Refer to the exhibit. What can be concluded about network 192.168.4.0 in the R2 routing table?

8
An ABR in a multiarea OSPF network receives LSAs from its neighbor that identify the neighbor as an ASBR with learned external networks from the Internet. Which LSA type would the ABR send to other areas to identify the ASBR, so that internal traffic that is destined for the Internet will be sent through the ASBR?

9
Which three steps in the design and implementation of a multiarea OSPF network are considered planning steps? (Choose three.)
