A router has two FastEthernet interfaces and needs to connect to fourVLANs in the local network. How can this be accomplished using the fewestnumber of physical interfaces without unnecessarily decreasing networkperformance?Implement a router-on-a-stick configuration.Add a second router to handle the inter-VLAN traffic.Use a hub to connect the four VLANS with a FastEthernet interface on the router.Interconnect the VLANs via the two additional FastEthernet interfaces.3. Refer to the exhibit. All devices are configured as shown in the exhibit.PC2 can successfully ping the F0/0 interface on R1.
PC2 cannot ping PC1.What might be the reason for this failure?R1 interface F0/1 has not been configured for subinterface operation.S1 interface F0/6 needs to be configured for operation in VLAN10.S1 interface F0/8 is in the wrong VLAN.S1 port F0/6 is not in VLAN10.Стр. 3 из 1701.04.2009 0:46CISCO CCNA Certifications: CCNA 3 UPDATEDfile:///D:/botalka/%D1%81%D0%B8%D1%81%D1%8C%D0%BA...4. Refer to the exhibit.
The commands for a router to connect to a trunkeduplink are shown in the exhibit. A packet is received from IP address192.168.1.54. The packet destination address is 192.168.1.120. What willthe router do with this packet?The router will forward the packet out interface FastEthernet 0/1.1 tagged for VLAN10.The router will forward the packet out interface FastEthernet 0/1.2 tagged for VLAN60.The router will forward the packet out interface FastEthernet 0/1.3 tagged for VLAN120.The router will not process the packet since the source and destination are on thesame subnet.The router will drop the packet since no network that includes the source address isattached to the router.5. What distinguishes traditional routing from router-on-a-stick?Traditional routing is only able to use a single switch interface.
Router-on-a-stickcan use multiple switch interfaces.Traditional routing requires a routing protocol. Router-on-a-stick only needs to routedirectly connected networks.Traditional routing uses one port per logical network. Router-on-a-stick usessubinterfaces to connect multiple logical networks to a single router port.Traditional routing uses multiple paths to the router and therefore requires STP.Router-on-a-stick does not provide multiple connections and therefore eliminatesthe need for STP.6. Which statement is true about ARP when inter-VLAN routing is beingused on the network?When router-on-a-stick inter-VLAN routing is in use, each subinterface has aseparate MAC address to send in response to ARP requests.When VLANs are in use, the switch responds to ARP requests with the MAC addressof the port to which the PC is connected.When router-on-a-stick inter-VLAN routing is in use, the router returns the MACaddress of the physical interface in response to ARP requests.When traditional inter-VLAN routing is in use, devices on all VLANs use the samephysical router interface as their source of proxy ARP responses.7.
What two statements are true regarding the use of subinterfaces forinter-VLAN routing? (Choose two.)subinterfaces have no contention for bandwidthmore switch ports required than in traditional inter-VLAN routingfewer router ports required than in traditional inter-VLAN routingsimpler Layer 3 troubleshooting than with traditional inter-VLAN routingless complex physical connection than in traditional inter-VLAN routing8. Which three elements must be used when configuring a router interfacefor VLAN trunking? (Choose three.)one subinterface per VLANone physical interface for each subinterfaceone IP network or subnetwork for each subinterfaceone trunked link per VLANa management domain for each subinterfacea compatible trunking protocol encapsulation for each subinterface9.
Refer to the exhibit. Which two statements are true about the operationof the subinterfaces? (Choose two.)Incoming traffic that has a VLAN ID of 2 is processed by subinterface fa0/0.2.Incoming traffic with VLAN ID 0 is processed by interface fa0/0.Subinterfaces use unique MAC addresses by adding the 802.1Q VLAN ID to thehardware address.Traffic inbound on this router is processed by different subinterfaces, depending onthe VLAN from which the traffic originated.Reliability of both subinterfaces is poor because ARP is timing out.Both subinterfaces remain up with line protocol up, even if fa0/0 line protocol isdown.10. Refer to the exhibit.
Port Fa0/0 on router R1 is connected to port Fa0/1on switch S1. After the commands shown are entered on both devices, thenetwork administrator determines that the devices on VLAN 2 are unable toping the devices on VLAN 1. What is the likely problem?R1 is configured for router-on-a-stick, but S1 is not configured for trunking.R1 does not have the VLANs entered in the VLAN database.Spanning Tree Protocol is blocking port Fa0/0 on R1.The subinterfaces on R1 have not been brought up with the no shutdown commandyet.11. Refer to the exhibit.
PC1 has attempted to ping PC2 but has beenunsuccessful. What could account for this failure?PC1 and R1 interface F0/0.1 are on different subnets.The encapsulation is missing on the R1 interface F0/0.An IP address has not been assigned to the R1 physical interface.The encapsulation command on the R1 F0/0.3 interface is incorrect.12. Refer to the exhibit. R1 is routing between networks 192.168.10.0/28and 192.168.30.0/28. PC1 can ping R1 interface F0/1, but cannot ping PC3.What is causing this failure?PC1 and PC3 are not in the same VLAN.Стр. 4 из 1701.04.2009 0:46CISCO CCNA Certifications: CCNA 3 UPDATEDfile:///D:/botalka/%D1%81%D0%B8%D1%81%D1%8C%D0%BA...The PC3 network address configuration is incorrect.The S1 interface F0/11 should be assigned to VLAN30.The F0/0 and F0/1 interfaces on R1 must be configured as trunks.13. Devices on the network are connected to a 24-port Layer 2 switch thatis configured with VLANs.
