B. Review the log file ‘CreateEnv.log’ and investigate any error messages it contains.

This is the best option because the CreateEnv.log file records the steps and results of creating the CP environment in the Vault during the installation. The CP environment includes the safe, the provider user, the application user, and the application identity. If any errors occurred when creating the CP environment, they will be logged in this file and may indicate a problem with the Vault connection, the credential file, the permissions, or the configuration. Reviewing the log file can help to identify and resolve the root cause of the errors and ensure the CP environment is properly set up.

Continuing configuring the application to use the CP without further action is not a good option because it may lead to unexpected or inconsistent behavior of the CP or the application. The errors that occurred when creating the CP environment may affect the security, availability, or integrity of the credentials or the application. Ignoring the errors may also make it harder to troubleshoot or fix them later.

Running setup.exe again and selecting ‘Recreate Vault Environment’ is not a good option because it may overwrite or delete the existing CP environment and cause more errors or conflicts. Recreating the Vault environment should only be done after reviewing the log file and understanding the cause of the errors. Moreover, recreating the Vault environment may require more privileges than creating it for the first time, as some objects may be already in use or locked.

Reviewing the PVWA logs to determine which REST API call used during the installation failed is not a good option because it may not provide enough information or context to understand or resolve the errors. The PVWA logs may show the HTTP status codes or messages of the REST API calls, but they may not show the details or parameters of the calls or the responses. The PVWA logs may also contain other unrelated or irrelevant entries that may confuse or distract from the errors. The CreateEnv.log file is a more specific and reliable source of information for the errors that occurred when creating the CP environment.

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.

Conjur Followers are read-only replicas of the Leader that can serve client requests for authentication, authorization, and secret retrieval. However, Followers cannot perform write operations, such as creating or updating secrets, policies, or roles. If the Leader becomes unavailable, the Followers will not be able to sync with the latest data and will eventually become stale. To ensure high availability and data consistency, the customer should extend the auto-failover cluster to include Standbys in each data center. Standbys are also replicas of the Leader, but they can participate in replication and promotion. One Standby is configured for synchronous replication, which means it receives the same updates as the Leader at the same time. The other Standbys are configured for asynchronous replication, which means they receive updates from the Leader periodically, but not in real time. In case of Leader failure, the synchronous Standby can be automatically promoted to become the new Leader, and one of the asynchronous Standbys can become the new synchronous Standby. This way, the customer can ensure that there is always an up-to-date Leader that can serve write requests and sync with the Followers in different data centers. References: Set up Follower, Set up auto-failover cluster, Conjur architecture and deployment reference

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.

According to the CyberArk Sentry Secrets Manager documentation, Conjur is a secrets management solution that consists of a leader node and one or more follower nodes. The leader node is responsible for managing the secrets, policies, and audit records, while the follower nodes are read-only replicas that can serve secrets requests from applications. To achieve high availability in AWS cloud infrastructure, the minimally viable Conjur deployment architecture is to have one follower in each availability zone (AZ) and a load balancer for the region. This way, if one AZ fails, the applications can still access secrets from another AZ through the load balancer. Having two followers in each region, load balanced for the region, is not enough to ensure high availability, as a regional outage can affect both followers. Having two followers in each AZ, load balanced for the region, is more than necessary, as one follower per AZ can handle the secrets requests. Having two followers in each region, load balanced across all regions, is not feasible, as Conjur does not support cross-region replication. References: 1: Conjur Architecture 2: Deploying Conjur on AWS

= The cause of the issue is that the token is not correctly encoded. A token is a string of characters that represents a credential or an authorization grant for accessing a resource. A token must be encoded according to a specific format and standard, such as Base64, JSON Web Token (JWT), or OAuth 2.0. If the token is malformed, meaning that it does not follow the expected format or standard, the server will reject the token and return an error 401 - Malformed Authorization Token. This error indicates that the token is invalid or expired, and the request is unauthorized. To resolve the issue, the token must be regenerated or refreshed using the correct encoding method and parameters12. References: =

• CyberArk Identity: Getting 401 unauthorized Error when using API calls with OAuth2 Client 2, Resolution 1
• Troubleshoot CyberArk Vault Synchronizer 1, Error: Forbidden Logon Token is Empty - Cannot logon Unauthorized

The log entry shows a failed authentication attempt with Conjur using the authn-jwt method. This method allows applications to authenticate with Conjur using JSON Web Tokens (JWTs) that are signed by a trusted identity provider. In this case, the application is Jenkins, which is a CI/CD tool that can integrate with Conjur using the Conjur Jenkins plugin. The plugin allows Jenkins to securely retrieve secrets from Conjur and inject them as environment variables into Jenkins pipelines or projects.

