• Question 31:

  In a 3-node auto-failover cluster, the Leader has been brought down for patching that lasts longer than the configured TTL. A Standby has been promoted.

  Which steps are required to repair the cluster when the old Leader is brought back online?

  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.
  B. Generate a Standby seed for the newly promoted Leader. Stop and remove the container on the new Leader, then rebuild it as a new Standby. Re-enroll the Standby to the cluster and re-base replication of the 3rd Standby back to the old Leader.
  C. Generate standby seeds for the newly-promoted Leader and the 3rd Standby Stop and remove the containers and then rebuild them as new Standbys. On both new Standbys, re-enroll the node to the cluster.
  D. On the new Leader, generate a Standby seed for the old Leader node and re-upload the auto-failover policy in "replace" mode. Rebuild the old Leader as a new Standby, then re-enroll the node to the cluster.
  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.

  ---

  Explanation/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.

• Question 32:

  When using the Seed Fetcher to deploy Kubernetes Followers, an error occurs in the Seed Fetcher container. You check the logs and discover that although the Seed Fetcher was able to authenticate, it shows a 500 error in the log and does not successfully retrieve a seed file. What is the cause?

  A. The certificate based on the Follower DNS name is not present on the Leader.
  B. The host you configured does not have access to see the certificates.
  C. The synchronizer service crashed and needs to be restarted.
  D. The Leader does not have the authenticator webservice enabled.
  A. The certificate based on the Follower DNS name is not present on the Leader.

  ---

  Explanation/Reference:

  The cause of the issue is A. The certificate based on the Follower DNS name is not present on the Leader. This means that the Leader does not have a certificate file that matches the Follower DNS name used in the seed request, and therefore cannot generate a valid seed file for the Follower. This results in a 500 error in the Seed Fetcher container log. To resolve the issue, you need to import a certificate with the Follower DNS name as the subject alt name on the Leader, and create a copy of the certificate file with a name that matches the Follower DNS name used in the seed request1.

• Question 33:

  When attempting to retrieve a credential, you receive an error 401 ?Malformed Authorization Token.

  What is the cause of the issue?

  A. The token is not correctly encoded.
  B. The token you are trying to retrieve does not exist.
  C. The host does not have access to the credential with the current token.
  D. The credential has not been initialized.
  A. The token is not correctly encoded.

  ---

  Explanation/Reference:

  = 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.

• Question 34:

  When loading policy, you receive a 422 Response from Conjur with a message.

  What could cause this issue?

  A. malformed Policy file
  B. incorrect Leader URL
  C. misconfigured Load Balancer health check
  D. incorrect Vault Conjur Synchronizer URL
  A. malformed Policy file

  ---

  Explanation/Reference:

  The most likely cause for this issue is A. malformed Policy file. A 422 Response from Conjur indicates that the request was well-formed but was unable to be followed due to semantic errors. A common semantic error when loading policy is having a malformed Policy file, which means that the Policy file does not follow the correct syntax, structure, or logic of the Conjur Policy language. A malformed Policy file can result from typos, missing or extra characters, incorrect indentation, invalid references, or other mistakes that prevent Conjur from parsing and applying the Policy file. The message that accompanies the 422 Response will usually provide more details about the error and the location of the problem in the Policy file. To resolve this issue, you should review the Policy file and check for any errors or inconsistencies. You can use a YAML validator or a text editor with syntax highlighting to help you identify and correct any syntax errors. You can also use the Conjur Policy Simulator to test and debug your Policy file before loading it to Conjur. The Conjur Policy Simulator is a web-based tool that allows you to upload your Policy file and see how it will affect the Conjur data model, without actually loading it to Conjur. You can also use the Conjur Policy Simulator to compare different versions of your Policy file and see the changes and conflicts between them. For more information, refer to the following resources: Policy - CyberArk, Section "Policy" Policy Language - CyberArk, Section "Policy Language" Conjur Policy Simulator - CyberArk, Section "Conjur Policy Simulator"

• Question 35:

  Where can all the self-signed/imported certificates be found in Conjur?

