Refer to the exhibit. A network engineer with an employee ID 4402:98:032 is setting up an IS-IS network with these requirements: - Routes with a tag of 80 and IP prefixes other than 192.168.10.20/24 m

Removing `match tag 40` from `route-map leak2-1` would prevent routes tagged 40 from being leaked from L2 to L1, which violates the requirement to leak routes tagged with 50 or 40.

Adding `match tag 80` to `route-map leak2-1` would leak routes tagged 80 from L2 to L1, which is not part of the specified L2 to L1 leaking requirements (tags 50 or 40).

Changing `match tag 80` to `match tag 50` in `route-map redist1-2` would prevent routes tagged 80 from being redistributed from L1 to L2, violating the first requirement.

The first requirement states that routes with a tag of 80 and IP prefixes other than 192.168.10.20/24 must be redistributed from Level 1 into Level 2 via route-map `redist1-2`. Adding `match ip address 152` to `redist1-2` allows the router to filter routes based on an access list (presumably 152), which would be configured to permit all IP prefixes except 192.168.10.20/24.
