HSRP Questions 3

November 15th, 2018 in SWITCH 300-115 Go to comments

Question 1

Explanation

The last two-digit hex value in the MAC address presents the HSRP group number.

Question 2

Explanation

Answer A and B are correct because they are the functions of HSRP. I just want to mention about answer D. In fact answer D is not totally correct, in SWITCH only GLBP has the load-balancing feature. HSRP can only load-sharing by configuring some different HSRP groups. But answer D is the only choice left in this question so we have to choose it.

Question 3

Question 4

Question 5

Question 6

Question 7

Question 8

Question 9

Question 10

    What about Q2 and answer C? CCNP Official Cert Guide says: “The routers exchange HSRP hello messages at regular intervals so that they can remain aware of each other’s existence and that of the active router.” Besides, we can see an example of packets exchange in Q9 of “HSRP Questions”. Therefore, all routers can assume current state of each other. So, I guess, answer C may be correct instead answer D.

    @Certprepare please share the link for questions. I would also like to bring into your knowledge that some questions and exhibits are missing but they are explained on certprepare. com

    @Certprepare please share latest link for the questions.

    Q6. Would be good to have an explanation here as ‘A’ doesn’t seem to fit in with ‘B’ and ‘C’ to my way of thinking.

    CISCO really need to fix there questions
    Question 5
    it clearly said in the RFC the State

    Listen

    The router knows the virtual IP address, but is neither the active
    router nor the standby router. It listens for Hello messages from
    those routers.

    4. Speak

    The router sends periodic Hello messages and is actively
    participating in the election of the active and/or standby router.
    A router cannot enter Speak state unless it has the virtual IP
    address.

    there is no correct answer ,,,,,so we chose Listen
    Bullshit

    q6
    • HSRP is designed for use over multiaccess, multicast, or broadcast capable Ethernet LANs. HSRP is not intended as a replacement for existing dynamic protocols.

    Q7
    HSRP is configurable on Ethernet, FDDI, BVI, LANE, or Token Ring interfaces. Token Ring
    interfaces allow up to three Hot Standby groups each, the group numbers being 0, 1, and 2.

    Q.2 D surely is correct simply because we can play with HSRP groups (mHRSP) to provide the load balancing, by configuring a set of half of hosts with default gateway Virtual IP of a groupe and the other half if hosts default gateway which is the virtual IP of the other group

    Q.8 D is correct because there is preemption enabled and the delay is 5 seconds.

  12. HSRP Standby

    Q5
    I think the question maybe a little bit miss worded but I think the answer B is correct. if it applies to the following:

    “In order to minimize network traffic, only the active and the standby routers send periodic HSRP messages after the protocol has completed the election process. Additional routers in the HSRP group remain in the Listen state. If the active router fails, the standby router takes over as the active router. If the standby router fails or becomes the active router, another router is elected as the standby router.”

    Q10
    arent there informations missiing about the routers ? like Priority or preempt ?

    Q.8, HSRP preempt is not enabled by default, a device can not become active if preempt is not explicitly configured.
    I would go for B, because preempt is enabled on the local device

    Q8, I test out on Packet Tracer, D is true. The answer should be C D.

  16. Q8
    July 28th, 2019

    This seems right…

    B. If the local device fails to receive a hello from the active router for more than 5 seconds, it can become the active router.

    I’m confused with Q8.

    Why is D correct?
    What router are they referring to? How are we supposed to determine there is a 3rd router with Pre-empt configured (disabled by default) with a 5 sec delay.

    B is correct based on the information given.

    @Q8
    @sasuke

    Preemption enable, delay 5 this means that if active router fails standby router will preempt after 5 seconds

    What you are thinking here is the hello and hold timer, standby router will preempt if the hello and hold timer is not receive/expires from active router. Causes for this not to receive is if the active router fails or active interface from where the hsrp configure is down

    Sorry, should the Q10 have an exhibit or some config?

    I think Q2 has more than 4 variants…

    Q3 and Q9 are the same…

    Q5 is in two parts. First you need to correctly identify what FHRP it is. This should be GLBP since it mentions Virtual Gateway! The link below mentions Disabled, Initial, Listen, Speak, Standby and Active. That rules out A and D, leaving B and C. We know it obviously can’t be Initial, so we are left with C (Listen).

    Unfortunately, if we were to assume that the question is correct, then even “Listen” isn’t the correct answer. So I suspect the question isn’t completely correct.

    Q6 and Q7: Since certprepare didn’t provide any explanation to backup their answer, I thought I should help out. Below is the extract and the respective link:

    • HSRP is designed for use over multiaccess, multicast, or broadcast capable Ethernet LANs. HSRP is not intended as a replacement for existing dynamic protocols.
    • HSRP is configurable on Ethernet, FDDI, BVI, LANE, or Token Ring interfaces. Token Ring
    interfaces allow up to three Hot Standby groups each, the group numbers being 0, 1, and 2.

    Q6 and 17 seems conflict.
    If talking ring not supported so how it has group numbers?

    Q8
    im for A and C
    A. The hello and hold timers are set to custom values.
    in exhibit timers hello 3 sec hold 10 sec, it is default hsrp timers

    about D.
    D. If the router with a higher IP address and same HSRP priority as the active router becomes available, that router becomes the new active router 5 seconds later.
    It is try but only if preemption configured too, but there no info about it.

    HSRP Priority and Preemption
    If you do not use the “standby preempt” interface configuration command in the configuration for a router, that router will not become the active router, even if its priority is higher than all other routers.A standby router with equal priority but a higher IP address will not preempt the active router.

    Good call @Tom. Without preemption “standby preempt” command, no coup will happen.

  27. Dmytro
    October 9th, 2019

    Q8 right answers are:
    A. The hello and hold timers are set to custom values.
    C. The virtual IP address of the HSRP group is 10.1.1.1.

    Variant “D. If the router with a higher IP address and same HSRP priority as the active router becomes available, that router becomes the new active router 5 seconds later.” isn’t right because preempt and delay are configured for this router and it is already in the active state, and we don’t know about configuration (preempt and delay) of new router with a higher IP address.
