QUESTION 1

Refer to the exhibit. XR1 and XR2 are sending the prefix 10.11.11.0/24 to XR3. A configured policy on XR1 is incorrectly

the falsely prepending prefix from being installed.
Which policy configuration applied to the XR3 neighbor configuration for XR1 can accomplish this requirement without
impact to other or future received routes?

A. Option A
B. Option B
C. Option C
D. Option D

Correct Answer: D

configuration?
