    Which statement most accurately describes static and dynamic routes?

    • Dynamic routes are manually configured by a network admin, whereas static routes are automatically learned and adjusted by a routing protocol

    • Static routes are manually configured by a network admin, whereas dynamic routes are automatically learned and adjusted by a routing protocol

    • Static routes tell the router how to forward packets to the networks that are not directly connected, whereas dynamic routes tell the router how to forward packets to networks that are directly connected

    • Dynamic routes tell the router how to forward packets to the networks that are not directly connected, whereas static routes tell the router how to forward packets to networks that are directly connected

    Correct Answer
    A. Static routes are manually configured by a network admin, whereas dynamic routes are automatically learned and adjusted by a routing protocol
    Explanation
    Static routes are routes that are manually configured by a network administrator. These routes are set up by specifying the destination network and the next hop or exit interface for the router to use when forwarding packets to that network. Static routes do not adjust or change automatically.

    Dynamic routes, on the other hand, are routes that are automatically learned and adjusted by a routing protocol. A routing protocol is a set of rules and algorithms that routers use to exchange information about the networks they are connected to. The routing protocol dynamically updates the routing table, which contains information about the best path to reach different networks.

    So, the correct statement is that static routes are manually configured by a network admin, whereas dynamic routes are automatically learned and adjusted by a routing protocol.

    When a router receives a packet with a destination address that is within an unkown subnetwork of a directly attached network, what is the default behavior ip the ip classless command is not enabled?

    • Drop the packet

    • Forward the packet to the default route

    • Forward the packet to the next hop for the directly attached network

    • Broadcast the packet through all the interfaces except the one on which it was received

    Correct Answer
    A. Drop the packet
    Explanation
    If the "ip classless" command is not enabled, the default behavior when a router receives a packet with a destination address within an unknown subnetwork of a directly attached network is to drop the packet. This means that the router will not forward the packet to any other destination or broadcast it through any interfaces. Instead, it will simply discard the packet, effectively preventing it from reaching its intended destination.

    How does  a distance vector router learn about paths for networks that are not directly connected?

    • From the source router

    • From neighboring routers

    • From the destination router

    • Learns only about directly connected networks

    Correct Answer
    A. From neighboring routers
    Explanation
    A distance vector router learns about paths for networks that are not directly connected from neighboring routers. Distance vector routing protocols, such as Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP), use a routing algorithm that determines the best path to a destination network based on the distance (or metric) and the direction (or vector) to that network. By exchanging routing information with neighboring routers, a distance vector router can learn about networks that are not directly connected and update its routing table accordingly.

    Rate this question:

  • 29. 

    What does a distance vector router send to its neighboring routers as apart of a periodic routing table update?

    What is that max allowable hop count for RIP

    • 6

    • 15

    • 30

    • 60

    Correct Answer
    A. 15
    Explanation
    The maximum allowable hop count for RIP (Routing Information Protocol) is 15. This means that RIP will only consider routes that are within 15 hops away from the source. If a route exceeds this hop count, it will be considered unreachable. RIP uses hop count as a metric to determine the best path for routing packets in a network. By limiting the hop count to 15, RIP ensures that the network topology remains relatively small and prevents routing loops or excessive delays in packet delivery.

    Which two statements best decribe the functions of a router in a network

    • Routers maintain their routing tables and ensure that other routers know of changes in the network

    • Routers use the routing table to determine where to forward packets

    • Routers strengthen the signal over large distances in a network

    • Routers create larger collision domains

    • Routers use ICMP to communicate network information from their own routing table with other routers

    Correct Answer(s)
    A. Routers maintain their routing tables and ensure that other routers know of changes in the network
    A. Routers use the routing table to determine where to forward packets
    Explanation
    Routers maintain their routing tables and ensure that other routers know of changes in the network. This means that routers keep track of the available paths in a network and update their routing tables accordingly. They also communicate these changes to other routers so that they are aware of the updated network topology.

    Routers use the routing table to determine where to forward packets. The routing table contains information about the available paths and their associated costs. When a router receives a packet, it looks at the destination address and checks its routing table to determine the best path to forward the packet towards its destination. By using the routing table, routers can efficiently route packets through the network.

