The Ideal Quiz On CCNA 2: Midterm Exam

When the "enable" command is entered, it allows the user to enter the privileged EXEC mode. This mode provides access to all the configuration and management commands on a network device. By entering the "enable" command, the user gains administrative privileges and can perform advanced tasks that are restricted in the user EXEC mode.

The "show version" command is used to display information about the version of the Cisco IOS software that is currently running on the router. This command provides details such as the IOS version number, the hardware platform, the amount of memory available, and other relevant information about the router's configuration and status.

Remote networks refer to networks that are located in a different location or are not directly connected to the current network. These networks can only be accessed by forwarding the packet through another router, as they are not within the immediate reach of the current network. Therefore, the correct answer is "remote".

The correct answer is "copy run start." This command is used to save the current configuration in RAM to NVRAM. It copies the running configuration file to the startup configuration file, which is stored in NVRAM.

Dynamic routing protocols typically use their own rules to build and update routing tables. A metric is the quantitative value used to measure the distance. The lowest metric is considered the best in dynamic routing protocols.

Volatile memory, also known as temporary memory, is stored in RAM (Random Access Memory). RAM is a type of computer memory that allows data to be read and written quickly, but it requires a constant power supply to retain its data. This makes it volatile because the data is lost when the power is turned off or interrupted. Unlike ROM (Read-Only Memory) and Flash memory, which are non-volatile and retain their data even without power, RAM is used for temporary storage of data that is actively being used by the computer.

Clock rate needs to be configured on the router running DCE. DCE stands for Data Circuit-terminating Equipment, which is responsible for providing clocking signals to the DTE (Data Terminal Equipment) devices connected to it. The clock rate is necessary for synchronization and timing purposes in the network. Therefore, the router running DCE needs to have the clock rate configured to ensure proper communication and synchronization with the connected DTE devices.

The startup configuration file is saved in NVRAM (Non-Volatile Random Access Memory). NVRAM is a type of memory that retains data even when the power is turned off or lost. It is commonly used in computer systems to store important configuration settings that need to be preserved during power cycles or system restarts. Therefore, the startup configuration file, which contains the initial settings and parameters for the system, is typically stored in NVRAM.

Before a PC can ping another PC on a different network, a static route using RIP (Routing Information Protocol) needs to be configured. RIP is a dynamic routing protocol that allows routers to exchange information about network reachability. By configuring a static route using RIP, the PC will know how to reach the destination network and can successfully ping the other PC. This ensures that the packets are correctly routed between the networks.

The running configuration file is located in RAM. RAM stands for Random Access Memory and it is a volatile memory that stores data and instructions that are currently being used by the system. The running configuration file contains the current configuration settings of the system and is stored in RAM to facilitate quick access and modification of the configuration.

The IP routing table is located in RAM. RAM stands for Random Access Memory, which is a type of computer memory that allows data to be read from and written to quickly. The routing table is a data structure that is used by routers to determine the best path for forwarding network packets. Storing the routing table in RAM allows for fast access and efficient routing decisions.

The router looks first in NVRAM to load the configuration file. NVRAM (Non-Volatile Random Access Memory) is a type of memory that retains its data even when the router is powered off or restarted. It is commonly used to store the router's startup configuration, including settings such as IP addresses, routing protocols, and security configurations. By looking in NVRAM first, the router ensures that it loads the most recent configuration file, allowing it to boot up with the correct settings.

The default sequence for loading the configuration is NVRAM, TFTP, Console. This means that the router will first check the NVRAM (Non-Volatile Random Access Memory) for a saved configuration. If there is no configuration found in the NVRAM, it will then look for a configuration file on a TFTP (Trivial File Transfer Protocol) server. If no configuration is found on the TFTP server, the router will finally prompt the user to enter a configuration using the console.

The permanent storage for the Cisco IOS is stored in Flash memory. Flash memory is a non-volatile storage medium that retains data even when power is removed. It is commonly used for storing the operating system and other essential files on networking devices like routers and switches. Flash memory provides fast access to the stored data and allows for easy upgrades or replacement of the IOS software.

DIMMS (Dual In-Line Memory Modules) are a type of memory module used in computers. They are typically located in the RAM (Random Access Memory) slots on the motherboard. RAM is a volatile memory that stores data that is actively being used by the computer's processor. It allows for fast read and write operations, making it ideal for temporary storage of data during program execution. Therefore, the correct answer is RAM.

The firmware containing boot instructions is saved in ROM (Read-Only Memory). ROM is a type of non-volatile memory that retains its contents even when the power is turned off. It is commonly used to store permanent instructions that are essential for the device's operation, such as the initial boot instructions. Unlike RAM (Random Access Memory) or NVRAM (Non-Volatile Random Access Memory), the contents of ROM cannot be modified or erased by normal computer operations. Flash memory, on the other hand, is a type of rewritable memory commonly used for storing data and firmware updates.

The command "show controllers" is used to view the configuration and status of hardware controllers on a device. By using this command, you can check if a clock rate has been set on a specific interface. This command provides detailed information about various controllers, including clocking information, which can help determine if a clock rate has been set on a particular interface.

The start-up configuration file includes the IP Address, Passwords, Hostname, RIP configuration, Bandwidth settings, Clock rate, and Default routes. These are essential components that need to be configured in the start-up configuration file for the proper functioning of the network. The IP Address is necessary for identifying and communicating with other devices on the network. Passwords are used for authentication and securing access to the network devices. The Hostname is a unique identifier for the network device. RIP (Routing Information Protocol) is a dynamic routing protocol that is configured in the start-up configuration file. Bandwidth and Clock rate settings are important for managing network performance. Default routes are used to forward packets when no specific route is available.
