Экзамен 100 105 icnd1

Interconnecting Cisco Networking Devices Part 1 (ICND1 3.0)

Актуальность теста Cisco 100-105

Внимание — этот экзамен устарел. Обновлённый вариант — 200-301

Повторные попытки сдачи

• Кандидаты, которые неудачно сдали любой экзамен с кодом 35n-nnn (это Core-экзамены, которые сейчас вместо ранее существовавших 40n-nnn CCIE:Written), либо CCDE, могут повторно попытаться сдать тот же тест не ранее чем через 15 дней;
• Все остальные экзамены (CCNA и CCNP-уровней, коды 2nn-nnn и 30n-nnn) можно повторно пробовать сдавать через 5 дней;
• Особые люди, которые хотят пересдать уже сданный экзамен (такое редко, но необходимо; скажем человек стал инструктором CCSI, и чтобы преподавать курс X ему надо сдать экзамен по этому курсу на 935/1000 баллов — потому что у преподавателей Cisco другой уровень для успешной сдачи, выше, чем у всех остальных — и поэтому он, хоть и уже сдал экзамен, идёт и пересдаёт его на «инструкторский» проходной балл), могут сделать это через 180 дней после успешной попытки;

Сертификации

Экзамен Cisco 100-105 требовался для получения:

• Сертификация CCNA Routing and Switching — Cisco Certified Network Associate (CCNA) Routing and Switching
