When the router receives a packet, what information should I check so that the packet can be sent to an external destination?

    • Destination address MAC
    • Source IP address
    • Destination IP address
    • Source MAC address

    • Note:
    • When a router receives a packet, it checks the destination address of the packet and uses the routing table to find the best route to that network.

The network administrator enters a copy of the run-config startup-config command in what type of memory is the startup configuration stored?

    • Flash site
    • RAM
    • NVRAM
    • ROM

    • Note:
    • The router contains four types of memory:

      • RAM – a variable memory used to store the running IOS, the running configuration file, the routing table, the ARP table and as packet buffer.
      • ROM – Non-volatile memory used to store a limited version of the IOS, download instructions and basic diagnostic software.
      • NVRAM – non-volatile memory for saving the configuration startup file.
      • Flash – non-volatile memory used to store IOS and other system files.

What is the packet routing method used by the router for routing decisions when using the routing information base and the connection table?

    • quick change
    • Cisco Express Freight
    • Process change
    • Online process

    • Note:
    • Cisco Express Forwarding (CEF) is the fastest and most preferred switching method. It uses the FIB and the additional table to perform the packet switching task. These data structures change with the topology.

Close the gap.

When the router receives a packet, it examines the destination address of the packet and consults the routing table to determine the best route for the delivery of the packet.

What are the two functions of the router? (choose two.)

    • The router connects different IP networks.
    • It controls the data stream through layer 2 addresses.
    • It determines the best way to send parcels.
    • It allows segmentation on the second level.
    • It builds a routing table based on ARP requirements.

    • Note:
    • Routers connect multiple networks, determine the best path to send and route packets based on the IP address of the destination.

To send packets to an external destination, which three pieces of information must be configured on the host? (Select three.)

    • Host name
    • The IP address
    • Subnet mask
    • Standard Gateway
    • DNS server address
    • DHCP server address

    • Note:
    • The host can determine whether the target is on the same network or on an external network based on its IP address and subnet mask. If it is on a remote network, the host needs a default gateway configured to send packets to the remote destination. DNS servers translate names into IP addresses, and DHCP servers are used to automatically assign IP address information to hosts. None of these servers need to be configured for an easy remote connection.

Which software is used by the network administrator to store the initial configuration of the router?

    • SSH client software
    • Telnet client software
    • HTTPS client software
    • Client software for terminal emulation

    • Note:
    • Connection to the router’s console port is required to perform the initial configuration of the router. You need a console cable and terminal emulation software to connect to the console port. SSH, Telnet and HTTPS can be used to configure the router if the router is configured with IP addresses and its interface is accessible on the network.

See exhibition. The network administrator has configured R1 as shown in the figure. When an administrator checks the status of the serial port, the port is displayed as administratively unavailable. Which additional command should be entered on serial interface R1 to increase the interface?

  • CCNA2 v6.0 Chapter 1 Test 002

  • CCNA2 v6.0 Chapter 1 Test 002

    • ResolutionIPv6
    • clock frequency 128000
    • at the end of
    • from

    • Note:
    • By default, all router interfaces are disabled. To increase the interfaces, the administrator must run theno stopcommand in interface mode.

What is the IPv4 loopback interface on the Cisco IOS router?

    • No stop command is required to switch this interface to the UP state.
    • It is a logical interface integrated into the router.
    • Only one loopback interface can be activated on a router.
    • It is assigned to a physical port and can be connected to other devices.

    • Note:
    • A loopback is a logical interface built into the router that is automatically set to the UP state for as long as the router is active. It is not linked to any physical port and can therefore never be connected to any other device. You can activate multiple loopback interfaces on the router.

What are the two parts of the information displayed on the output of the short control ip interface? (choose two.)

    • IP addresses
    • MAC addresses
    • Level 1 status
    • convenience stores
    • Description of the interfaces
    • Speed and duplex parameters

    • Note:
    • Commandgives a short description of the ipinterface and shows the IP address of each interface and the operating status of the Layer 1 and Layer 2 interfaces. To view interface descriptions and speed and duplex parameters, use thecommand, which displays the currentinterface. The addresses of the following memories are displayed in the routing table with the commandshow ip route, and the MAC addresses of the interfaces can be viewed with the commandshow interfaces.

What are the two elements used by the host device when performing an AND operation to determine whether the destination address is on the same LAN? (Select two.)