  A. /opt/conjur/etc/ssl from the Conjur containers
  B. /opt/conjur/certificates from the Conjur containers
  C. /opt/cyberark/dap/certs from the Conjur containers
  D. Log in to the Conjur UI > Conjur Cluster > Certificates > view.
  A. /opt/conjur/etc/ssl from the Conjur containers

  ---

  Explanation/Reference:

  Conjur uses TLS certificates for authentication between nodes and clients. These certificates are either self-signed by Conjur or imported from a third-party CA. All the certificates are stored in the /opt/conjur/etc/ssl directory from the Conjur

  containers. This directory contains the following files:

  ca.crt: The CA certificate used to verify all Conjur node certificates. This is either the self-signed Conjur CA certificate or the imported third-party CA certificate. server.crt: The server certificate used by the Conjur node for HTTPS and mTLS

  connections. This certificate contains the DNS names of the node and the load balancer in the CN and SAN fields.

  server.key: The private key corresponding to the server certificate. cert.pem: A symbolic link to the server certificate file. key.pem: A symbolic link to the server key file. References: Certificate architecture, Certificate requirements, Rotate

• Question 36:

  DRAG DROP

  You are configuring the Conjur Cluster with 3rd-party certificates.

  Arrange the steps to accomplish this in the correct sequence.

  Select and Place:

  

  

  ---

  Explanation/Reference:

  The correct sequence of steps to configure the Conjur Cluster with 3rd-party certificates is as follows: Import 3rd-party certificates to the Leader using the command: docker exec mycontainer evoke ca import --force --root --chain 1 Configure the Leader using the command: docker exec mycontainer evoke configure master --accept-eula --hostname --admin-password 1 Verify the Conjur Leader configuration using the command: docker exec mycontainer evoke role Configure the Standbys using the command: docker exec mycontainer evoke configure standby --master-address --master-fingerprint 1 References: Certificate requirements

• Question 37:

  DRAG DROP

  Arrange the manual failover configuration steps in the correct sequence.

  Select and Place:

  

  

  ---

  Explanation/Reference:

  In the event of a Leader failure, you can perform a manual failover to promote one of the Standbys to be the new Leader. The manual failover process consists of the following steps:

  Suspend replication for all Standbys and Followers and identify the best failover candidate. This step ensures that no data is lost or corrupted during the failover process. The best failover candidate is the Standby with the most advanced replication timeline, which means it has the most up-to-date data from the Leader. Promote the failover candidate to be the new Leader. This step changes the role of the failover candidate from a Standby to a Leader, and updates its configuration accordingly. The new Leader can now accept write requests from clients and replicate data to other nodes.

  Restore replication. This step re-establishes the replication connections between the new Leader and the other nodes, and rebases the replication of the other Standbys and Followers to the new Leader. This ensures that all nodes have the same data and are in sync with the new Leader.

• Question 38:

  Refer to the exhibit.

  

  How can you confirm that the Follower has a current copy of the database?

  A. Compare the pgcurrentxlog_locationlocation from the Leader to the Follower you need to validate against.
  B. Count the number of components in pgstartreplication and compare this to the total number of Followers in the deployment.
  C. Validate that the Follower container ID matches the node in the info endpoint on the Leader.
  D. Retrieve the credential from a test application on the Leader cluster; then retrieve against the Follower and compare if they are accurate.
  A. Compare the pgcurrentxlog_locationlocation from the Leader to the Follower you need to validate against.

  ---

  Explanation/Reference:

  The exhibit shows a JSON object that contains the replication status of a database in a Secrets Manager cluster. Secrets Manager is a secrets management solution that securely stores and manages secrets and credentials used by applications, DevOps tools, and other systems. Secrets Manager can be deployed in a cluster mode, which consists of a Leader node and one or more Follower nodes. The Leader node is the primary node that handles all write operations and coordinates the replication of data to the Follower nodes. The Follower nodes are read-only nodes that replicate data from the Leader node and serve requests from clients and applications that need to retrieve secrets or perform other read-only operations. To confirm that the Follower has a current copy of the database, you can compare the pgcurrentxlog_locationlocation from the Leader to the Follower you need to validate against. The pgcurrentxlog_locationlocation is a property that indicates the current position of the write-ahead log (WAL) in the database. The WAL is a mechanism that records all changes made to the database in a sequential log file, before they are applied to the actual data files. The WAL ensures the durability and consistency of the database in case of a crash or a power failure. The WAL also enables the replication of data from the Leader node to the Follower nodes, by streaming the WAL records to the Follower nodes and applying them to their local databases. By comparing the pgcurrentxlog_locationlocation from the Leader to the Follower, you can determine how far behind the Follower is from the Leader in terms of the WAL records. If the pgcurrentxlog_locationlocation values are identical or very close, it means that the Follower has a current copy of the database, and that the replication is working properly. If the pgcurrentxlog_locationlocation values are different or far apart, it means that the Follower has an outdated copy of the database, and that there is a replication lag or a replication failure. In that case, you may need to troubleshoot the replication issue and resolve it as soon as possible.

• Question 39:

  What does "Line of business (LOB)" represent?

  A. a business group requiring access to secrets from the Vault/Privilege Claud to facilitate syncing accounts to Conjur
  B. the services that Conjur offers and typically refers to a group of application identities in Conjur
  C. a business group that meets a certain set of Conjur policies for entitlements and policy management
  D. the services that Conjur offers and typically refers to the list of configured and enabled authenticators in Conjur
  B. the services that Conjur offers and typically refers to a group of application identities in Conjur

  ---

  Explanation/Reference:

  Line of business (LOB) is a term used by CyberArk Secrets Manager to describe the services that Conjur offers and typically refers to a group of application identities in Conjur. A LOB can be defined by a Conjur policy that grants permissions and access to secrets for a specific set of applications. For example, a LOB can represent a business unit, a project, a product, or a team within an organization. A LOB can also have sub-LOBs that inherit the permissions and secrets from the parent LOB, but can also have their own specific policies and secrets. A LOB can help organize and manage secrets for different applications in a hierarchical and scalable way.

• Question 40:

  You start up a Follower and try to connect to it with a REST call using the server certificate, but you get an SSL connection refused error.

  What could be the problem and how should you fix it?

  A. The certificate does not contain the Follower hostname as a Subject Alternative Name (SAN). Generate a new certificate for the Follower.
  B. One of the PostgreSQL ports (5432. 1999) is blocked by the firewall Open those ports.
  C. Port 443 is blocked; open that port.
  D. The certificate is unnecessary. Use the command option to suppress SSL certificate checking.
  A. The certificate does not contain the Follower hostname as a Subject Alternative Name (SAN). Generate a new certificate for the Follower.

  ---

  Explanation/Reference:

  The correct answer is A. The certificate does not contain the Follower hostname as a Subject Alternative Name (SAN). Generate a new certificate for the Follower. A possible explanation is: A Follower is a read-only node that replicates data from the Leader node in a Secrets Manager cluster. A Follower can serve requests from clients and applications that need to retrieve secrets or perform other read-only operations. To connect to a Follower with a REST call, the client or application needs to use the server certificate that was generated for the Follower during the installation process. The server certificate is used to establish a secure and trusted connection between the client or application and the Follower. However, if the server certificate does not contain the Follower hostname as a Subject Alternative Name (SAN), the connection will fail with an SSL connection refused error. This is because the SAN is an extension of the X.509 certificate standard that allows the certificate to specify multiple hostnames or IP addresses that the certificate is valid for. If the Follower hostname is not included in the SAN, the client or application will not be able to verify the identity of the Follower, and will reject the connection. To fix this problem, a new server certificate needs to be generated for the Follower, with the Follower hostname added to the SAN. The new certificate can be generated using the openssl command or another tool that supports the SAN extension. The new certificate also needs to be signed by the same certificate authority (CA) that signed the original certificate, and the CA certificate needs to be trusted by the client or application. The new certificate then needs to be copied to the Follower node and configured in the nginx.conf file. The Follower node also needs to be restarted for the changes to take effect.
