      Which of the following are the main components of a router? (Choose three.)

    • ROM

    • Flash Memory

    • CTG interfaces

    • NV-ROM

    • RAM

    Correct Answer(s)
    A. ROM
    A. Flash Memory
    A. RAM
    Explanation
    Routers have three main components: ROM, Flash Memory, and RAM. ROM (Read-Only Memory) stores the router's firmware, which contains the basic operating system. Flash Memory is used to store the router's configuration file and any software updates. RAM (Random Access Memory) is used for temporary storage of data and instructions while the router is operating. CTG interfaces and NV-ROM are not main components of a router.

    Rate this question:

  • 3. 

      Which of the following statements describe the function of RAM in a router? (Choose two.)

    • RAM stores the necessary Cisco IOS software for the router to begin booting.

    • RAM is not necessary if extra NVRAM is available.

    • RAM stores the current configuration information.

    • RAM is maintained when the router is turned off.

    • RAM stores routing tables for the router.

    Correct Answer(s)
    A. RAM stores the current configuration information.
    A. RAM stores routing tables for the router.
    Explanation
    RAM in a router serves multiple functions. It stores the current configuration information, which includes the settings and parameters that determine how the router operates. Additionally, RAM stores the routing tables for the router, which are crucial for determining the best path for data packets to reach their destination. It is important to note that RAM is volatile memory, meaning it does not retain data when the router is turned off. Therefore, it is necessary for the router to reload the configuration information and routing tables from other sources upon reboot.

    Rate this question:

  • 4. 

    Which of the following physical ports and/or cables on a router require clocking to be configured in a back-to-back connection? (Choose one.)

    • Serial port with DTE cable.

    • Console

    • Aux port

    • Ethernet

    • Serial port with DCE cable

    Correct Answer
    A. Serial port with DCE cable
    Explanation
    In a back-to-back connection, where two routers are directly connected to each other without any intermediate devices, the serial port with DCE (Data Communications Equipment) cable requires clocking to be configured. The DCE cable connects to the DTE (Data Terminal Equipment) port of the other router. Clocking is necessary in this scenario to synchronize the transmission and reception of data between the two routers. The other options, such as the console port, aux port, and Ethernet, do not require clocking in a back-to-back connection.

    Rate this question:

  • 5. 

    What are the possible functions of a console port? (Choose two.)

    • Storing routing information

    • Accessing the router to change configurations

    • Telnet access to the router

    • Password recovery

    • Backup to the smart serial connections

    Correct Answer(s)
    A. Accessing the router to change configurations
    A. Password recovery
    Explanation
    The console port on a router is used for accessing the router's command-line interface (CLI) to change configurations. It provides a direct connection to the router, allowing administrators to make changes to the device. Additionally, the console port can be used for password recovery in case the administrator forgets the login credentials. Both of these functions are essential for managing and troubleshooting the router.

    Rate this question:

  • 6. 

    Which of the following describe the function of flash memory in a router? ( Choose three.)

    • Holds the Cisco IOS software image

    • Replaces the need for RAM chips

    • Keeps its contents when a router is rebooted

    • Can store multiple versions of Cisco IOS software

    • Backs up configuration sites

    Correct Answer(s)
    A. Holds the Cisco IOS software image
    A. Keeps its contents when a router is rebooted
    A. Can store multiple versions of Cisco IOS software
    Explanation
    Flash memory in a router serves three functions. Firstly, it holds the Cisco IOS software image, which is the operating system of the router. Secondly, it retains its contents even when the router is rebooted, ensuring that the software image remains intact. Lastly, flash memory can store multiple versions of the Cisco IOS software, allowing for easy upgrades and the ability to switch between different software versions if needed.

    • Network

    • Physical

    • Presentation

    Correct Answer(s)
    A. Datalink
    A. Physical
    Explanation
    The term WAN refers to the Datalink and Physical layers of the OSI Model. The Datalink layer is responsible for framing data into frames and transmitting them over the physical medium, while the Physical layer deals with the actual transmission of bits over the network. In a WAN, data is typically transmitted over long distances using various physical media such as fiber optic cables, satellite links, or wireless connections. Therefore, the Datalink and Physical layers are the most relevant layers in the OSI Model when it comes to WANs.

    Rate this question:

  • 10. 

    Which Layer of the OSI Model is a Router at?

