Dumps4Cert 2018 PDF and VCE

  1. Dual Stack

  2. NAT-PT

  3. 6to4 tunnel

Question No: 232 – (Topic 7)

When an IPv6 enabled host boots, it sends a router solicitation (RS) message. An IPv6 router responds with a router advertisement (RA). Which two items are contained in the RA?

(Choose two.)

  1. IPv6 address for the host

  2. lifetime of the prefix

  3. prefixes for the link

  4. keepalive timers

  5. request for the local host IP address

  6. any route advertisements it has received

Answer: B,C Explanation:

In IP Version 6, Router Advertisements have the following attributes:

  • Routers advertise periodically

    • Max. time between advertisements can be in the range from 4 and 1800 seconds

    • The advertisement has a lifetime (= 0 if not a default router)

  • Advertisement contains one or more prefixes

    • Prefixes have a lifetime

  • Preferred lifetime

  • Valid lifetime

  • Specifies if stateful or stateless autoconfiguration is to be used

  • Plays a key role in site renumbering

    A network engineer receives a command output from a customer that indicates an issue with NTP. What are two reasons for the output? (choose two)

    1. NTP traffic is blocked.

    2. NTP is not configured.

    3. The router is the NTP master.

    4. ntp update-calendar is missing.

    5. There is an NTP authentication failure.

    Answer: A,E

    Explanation: NTP uses a value, called a stratum value , to indicate the believability of a time source.

    Valid stratum values are in the range 0-15, with a value of 16 being used to indicate that a device does not have its time synchronized. However, Cisco IOS only permits you to

    set stratum values in the range 1-15.

    1. solicit

    2. advertise

    3. request

    4. auth

    5. reply

    What is the correct configuration to enable router P4 to exchange RIP routing updates with router P1 but not with router P3?

    1. P4(Config)# interface fa0/0P4(Config-if)# neighbor passive- interface fa0/0

    2. P4(config)# router ripP4(config-router)#neighbor router)#passive-interface fa0/0

    3. P4(config)# interface fa0/0P4(config-if)# neighbor passive interface192.168.10.34

    4. P4(config)# router ripP4(config-router)# neighbor no broadcastP4(config- router)# passive-interface fa0/0

    Answer: B Explanation:

    When you configure router P1 to be the nieghtobr of P4 with a passive interface, the RIP routing updates will be exchanged with the neighbor only.

    Question No: 236 – (Topic 7)

    1. Specific addresses cannot be selected for importation into the OSPF process.

    2. Specific addresses can be selected using an ACL.

    3. Specific addresses can be selected using a route map.
