CyberArk SECRET-SEN Dumps Questions Answers

 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.

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.

ServiceAccount and StatefulSet are two of the Kubernetes resources/objects that can be used as Conjur identities, in addition to Namespace and Deployment. Conjur identities are the entities that can authenticate with Conjur and retrieve secrets from it. Conjur supports authenticating Kubernetes resources/objects using the Conjur Kubernetes Authenticator, which is a sidecar or init container that runs alongside the application container and injects the Conjur access token into a shared volume. The application container can then use the access token to fetch secrets from Conjur.

A ServiceAccount is a Kubernetes resource that represents an identity for processes that run in a pod. ServiceAccounts can be used to grant specific privileges and permissions to the pod, and to enable communication with the Kubernetes API server. A ServiceAccount can be used as a Conjur identity by annotating it with the Conjur authentication policy branch ID, and by creating a Conjur host entity that matches the ServiceAccount name and namespace. The Conjur Kubernetes Authenticator will then use the ServiceAccount token to authenticate the pod with Conjur and obtain the Conjur access token.

A StatefulSet is a Kubernetes resource that manages the deployment and scaling of a set of pods, and provides guarantees about the ordering and uniqueness of these pods. StatefulSets are useful for applications that require stable and persistent identities, such as databases, message brokers, or distributed systems. A StatefulSet can be used as a Conjur identity by annotating it with the Conjur authentication policy branch ID, and by creating a Conjur host entity that matches the StatefulSet name and namespace. The Conjur Kubernetes Authenticator will then use the pod name and namespace to authenticate the pod with Conjur and obtain the Conjur access token.

The other options are not valid Kubernetes resources/objects that can be used as Conjur identities. Replica sets are a lower-level resource that are usually managed by higher-level resources such as Deployments or StatefulSets, and do not have their own identity or annotations. Secrets are a Kubernetes resource that store sensitive information such as passwords, tokens, or keys, and are not meant to be used as identities. Tokenreviews are a Kubernetes resource that are used to verify the validity of a ServiceAccount token, and are not meant to be used as identities either. References:
