ey lui, dit zijn dus de correcte antwoorden van CCNA semester 1 !!!

Dit zijn de antwoorden van VERSIE 3.1.1
( niet van versie 3.1, surf voor de antwoorden van versie 3.1 naar http://netacad.wz.cz/ )

op www.testanswers.info staat ook wel wat leuks bij trouwens

HET ENIGE NADEEL is, per toets staan ze in een andere volgorde...
dus leer de antwoorden uit je hoofd vantevoren!!!

Dit is vooral bedoeld voor de mensen die het even moeilijk hebben met de toetsen en hoge resultaten nodig hebben.



Ok, even opletten. Deze antwoorden komen van verschillende "bronnen",


( cisco is momenteel nogal op zoek naar sites die antwoorden geven, dus dit is een van de weinigen die overgebleven zijn/blijven)


nog even een tip, tis nogal wat tekst!! om snel toets te vinden zoek dan makkelijk en gebruik toetscombinatie "CTRL + F" en typ dan "chapter test "nummer van je module"


Mocht er iets niet kloppen of iets dergelijks lama bericht 8er dan, en als het heeft geholpen lama weten met een bericht dan, altijd fijn om andere te helpen he;)

20


Refer to the exhibit. A network administrator is planning the addressing scheme
for the LAN using 172.25.14.0/26. The hosts are to be assigned addresses
172.25.14.1 – 172.25.14.25. The LAN interface of the router is to be
configured using 172.25.14.63 as the IP address. What would describe this addressing scheme?

The LAN is being addressed properly.

The subnet that is being assigned is not a usable subnet address.

The router LAN interface is being assigned a broadcast address.**

The subnet mask does not allow enough host addresses in a single subnet.



21

PC1 and PC2

all servers**

only PC2 Laptop

all hosts and all servers



22

24


Refer to the exhibit. A newly hired technician is testing the connectivity of all hosts
by issuing a ping command. The technician notices that a default gateway is
not configured on all the hosts, but all hosts have connectivity between hosts,
a fact which seems to confuse the technician. How would you explain the
connectivity to the technician?

The hosts are detecting the default gateway configured on the hub.

The hosts are all in one LAN, so default gateway information is not needed.**

The hosts in the network only require that one host has a gateway configured.

The hosts in the network would only need a gateway if a switch replaces the hub.

The hosts are using broadcast to reach each other since no gateway is configured.



25


Refer to the exhibit. Based on the information shown, which two statements are true? (Choose two.)

An ARP request must be used to obtain an address that is placed in the ARP table.

Frames from other hosts in the network to this host will use a destination
address of 00-06-25-25-6e-5d.

The only remote locations that can be reached from this host are
192.168.1.97 and 192.168.1.254.

If a packet is sent to a network device other than 192.168.1.97
and 192.168.1.254, an ARP request must be used.**

If the computer with the IP address of 192.168.1.94 sends a
packet to the device with the IP address 192.168.1.97, no ARP request is required. ***
