Which are the two advantages of Cisco IOS XR Software over Cisco IOS Software? (Choose two.)
Click on the arrows to vote for the correct answerA. B. C. D. E.
A monolithic OS: Cisco IOS XR Software is a monolithic operating system that uses a microkernel architecture. This means that the OS runs as a single process, providing enhanced stability and reliability. In contrast, Cisco IOS Software is modular and composed of multiple processes that interact with each other. This can result in a higher risk of instability, especially when making changes or upgrades to the system.
Two-stage configuration: Cisco IOS XR Software uses a two-stage configuration process that separates the configuration of the system from the activation of the configuration. This provides a high degree of control over the configuration process and minimizes the risk of configuration errors. In contrast, Cisco IOS Software uses a one-stage configuration process, which can be more error-prone, as configuration changes are activated immediately upon entry.
