ccna 3 module 6

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

This design will not scale easily.
The router merges the VLANs into a single broadcast domain.
This design uses more switch and router ports than are necessary.
This design exceeds the maximum number of VLANs that can be attached to a switch.

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

If the physical interfaces between the switch and router are operational, the devices on the different VLANs can communicate through the router.

2. A router has two FastEthernet interfaces and needs to connect to four VLANs in the local network. How can this be accomplished using the fewest number of physical interfaces without unnecessarily decreasing network performance?

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.

4. Refer to the exhibit. The commands for a router to connect to a trunked uplink are shown in the exhibit. A packet is received from IP address 192.168.1.54. 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 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.

5. 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.
Traditional routing requires a routing protocol. Router-on-a-stick only needs to route directly connected networks.
Traditional routing uses one port per logical network. Router-on-a-stick uses subinterfaces 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 eliminates the need for STP.

6. 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.

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

10. 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?

PC1 and PC3 are not in the same VLAN.
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 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 FastEthernet interface on the router with multiple subinterfaces for VLANs 1, 10, 20, and 30.
Obtain a router with multiple LAN interfaces and configure each interface for a separate subnet, thereby allowing communication between VLANs.

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 physical interface of the router.
A routing protocol must be configured on the network in order for the inter-VLAN routing to be successful.
Inter-VLAN routing between hosts on the 172.16.10.0/24 and 172.16.30.0/24 networks is successful on this network.
Hosts in this network must be configured with the IP address that is assigned to the router physical interface as their default gateway.

Enabling PortFast on trunks that connect to other switches improves convergence.
If an access port is configured with PortFast, it immediately transitions from a blocking to a forwarding state.

11. What is the first step in the process of convergence in a spanning tree topology?
election of the root bridge
blocking of the non-designated ports
selection of the designated trunk port
determination of the designated port for each segment

12. How can a network administrator influence which STP switch becomes the root bridge?
Configure all the interfaces on the switch as the static root ports.
Change the BPDU to a lower value than that of the other switches in the network.
Assign a lower IP address to the switch than that of the other switches in the network.
Set the switch priority to a smaller value than that of the other switches in the network.

13. Which statement or set of paired statements correctly compares STP with RSTP?
STP and RSTP use the same BPDU format.
STP specifies backup ports. RSTP has only root ports, alternate ports, and designated ports.
STP port states are independent of port roles. RSTP ties together the port state and port role.
STP waits for the network to converge before placing ports into forwarding state. RSTP places alternate ports into forwarding state immediately.

14. When PVST+ was developed, the Bridge ID was modified to include which information?
bridge priority
MAC address
protocol
VLAN ID

15. Which two actions does an RSTP edge port take if it receives a BPDU? (Choose two.)
immediately loses its edge status
inhibits the generation of a TCN
goes immediately to a learning state
disables itself
becomes a normal spanning-tree port

16. What three link types have been defined for Rapid Spanning-Tree Protocol? (Choose three.)
shared
end-to-end
edge-type
boundary-type
point-to-many
point-to-point

17. Which three statements are accurate regarding RSTP and STP? (Choose three.)
RSTP uses a faster algorithm to determine root ports.
RSTP introduced the extended system ID to allow for more than 4096 VLANs.
Both RSTP and STP use the portfast command to allow ports to immediately transition to forwarding state.
Like STP PortFast, an RSTP edge port that receives a BPDU loses its edge port status immediately and becomes a normal spanning-tree port.
Configuration commands to establish primary and secondary root bridges are identical for STP and RSTP.
Because of the format of the BPDU packet, RSTP is backward compatible with STP.

18. Which two statements are true about the default operation of STP in a Layer 2 switched environment that has redundant connections between switches? (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 port priority 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.

19. Refer to the exhibit. What can be determined from the output shown?
Two hosts communicating between ports Fa0/2 and Fa0/4 have a cost of 38.
The priority was statically configured to identify the root.
STP is disabled on this switch.

S2 will automatically transition to VTP transparent mode.
S2 will remove all VLANs from the VLAN database until the cable is reconnected.
S2 will retain the VLANs as of the latest known revision, but will lose the VLANs if it is reloaded.
S2 will automatically send a VTP request advertisement to 172.17.99.11 when the cable is reconnected.

4. Refer to the exhibit. All switches in the VTP domain are new.
