Which three benefits are made possible by the separation of the control plane and forwarding plane of a Junos device? (Choose three.)
Which three benefits are made possible by the separation of the control plane and forwarding plane of a Junos device? (Choose three.)
The separation of the control plane and forwarding plane in a Junos device allows for in-service software upgrades which enable upgrades to be performed without disrupting existing services. It also enables graceful Routing Engine switchover, ensuring continuous operation by allowing the backup Routing Engine to take over without impacting network service during a failure or manual switchover. Additionally, nonstop active routing ensures protocol sessions and routing tables are fully synchronized between Routing Engines to avoid disruptions. Together, these features provide high availability and minimal service interruption.
Unified ISSU ( In-Service Software Upgrade) - Enables upgrades between two different versions of Junos OS without service interruption on the control plane - Eliminates network downtime during software image upgrades - Reduces operating costs while delivering higher service levels - Enables rapid implementation of new features. Unified In-Service Software Upgrade (Unified ISSU) lets you upgrade from one version to another of Junos OS without any disruption to the control plane, and with minimal disruption to traffic. Unified ISSU is only supported on the dual Routing Engine platform. In addition, GRES (Grieful Routing Engine switchover) and NSR (Non-Stop Active Routing) functions must be enabled.
i think thats correct
"This architectural design also makes possible the incorporation of high availability features like graceful Routing Engine switchover (GRES), nonstop active routing (NSR), and unified in-service software upgrades (ISSUs)." https://douran.academy/wp-content/uploads/ebooks/jnica-junos-study-guide-part1.pdf Page nr. 8
