01. Which two statements describe the benefits of VLANs? (Choose two.)
02. What are two characteristics of VLAN1 in a default switch configuration? (Choose two.)
- VLANs improve network 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.
02. 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.
- 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 a trunk.
- 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.

- A, B
- A, B, D, G
- A, D, F
- C, E
- C, E, F
- The VLANs may be named.
- VLAN information is saved 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.
- 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.
- Devices attached 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.
- 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 of that VLAN until the switch is rebooted. They then become members of the management VLAN.
- VLAN 1 can never be deleted.
- VLAN 1 can only be deleted by deleting the vlan.dat file.
- VLAN 1 can not be deleted until all ports have been removed from it.
- VLAN 1 can not be deleted until another VLAN has been assigned its responsibilities.
- DTP cannot negotiate the trunk since the native VLAN is not the default VLAN.
- The remote connected interface cannot negotiate a trunk unless it is also configured as dynamic desirable.
- The connected devices dynamically determine when data for multiple VLANs must be transmitted across the link and bring the trunk up as needed.
- A trunk link is formed if the remote connected device is configured with the switchport mode dynamic auto or switchport mode trunk commands.
- Cisco switches only support the ISL trunking protocol.
- The trunk cannot be negotiated with both ends set to auto.
- By default, Switch1 will only allow VLAN 5 across the link.
- A common native VLAN should have been configured on the switches.
- Disable DTP.
- Delete any VLANs currently being trunked through port Fa0/1.
- Administratively shut down and re-enable the interface to return it to default.
- Enter the switchport mode access command in interface configuration mode.
- The link between the switches is up but not trunked.
- VLAN 3 is not an allowed VLAN to enter the trunk between the switches.
- The router is not properly configured to route traffic between the VLANs.
- Computer D does not have a proper address for the VLAN 3 address space.
- There is a native VLAN mismatch.
- The link between Switch1 and Switch2 is up but not trunked.
- The router is not properly configured for inter-VLAN routing.
- VLAN 50 is not allowed to entering the trunk between Switch1 and Switch2.
- The default native VLAN is being used.
- The trunking mode is set to auto.
- Trunking can occur with non-Cisco switches.
- VLAN information about the interface encapsulates the Ethernet frames.
- Hosts on different VLANs use VTP to negotiate a trunk.
- Hosts on different VLANs communicate through routers.
- Hosts on different VLANs should be in the same IP network.
- Hosts on different VLANs examine VLAN ID in the frame tagging to determine if the frame for their network.
- none of the computers will receive the broadcast frame
- computer A, computer B, computer C
- computer A, computer D, computer G
- computer B, computer C
- computer D, computer G
- computer A, computer B, computer C, computer D, computer E, computer F, computer G, computer H, computer I
- Configuring interswitch connections as trunks will cause all hosts on any VLAN to receive broadcasts from the other VLANs.
- A trunk connection is affected by broadcast storms on any particular VLAN that is carried by that trunk.
- Restricting trunk connections between switches to a single VLAN will improve efficiency of port usage.
- Carrying all required VLANs on a single access port will ensure proper traffic separation.
- 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.
- dynamic desirable mode
- on or dynamic desirable mode
- on, auto, or dynamic desirable mode
- on, auto, dynamic desirable, or nonegotiate mode
- The switch to switch connection must be configured as an access port to permit access to VLAN 10 on S3.
- The new PC is on a different subnet so Fa0/2 on S3 must be configured as a trunk port.
- PC4 must use the same subnet as PC1.
- A single VLAN cannot span multiple switches.
- Enter the no vlan 2 and the vlan 3 commands in global configuration mode.
- Enter the switchport access vlan 3 command in interface configuration mode.
- Enter the switchport trunk native vlan 3 command in interface configuration mode.
- Enter the no shutdown in interface configuration mode to return it to the default configuration and then configure the port for VLAN 3.
