Vault CLI command to query information about the token the client is currently using?
- A. vault self-lookup
- B. vault lookup self
- C. vault token lookup
- D. vault lookup token
Answer: C
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 # 30
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 # 31
When creating a policy, an error was thrown:
Which statement describes the fix for this issue?
- A. Replace write with create in the capabilities list
- B. sudo is not a capability
- C. You cannot have a wildcard (" * ") in the path
Answer: A
Explanation:
The error was thrown because the policy code contains an invalid capability, "write". The valid capabilities for a policy are "create", "read", "update", "delete", "list", and "sudo". The "write" capability is not recognized by Vault and should be replaced with "create", which allows creating new secrets or overwriting existing ones. The other statements are not correct, because the wildcard (*) and the sudo capability are both valid in a policy. The wildcard matches any number of characters within a path segment, and the sudo capability allows performing certain operations that require root privileges.

NEW QUESTION # 32
Which of the following statements describe the secrets engine in Vault? Choose three correct answers.
- A. You can build your own custom secrets engine
- B. A secrets engine cannot be enabled at multiple paths
- C. Once enabled, you cannot disable the secrets engine
- D. Each secrets engine is isolated to its path
- E. Some secrets engines simply store and read data
Answer: A,D,E
Explanation:
Secrets engines are components that store, generate, or encrypt data in Vault. They are enabled at a specific path in Vault and have their own API and configuration. Some of the statements that describe the secrets engines in Vault are:
Some secrets engines simply store and read data, such as the key/value secrets engine, which acts like an encrypted Redis or Memcached. Other secrets engines perform more complex operations, such as generating dynamic credentials, encrypting data, issuing certificates, etc1.
You can build your own custom secrets engine by using the plugin system, which allows you to write and run your own secrets engine as a separate process that communicates with Vault over gRPC. You can also use the SDK to create your own secrets engine in Go and compile it into Vault2.
Each secrets engine is isolated to its path, which means that the secrets engine cannot access or interact with other secrets engines or data outside its path. The path where the secrets engine is enabled can be customized and can have multiple segments. For example, you can enable the AWS secrets engine at aws/ or aws/prod/ or aws/dev/3.
The statements that are not true about the secrets engines in Vault are:
You can disable an existing secrets engine by using the vault secrets disable command or the sys/mounts API endpoint. When a secrets engine is disabled, all of its secrets are revoked and all of its data is deleted from the storage backend4.
A secrets engine can be enabled at multiple paths, with a few exceptions, such as the system and identity secrets engines. Each secrets engine enabled at a different path is independent and isolated from others. For example, you can enable the KV secrets engine at kv/ and secret/ and they will not share any data3.
NEW QUESTION # 33
What is a benefit of response wrapping?
- A. Log every use of a secret
- B. Load balanc secret generation across a Vault cluster
- C. Ensure that only a single party can ever unwrap the token and see what's inside
- D. Provide error recovery to a secret so it is not corrupted in transit
Answer: C
Explanation:
Response wrapping is a feature that allows Vault to take the response it would have sent to a client and instead insert it into the cubbyhole of a single-use token, returning that token instead. The client can then unwrap the token and retrieve the original response. Response wrapping has several benefits, such as providing cover, malfeasance detection, and lifetime limitation for the secret data. One of the benefits is to ensure that only a single party can ever unwrap the token and see what's inside, as the token can be used only once and cannot be unwrapped by anyone else, even the root user or the creator of the token. This provides a way to securely distribute secrets to the intended recipients and detect any tampering or interception along the way5.
The other options are not benefits of response wrapping:
Log every use of a secret: Response wrapping does not log every use of a secret, as the secret is not directly exposed to the client or the network. However, Vault does log the creation and deletion of the response-wrapping token, and the client can use the audit device to log the unwrapping operation6.
Load balance secret generation across a Vault cluster: Response wrapping does not load balance secret generation across a Vault cluster, as the secret is generated by the Vault server that receives the request and the response-wrapping token is bound to that server. However, Vault does support high availability and replication modes that can distribute the load and improve the performance of the cluster7.
Provide error recovery to a secret so it is not corrupted in transit: Response wrapping does not provide error recovery to a secret so it is not corrupted in transit, as the secret is encrypted and stored in the cubbyhole of the token and cannot be modified or corrupted by anyone. However, if the token is lost or expired, the secret cannot be recovered either, so the client should have a backup or retry mechanism to handle such cases.
NEW QUESTION # 34
You can build a high availability Vault cluster with any storage backend.
- A. False
- B. True
Answer: A
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 # 35
To give a role the ability to display or output all of the end points under the /secrets/apps/* end point it would need to have which capability set?
- A. list
- B. update
- C. sudo
- D. read
- E. None of the above
Answer: C
Explanation:
To give a role the ability to display or output all of the end points under the /secrets/apps/* end point, it would need to have the list capability set. The list capability allows a role to perform any operation on any path in Vault, including reading, writing, deleting, and listing. The list capability is required for roles that need to access sensitive data or perform administrative tasks in Vault. The other capabilities are not relevant for this scenario, as they only allow specific operations on specific paths or secrets engines.