    • Transport

    • Data link

    • Network

    • Physical

    • Presentation

    Correct Answer
    A. Network
    Explanation
    A router operates at the Network layer of the OSI model. This layer is responsible for routing packets across different networks and determining the best path for data transmission. Routers use network addresses to make decisions about where to send data packets. They examine the destination IP address of a packet and use routing tables to determine the appropriate next hop for forwarding the packet. Therefore, a router operates at the Network layer to facilitate communication between different networks.

    If you borrow 4 bits from the host field of a Class C. What is the subnet mask?

    • 255.255.255.0

    • 255.255.192.0

    • 255.255.255.192

    • 255.255.255.240

    • 255.255.240.0

    Correct Answer
    A. 255.255.255.240
    Explanation
    When borrowing 4 bits from the host field of a Class C, it means that these 4 bits will be used to create subnets. The remaining bits in the host field will be used for host addresses. Since 4 bits can create a maximum of 16 subnets (2^4), the subnet mask will have 4 bits set to 1 and the rest set to 0. In binary, this is represented as 11110000, which is equivalent to 240 in decimal. Therefore, the subnet mask will be 255.255.255.240.

    Rate this question:

  • 13. 

    If you have a network with 5 subnets, how many bits do you borrow from a Class C to have enough sub-networks?

    • 2

    • 3

    • 4

    • 5

    • 1

    Correct Answer
    A. 3
    Explanation
    To determine the number of bits to borrow from a Class C network to have enough sub-networks, we need to find the smallest power of 2 that is greater than or equal to the number of subnets required. In this case, we have 5 subnets, so we need to find the smallest power of 2 that is greater than or equal to 5. The smallest power of 2 that satisfies this condition is 2^3, which is 8. Therefore, we need to borrow 3 bits from the Class C network to have enough sub-networks.

    Rate this question:

  • 14. 

    What is likely the reason for the following output from a router?CEntral_office# config trem                                 ^

    • The user is in the wrong mode for the configure command.

    • The prompt indicates that the user cannot configure the router

    • The ^ indicates that the letter r is not valid.

    • The word config should be entered as configuring.

    Correct Answer
    A. The ^ indicates that the letter r is not valid.
    Explanation
    The ^ symbol in the output indicates that the letter "r" is not valid. This suggests that there is a typographical error or a syntax error in the command "config trem". The router is expecting a valid command or keyword after the "config" keyword, and since "trem" is not recognized, the router displays the ^ symbol to indicate the invalid character.

    Rate this question:

  • 15. 

    Choose two statements that are true about setup mode?

    • It can be accessed using the setup command.

    • It is loaded by default instead of a saved configuration in NVRAM

    • It loads by default when a router is new and booted for the first time

    • After setup mode is entered, the configuration is applied unless the router is rebooted.

    Correct Answer(s)
    A. It can be accessed using the setup command.
    A. It loads by default when a router is new and booted for the first time
    Explanation
    Setup mode can be accessed using the setup command, which allows users to configure basic settings on a router. Additionally, setup mode is loaded by default when a router is new and booted for the first time, providing a guided configuration process for initial setup. Once setup mode is entered and the configuration is applied, it will remain in effect unless the router is rebooted.

    Rate this question:

  • 16. 

    Which command puts a router into routing protocol configuration mode?

    • Router rip

    • Ctrl-Z

    • Interface so/o/o

    • Network 201.203.20.0

    Correct Answer
    A. Router rip
    Explanation
    The correct answer is "router rip" because this command is used to enter the routing protocol configuration mode specifically for the Routing Information Protocol (RIP). In this mode, the router can be configured to use RIP as the routing protocol and various RIP-related parameters can be set. The other options, Ctrl-Z, interface so/o/o, and network 201.203.20.0, do not put the router into the routing protocol configuration mode.

    Rate this question:

  • 17. 

    Which of the following are operating environments for a router? Choose 2

    • Boot ROM (RX Boot)

    • RIP

    • ROM Monitor

    • OSPF

    • IGRP

    Correct Answer(s)
    A. Boot ROM (RX Boot)
    A. ROM Monitor
    Explanation
    Boot ROM (RX Boot) and ROM Monitor are both operating environments for a router. The Boot ROM (RX Boot) is a firmware program that is stored in read-only memory (ROM) and is responsible for initializing the router hardware and loading the initial software. The ROM Monitor, also known as ROMmon, is a special mode that allows the router to be managed and troubleshooted. It provides a basic command-line interface and can be used to recover the router in case of software or hardware failures. RIP, OSPF, and IGRP are routing protocols and not operating environments for a router.
