CCNA3 Chapter 3 Practice Test Questions

A1 Switch A A2 A3

B1 B2 Switch B B3

C1 C2 Switch C C3

The network shown in the diagram has just been configured and none of the switches yet has any entries in its bridging table. Workstation A1 sends out a broadcast ARP request. What will happen? (Choose two)  All nine workstations will receive the ARP request.  Only Switch A will receive the ARP request.  All devices on VLAN 1 will receive the ARP request.  Workstations connected to Switch A will receive the ARP request.  Switch A will put the MAC address of workstation A1 into its bridging table.  The router will flood the ARP request to all VLANs.

Workstation A1 in the diagram sends a unicast frame to workstation C2. What must happen in order for C2 to receive the frame?  Nothing. VLAN trunking will ensure that C2 receives the frame.  C2 cannot receive the frame because it is on a different VLAN from A1.  C2 cannot receive the frame because it is attached to a different switch from A1.  The router must be configured so that it can route between the VLANs.  Switch A must be configured to route frames between the VLANs.

How many VLANs can be configured on a Catalyst switch?

99 255 1024 4096 A switch is configured with four VLANs. Which is true?

SW 23/10/2007 D:\Docs\2018-01-08\043fb446d29330ac5eaa88dd4c8b3113.doc 1  Each VLAN forms its own broadcast domain.  Each VLAN is a separate subnet and needs its own subnet address.  The Switch keeps a separate bridging table for each VLAN.  All of the above.

Which VLAN is used for STP and CDP messages?

VLAN 1 The management VLAN The native VLAN The data VLAN Any VLAN you choose

Which is true of a static VLAN?  VLAN membership depends on the MAC address of the workstation.  VLAN membership depends on the IP address of the workstation.  VLAN membership depends on the Switch port to which the workstation is connected.  It is not possible to change the VLAN membership once it has been configured.  Static VLANs require the use of special software packages such as CiscoWorks 2000.

Which is true of a dynamic VLAN?  VLAN membership depends on the MAC address of the workstation.  VLAN membership depends on the Switch port to which the workstation is connected.  It is not possible to change the VLAN membership once it has been configured.  Dynamic VLANs have become common since the introduction of DHCP.

You have configured static VLANs on a switch. The marketing department uses VLAN 4. A member of the marketing department moves to a different office, taking her PC with her. What needs to be done?  Nothing. The PC will be recognised in its new position and will stay on VLAN 4.  The cabling must be altered so that the PC is still connected to one of the Switch ports on VLAN 4.  The Switch configuration must be altered so that the port connected to the PC is reassigned to VLAN 4.  The VLAN must be changed to a dynamic VLAN.

A switch has static VLANs configured. Three workstations are connected to the same Switch port by using a hub. What is the effect of this?  The three workstations must be on the same VLAN.  The hub must be configured with the same static VLANs as the Switch.

SW 23/10/2007 D:\Docs\2018-01-08\043fb446d29330ac5eaa88dd4c8b3113.doc 2  The Switch must be configured with sub interfaces if the workstations are on different VLANs.  It is not possible for workstations to share a Switch port when VLANs are used.

The marketing department is on VLAN 4 and the sales department is on VLAN 5. How can a member of the marketing department communicate with a member of the sales department?  The Switch will detect that the destination is on a different segment and flood packets through all ports  The Switch needs to be configured to pass packets between different VLANs.  The packets must be sent via an enterprise server.  A router is needed to route packets between different VLANs.

1A new switch has the default configuration. Which of the following are true? (Choose two)  VLAN 1 exists, and all ethernet ports are assigned to it.  Each group of eight ports is assigned to a different VLAN.  An IP address is assigned to VLAN 1.  There may be default VLANs for different LAN technologies, such as token Ring and FDDI.

An administrator wants to configure an IP address on a switch so that the switch can be configured remotely. What should the administrator do?  Configure the IP address on port 0/1.  Configure the IP address on all ports.  Configure the IP address on the management VLAN.  Configure the IP address on all VLANs.  You cannot configure an IP address on a switch.

1Where is frame tagging necessary to identify VLAN membership?  Between the source workstation and the nearest switch.  Between switches if a link carries frames belonging to more than one VLAN.  Between switches if a link carries frames belonging to only one VLAN.  Between the switch and the destination workstation.

Which statements are true of IEEE 802.1Q frame tagging? (Choose two)  It is a Cisco proprietary encapsulation protocol.  It inserts a VLAN identifier and other fields into the frame header.  It encapsulates the frame with an additional header.  It is now the preferred method for identifying VLAN traffic between switches.  It used to be the most common method for identifying VLAN traffic between switches, but it is not in common use any more.

Where is frame tagging added to the frame?

SW 23/10/2007 D:\Docs\2018-01-08\043fb446d29330ac5eaa88dd4c8b3113.doc 3  At the source host workstation.  At the destination host workstation.  At a switch, before the frame is placed on a trunk connection.  At a switch, after the frame is received from a trunk connection.

Where is frame tagging removed from the frame?  At the source host workstation.  At the destination host workstation.  At a switch, before the frame is placed on a trunk connection.  At a switch, after the frame is received from a trunk connection.

Which commands would you use in order to create a VLAN number 4, called Marketing?  Switch# vlan 4 Switch(vlan)#name Marketing  Switch(config)# vlan 4 Switch(config-vlan)#name Marketing  Switch(config)#vlan access Switch(config)#vlan 4 name Marketing  Switch(vlan)#vlan 4 Switch(vlan)#name Marketing  Switch(config)#vlan 4 Marketing

Which commands would you use in order to assign the fast ethernet port 0/7 to VLAN 4?

Ports 0/7, 0/8 and 0/9 all belong to VLAN 4. You give the command Switch(config)# no vlan 4 Which of the following statements are true? (Choose 2)  VLAN 4 has been deleted.  All three ports have been assigned to VLAN 1.

SW 23/10/2007 D:\Docs\2018-01-08\043fb446d29330ac5eaa88dd4c8b3113.doc 4  VLAN 4 still exists but the ports are no longer assigned to it.  All three ports are inactive and not assigned to any VLAN.  All three ports will be reassigned to VLAN 1 when the Switch is reset.

Which command would you give to view the contents of the VLAN database?  Switch#show vlan  Switch#show vlan database  Switch#(vlan)show vlan  Switch#(vlan)show vlan database  Switch#show database vlan

If you do not specify which VLANs are allowed on a trunk link, what will happen?

 No VLANs can send traffic over the link.  Only VLAN 1 can send traffic over the link.  Only the management VLAN can send traffic over the link.  All VLANs can send traffic over the link.

Which is true about VLAN information?

 You should save the running configuration so that VLAN information is held in the startup configuration.  VLAN information is held in the VLAN database in flash memory.  You can remove VLAN information by giving the erase start command and reloading.  VLAN information is not saved, but is re-learned from neighbouring switches on start-up by using CDP.

IEEE 802.1q and ISL are:

 Different encapsulation methods for tagging frames on trunk links.  Both supported on all Cisco Catalyst switches.  Different methods of assigning devices to VLANs.  Different methods of sharing VLAN information between switches.

SW 23/10/2007 D:\Docs\2018-01-08\043fb446d29330ac5eaa88dd4c8b3113.doc 5 A switch port has been configured as follows:

SW1(config)#int fa 0/12 SW1(config-if)#mls qos trust cos SW1(config-if)#switchport voice vlan 150 SW1(config-if)#switchport mode access SW1(config-if)#switchport access vlan 5 SW1(config-if)#end

Which is true?

 There is a conflict because the port has been configured on two VLANs.  The port is on VLAN 5 only, because the later configuration replaces the earlier configuration.  The port can handle both voice and data traffic.  The port will give priority to traffic on VLAN 5.
