FORTINET-NSE123 Practice Question: Nse 2 Technical Introduction TO Fortinet Security
When configuring dynamic routing on a FortiGate using OSPF, what is the purpose of defining OSPF areas?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
To divide routing domains hierarchically, reducing routing overhead and limiting link-state update traffic
OSPF areas divide large autonomous systems into smaller logical hierarchical segments to reduce routing table size, limit link-state update propagation, and optimize convergence.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To balance SSL VPN tunnel connections across multiple cluster nodes
Why it's wrong here
VPN session load balancing is handled by HA clusters or load balancers, not OSPF.
- ✗
To assign IP addresses dynamically to connected client workstations
Why it's wrong here
Dynamic IP assignment is handled by DHCP servers.
- ✗
To encrypt firewall policy rules between different physical interfaces
Why it's wrong here
Encryption of traffic is handled by IPsec VPNs, not OSPF routing areas.
- ✓
To divide routing domains hierarchically, reducing routing overhead and limiting link-state update traffic
Why this is correct
OSPF areas optimize routing scale by containing topology update traffic within areas.
