Which two statements about the behavior of the device are true?

Refer to the exhibit. If this configuration is applied to a device that redistributes EIGRP routes into OSPF. which two statements about the behavior of the device are true? (Choose two )

A. EIGRP routes appears in the routing table as E2 OSPF routes
B. The device router ID is set to Loopback0 automatically
C. The device redistributes all EIGRP networks into OSPF
D. EIGRP routes appears in the routing table as N2 OSPF routes
E. The device redistributes only classful EIGRP networks into OSPF.
F. EIGRP routes appears as type 3 LSAs in the OSPF database.

  1. C and E contradicts, they can be both correct.
    C says; The device redistributes all EIGRP networks into OSPF, this means classless and classful networks
    but
    E says The device redistributes only classful EIGRP networks into OSPF., not classful,

    if E is correct (im sure its correct) then C can never be correct.

  2. Following up on my first post. Proof.

  3. C and E are correct.
    Carefully read the question.
    “Refer to the exhibit. If this configuration is **applied to a device** that redistributes EIGRP routes into OSPF. which two statements **about the behavior of the device** are true?”
    The question asks, if this configuration is applied to Device A, what is true about the Behavior of Device A?
    It’s not asking about the behavior of down-stream Router B.
    As such, A is incorrect as the redistributed routes do not show up as E2 on Device A where the redistribution occurred.

  4. (config)#router ospf 1
    (config-router)#redistribute eigrp 1
    % Only classful networks will be redistributed
    —> E. The device redistributes only classful EIGRP networks into OSPF.
    and
    A. EIGRP routes appears in the routing table as E2 OSPF routes
    are correct

  5. I don’t agree with E that could be correct since the EIGRP network redistributed into OSPF is “10.0.0.0 0.0.0.255”, which is not a natural class A network (just 10.0.0.0 itself), but with a wildcard to specify a smaller network. So I think item C that should be better than E

    1. No, by default redistribute eigrp only redistributes routes in classful boundaries. To redistribute also the subnets, you need to add “subnets” keyword.

  6. Another blind copy from digitaltut…

    A and E seems most correct here, like commented by hn and Jay.

    Be mindful about answer A, because it will not count on the routing table of the ASBR itself from which we are seeing the configuration snip!

  7. Another badly worded Cisco question. E is definitely correct but A is confusing as routes only appear as O E2 on the next router in the link, not on the ASBR. I think I would choose A over C, as C directly contradicts E.

    1. Agree, they’re probably not talking about the ASBR routing tabke, but it is very obvious that E is correct and C is almost always incorrect unless every route inside EIGRP is classful.

      I would definitely go with A and E, even though your point is correct.
