JN0-102 · Question #122

Referring to the exhibit, which three networks match the policy? (Choose three.) [edit policy-options policy-statement my-policy] user@router# show term 1 { from { route-filter 192.168.0.0/16…

The correct answer is A. 192.168.0.0/16 C. 192.168.65.0/24 E. 192.168.24.89/32. The policy term uses route-filter 192.168.0.0/16 orlonger, which matches the exact prefix 192.168.0.0/16 and any more specific (longer) prefixes that fall within this /16 range.

Why each option

The policy term uses `route-filter 192.168.0.0/16 orlonger`, which matches the exact prefix 192.168.0.0/16 and any more specific (longer) prefixes that fall within this /16 range.

A192.168.0.0/16Correct

`192.168.0.0/16` exactly matches the base prefix `192.168.0.0/16` and is explicitly included by the `orlonger` match type.

B192.168.0.0/15

`192.168.0.0/15` is a *shorter* (less specific) prefix than `192.168.0.0/16`, so it does not match `orlonger`.

C192.168.65.0/24Correct

`192.168.65.0/24` is a more specific prefix (length /24 is longer than /16) that falls within the `192.168.0.0/16` range, so it is matched by `orlonger`.

D192.167.0.0/17

`192.167.0.0/17` does not fall within the `192.168.0.0/16` range; its network address is outside the specified /16 prefix.

E192.168.24.89/32Correct

`192.168.24.89/32` is a host route (a very specific, longer prefix length /32 > /16) and falls within the `192.168.0.0/16` range, so it is matched by `orlonger`.