    A routing table contains routing information that helps a router determine the routing path. It is a database that is stored in a router and contains a list of available routes to different network destinations. The routing table includes information such as the destination network address, the next hop router, and the metric or cost associated with each route. By referencing the routing table, a router can determine the most appropriate path to send data packets to their intended destination.

    If a router does not match the appropriate address portions to a number on its routing table, it?

    • Sends the packet back to the sender

    • Passes the packet to the next router in the hierarchy

    • Adds that number to its table

    • Discards the packet

    Correct Answer
    A. Discards the packet
    Explanation
    When a router does not find a match for the appropriate address portions in its routing table, it discards the packet. This means that the router does not have any information on how to forward the packet to its intended destination. Discarding the packet ensures that it does not continue to be passed along the network, preventing unnecessary network congestion.

    Which statement best describes what the user EXEC mode command allows you to configure on a Cisco router?

    • You cannot configure anything; the user mode commands are used to display information

    • The user EXEC mode allows you to perform lgobal config tasks that affect the entire router

    • The user EXEC mode commands allow you to enter a secret password so that you can configure the router

    • The user EXEC mode commands allow you to configure interfaces, subinterfaces, lines, and routers

    Correct Answer
    A. You cannot configure anything; the user mode commands are used to display information
    Explanation
    The correct answer states that the user EXEC mode commands do not allow the user to configure anything on a Cisco router. Instead, these commands are used solely to display information.

    When configuring NAT, the internet interface would be considered which of he following? 

    • NAT local interface

    • NAT inside interface

    • NAT global interface

    • NAT outside interface

    Correct Answer
    A. NAT outside interface
    Explanation
    The internet interface in NAT is considered the "NAT outside interface." This interface connects the local network to the internet and is responsible for translating the private IP addresses of the local network to a public IP address that can be used on the internet. The NAT outside interface is typically connected to the router or firewall that connects the local network to the internet.

    What does the ppp authentication chap pap command configure?

    • Chap authentication will always be used

    • Either CHAP or PAP will be used, selected at random for security

    • CHAP authentication will be used unless the remote router requests PAP

    • If authentication fails using CHAP, then PAP authentication is attempted

    Correct Answer
    A. If authentication fails using CHAP, then PAP authentication is attempted
    Explanation
    The correct answer states that if authentication fails using CHAP, then PAP authentication is attempted. This means that the ppp authentication chap pap command configures the router to first try CHAP authentication. If the authentication fails, it will then attempt PAP authentication as a backup method.

    The command show startup-config displays the onfiguration in which location?

    • ROM

    • RAM

    • NVRAM

    • Flash memory

    Correct Answer
    A. NVRAM
    Explanation
    The command "show startup-config" displays the configuration stored in NVRAM. NVRAM stands for Non-Volatile Random Access Memory, which is a type of memory that retains its data even when the power is turned off. The startup-config file contains the configuration settings that are used when the device is powered on or restarted. By using the "show startup-config" command, the user can view and verify the configuration stored in NVRAM.

    Which Cisco IOS command enables a Telnet session to receive console messages

    • Terminal monitor

    • Terminal debug monitor

    • Terminal debug messages

    • Terminal console messages

    Correct Answer
    A. Terminal monitor
    Explanation
    The Cisco IOS command "terminal monitor" enables a Telnet session to receive console messages. This means that when this command is used, any console messages that are generated on the device will be displayed on the Telnet session. This is useful for troubleshooting and monitoring purposes as it allows the user to see important system messages without having physical access to the device's console.

    It is preferable to use debug commands during periods of blank network traffic and blank users

    • Lower, more

    • Lower, fewer

    • Higher, more

    • Higher, fewer

    Correct Answer
    A. Lower, fewer
    Explanation
    During periods of blank network traffic and blank users, it is preferable to use debug commands with lower intensity and fewer executions. This is because debug commands can generate a significant amount of output, which can overload the network and impact its performance. By using lower intensity and fewer executions of debug commands, the impact on network traffic and users is minimized, allowing for smoother operations.
