Correct answer & explanation

10 seconds

OSPF uses different hello intervals depending on the network type. On broadcast and point-to-point networks (like Ethernet), the default hello interval is 10 seconds.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • 10 seconds

    Why this is correct

    This is the standard default for Ethernet and other broadcast networks.

  • 30 seconds

    Why it's wrong here

    30 seconds is the default for NBMA networks, not Ethernet.

  • 40 seconds

    Why it's wrong here

    40 seconds is not a standard OSPF hello interval.

  • 5 seconds

    Why it's wrong here

    5 seconds is used for some point-to-point links but not the default for Ethernet.

RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
