Virtual Private Network and Remote Access Questions

Understanding virtual private network technology and secure remote access patterns. Candidates should be able to explain how virtual private networks create encrypted tunnels between remote clients and internal networks, authentication and authorization options including certificate based authentication and multi factor authentication, transport and encryption tradeoffs, split tunneling and its operational risks, deployment and scaling of gateway and client solutions, bastion host and jump server patterns for privileged access, management of client configuration and credentials at scale, and logging and monitoring of remote sessions. Interview assessments often probe access revocation processes, certificate rotation, and integration with single sign on providers.
