While configuring a router, the network engineer typed the following sequence: R1# show ip access-list
R1# show ip interface brief
R1# configure terminal
R1(config)# interface GigabitEthernet 0/2
R1(config-if)# description Protected Access
R1(config-if)# end
R1# The engineer is using the terminal history help feature to recall previously used commands. The engineer used the Up Arrow key twice. Which command from the sequence did the engineer recall?網路工程師在設定路由器時，輸入了下列指令順序：R1# show ip access-list
R1# show ip interface brief
R1# configure terminal
R1(config)# interface GigabitEthernet 0/2
R1(config-if)# description Protected Access
R1(config-if)# end
R1# 該工程師使用終端機歷史記錄輔助功能來回溯先前使用過的指令，並按了兩次向上鍵。工程師會回溯到序列中的哪個指令？

What is the expected result of the show running-config | exclude ! command executed on the Cisco IOS device?在 Cisco IOS 裝置上執行 show running-config | exclude ! 指令，預期會產生什麼結果？

CLI will display the negated versions of the commands in the running configuration file.CLI 會顯示執行組態檔中各指令的否定版本。CLI will display the running configuration file but without any lines containing "!" in themCLI 會顯示執行組態檔，但不含任何包含「!」的行。CLI will display only the lines copied from the external source.CLI 只會顯示從外部來源複製過來的行。CLI will display only the lines different to the lines in the startup-config file.CLI 只會顯示與啟動組態檔不同的行。

In Cisco IOS Software, what are the two EXEC access levels? (Choose two.)在 Cisco IOS 軟體中，兩種執行存取層級為何？（選擇兩項。）

admin EXECadmin EXECuser EXEC使用者執行模式（user EXEC）privileged EXEC特權執行模式（privileged EXEC）basic EXECbasic EXECadvanced EXECadvanced EXEC

Which Cisco IOS command do you use to change from user EXEC mode into privileged EXEC mode?要從使用者執行模式切換到特權執行模式，應使用哪個 Cisco IOS 指令？

Which three of the following commands can be used to exit the user EXEC mode in a Cisco CLI session? (Choose three.)在 Cisco CLI 工作階段中，下列哪三個指令可用來離開使用者執行模式？（選擇三項。）

How does the Privileged EXEC Mode restrict the access to the configuration CLI commands?特權執行模式如何限制對設定類 CLI 指令的存取？

The Privileged EXEC Mode provides access security by adding an additional password when trying to reach the configuration modes.特權執行模式在嘗試進入設定模式時，會要求額外的密碼以提供存取安全性。By default, the Privileged EXEC Mode asks users to enter passwords for entering the Global Configuration Mode.根據預設，特權執行模式會要求使用者輸入密碼才能進入全域設定模式。Access to the Privileged EXEC Mode can be password protected to allow only authorized users to execute the privileged set of commands可以對特權執行模式的存取設定密碼保護，只允許經授權的使用者執行特權指令集。Commands entered in the Privileged EXEC Mode intentionally show false device information for unauthorized users.在特權執行模式下輸入的指令，會刻意向未經授權的使用者顯示虛假的裝置資訊。

Which option is available to a network engineer to interact with a network device?網路工程師有哪個選項可用來與網路裝置互動？

A network engineer communicates directly with the device operating system using machine programming languages.網路工程師使用機器程式語言，直接與裝置的作業系統溝通。A shell program exposes operating system services and can be accessed via CLI or GUI.殼層程式（shell）會公開作業系統服務，可透過 CLI 或 GUI 存取。A hardware input device, such as mouse, can be used to directly interact with the device.可以使用滑鼠等硬體輸入裝置，直接與裝置互動。The operating system can only communicate with the user through light indicators present on the outside of the hardware.作業系統只能透過硬體外部的指示燈與使用者溝通。
