H12-821_V1.0 · Question #686
Which of the following descriptions of OSPF's own anti-environment measures are correct? (Multiple choice)
The correct answer is B. When OSPF divides areas, it stipulates that all non-backbone areas must be directly connected to the backbone area, and communications between non-backbone areas must be forwarded by the backbone area. E. Routers in the same area calculate a loop-free shortest path tree with itself as the root based on LSDB. See the full explanation below for the reasoning.
Question
Which of the following descriptions of OSPF's own anti-environment measures are correct? (Multiple choice)
Options
- AASBR is not allowed to exist in the OSPF backbone area
- BWhen OSPF divides areas, it stipulates that all non-backbone areas must be directly connected to the backbone area, and communications between non-backbone areas must be forwarded by the backbone area.
- COSPF's LSA flooding has a maximum of 16 hops. If it exceeds 16 hops, the LSA will be discarded.
- DOnly one ABR is allowed between the OSPF backbone area and the non-backbone area.
- ERouters in the same area calculate a loop-free shortest path tree with itself as the root based on LSDB.