    • Destination IP address
    • Destination address MAC
    • Source MAC address
    • Subnet mask
    • Network number

    • Note:
    • The result of the AND operation of any IP address with subnet mask is a network number. If the number of the source network matches the number of the destination network, the data remains on the local network. If the destination network number is different, the packet is sent to the default gateway (the router that sends the packet to the destination network).

See exhibition. PC A sends a request to server B. Which IPv4 address is used in the destination field of the packet when the packet leaves PC A?

  • CCNA2 v6.0 Chapter 1 Test 004

  • CCNA2 v6.0 Chapter 1 Test 004

    • 192.168.10.10
    • 192.168.11.1
    • 192.168.10.1
    • 192.168.12.16

    • Note:
    • The target IP address in packets does not change on the path between source and destination.

See exhibition.

What does R1 use as destination MAC address when building the frame from R1 to server B?

  • CCNA2 v6.0 Chapter 1 Test 005

  • CCNA2 v6.0 Chapter 1 Test 005

    • If the destination MAC address corresponding to the IPv4 address is not in the ARP cache, R1 sends an ARP request.
    • The package is encapsulated in the PPP frame and R1 adds the PPP destination address to the frame.
    • R1 uses the MAC address of destination S1.
    • R1 leaves the field empty and sends the data to the PC.

    • Note:
    • A connection within the local network uses the address resolution protocol to obtain a MAC address from a known IPv4 address. The MAC address is needed to build the frame into which the package is encapsulated.

See exhibition. If PC1 sends a packet to PC2 and the routing between two routers is configured, what does R1 do with the header of the Ethernet frame connected to PC1?

  • CCNA2 v6.0 Chapter 1 Test 006

  • CCNA2 v6.0 Chapter 1 Test 006

    • nothing, because the router has a route to the destination network.
    • Remove the Ethernet header and configure a new Layer 2 header before sending S0/0/0.
    • Open the header and replace the destination MAC address with a new one.
    • Open the header and use it to determine if S0/0/0 data is being sent.

    • Note:
    • If PC1 forms different headers that are linked to the data, such a header is a Layer 2 header. Since PC1 is connected to an Ethernet network, the Ethernet header is used. The source MAC address is the MAC address of PC1 and the destination MAC address is G0/0 at R1. When R1 receives this information, the router removes the header from layer 2 and creates a new header for the type of network where the data is to be placed (serial connection).

See exhibition. What does a router do with a packet that has a destination IP address of 192.168.12.227?

  • CCNA2 v6.0 Chapter 1 Test 001

  • CCNA2 v6.0 Chapter 1 Test 001

    • Drop the bag.
    • Send the packet with the Serial0/0/0/0 interface.
    • Send the package with the GigabitEthernet0/0 interface.
    • Send the package with the GigabitEthernet0/1 interface.

    • Note:
    • After the router has identified the destination network using the hidden subnet AND the destination IP address, the router checks the resulting destination network number in the routing table. If a match is found, the packet is sent to the interface associated with the network number. If no routing table is found for a particular network, the default gateway or the gateway of the last instance (if configured or known) is used. If there is no last instance gateway, the packet will be reset. In this case, the network 192.168.12.224 is not in the routing table and the router uses a last instance gateway. The port of the last instance is IP address 209.165.200.226. The router knows that this is the IP address connected to the network 209.165.200.224. The router then forwards the packet from the Serial0/0/0 interface or from the interface connected to 209.165.200.224.

What two explanations describe the terms administrative distance and metrically correct? (choose two.)

    • Administrative distance is the reliability of a given route.
    • The router first defines routes with larger administrative distances.
    • The value of the administrative distance cannot be changed by the network manager.
    • Routes with the lowest metric value to the destination indicate the best route.
    • Measurements are always determined by counting the hops.
    • The parameters vary depending on which layer 3 protocol is routed, e.g. IP.

Which two parameters are used as EIGRP parameters to select the best path to the network? (choose two.)

    • number of jumps
    • Bandwidth
    • stagger
    • Sustainability
    • Late arrival
    • Data protection

    • Note:
    • EIGRP uses bandwidth, latency, load and reliability as indicators to select the best path to the network.

What is the shortest administrative distance?

    • direct network
    • static path
    • the route received via the EIGRP routing protocol.
    • the route obtained by the OSPF routing protocol.

    • Note:
    • The most likely route or the route with the shortest administrative distance is the route directly connected to the router.

What two explanations describe the terms administrative distance and metrically correct? (choose two.)

