salut je me prepare actuellement pour le ccna.

Lu marcelo_01,

Je te propose que tu nous indiques tes réponses et nous te les corrigerons.

VTP is only compatible with the 802.1Q standard.
VTP adds to the complexity of managing a switched network.

RIP v2 must be configured with the network command and the IP host address and subnet mask for the newly activated interface.
The router must be configured with the ip subnet-zero command so that this network can be added and advertised.
A network host address and subnet mask must be applied to the newly activated interface.
The routing protocol must be activated with the router rip and version 2 commands.

Periodic updates are sent every 120 seconds to neighboring routers.
Each router sends its entire routing table to neighboring routers.
*Routers send updates when a change in the network is detected.
*Link-state protocols converge more rapidly than distance vector protocols.
After convergence, link-state protocols use more bandwidth than distance vector protocols use.
*Link-state protocols are less prone to routing loops than distance vector protocols.

bonjour
c ma première participation à ce forum.
j ai visité le lien vers les exams des 4 semestres . a la fin y avait un lien vers practice et un autre vers practice final.
http://www.frameip.com/examen-cisco/
quelle est la difference entre ces deux derniers.
a savoir que je suis entrain de chercher le voucher (qui donne droit à une reduction sur l'examen indistruel)
est ce l'examen indistruel est une autre nommination de practice final!
merci
Bonjour,
vous permettez ? 🙂

merci bien,
j'ai eu 70% sur ce test il ya maintenant une periode.
maintenant je suis entrain de faire le 4éme test final.
alors si qq1 peut nous donner les solutions

merci
Lu HAMZATN,

Peux tu nous indiquer les 30% afin que l'on en discute ?

Pour le 4 ème semestre, je te propose que tu ouvres un nouveau POST et que tu réponde aux questions. Et après on t'aide dans la correction 🙂

Salut HAMZATN.

Tu parles de questionnaires en ligne Netacad ?

Car si tu te bases et t'entraines que là dessus avec 70% de réussite, tu risques d'être bien surpris au vrai CCNA. 😕
Bonjour Tlm ;

Dites svp , est ce qu'il y a possibilité de passer la certif Cisco en ligne ?

Merci D'avance
