 The error message “psql: server closed the connection unexpectedly” means that the server terminated abnormally before or while processing the request. This is likely due to the Leader Load Balancer not being available on the port and replication cannot be established. The port that is the problem is 5432, which is the default port for PostgreSQL database connections. The Follower needs to connect to the Leader Load Balancer on this port to receive the replication data from the Leader. If the port is blocked or unreachable, the Follower will fail to sync with the Leader and display the error message. References: [Set up Follower], [Troubleshoot Follower]

This is the most likely cause of this issue because it creates a discrepancy between the passwords stored in the Primary Vault and the DR Vault, which affects the Vault Conjur Synchronizer service (Synchronizer) and the application. The Synchronizer is a service that synchronizes secrets from the CyberArk Vault to the Conjur database. The application is a client that retrieves secrets from the Conjur database using the Conjur REST API. The CPM is a component that manages the lifecycle of the passwords stored in the CyberArk Vault, such as changing, verifying, and reconciling them. If the CPM is writing password changes to the Primary Vault while the Synchronizer is configured to replicate from the DR Vault, the following scenario may occur:

The CPM changes the password for an account in the Primary Vault and updates the password value in the Vault database.

The Synchronizer does not detect the password change in the DR Vault, as the DR Vault database has not been updated yet with the new password value.

The Synchronizer does not sync the new password value to the Conjur database, as it assumes that the password value in the DR Vault database is the latest and correct one.

The application requests the password value from the Conjur database and receives the old password value, which is different from the new password value in the Primary Vault database.

The application tries to use the old password value to access the target platform or device and fails, as the target platform or device expects the new password value.

This answer is based on the CyberArk Secrets Manager documentation1 and the CyberArk Secrets Manager training course2.

The correct answer is A. On the new Leader, generate a Standby seed for the old Leader node and add it to the cluster member list. Rebuild the old Leader as a new Standby and then re-enroll the node to the cluster.

This is the recommended way to repair the cluster health after an auto-failover event, according to the CyberArk Sentry Secrets Manager documentation1. This method reuses the original Leader as a new Standby, without affecting the new Leader or the other Standby. The steps are as follows:

On the new Leader, generate a Standby seed for the old Leader node using the command evoke seed standby . This will create a file named .tar in the current directory.

On the new Leader, add the old Leader node to the cluster member list using the command evoke cluster add .

On the old Leader server, stop and remove the container using the commands docker stop  and docker rm .

On the old Leader server, copy the Standby seed file from the new Leader using the command scp :.tar .

On the old Leader server, create a new container using the same name as the one you just destroyed, and load the Standby seed file using the command docker run --name -d --restart=always -v /var/log/conjur:/var/log/conjur -v /opt/conjur/backup:/opt/conjur/backup -p "443:443" -p "5432:5432" -p "1999:1999" cyberark/conjur:latest seed fetch .tar

On the old Leader server, re-enroll the node to the cluster using the command evoke cluster enroll

The other options are not correct, as they either involve unnecessary or harmful steps, such as rebuilding the new Leader or the other Standby, or re-uploading the auto-failover policy in replace mode, which may cause data loss or inconsistency.

This is the correct answer because the Conjur Token is a JSON Web Token (JWT) that is signed by the Conjur master and contains the identity and permissions of the application. The Conjur Token is stateless, meaning that it does not depend on any stored session or transaction information on the server side. Therefore, any Conjur follower can validate the Token by verifying the signature and the expiration time, and satisfy the request by retrieving the credential from the local database. This allows the Conjur followers to be horizontally scalable and load balanced, and to provide high availability and performance for the applications. This answer is based on the Conjur documentation1 and the Conjur training course2.

According to the CyberArk Sentry Secrets Manager documentation, auto-failover is a feature that enables the automatic promotion of a standby node to a leader node in case of a leader failure. Auto-failover requires a quorum, which is a majority of nodes in the cluster that are available and synchronized. A quorum ensures that only one node can be promoted to a leader at a time and prevents split-brain scenarios. In the exhibit, each option shows a network diagram of a load balancer and four nodes, one of which is crossed out with a red X, indicating a leader failure. The text below each diagram indicates whether there is a quorum or not. Option C is the only example where auto-failover will occur, because there is a quorum of three out of four nodes, and one of the standby nodes can be promoted to a leader. Option A will not have auto-failover, because there is no quorum, as only two out of four nodes are available. Option B will not have auto-failover, because there is no quorum, as only one out of four nodes is available. Option D will not have auto-failover, because there is no quorum, as none of the nodes are available. References: 1: Auto-failover 2: Configure auto-failover

When an account or Safe is renamed in the Vault, the Vault Conjur Synchronizer will create new variables in Conjur with the new name and delete the old variables with the old name. This means that the permissions that were granted to the old variables in Conjur will not apply to the new variables, and they will need to be recreated using delegation policies. Otherwise, the users or hosts that had access to the old variables will not be able to access the new ones. References: Manage Accounts and Safes During Synchronization; Vault Synchronizer full policy guide

Conjur is a secrets management solution that securely stores and manages secrets and credentials used by applications, DevOps tools, and other systems. Conjur provides a REST API that enables users to perform various operations on Conjur objects, such as secrets, policies, roles, and resources. The API endpoint for each Conjur object is composed of the base URL of the Conjur server, followed by the object type and identifier. For example, the API endpoint for a secret named db-password in the dev/my-app policy is:

https:// /secrets/dev/my-app/db-password

To discover secrets inside of Conjur, the API endpoint that can be used is Resources. Resources are Conjur objects that have permissions and annotations associated with them, such as secrets, hosts, groups, and layers. The Resources API endpoint allows users to list, search, and filter resources based on various criteria, such as kind, owner, policy, and annotation. For example, the following API request will return a list of all secrets owned by the user alice:

https:// /resources?kind=variable&owner=user:alice

The Resources API endpoint can help users to discover secrets inside of Conjur by providing information such as the name, ID, policy, owner, and annotations of each secret. Users can also use the Resources API endpoint to check the permissions and audit records of each secret, and to retrieve the secret value if they have the read permission.

Create an authenticator policy for each authenticator and then load the policy to Conjur.

Add each authenticator to conjur.yml using this format: <authenticator type> .

Execute evoke configuration apply.

Comprehensive Explanation: Authenticators are plugins that enable Conjur to authenticate requests from different types of clients, such as Kubernetes, Azure, or LDAP. To configure authenticators, you need to follow these steps:

Create an authenticator policy for each authenticator and then load the policy to Conjur. This step defines the authenticator as a resource in Conjur and grants permissions to the users or hosts that can use it. You can use the policy templates provided by Conjur for each authenticator type, or create your own custom policy. For more information, see Define Authenticator Policy.

Add each authenticator to conjur.yml using this format: <authenticator type> . This step enables the authenticator service on the Conjur server and specifies the service ID that identifies the authenticator instance. The service ID must match the one used in the policy. For more information, see Enable Authenticators.

Execute evoke configuration apply. This step applies the changes made to the conjur.yml file and restarts the Conjur service. This is necessary for the authenticator configuration to take effect. For more information, see Apply Configuration Changes.