NEW QUESTION # 36
Which of the following statements describe the CLI command below?
S vault login -method-1dap username-mitche11h
- A. Generates a token which is response wrapped
- B. You will be prompted to enter the password
- C. Fails because the password is not provided
- D. By default the generated token is valid for 24 hours
Answer: A
Explanation:
The CLI command vault login -method ldap username=mitchellh generates a token that is response wrapped. This means that the token contains a base64-encoded response wrapper, which is a JSON object that contains information about the token, such as its policies, metadata, and expiration time. The response wrapper is used to verify the authenticity and integrity of the token, and to prevent replay attacks. The response wrapper also allows Vault to automatically renew the token when it expires, or to revoke it if it is compromised. The -method ldap option specifies that the authentication method is LDAP, which requires a username and password to be provided. The username mitchellh is an example of an LDAP user name, and the password will be hidden when entered.

NEW QUESTION # 37
When using Integrated Storage, which of the following should you do to recover from possible data loss?
- A. Use audit logs
- B. Failover to a standby node
- C. Use snapshot
- D. Use server 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 # 38
Which of the following vault lease operations uses a lease _ id as an argument? Choose two correct answers.
- A. create
- B. revoke -prefix
- C. describe
- D. revoke
- E. renew
Answer: D,E
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 # 39
Which of the following statements are true about Vault policies? Choose two correct answers.
- A. Policies deny by default (empty policy grants no permission)
- B. Vault must be restarted in order for a policy change to take an effect
- C. Policies provide a declarative way to grant or forbid access to certain paths and operations in Vault
- D. The default policy can not be modified
- E. You must use YAML to define policies
Answer: A,C
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 # 40
How many Shamir's key shares are required to unseal a Vault instance?
- A. The threshold number of key shares
- B. A quorum of key shares
- C. All key shares
- D. One or more keys
Answer: A
Explanation:
Shamir's Secret Sharing is a cryptographic algorithm that allows a secret to be split into multiple parts, called key shares, such that a certain number of key shares are required to reconstruct the secret. The number of key shares and the threshold number are configurable parameters that depend on the desired level of security and availability. Vault uses Shamir's Secret Sharing to protect its master key, which is used to encrypt and decrypt the data encryption key that secures the Vault data. When Vault is initialized, it generates a master key and splits it into a configured number of key shares, which are then distributed to trusted operators. To unseal Vault, the threshold number of key shares must be provided to reconstruct the master key and decrypt the data encryption key. This process ensures that no single operator can access the Vault data without the cooperation of other key holders.

NEW QUESTION # 41
Which of the following are replication methods available in Vault Enterprise? Choose two correct answers.
- A. Namespaces
- B. Disaster Recovery Replication
- C. Cluster sharding
- D. Performance 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 # 42
What can be used to limit the scope of a credential breach?
- A. Enable audit logging
- B. Use of a short-lived dynamic secrets
- C. Storage of secrets in a distributed ledger
- D. Sharing credentials between applications
Answer: B
Explanation:
Using a short-lived dynamic secrets can help limit the scope of a credential breach by reducing the exposure time of the secrets. Dynamic secrets are generated on-demand by Vault and automatically revoked when they are no longer needed. This way, the credentials are not stored in plain text or in a static database, and they can be rotated frequently to prevent unauthorized access. Dynamic secrets also provide encryption as a service, which means that they perform cryptographic operations on data in-transit without storing any data. This adds an extra layer of security and reduces the risk of data leakage or tampering.

