    Ticket 13: Since the IP address of the HSRP gateway is within the range, shouldn’t be excluded as well?

    March 14th the big event, which started, is located one-block west of Welch and Mulberry Avenues.
    A custom truck is not set off by anything like a fantastic hunting pair
    of custom wheels. It’s the most recent drivers and woods in 2011.

    How can I determine the fault is in R4 ?

    The materials are very accurate. Few incorrect answers. But I do not expect a full score, anyway. 91% is enough for me. I just passed my CCNP Routing and Switching 300-135 exam 10 hours ago. The dumps are trustful. I recommend http://www.grades4sure.com/300-135-exam-questions.html to all who want to pass their exam in the first attempt. Practice your exam with this dumps and you will 100% pass your exam.

    I see tickets 2,10 and 13 removed from the premium site. Should we expect those 3 tickets on the real Exam, or not? Can someone please share your thoughts if you saw those 3 tickets on the Exam. Thanks

    @roller99: This ticket is up-to-date. Only the flash simulators are not. But we are working on it now so please wait for some time.

    @roller99 step back. you’re making demands from a site with the real answers you only paid $10 for (instead of 100+) and are doing the best they can. who waited until their certs are almost expired? Check your manners bro and check whose fault it is.

    So R4 is the DHCP server and the ip helper address can be any address on the device in this case loopback 1 :″ but in theory you could have used correct? I was able to figure out the problem.

    Not an easy one to spot since the client does have an address from DHCP even though DHCP is broken.

    exactly, i dont know if its the sim thats broken as it shouldn’t be so no?. the clients actually have addresses from dhcp range

    @roy: It is a bug in the exam so please don’t believe in the static IP addresses of the client.

    Hey Networktut when do you plan to update simulator
    Configuration on DSW1:

    interface Vlan 10
    ip address
    ip helper-address

    it will be great , helpful if done sooner

    A BUG IN THE EXAM!?!?!?


  25. Dzo
    July 13th, 2017

    Just wonder whether it’s a bug just coincidence. DSW1 doesn’t have a route to ip helper address, so it uses a default route pointing to… which is R4 anyway. As a result, the DHCP request reaches DHCP server hence IP address can be assigned to client.

    How many M/C questions on the exam?

  27. Shiko

    Where is the dhcp helper address.. I dont see it in the question or in the topology.

  28. ??

    Why does ASW1 have port security configured?

  29. Peter
    August 2nd, 2017

    @networktut and @roy, the client 1 & 2 have static ip, but if have any faults in ticket, client 1 & 2 don’t respond ping itself for ip address even they have static ip assigned. Did you get my point? I face this problem today in my exam. This ticket is valid. My score was 1000 today.

    August 12th, 2017

    Can anyone explain why helper address is ?

    It must be dhcp server address which is isnt it ?

    interface Vlan 10
    ip address
    ip helper-address


  31. YouKnowWho

    R4 is the DHCP server and the ip helper address can be any address on the device, in this case, interface lo1 :

    Since a loopback encounters less errors than an actual physical interface, this would be the safe bet. Of course, your network would have to advertise the loopback so it can get to it.

    Is this still valid?? Shouldnt it the fault be on R4??
