• 802.1q is Cisco proprietary.
• 802.1q frames are mapped to VLANs by MAC address.
• 802.1q does NOT require the FCS of the original frame to be recalculated.
• 802.1q will not perform operations on frames that are forwarded out access ports.
2. Which two statements describe the benefits of VLANs? (Choose two.)
• VLANs improvenetwork performance by regulating flow control and window size.
• VLANs enable switches to route packets to remote networks via VLAN ID filtering.
• VLANs reduce network cost by reducing the number of physical ports required on switches.
• VLANs improve network security by isolating users that have access to sensitive data and applications.
• VLANs divide a network into smaller logical networks,resulting in lower susceptibility to broadcast storms.
3. What are two characteristics of VLAN1 in a default switch configuration? (Choose two.)
• VLAN1 should renamed.
• VLAN 1 is the management VLAN.
• All switch ports are members of VLAN1.
• Only switch port 0/1 is assigned to VLAN1.
• Links between switches must be members of VLAN1.
4. Refer to the exhibit. SW1 and SW2 are new switchesbeing installed in the topology shown in the exhibit. Interface Fa0/1 on switch SW1 has been configured with trunk mode “on”. Which statement is true about forming a trunk link between the switches SW1 and SW2?
• Interface Fa0/2 on switch SW2 will negotiate to become a trunk link if it supports DTP.
• Interface Fa0/2 on switch SW2 can only become a trunk link if statically configured as atrunk.
• Interface Fa0/1 converts the neighboring link on the adjacent switch into a trunk link if the neighboring interface is configured in nonegotiate mode.
• Interface Fa0/1 converts the neighboring link on the adjacent switch into a trunk link automatically with no consideration of the configuration on the neighboring interface.
5. Refer to the exhibit. Computer 1 sends a frame to computer 4.On which links along the path between computer 1 and computer 4 will a VLAN ID tag be included with the frame?
• A, B
• A, B, D, G
• A, D, F
• C, E
• C, E, F
6. The network administrator wants to separate hosts in Building A into two VLANs numbered 20 and 30. Which two statements are true concerning VLAN configuration? (Choose two.)
• The VLANs may be named.
• VLAN information issaved in the startup configuration.
• Non-default VLANs created manually must use the extended range VLAN numbers.
• The network administrator may create the VLANs in either global configuration mode or VLAN database mode.
• Both VLANs may be named BUILDING_A to distinguish them from other VLANs in different geographical locations.
7. Refer to the exhibit. Which two conclusions can be drawnregarding the switch that produced the output shown? (Choose two.)
• The network administrator configured VLANs 1002-1005.
• The VLANs are in the active state and are in the process of negotiating configuration parameters.
• A FDDI trunk has been configured on this switch.
• The command switchport access vlan 20 was entered in interface configuration mode for Fast Ethernet interface 0/1.
• Devicesattached to ports fa0/5 through fa0/8 cannot communicate with devices attached to ports fa0/9 through fa0/12 without the use of a Layer 3 device.
8. What happens to the member ports of a VLAN when the VLAN is deleted?
• The ports cannot communicate with other ports.
• The ports default back to the management VLAN.
• The ports automatically become a part of VLAN1.
• The ports remain a part ofthat VLAN until the switch is rebooted. They then become members of the management VLAN.
9. A network administrator is removing several VLANs from a switch. When the administrator enters the no vlan 1 command, an error is received. Why did this command generate an error?
• VLAN 1 can never be deleted.
• VLAN 1 can only be deleted by deleting the vlan.dat file.
• VLAN 1 can not be deleted...
