CCNA VLAN -- 38 Questions

Question 1 What is the function of the command switchport trunk native vlan 999 on a Cisco Catalyst switch?

Question 2 A switch is configured with all ports assigned to VLAN 2.In addition, all ports are configured as full-duplex FastEthernet.What is the effect of adding switch ports to a new VLAN on the switch?

Question 3 What are three benefits of implementing VLAN's? (Choose three)

Question 4 Which IEEE standard protocol is initiated as a result of successful DTP completion in a switch over Fast Ethernet?

Question 5 Which of the following are benefits of VLAN's ? (Choose three)

Question 6 Which two commands can be used to verify a trunk link configuration status on a given Cisco switch? (Choose two)

Question 7

All switch ports are assigned to the correct VLANs, but none of the hosts connected to SwitchA can communicate with hosts in the same VLAN connected to switchB?
Based on the output shown, what is the most likely problem?

Question 8 Which two link protocols are used to carry mulitple VLANs over a single link ? (Choose two)

Question 9 Assuming the default switch configuration, which VLAN range can be added, modified and removed on a Cisco switch?

Question 10 Which statement about VLAN operation on Cisco Catalyst switches is true?

Question 11 Refer to the topology shown in the exhibit.
Which ports will be STP designated ports if all links are operating at the same bandwidth? (Choose three)

Question 12 Refer to the exhibit.
How should the FastEthernet0/1 ports on the 2950 model switches that are shown in the exhibit be configured to allow connectivity between all devices?

Question 13

A frame on VLAN 1 on switch S1 is sent to switch S2 when the frame is received on VLAN 2. What causes this behavior?

Question 14 Refer to the exhibit. Which statement is true?

Question 15 Which two benefits are provided by creating VLAN's? (Choose two)

Question 16 Refer to the exhibit.
Which two statements are true about inter VLAN routing in the topology that is shown in the exhibit? (Choose two)

Question 17

The network administrator normally establishes a Telnet session with the switch from host A. However, host A is unavailable. The administrator's attempt to telnet to the switch from host B fails, but pings to the other two hosts are successful. What is the issue?

Question 18 As a network technician, do you know which are valid modes for a switch port used as a VLAN trunk? (Choose three)

Question 19 Which three of these statements regarding 802.1Q trunking are correct? (Choose three)

Question 20 Refer to the exhibit.
The output that is shown is generated at a switch. Which three of these statements are true? (Choose three)

Question 21 What are the possible trunking modes for a switch port? (Choose three)

Question 22 What are three advantages of VLAN's? (Choose three)

Question 23 Refer to the diagram. All hosts have connectivity with one another.
Which statement describe the addressing scheme that is in use in the network? (Choose three)

Question 24 Refer to the exhibit.
Hosts on the same VLAN can communicate with each other but are unable to communicate with hosts on different VLAN's. What is needed to allow communication between VLAN's?

Question 25

C-router is to be used as a"router on-a-stick" to route between the VLAN's. All the interfaces have been properly configured and IP routing is operational. The hosts in the VLAN's have been configured with the appropriate default gateway. What can be said about this configuration?

Question 26 What commands must be configured on the 2950 switch and the router to allow communication between host 1 and host 2? (Choose two)

Question 27 Which three elements must be used when you configure a router interface for VLAN trunking? (Choose three)

Question 28

Question 29 A router has two Fast Ethernet interfaces and needs to connect to four VLAN's in the local network.How can you accomplish this task, using the fewest physical interfaces and without decreasing network performance.?

Question 30 Cisco Catalyst switches CAT1 and CAT2 have a connection between them using ports Fa0/13. An 802.1Q trunk is configured between the two switches. On CAT1, VLAN 10 is chosen as native, but on CAT2 the native VLAN is not specified. What will happen in this scenario?

Question 31

Question 32 Refer to the toplogy and router output shown in the exhibit. A technician is troubleshooting host connectivity issues on the switches. The hosts in VLANs 10 and 15 on Sw11 are unable to communicate with hosts in the same VLAN's on SW12. Hosts in the Admin VLAN are able to communicate
The port-to-VLAN assignments are identical on the two switches, What could be the problem?

Question 33

Question 34 VLAN 3 is not yet configured on your switch. What happens if you set the switchport access vlan 3 command in interface configuration mode?

Question 35

The network shown in the diagram is expecting connectivity problems. Which of the following will correct the problems? (Choose two).

Question 36

A problem with network connectivity has been observed. It is suspected that the cable connected to switch port Fa0/9 on Switch1 is disconnected?
What would be an effect of this cable being disconnected?

Question 37 Refer to the exhibit.
Switch port FastEternet 0/24 on ALSwitch1 will be used to create an IEEE802.1Q-compliant trunk to another switch. Based on the output shown, what is the reason the trunk does not form, even though the proper cabling has been attached ?

Question 38 In a switched environment, what does the IEEE 802.1Q standard describe?