    • Administrative distance is the reliability of a given route.
    • The router first defines routes with larger administrative distances.
    • The value of the administrative distance cannot be changed by the network manager.
    • Routes with the lowest metric value to the destination indicate the best route.
    • Measurements are always determined by counting the hops.
    • The parameters vary depending on which Layer 3 protocol is routed.

    • Note:
    • The metric is calculated by the routing protocol and used to determine the best path (lowest metric value) to the external network. Administrative Distance (AD) is used when a router has two or more routes to an external destination obtained from different sources. The source with the lowest AD is determined in the routing table.

Note: The following entry is included in the routing table for R1: .

D 10.1.1.0/24 [90/2170112] to 209.165.200.226, 00:00:05, Order No. 0/0/0

What is the value of Serial0/0/0 ?

    • This is the interface on R1 used for sending data, designed for 10.1.1.0/24.
    • This is interface R1, which was used to update the EIGRP.
    • This is the interface of the destination router, which is directly connected to the 10.1.1.0/24 network.
    • This is the interface of the next generation router if the target IP address is on the 10.1.1.0/24 network.

    • Note:
    • Serial0/0/0/0 points to the outgoing port on R1, which is used to send packets for the destination network 10.1.1.0/24.

See exhibition. The network administrator sends the show instead of 6 route command to R1. What are the two conclusions that can be drawn from the routing table? (choose two.)

  • CCNA2 v6.0 Chapter 1 Test 003

  • CCNA2 v6.0 Chapter 1 Test 003

    • R1 does not know the route to a remote network.
    • The FF00::/8 network is set with the static route control.
    • The Fa0/1 interface is configured with the IPv6 address 2001:DB8:ACAD:A::12.
    • Packages destined for the network 2001:DB8:ACAD:2::/64 are redirected via Fa0/1.
    • Packages destined for the network 2001:DB8:ACAD:2::54/128 are redirected via Fa0/0

    • Note:
    • According to the routing table, R1 has two directly connected networks and a multicast network (FF00::/8). He doesn’t know the routes to the remote networks. Local Host Interface Link – Record 2001:DB8:ACAD:A::12/128.

The network administrator configures the fa0/0 interface on the router R1 with the IP command 172.16.1.254 255.255.0. However, when the administrator gives the command to display the IP route, the routing table does not display the directly connected network. What is the possible cause of the problem?

    • Interface fa0/0 is not activated.
    • You must first save the configuration.
    • No packets with destination network 172.16.1.0 have been sent to R1.
    • The subnet mask is not correct for an IPv4 address.

    • Note:
    • A directly connected network is included in the routing table if these three conditions are met: (1) the interface is configured with a valid IP address; (2) it is activated by theno stopcommand; (3) it receives a carrier signal from another device connected to the interface. An incorrect subnet mask for an IPv4 address does not prevent it from appearing in the routing table, although an error can prevent a successful connection.

The network administrator configures the router using the ip-Route 0.0.0 command 209.165.200.226. What is the purpose of this team?

    • Send all packages to the device with IP address 209.165.200.226.
    • Insert a dynamic route for the destination network 0.0.0 in the routing table.
    • to forward packets destined for the 0.0.0.0 network to a device with the IP address 209.165.200.226
    • Specify a route for routing packets for which there is no route in the routing table.

    • Note:
    • The commandip route 0.0.0 0 0 0 0<next jump> adds the default route to the router’s route table. When a router receives a packet and has no specific route to reach its destination, it sends the packet to the next hop specified in the default route. The route created by theip-routecommand is a static route, not a dynamic route.

What are the two most common types of static routes in route tables? (choose two)

    • default static route
    • integrated static route of IOS
    • static route to a network
    • a static route divided over two adjacent routers.
    • converted a static route from an investigated route using a dynamic route protocol.

    • Note:
    • There are two common types of static routes in the route table, a static route to a specific network and a standard static route. The static route configured on the router can be distributed from the router to other adjacent routers. However, the distributed static route will be slightly different in the routing table on adjacent routers.

How does setting the IPv6 Unicast routing command affect the router?

    • Assign the router to the multicast group of all nodes
    • to make the router function as an IPv6 router
    • Only allows unicast packets on the router
    • to prevent the router from joining the multicast group all routers

    • Note:
    • When theipv6 Unicast Routingcommand is implemented on a router, it activates the router as IPv6. With this command you can also assign the router to the all-routers multicast group.

See exhibition. Compare the description with the data in the routing table. (not all options are used)
