NEW QUESTION # 75
Refer to the exhibit.
A network operator must inject a Level 1 route from XR2 (10.16.16.0/24) into the ISIS topology. Which configuration allows the injection in a way that XR3 and XR1 have a valid and working route for 10.16.16.0/24?
- A. Option D
- B. Option C
- C. Option B
- D. Option A
Answer: A