The log entry indicates that the JWT sent by Jenkins was rejected by Conjur because of an SSL connection error. The error message says that the certificate chain of Jenkins could not be verified by Conjur, and that the certificate authority (CA) that signed the Jenkins certificate was unknown to Conjur. This means that the Jenkins certificate chain is not trusted by Conjur, and that Conjur does not have the CA certificate of Jenkins in its trust store. Therefore, Conjur cannot establish a secure and trusted connection with Jenkins, and cannot validate the JWT signature.

To fix this problem, the Jenkins certificate chain needs to be trusted by Conjur. This can be done by copying the CA certificate of Jenkins to the Conjur server, and adding it to the Conjur trust store. The Conjur trust store is a directory that contains the CA certificates of the trusted identity providers for the authn-jwt method. The Conjur server also needs to be restarted for the changes to take effect.

To upgrade an HA Conjur cluster, you need to follow these steps:

• Stop and rename the Conjur Leader container and then start the new Leader. This step ensures that you have a backup of the old Leader container in case something goes wrong with the upgrade. You also need to specify the hostname and master-altnames parameters when starting the new Leader container to match the load balancer and the cluster nodes.
• Restore the Leader from backup. This step restores the data and configuration from the old Leader to the new Leader. You need to use the evoke restore command with the backup file name and the account name as arguments.
• Redeploy to the Standbys. This step upgrades the Standbys to the same version as the Leader. You need to stop and rename the old Standby containers and then start the new Standby containers with the evoke configure standby command. You also need to specify the hostname of the Leader and the Standby as arguments.
• Enroll the Leader and Standbys into the auto-failover cluster. This step enables the auto-failover feature for the cluster, which allows the Standbys to automatically take over the role of the Leader in case of a failure. You need to use the evoke cluster enroll command on the Leader and the evoke cluster join command on the Standbys. You also need to provide the hostname and password of the Leader as arguments.

 = This error occurs when the Vault Conjur Synchronizer installation script tries to log in to the Vault using the admin user credentials, but the admin user is already logged in to other sessions. The Vault has a limit on the number of concurrent sessions per user, and the default value is one. Therefore, the installation script fails to authenticate the admin user and returns the error message: Forbidden Logon Token is Empty - Cannot logon Unauthorized. To remediate the issue, the admin user must log out of any other sessions before running the installation script, or increase the limit on the number of concurrent sessions per user in the Vault configuration file12. References: =

= Summon is a command-line tool that provides on-demand secrets access for common DevOps tools. It reads a file in secrets.yml format and injects secrets as environment variables into any process. The secrets.yml file is where you define which secrets to retrieve from a trusted store, such as CyberArk Secrets Manager. The secrets.yml file specifies the name and location of each secret, as well as the environment variable to assign it to. For example, a secrets.yml file could look like this:

DB_USERNAME: !var dev/my-app/db-username DB_PASSWORD: !var dev/my-app/db-password

This means that Summon will fetch the values of dev/my-app/db-username and dev/my-app/db-password from the trusted store, and assign them to the environment variables DB_USERNAME and DB_PASSWORD, respectively. Then, Summon will run the specified process with these environment variables set, and remove them once the process exits. This way, Summon enables secure and convenient access to secrets without exposing them in plain text or storing them in files.

Based on the image you sent, the correct network port to its function in Conjur are:

• 22: required for SSH access
• 443: TLS endpoint for Conjur UI and API
• 444: HTTP health endpoint: simplifies load balancer setup
• 1999: audit events are streamed from the Follower to the Leader (using syslog-ng)
• 5432: required for data replication from the Leader to Standbys and Followers (PostgreSQL)

These are the standard ports and protocols used by the Conjur components to communicate with each other and with external clients. The ports can be customized according to the network and security requirements of the organization. These ports are documented in the CyberArk Secrets Manager documentation1 and the CyberArk Secrets Manager training course2.

o enable synchronous replication on a Conjur cluster, you need to run the command evoke replication sync that on the Leader node of the cluster. This command will configure the Leader to wait for confirmation from all Standbys before committing any transaction to the database. This ensures that the data is consistent across all nodes and prevents data loss in case of a failover. However, this also increases the latency and reduces the throughput of the cluster, so it should be used with caution and only when required by the business or compliance needs.

