350-501 Architecture Practice Question
In IOS XR, each routing protocol runs as a separate process. What is the primary benefit of this architecture?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It allows each protocol to be upgraded independently without a system reboot.
Process separation provides fault isolation; a crash in one protocol process does not affect others, improving overall system stability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It simplifies configuration by combining all protocols into a single file.
Why it's wrong here
Configuration is not simplified by separate processes.
- ✓
It allows each protocol to be upgraded independently without a system reboot.
Why this is correct
Individual processes can be restarted or upgraded without affecting other processes.
- ✗
It reduces memory consumption by sharing code between processes.
Why it's wrong here
Separate processes may increase memory usage due to duplication.
- ✗
It improves forwarding performance by dedicating CPU cores to each protocol.
Why it's wrong here
Forwarding is typically hardware-based; process separation is about control plane stability.