NEW QUESTION # 43
Vault supports which type of configuration for source limited token?
- A. CIDR-bound tokens
- B. Cloud-bound tokens
- C. Certificate-bound tokens
- D. Domain-bound tokens
Answer: A
Explanation:
Vault supports CIDR-bound tokens, which are tokens that can only be used from a specific set of IP addresses or network ranges. This is a way to limit the scope and exposure of a token in case it is compromised or leaked. CIDR-bound tokens can be created by specifying the bound_cidr_list parameter when creating or updating a token role, or by using the -bound-cidr option when creating a token using the vault token create command. CIDR-bound tokens can also be created by some auth methods, such as AWS or Kubernetes, that can automatically bind the tokens to the source IP or network of the client.

NEW QUESTION # 44
Running the second command in the GUI CLI will succeed.
- A. False
- B. True
Answer: A
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 # 45
The key/value v2 secrets engine is enabled at secret/ See the following policy:
Which of the following operations are permitted by this policy? Choose two correct answers.
- A. vault kv get secret/webapp1
- B. vault kv put secret/webapp1 apikey-"ABCDEFGHI] K123M"
- C. vault kv metadata get secret/webapp1
- D. vault kv list secret/super-secret
- E. vault kv delete secret/super-secret
Answer: A,C
Explanation:
The policy shown in the image is:
path "secret/data/webapp1" { capabilities = ["create", "read", "update", "delete", "list"] } path "secret/data/super-secret" { capabilities = ["deny"] } This policy grants or denies access to the key/value v2 secrets engine mounted at secret/ according to the following rules:
The path "secret/data/webapp1" has the capabilities of "create", "read", "update", "delete", and "list". This means that the policy allows performing any of these operations on the secrets stored under this path. The data/ prefix is used to access the actual secret data in the key/value v2 secrets engine5. Therefore, the policy permits the operation of vault kv get secret/webapp1, which reads the secret data at secret/data/webapp16.
The path "secret/data/super-secret" has the capability of "deny". This means that the policy denies performing any operation on the secrets stored under this path. The policy overrides any other policy that might grant access to this path. Therefore, the policy does not permit the operations of vault kv delete secret/super-secret and vault kv list secret/super-secret, which delete and list the secret data at secret/data/super-secret respectively6.
The policy does not explicitly define any rules for the path "secret/metadata". The metadata/ prefix is used to access the metadata of the secrets in the key/value v2 secrets engine, such as the number of versions, the deletion status, the creation time, etc5. By default, if the policy grants any of the capabilities of "create", "read", "update", or "delete" on the data/ path, it also grants the same capabilities on the corresponding metadata/ path7. Therefore, the policy permits the operation of vault kv metadata get secret/webapp1, which reads the metadata of the secret at secret/metadata/webapp18.
NEW QUESTION # 46
Which of the following is a machine-oriented Vault authentication backend?
- A. Transit
- B. AppRole
- C. GitHub
- D. Okta
Answer: B
Explanation:
AppRole is a machine-oriented authentication method that allows machines or applications to authenticate with Vault using a role ID and a secret ID. The role ID is a unique identifier for the application, and the secret ID is a single-use credential that can be delivered to the application securely. AppRole is designed to provide secure introduction of machines and applications to Vault, and to support the principle of least privilege by allowing fine-grained access control policies to be attached to each role1.
Okta, GitHub, and Transit are not machine-oriented authentication methods. Okta and GitHub are user-oriented authentication methods that allow users to authenticate with Vault using their Okta or GitHub credentials23. Transit is not an authentication method at all, but a secrets engine that provides encryption as a service4.

NEW QUESTION # 47
You are using Vault's Transit secrets engine to encrypt your dat
a. You want to reduce the amount of content encrypted with a single key in case the key gets compromised. How would you do this?
- A. Periodically re-key the Vault's unseal keys
- B. Periodically rotate the encryption key
- C. Use 4096-bit RSA key to encrypt the data
- D. Upgrade to Vault Enterprise and integrate with HSM
Answer: B
Explanation:
The Transit secrets engine supports the rotation of encryption keys, which allows you to change the key that is used to encrypt new data without affecting the ability to decrypt data that was already encrypted. This reduces the amount of content encrypted with a single key in case the key gets compromised, and also helps you comply with the NIST guidelines for key rotation. You can rotate the encryption key manually by invoking the /transit/keys/<name>/rotate endpoint, or you can configure the key to automatically rotate based on a time interval or a number of encryption operations. When you rotate a key, Vault generates a new key version and increments the key's latest_version metadata. The new key version becomes the encryption key used for encrypting any new data. The previous key versions are still available for decrypting the existing data, unless you specify a minimum decryption version to archive the old key versions. You can also delete or disable old key versions if you want to revoke access to the data encrypted with those versions.
