+= Part 1: Answer Questions
+
+1. When ONOS activate "org.onosproject.openflow," what APPs does it activate?
+
+It activates:
+- org.onosproject.openflow
+- org.onosproject.hostprovider
+- org.onosproject.lldpprovider
+- org.onosproject.openflow-base
+- org.onosproject.optical-model
+
+2. After we activate ONOS and run P.17 Mininet command, will H1 ping H2 successfully? Why or why not?
+
+No, S1 and S2 will not forward packets unless `org.onosproject.fwd` is activated.
+
+3. Which TCP port does the controller listen to the OpenFlow connection request from the switch? (Take screenshot and explain your answer.)
+

+
+The ports that appeared only when openflow-base were enabled are:
+- tcpv6 `:::6633`
+- tcpv6 `:::6653`
+
+4. In question 3, which APP enables the controller to listen on the TCP port?
+
+`org.onosproject.openflow-base`
