The simplest solution is to use Conjur Summon. This approach externalizes the secret retrieval process from the script's logic. The PowerShell script only needs a minimal modification to read the credential from a standard environment variable instead of a hard-coded value. The summon command-line tool is then used to execute the script, securely fetching the required secret from Conjur and injecting it into the script's runtime environment. This decouples the application logic from the secrets management implementation, resulting in a cleaner and simpler script.

A. This is a viable but more complex solution. It requires modifying the script to make specific calls to the CyberArk CLI SDK, tightly coupling the script to the Credential Provider's implementation.

B. Implementing SOAP web service calls directly within a PowerShell script is significantly more complex than using a dedicated SDK or tool, requiring manual request building and XML parsing.

C. WebSphere is an application server and is entirely irrelevant for running a PowerShell script on workstations. This technology does not apply to the scenario.

1. Conjur Open Source Documentation

Summon: The documentation describes Summon as a command-line tool that makes secrets available to a process as environment variables. It highlights the use of a secrets.yml file for declarative mapping

which simplifies configuration. The core principle is to run a command in a sub-process with the fetched secrets

abstracting the retrieval mechanism from the application code itself. (Reference: Conjur.org Documentation

"Tools"

"Summon" section).

2. CyberArk Application Access Manager Documentation

Command Line Password SDK: The official documentation for the Credential Provider details the usage of CLIPasswordSDK.exe. The examples show that the script itself must be modified to explicitly call this executable with specific parameters (e.g.

AppID

Safe

Object) and then process the standard output to retrieve the password. This method embeds the secret retrieval logic directly into the script

making it more complex than reading an environment variable. (Reference: CyberArk Credential Provider & ASCP Implementation Guide

Chapter on "Command Line Password SDK").

According to official CyberArk documentation, the supported and required method for upgrading the Central Credential Provider (CCP) Web Service is to perform a complete uninstallation of the current version, followed by a fresh installation of the new version. This process ensures that all components are updated correctly and prevents potential conflicts or configuration issues that could arise from an in-place upgrade. The procedure involves stopping the IIS service, uninstalling the AimWebService application, and then running the installer for the new version to deploy the updated web service.

A. sudo yum update aimprv is a Linux command. The CCP Web Service is a component installed on a Windows IIS server.

B. The main Credential Provider installer is for the core agent, not the CCP Web Service, which is a separate component with its own installer (AimWebService.msi).

C. Running the AimWebService.msi to perform an in-place upgrade is not the officially documented or supported procedure; the correct process is uninstall and reinstall.

1. CyberArk Docs (Version 14.0)

"Credential Provider & ASCP Installation Guide"

Section: Install the Central Credential Provider

Subsection: Upgrade the Central Credential Provider. The guide explicitly states: "To upgrade the Central Credential Provider

you must first uninstall the existing version

and then install the new version." This confirms the uninstall/reinstall process.

2. CyberArk Docs (Version 13.2)

"Credential Provider & ASCP Installation Guide"

Section: Install the Central Credential Provider

Subsection: Upgrade the Central Credential Provider. The procedure is detailed as: "1. On the Credential Provider machine

stop the IIS server... 2. Uninstall the Central Credential Provider... 3. Install the new version of the Central Credential Provider...". This step-by-step instruction validates that an uninstall and reinstall is the correct method.

When an auto-failover occurs and a Standby is promoted to Leader, the old Leader is considered lost by the cluster. To reintroduce it, it must be rebuilt as a Standby. The correct procedure involves generating a new Standby seed file on the current Leader. This seed file contains the necessary configuration and certificates for the old Leader node to securely connect and synchronize with the new Leader. The old Leader node is then re-initialized as a Standby using this seed file, effectively re-enrolling it into the cluster in its new role.

B: This is incorrect because it describes rebuilding the newly promoted Leader, which is the active and functioning node. This would cause a service outage and is the opposite of the required repair.

C: This is incorrect as it suggests rebuilding both the new Leader and the other healthy Standby. This is a destructive and unnecessary action that would dismantle the entire working cluster.

D: This is incorrect because re-uploading the auto-failover policy is not a required step for re-enrolling a failed node. The seed generation process on the new Leader is sufficient to prepare the cluster for the new Standby.

1. CyberArk Conjur Enterprise Documentation v12.8

"Set up a High Availability Cluster" -> "Recover from a Leader failure". The official procedure states: "After a failover

the old Leader is no longer part of the cluster. To add it back to the cluster

you must reconfigure it as a Standby." The documented steps include generating a seed file on the new Leader for the old Leader's host

and then using that seed to configure the old Leader as a new Standby. This directly supports option A.

2. CyberArk Conjur Enterprise Documentation v12.8

"evoke command reference" -> "evoke seed standby". The documentation for this command specifies that it is run on the Leader to "generate and package the configuration files and certificates for a new Standby." This confirms that the new Leader must generate the seed for the node being re-enrolled.

The Conjur architecture utilizes a specific set of ports to maintain high availability and security across a distributed cluster. Port 443 is the primary interface for all HTTPS-based API calls and UI management. Port 444 is a specialized, unauthenticated port used by load balancers to perform health checks without requiring complex credentials. For internal database synchronization, Conjur relies on Port 5432, the standard for PostgreSQL, to replicate data from the Leader to Standbys and Followers. To maintain a centralized audit trail, Port 1999 is dedicated to streaming log data from downstream Followers back to the Leader. Finally, Port 22 is the standard port used for administrative SSH access to the server or container.

CyberArk Conjur Enterprise Documentation: System Requirements - Network Ports. This official resource lists all required ingress and egress ports for the Conjur cluster, including 443 (HTTPS), 444 (Health), 1999 (Audit), and 5432 (Replication).

CyberArk Docs: High Availability and Replication. This section details the PostgreSQL streaming replication mechanism and its reliance on the default database port (5432).

CyberArk Technical Support Knowledge Base: Load Balancer Configuration for Conjur. Explains the logic behind Port 444 for simple HTTP health probes.

PostgreSQL Global Development Group: Chapter 19. Server Configuration. Confirms 5432 as the default port for the communication between the primary database and its replicas.

In a CyberArk Conjur high-availability (HA) cluster, the architecture is designed for resilience using Leader and Standby nodes. The Leader is the single writable node, while Standby nodes are synchronous replicas. The primary function of a Standby is to be available for immediate promotion to the Leader role in the event of a failure of the active Leader. This promotion is the core mechanism of a failover, ensuring the continued availability of the Conjur service for write operations like policy updates. This process can be initiated automatically by a cluster manager or manually by an administrator.

B. A Follower is an asynchronous, read-only replica designed for scaling read-heavy workloads and cannot be promoted to a Leader, as it may not have the most current data.

C. This would be a role demotion or reconfiguration, not a promotion. A Standby has a higher-level HA function (synchronous replication) than a Follower (asynchronous replication).

D. During a failover, a Standby is promoted to Leader. The old, failed Leader, once recovered, can be configured to rejoin the cluster as a Standby, but this is a post-failover recovery step, not the failover event itself.

1. CyberArk Conjur Enterprise Documentation

"Conjur Cluster Architecture": This section explicitly describes the roles. It states

"The Leader and Standbys form a high availability (HA) cluster. If the Leader fails

a Standby is promoted to Leader. This can be done manually

or automatically using a cluster management tool... Followers are read-only asynchronous replicas of the Leader... Followers cannot be promoted to Leader."

2. CyberArk Conjur Enterprise Documentation

"Set up a High Availability Cluster": The procedure for handling a failover is detailed in the "Promote a Standby" section. It outlines the command evoke cluster promote which is used to perform this exact role change. This confirms that promoting a Standby to a Leader is a designed and documented operational capability.

3. CyberArk Conjur Enterprise Documentation

"Disaster Recovery": In the context of recovering a failed Leader

the documentation states: "When the original Leader is restored

it can be configured as a Standby in the cluster." This clarifies the lifecycle of a former Leader post-failure

distinguishing it from the initial failover action described in option A.
