A.
R4(config)# ip route 0.0.0.0 0.0.0.0 10.1.1.1

B.
R4(config)# ip default-network 10.0.0.0

C.
R4(config-router)# default-information originate

D.
R4(config)# ip route 10.0.0.0 255.0.0.0 10.1.1.1

Explanation:
Unlike the ip default-gateway command, you can use ip default-network when ip routing is
enabled on the Cisco router. When you configure ip default-network the router considers
routes to that network for installation as the gateway of last resort on the router.
For every network configured with ip default-network, if a router has a route to that network,
that route is flagged as a candidate default route.
Gateways of last resort selected using the ip default-network command are propagated
differently depending on which routing protocol is propagating the default route. For IGRP
and EIGRP to propagate the route, the network specified by the ip default-network command
must be known to IGRP or EIGRP. This means the network must be an IGRP- or EIGRPderived network in the routing table, or the static route used to generate the route to the
network must be redistributed into IGRP or EIGRP, or advertised into these protocols using
the network command. In this case, the 10.0.0.0 network is indeed being advertised via EIGRP.

    300-101 was Not this material
    I did all 653 questions 3 times each and drilled

    Scored 709/1000 on conceptual understanding but was aware how far it has changed this year

    Study
    Acl
    Snmpv3 detail a syntax grind
    PPPoE extensively
    eVN trunks and tunnel details

    Ip helper-address (syntax grind)
    Ntp
    Ndp
    IPv6 eui-64 and tunneling
    And I saw a lot about IPSec and DMVPN

    And all the BSCI sim are included
    I had 7 sim but no drag drop

    THE ABOVE POST IS 100% CORRECT. THIS IS NOT THE EXAM AT ALL!!!

    Took the exam today and failed. I studied all 654 questions. Went over them 7 times and memorized every single one of them. The exam had 50 questions and required a 790 to pass.

    NOT A SINGLE ONE OF THESE QUESTIONS WAS ON THAT EXAM!

    This are all good questions to study for the exam, but YOU WILL NOT see a single one of these questions on your actual exam. Please update these questions.

    I failed the Cisco IP Routing exam after I used some free study guides found online. I was lucky enough to find cisexams and preparing with their study Material helped me clear my Pass4sure 300-101 exam with a very high score.

      How exactly did you do that when Cisexams only has the really old 640-XX cisco exams that are no longer valid, and Pass4sure doesn’t offer anything for this exam???

    I don’t think this is correct. R4 should have the classfull A network ( 10.0.0.0/8 ) in the routing table first and It doesn’t. If we leave out “no auto-summary” then that would be true.
