H12-841_V1.5 · Question #235
When OSPF is deployed on a wide area network (such as an inter-carrier link), which of the following configurations can improve the adaptability and stability of the OSPF network? (Multiple choice)
The correct answer is A. Adjust OSPF hello/dead times (e.g., change the hello time to 30 seconds to adapt to high latency B. Enable OSPF authentication (such as zone authentication to prevent fake LSA injection). C. Divide OSPF into reasonable areas (e.g., divide cross-regional links into backbone areas Area 0). See the full explanation below for the reasoning.

Options
- AAdjust OSPF hello/dead times (e.g., change the hello time to 30 seconds to adapt to high latency
- BEnable OSPF authentication (such as zone authentication to prevent fake LSA injection).
- CDivide OSPF into reasonable areas (e.g., divide cross-regional links into backbone areas Area 0).
- DUsing the default hello/dead times (10s/40s) is not suitable for wide area network latency.
- EWithout configuring OSPF authentication, any device can access the OSPF domain .
