Вопрос 1 к файлу 1.2.Pka. Почему нужно использовать привилегированный режим exec для изучения команд группы show в Cisco ios, использованный в данной лабораторной работе?

Необходимо использовать привилегированный режим EXEC, т.к. именно в том режиме доступны команды группы show (к примеру в пользовательском режиме эти команды не доступны).

Вопрос 2 к файлу 1.2.Pka. Сколько флэш-памяти имеет маршрутизатор?

Чтобы это определить необходимо открыть терминал на роутере и провести следующие действия:

ISPRouter#show flash

System flash directory:

File Length Name/status

1 13832032 c1841-ipbase-mz.123-14.T7.bin

[13832032 bytes used, 18682016 available, 32514048 total]

32768K bytes of processor board System flash (Read/Write)

Ответ: 32768 Кбайт

Вопрос 3 к файлу 1.2.Pka. Какая из следующих сетей разбивается на подсети?

209.165.201.0 – Разбивается на подсети

209.165.201.1

209.165.201.10

209.165.201.0 – разбивается на подсети.

Это видно из:

ISPRouter#show ip route

Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP

i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

* - candidate default, U - per-user static route, o - ODR

P - periodic downloaded static route

Gateway of last resort is not set