C. docker exec evoke ca import – –no-restart

This is the correct command to import the root CA certificate into Conjur. The evoke ca import command is used to import a certificate authority (CA) certificate into the Conjur appliance. The certificate can be either a root CA or an intermediate CA. The – –no-restart option prevents the Conjur appliance from restarting after importing the certificate. The parameter specifies the path and name of the root CA certificate file to be imported. This command will add the root CA certificate to the trusted CA store of the Conjur appliance, which is used to validate the certificates of the clients and servers that communicate with Conjur. This command is documented in the Conjur documentation1 and the Conjur training course2.

The other options are not correct commands to import the root CA certificate into Conjur. The evoke import command does not exist. The – –root option is not a valid option for the evoke ca import command. The ca import command is not a valid docker exec command.

This is the correct answer because the Conjur CLI is a tool that allows users to interact with the Conjur REST API from the command line. The Conjur CLI can be run on Windows, Red Hat Enterprise Linux, and macOS operating systems, as well as in Docker containers. The Conjur CLI can be installed using various methods, such as downloading the executable file, using a package manager, or pulling the Docker image. The Conjur CLI supports Conjur Enterprise 12.9 or later versions. This answer is based on the CyberArk Secrets Manager documentation1 and the CyberArk Secrets Manager training course2.

The other options are not true statements for the Conjur CLI. The Conjur CLI can be run from any machine that has network access to the Conjur server, not only from the Conjur Leader node. The Conjur Leader node is the node that performs read/write operations on the Conjur database and policy engine, and hosts the Conjur UI and API endpoints. The Conjur CLI is not required for working with the Conjur REST API, as users can also use other tools, such as curl, Postman, or web browsers, to send HTTP requests to the Conjur REST API. The Conjur CLI does implement the Conjur REST API for managing Conjur resources, such as roles, policies, secrets, and audit records. The Conjur CLI provides a set of commands that correspond to the Conjur REST API endpoints and allow users to perform various operations on the Conjur resources.

This is the correct answer because the Vault.ini file on the CP machine contains the configuration settings for the CP to connect to the Vault server. The Address parameter specifies the IP address or hostname of the Vault server that the CP will use to communicate with the Vault. In the event of a failover of the Vault server from the primary to the DR, the CP needs to update the Address parameter with the IP address of the DR Vault server in order to continue being able to refresh its cache. The cache is a local storage of credentials that the CP retrieves from the Vault and provides to the applications. The cache is refreshed periodically based on the RefreshInterval parameter in the Vault.ini file. This answer is based on the CyberArk Secrets Manager documentation1 and the CyberArk Secrets Manager training course2.

The other options are not correct because they do not ensure that the CP will continue being able to refresh its cache in the event of a failover of the Vault server from the primary to the DR. Adding the DR Vault IP address to the Address parameter in the main_appprovider.conf.. file in the AppProviderConf safe is not a valid option, as this file does not contain the Address parameter. The main_appprovider.conf file contains the configuration settings for the basic provider, such as the AppProviderVaultParmsFile, the AppProviderPort, and the AppProviderCacheMode. The Address parameter is only found in the Vault.ini file on the CP machine.

In the Password Vault Web Access (PVWA) UI, adding the IP address of the DR Vault in the Disaster Recovery section under Applications > Options is not a valid option, as this section does not exist in the PVWA UI. The PVWA UI does not have a Disaster Recovery section under Applications > Options. The PVWA UI has a Disaster Recovery section under Administration > Options, but this section is used to configure the DR Vault settings, such as the DR Vault IP address, the DR Vault user, and the DR Vault password. These settings are not related to the CP configuration or cache refresh.

In the Conjur UI, adding the IP address of the DR Vault in the Disaster Recovery section under Cluster Config > Credential Provider > Options is not a valid option, as this section does not exist in the Conjur UI. The Conjur UI does not have a Cluster Config, Credential Provider, or Options section. The Conjur UI has a Cluster Config section under Settings, but this section is used to configure the Conjur cluster settings, such as the master IP address, the follower IP address, and the seed fetcher IP address. These settings are not related to the CP configuration or cache refresh.
