A. B. C. D.A
The correct answer is A. Each process has its own protected memory space.
In the Junos OS, multiple software processes are used to manage different functions such as routing, forwarding, and management. Each process has its own unique memory space, which provides the following advantages:
Isolation: By running each process in its own protected memory space, faults or crashes in one process do not affect the others. This improves system stability and reduces the risk of a single process bringing down the entire system.
Security: Each process can be assigned its own permissions and access controls. This means that even if one process is compromised, it cannot access or affect other processes, improving system security.
Scalability: By dividing tasks into multiple processes, the system can scale more easily. For example, if the routing process becomes too resource-intensive, it can be moved to a separate hardware component or even to a different system, without affecting the other processes.
B. Each process is started manually by the user at boot - This statement is incorrect. In Junos OS, processes are started automatically during system boot and are managed by the operating system.
C. All processes are dependent on each other - This statement is incorrect. Each process is designed to operate independently of other processes, improving system stability.
D. Multiple processes allow each routing protocol to be independent - This statement is partially correct. By running each routing protocol in a separate process, they can operate independently of each other, improving system stability and scalability. However, this is just one advantage of running multiple processes, and not the only advantage.
