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.

Visual reference

R1 R2 R3 R4 10 100 10 100 OSPF picks R1→R2→R4 (cost 20) over R1→R3→R4 (cost 200)
