View the exhibit.

Part of an OSPF routing table in an HP 5800 switch is shown in the exhibit. This switch is an
internal switch in area 1. The network administrator views this routing table, and then reconfigures
area 1 as a stub area on all relevant switches. No other changes to the OSPF domain are made.
After this change takes effect, which routes shown in the exhibit will still exist in the OSPF routing
table of this switch?

A.
All of the routes will still exist.

B.
Only the routes to 10.1.1.0/30, 10.1.10.0/24, and 10.2.30.0/24 will still exist.

C.
Only the routes to 10.1.1.0/30, 10.1.10.0/24, and 172.16.0.0/16 will still exist.

D.
Only the routes to 10.1.1.0/30 and 10.1.10.0/24 will still exist.

E.
Only the route to 10.1.10.0/24 will still exist.

Explanation:
The internal routes will remain (10.1.1.0/30, 10.1.10.0/24, and 10.2.30.0/24).
Only the external route (172.16.0.0/16) will be removed.
Note: When an area is defined as stub, external routes will not be advertised into the area.
