News inserita il 14/10/2008

Certificazione Cisco CCNAVuoi ottenere la Certificazione Cisco CCNA? Vuoi sapere quali argomenti ti verranno richiesti durante l'esame di Certificazione Cisco Certified Network Associate (640-802, CCNA)?
Per ottenere la Certificazione Cisco CCNA è necessario superare l'esame Cisco Certified Network Associate (640-802, CCNA), oppure entrambi gli esami Interconnecting Cisco Networking Devices Part 1 Exam (640-822, ICND1) e Interconnecting Cisco Networking Devices Part 2 Exam (640-816, ICND2).

Scadenza e rinnovo della Certificazione Cisco CCNA

La Certificazione Cisco CCNA è valida tre (3) anni. Per rinnovarla è necessario sostenere uno dei seguenti esami:
  • l'esame Interconnecting Cisco Networking Devices Part 2 (640-816, ICND2)
  • l'esame Cisco Certified Network Associate Exam (640-802, CCNA)
  • uno dei tre esami CCNA Concentration (wireless, security o voice)
  • l'esame Designing for Cisco Internetwork Solutions (640-863 DESGN)
  • un qualsiasi esame del livello Professional (642-xxx)
  • un qualsiasi esame del livello Specialist (escluso quello Sales Specialist
  • l'esame scritto CCIE o CCDE

Descrizione della Certificazione Cisco CCNA

Il 640-802 Cisco Certified Network Associate Exam (CCNA) è l'esame composito associato alla Certificazione Cisco Certified Network Associate (CCNA). Ciò significa che esiste perfetta equivalenza tra sostenere l'esame 640-802 oppure i due singoli esami Interconnecting Cisco Networking Devices Part 1 (640-822, ICND1) e Interconnecting Cisco Networking Devices Part 2 (640-816, ICND2).
I candidati all'esame di Certificazione Cisco Certified Network Associate (640-802, CCNA) si possono preparare seguendo il:
