CCNA3 FINAL EXAM NEW EXPLORATION #5

41. Refer to the exhibit. How is port Gi1/1 on SwT-A functioning in the spanning-tree topology?

It is sending and receiving data frames
It is receiving BPDUs, but not sending data frames
It is participating in the election process by forwarding the BPDUs it receives
It is receiving BPDUs and populating the MAC address table, but not sending data

42. Refer to the exhibit. Sw-T has been configured with a single trunking interface. Which VLANs will be allowed across the trunk?

Only VLAN 1 will be allowed across the trunk
All configured VLANs will be allowed across the trunk
Only the native VLAN wil be allowed across the trunk
Only the the management and native VLANs will be allowed across the trunk
Only VLANs that are configured on the VTP server in the domain will be allowed across the trunk

43. Refer to the exhibit.Router RA receives a packet with a source address of 192.168.1.65 and destination address of 192.168.1.161. What will the router do with this packet?

The router will drop the packet
The router will forward the packet out interface FastEthernet 0/1.1
The router will forward the packet out interface FastEthernet 0/1.2
The router will forward the packet out interface FastEthernet 0/1.3
The router will forward the packet out interface FastEthernet 0/1.2 and interface FastEthernet 0/1.3

44. Refer to the exhibit. How will switch S2 manage traffic coming from host PC1?

S2 will drop the traffic, unless it is management traffic
S2 will tag the frame with VLAN ID 99 when it forwards it over the trunk link
S2 will leave the traffic untagged when it forwards it over a trunk link
S2 will tag the traffic with the highest VLAN ID value when it forwards it over the trunk link

45. What is the purpose of VLAN trunking?

It improves network performance by reducing broadcast traffic
It select the best path to transmit data in a switched network
It carries the traffic of multiple VLANs through a single link
It avoids spanning tree loops in a switched network

46. Refer to the exhibit. The network administrator needs to remove the east-hosts VLAN and use the switch port from that VLAN in one of the existing VLANs. Which two sets of commands should be used when completely removing VLAN 2 from S1-Central ehile leaving the switch and all its interfaces operational?(Choose two)

S1-Central>enable
S1-Central#reload

S1-Central>enable
S1-Central#erase flash:

S1-Central>enable
S1-Central#delete flash:vlan.dat

S1-Central>enable
S1-Central#configure terminal
S1-Central(config)#no vlan 2

S1-Central>enable
S1-Central#configure terminal
S1-Central(config-if)#interface fastethernet 0/1
S1-Central(config-if)#switchport access vlan 3

47. Refer to the exhibit. What three statements describe why Host1 and Host2 are unable to communicate?(Choose three)

The switch ports are o different VLANs
The switch IP address is on the wrong subnet
The hosts are configured on different logical networks
A router is required to forward traffic between Host1 and Host2
The VLAN port assignments must be contiguous for each VLAN
The host default gateway addresses must be on the same logical network

48. Refer to the exhibit. Router R-West and switch S-West1 are connected via a single ethernet cable between the router interface fa0/0 and the switch interface fa0/1. The router and switch have been configured with the commands that are displayed in the exhibit. The network administrator enters the show interfaces trunk command and receives the output as shown. What is the cause of the "not-trunking" status for switch port Fa0/1?

The trunk is established, but no VLANs have been configured to
use it
The router is missing the dynamic trunking protocol statements
necessary to form a trunk
Because the router does not support Dynamic Trunking Protocol, the trunk has not been established
The router, the switch, or both must be configured with the dynamic desirable option for Dynamic Trunking Protocol to establish a trunk

49. Refer to the exhibit. Which two facts about STP can be determined from the displayed output?(Choose two)

Switch S1 has the lowest configured STP priority in the network

Switch S1 is configured as the root bridge for VLAN1
Fa0/21 is the root port of switch S1
Fa0/22 is the redundant link
Fa0/24 is considered the best path to the root bridge

50. Refer to the exhibit. In what two ways will the router handle VLAN traffic that is received on the trunk?(Choose two)

Traffic to VLAN 1 received by the router interface Fa0/0 will be dropped by the router Because interface Fa0/0 requires an iP address, the router will not be able to route between the VLANs Packets that are received from network 192.168.20.0/24 will be handled by subinterface Fa0/0.20 The router will use subinterface MAC addersses to identify the VLAN traffic that is received on the physical interface The router will continue to process traffic from the attached VLANs even if the physical interface goes down
