CCNA 3 Module 6 v.4

Refer to the exhibit. Which three statements describe the network design shown in the exhibit? (Choose three.)

This design will not scale easily.

This design exceeds the maximum number of VLANs that can be attached to a switch.

Devices on the different VLANs can communicate through the router.

This design requires the use of the ISL or 802.1q protocol on the links between the switch and the router.

This design uses more switch and router ports than are necessary.

The router merges the VLANs into a single broadcast domain.

A router has two serial interfaces and two FastEthernet interfaces. It needs to connect to a wide area link to the main office and to four VLANs in the local network. How can this be accomplished in the most efficient manner?

Connect a trunked uplink from the switch to a router FastEthernet interface and create logical subinterfaces for each VLAN.

Use a hub to connect the four VLANS with a FastEthernet interface on the router.

Two additional FastEthernet interfaces are required to interconnect the VLANs.

Use serial to FastEthernet transceivers to connect two of the VLANs to the router. Attach the other two VLANs directly to the available FastEthernet ports.

Add a second router to handle the inter-VLAN traffic.

Refer to the exhibit. PC2 pings the F0/0 interface on R1 and receives the correct ICMP echo reply. However, when PC2 attempts to ping PC1, an ICMP echo reply is not received. What could be the reason for this failure?

R1 interface F0/1 has not been configured for subinterface operation.

S1 interface F0/8 is in the wrong VLAN.

S1 port F0/6 is not in VLAN10.

S1 interface F0/6 needs to be configured for operation in VLAN10.

R1 interface F0/1 is in the wrong VLAN.

Refer to the exhibit. A router is configured to connect to a trunked uplink as shown in the exhibit. A packet is received on the FastEthernet 0/1 physical interface from VLAN 10. The packet destination address is 192.168.1.120. What will the router do with this packet?

The router will forward the packet out interface FastEthernet 0/1.1 tagged for VLAN 10.

The router will forward the packet out interface FastEthernet 0/1.2 tagged for VLAN 60.

The router will forward the packet out interface FastEthernet 0/1.3 tagged for VLAN 60.

The router will forward the packet out interface FastEthernet 0/1.3 tagged for VLAN 120.

The router will not process the packet since the source and destination are on the same subnet.

The router will drop the packet since no network that includes the source address is attached to the router.

What distinguishes traditional routing from router-on-a-stick?

Traditional routing is only able to use a single switch interface. Router-on-a-stick can use multiple switch interfaces.

Router-on-a-stick uses subinterfaces to connect multiple logical networks to a single router port. Traditional routing uses one port per logical network.

Traditional routing uses a routing protocol to update routes to other routers. Router-on-a-stick only routes to directly connected networks.

Router-on-a-stick does not provide multiple connections and therefore eliminates the need for STP. Traditional routing uses multiple paths to the router and therefore requires STP.

Traditional routing can use any router Ethernet ports. Router-on-a-stick requires VLAN-aware hardware.

Which statement is true about ARP when inter-VLAN routing is being used on the network?

When router-on-a-stick inter-VLAN routing is in use, each subinterface has a separate MAC address to send in response to ARP requests.

When VLANs are in use, the switch responds to ARP requests with the MAC address of the port to which the PC is connected.

When router-on-a-stick inter-VLAN routing is in use, the router returns the MAC address of the physical interface in response to ARP requests.

When traditional inter-VLAN routing is in use, devices on all VLANs use the same physical router interface as their source of proxy ARP responses.

What two statements are true regarding the use of subinterfaces for inter-VLAN routing? (Choose two.)

more switch ports required

less complex physical configuration

fewer router ports required

subinterfaces have no contention for bandwidth

less complex Layer 3 troubleshooting required if routing fails

Refer to the exhibit. If the router is connected to a switch with the default trunk configuration, which two items can be determined from the data shown? (Choose two.)

Interface Fast Ethernet 3/0 has an assigned IP address in the 192.168.5.0 network.

Subinterfaces have been defined.

The configuration is correct for full connectivity to a Catalyst switch.

Traffic cannot traverse VLAN 4.

No native is VLAN designated.

Which three elements must be used when configuring a router interface for VLAN trunking? (Choose three.)

one subinterface per VLAN

one physical interface for each subinterface

one IP network or subnetwork for each subinterface

one trunked link per VLAN

a management domain for each subinterface

a compatible trunking protocol encapsulation for each subinterface

Refer to the exhibit. What statement is true regarding the output shown?

The physical interface is not up.

The configuration for two physical trunk interfaces is shown in this output.

This device dynamically negotiated the trunk link using DTP.

Traffic for networks 10.10.10.0/24 and 10.10.11.0/24 are both being carried on the same physical interface.

Refer to the exhibit. Which two statements are true about the operation of 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 the hardware address.

Traffic inbound on this router is processed by different subinterfaces, depending on the 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 is down.

Refer to the exhibit. Port Fa0/0 on router R1 is connected to port Fa0/1 on switch S1. After the commands shown are entered on both devices, the network administrator determines that the devices on VLAN 2 are unable to ping 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 command yet.

Refer to the exhibit. Pc1 has attempted to ping Pc3 but has been unsuccessful. What could account for this failure?

PC1 and R1 interface F0/0/0.1 are on different subnets.

PC3 is on the wrong switch port.

The encapsulation type on the R1 interface F0/0/0 is incorrect.

An IP address has not been assigned to the R1 physical interface.

The encapsulation on the R1 F0/0/0.3 interface has been configured incorrectly.

Refer to the exhibit. R1 is configured to route between networks 192.168.10.0/28 and 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.

R1 does not have an active routing protocol.

The S1 interface F0/11 should be assigned to VLAN30.

The R1 interface F0/1 is incorrectly configured.

The PC3 network address configuration is incorrect.

Devices on the network are connected to a 24-port Layer 2 switch that is 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 are assigned to VLAN 30. All other ports are assigned to the default VLAN. Which solution allows all VLANs to communicate between each other while minimizing the number of ports necessary to connect the VLANs?

Configure ports 0/13 to 0/16 with the appropriate IP addresses to perform routing between VLANs.

Add a router to the topology and configure one Ethernet interface on the router with multiple subinterfaces for VLANs 1, 10, 20, and 30.

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.

Obtain a router with multiple LAN interfaces and configure each interface for a separate subnet, thereby allowing communication between VLANs.

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 not include an IP address.
