contain a next-hop IP address*
contain subnets
be a classful network entry
be a default route

What is different between IPv6 routing table entries compared to IPv4 routing table entries?

By design IPv6 is classless so all routes are effectively level 1 ultimate routes.*
IPv6 does not use static routes to populate the routing table as used in IPv4.
IPv6 routing tables include local route entries which IPv4 routing tables do not.
The selection of IPv6 routes is based on the shortest matching prefix, unlike IPv4 route selection which is based on the longest matching prefix.

Which dynamic routing protocol was developed as an exterior gateway protocol to interconnect different Internet providers?


Which route will a router use to forward an IPv4 packet after examining its routing table for the best match with the destination address?

a level 1 ultimate route*

Which two statements describe the OSPF routing protocol? (Choose two.)

used primarily as an EGP

uses Dijkstra’s algorithm to build the SPF tree*

Which two events will trigger the sending of a link-state packet by a link-state routing protocol? (Choose two.)

the requirement to periodically flood link-state packets to all neighbors
a change in the topology*
the initial startup of the routing protocol process*
the router update timer expiring
a link to a neighbor router has become congested

Place the options in the following order:
[+] typically used on stub networks
[+] less routing overhead
[#] new networks are added automatically to the routing table
[#] best choice for large networks

[+] Order does not matter within this group.

[+] event-driven updates
[+] building a topological map
[+] fast convergence
[#] bandwidth consumption
[#] memory usage
[#] CPU processing time

[+] Order does not matter within this group.
[#] Order does not matter within this group.

Refer to the exhibit. A network administrator has issued the exhibited commands in an attempt to activate RIPng on interface gig0/0. What is causing the console message that is shown after RIP is enabled?

    Great work….

    U saved a lot of time for millions around the world especially for students who had to complete CCNA in a year.

    But in fact, we still need to understand the basic concepts of every topics in a chapter.

  • Naomi

    Thank you, your quizzes are a life saver. it saves a lot of time, by reading bits and pieces of topics instead of reading, hundreds of pages endlessly which become tiresome and difficult to remember

    En el contexto de los protocolos de routing, ¿cuál es la definición de “tiempo de convergencia”?

    *La cantidad de tiempo que tardan las tablas de routing en alcanzar un estado constante después de un cambio de topología.

    La cantidad de tiempo que necesita un administrador de red para configurar un protocolo de routing en una red de pequeña a mediana.

    La capacidad para transportar datos, video y voz por los mismos medios.

    Una medida de la complejidad de configuración del protocolo.

    Complete el espacio. No use abreviaturas.
    Al configurar RIPng, el c omando: default-information originate .ordena al router que propague una ruta predeterminada estática.
