Which statement is true regarding the Junos OS?
Click on the arrows to vote for the correct answer
A. B. C. D.B
The correct answer is B. All platforms running the Junos OS separate the functions of control and forwarding.
The Junos OS is the operating system used by Juniper Networks on its networking equipment such as routers, switches, and security devices. The Junos OS architecture is based on a modular design that separates different functions of the operating system into discrete processes, allowing for more efficient and scalable operation.
Option A, "All platforms running the Junos OS separate the functions of learning and flooding," is not correct. Learning and flooding are functions of the data plane, which is responsible for forwarding packets between network devices. While the Junos OS does separate various functions of the data plane, such as forwarding and filtering, it does not separate learning and flooding.
Option C, "All platforms running the Junos OS separate the functions of routing and bridging," is also not correct. Routing and bridging are functions of the data plane, and while the Junos OS does separate various functions of the data plane, it does not separate routing and bridging.
Option D, "All platforms running the Junos OS separate the functions of management and routing," is also not correct. Management is a function of the control plane, which is responsible for managing and configuring the network devices. While the Junos OS does separate various functions of the control plane, such as routing and management, it does not separate management and routing.
Option B, "All platforms running the Junos OS separate the functions of control and forwarding," is correct. The Junos OS separates the control plane, which is responsible for managing and configuring the network devices, from the data plane, which is responsible for forwarding packets between network devices. This separation allows for greater scalability, performance, and flexibility in network design and operation.
