Refer to the Exhibit.
In the exhibit, Area 1 and Area 2 are configured as not-so-stubby areas. RIP network 192.168.100.0/24 is redistributed into OSPF in Area 1.Which three statements are true? (Choose three.)
A.
Network 192.168.100.0/24 is advertised in a Type 7 LSA in Area 1.
B.
Network 192.168.100.0/24 is advertised in a Type 7 LSA in Area 0.
C.
Network 192.168.100.0/24 is advertised in a Type 5 LSA in Area 0.
D.
The area border router between Area 0 and Area 2 converts network 192.168.100.0/24 to a Type 7 LSA.
E.
Area 2 does not see the network 192.168.100.0/24 in its link-state database.

NSSAs
As noted previously, an OSPF stub area does not carry external routes, which
means you cannot redistribute routes into a stub area because redistributed routes
are always treated as AS externals in OSPF. An NSSA bends this rule and allows a
special form of external route within the NSSA. Although an NSSA can originate
AS externals into OSPF, external routes from other areas are still not permitted
within the NSSA. This is a case of having one’s cake (small LSDB due to not being
burdened by externals from other areas) while eating it, too (being allowed to bur-
den other routers with the external routes you choose to generate). The NSSA’s
ABRs can translate the special form of external route used in an NSSA for flooding
over the rest of the OSPF domain. NSSAs can be configured to receive only a default
route from the ABR, becoming a Totally Not So Stubby Area. Who said the stand-
ards bodies do not have a sense of humor?