Switch ports 0/2 to 0/4 are assigned to VLAN 10.Ports 0/5 to 0/8 are assigned to VLAN 20, and ports 0/9 to 0/12 areassigned to VLAN 30. All other ports are assigned to the default VLAN.Which solution allows all VLANs to communicate between each other whileminimizing the number of ports necessary to connect the VLANs?Configure ports 0/13 to 0/16 with the appropriate IP addresses to perform routingbetween VLANs.Add a router to the topology and configure one FastEthernet interface on the routerwith multiple subinterfaces for VLANs 1, 10, 20, and 30.Obtain a router with multiple LAN interfaces and configure each interface for aseparate subnet, thereby allowing communication between VLANs.Obtain a Layer 3 switch and configure a trunk link between the switch and router,and configure the router physical interface with an IP address on the native VLAN.14.
Which two statements are true about the interface fa0/0.10 command?(Choose two.)The command applies VLAN 10 to router interface fa0/0.The command is used in the configuration of router-on-a-stick inter-VLAN routing.The command configures a subinterface.The command configures interface fa0/0 as a trunk link.Because the IP address is applied to the physical interface, the command does notinclude an IP address.15.
Refer to the exhibit. What two conclusions can be drawn from theoutput that is shown? (Choose two.)The no shutdown command has not been issued on the FastEthernet 0/0 interface.Both of the directly connected routes that are shown will share the same physicalinterface of the router.A routing protocol must be configured on the network in order for the inter-VLANrouting to be successful.Inter-VLAN routing between hosts on the 172.17.10.0/24 and 172.17.30.0/24networks is successful on this network.Hosts in this network must be configured with the IP address that is assigned to therouter physical interface as their default gateway.16. What are the steps which must be completed in order to enableinter-VLAN routing using router-on-a-stick?Configure the physical interfaces on the router and enable a routing protocol.Create the VLANs on the router and define the port membership assignments on theswitch.Create the VLANs on the switch to include port membership assignment and enablea routing protocol on the router.Create the VLANs on the switch to include port membership assignment andconfigure subinterfaces on the router matching the VLANs.17.
Refer to the exhibit. The network administrator correctly configures RTAto perform inter-VLAN routing. The administrator connects RTA to port 0/4on SW2, but inter-VLAN routing does not work. What could be the possiblecause of the problem with the SW2 configuration?Port 0/4 is not active.Port 0/4 is not a member of VLAN1.Port 0/4 is configured in access mode.Port 0/4 is using the wrong trunking protocol.18.
What is important to consider while configuring the subinterfaces of arouter when implementing inter-VLAN routing?The physical interface must have an IP address configured.The subinterface numbers must match the VLAN ID number.The no shutdown command must be given on each subinterface.The IP address of each subinterface must be the default gateway address for eachVLAN subnet.19.
in which situation could individual router physical interfaces be used forInterVLAN routing, instead of a router-on-a-stick configuration?a network with more than 100 subnetworksa network with a limited number of VLANsa network with experienced support personnela network using a router with one LAN interface20. Refer to the exhibit. Switch1 is correctly configured for the VLANs thatare displayed in the graphic.
The configuration that is shown was applied toRTA to allow for interVLAN connectivity between hosts attached to Switch1.After testing the network, the administrator logged the following report:Hosts within each VLAN can communicate with each other.Hosts in VLAN5 and VLAN33 are able to communicate with each other.Hosts connected to Fa0/1 through Fa0/5 do not have connectivity to host in otherVLANs.Why are hosts connected to Fa0/1 through Fa0/5 unable to communicatewith hosts in different VLANs?The router interface is shut down.The VLAN IDs do not match the subinterface numbers.All of the subinterface addresses on the router are in the same subnet.Стр.

Which two statements are true about the default operation of STP in aLayer 2 switched environment that has redundant connections betweenswitches? (Choose two.)The root switch is the switch with the highest speed ports.Decisions on which port to block when two ports have equal cost depend on the portpriority and identity.All trunking ports are designated and not blocked.Root switches have all ports set as root ports.Non-root switches each have only one root port.2.
Which two statements describe the BIDs used in a spanning treetopology? (Choose two.)They are sent out by the root bridge only after the inferior BPDUs are sent.They consist of a bridge priority and MAC address.Only the root bridge will send out a BID.They are used by the switches in a spanning tree topology to elect the root bridge.The switch with the fastest processor will have the lowest BID.3. In which two ways is the information that is contained in BPDUs used byswitches? (Choose two.)to negotiate a trunk between switchesto set the duplex mode of a redundant linkto identify the shortest path to the root bridgeto prevent loops by sharing bridging tables between connected switchesto determine which ports will forward frames as part of the spanning tree4.
