Hoofdstuk 6 Flashcards
What are three primary benefits of using VLANs? (Choose three.)
security a reduction in the number of trunk links cost reduction end user satisfaction improved IT staff efficiency no required configuration
security
cost reduction
improved IT staff efficiency
Which type of VLAN is used to designate which traffic is untagged when crossing a trunk port?
data default native management
native
A network administrator is determining the best placement of VLAN trunk links. Which two types of point-to-point connections utilize VLAN trunking? (Choose two.)
between two switches that utilize multiple VLANs between a switch and a client PC between a switch and a server that has an 802.1Q NIC between a switch and a network printer between two switches that share a common VLAN
between two switches that utilize multiple VLANs
between a switch and a server that has an 802.1Q NIC
What must the network administrator do to remove Fast Ethernet port fa0/1 from VLAN 2 and assign it to VLAN 3?
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 command in interface configuration mode to return it to the default configuration and then configure the port for VLAN 3.
Enter the switchport access vlan 3 command in interface configuration mode.
When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default?
unused VLAN ID native VLAN ID data VLAN ID management VLAN ID
native VLAN ID
Port Fa0/11 on a switch is assigned to VLAN 30. If the command no switchport access vlan 30 is entered on the Fa0/11 interface, what will happen?
Port Fa0/11 will be shutdown. An error message would be displayed. Port Fa0/11 will be returned to VLAN 1. VLAN 30 will be deleted.
Port Fa0/11 will be returned to VLAN 1.
Which command is used to remove only VLAN 20 from a switch?
delete vlan.dat delete flash:vlan.dat no vlan 20 no switchport access vlan 20
no vlan 20
What happens to a port that is associated with VLAN 10 when the administrator deletes VLAN 10 from the switch?
The port becomes inactive. The port goes back to the default VLAN. The port automatically associates itself with the native VLAN. The port creates the VLAN again.
The port becomes inactive.
Which two characteristics match extended range VLANs? (Choose two.)
CDP can be used to learn and store these VLANs. VLAN IDs exist between 1006 to 4094. They are saved in the running-config file by default. VLANs are initialized from flash memory. They are commonly used in small networks.
VLAN IDs exist between 1006 to 4094.
They are saved in the running-config file by default.
A Cisco switch currently allows traffic tagged with VLANs 10 and 20 across trunk port Fa0/5. What is the effect of issuing a switchport trunk allowed vlan 30 command on Fa0/5?
It allows VLANs 1 to 30 on Fa0/5. It allows VLANs 10, 20, and 30 on Fa0/5. It allows only VLAN 30 on Fa0/5. It allows a native VLAN of 30 to be implemented on Fa0/5.
It allows only VLAN 30 on Fa0/5.
Refer to the exhibit. PC-A and PC-B are both in VLAN 60. PC-A is unable to communicate with PC-B. What is the problem?
The native VLAN should be VLAN 60. The native VLAN is being pruned from the link. The trunk has been configured with the switchport nonegotiate command. The VLAN that is used by PC-A is not in the list of allowed VLANs on the trunk.
The VLAN that is used by PC-A is not in the list of allowed VLANs on the trunk.
Refer to the exhibit. DLS1 is connected to another switch, DLS2, via a trunk link. A host that is connected to DLS1 is not able to communicate to a host that is connected to DLS2, even though they are both in VLAN 99. Which command should be added to Fa0/1 on DLS1 to correct the problem?
switchport nonegotiate switchport mode dynamic auto switchport trunk native vlan 66 switchport trunk allowed vlan add 99
switchport trunk native vlan 66
What is a characteristic of legacy inter-VLAN routing?
Only one VLAN can be used in the topology. The router requires one Ethernet link for each VLAN. The user VLAN must be the same ID number as the management VLAN. Inter-VLAN routing must be performed on a switch instead of a router.
The router requires one Ethernet link for each VLAN.
What is a disadvantage of using router-on-a-stick inter-VLAN routing?
does not support VLAN-tagged packets requires the use of more physical interfaces than legacy inter-VLAN routing does not scale well beyond 50 VLANs requires the use of multiple router interfaces configured to operate as access links
does not scale well beyond 50 VLANs
Refer to the exhibit. Router RA receives a packet with a source address of 192.168.1.35 and a destination address of 192.168.1.85. 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.
The router will forward the packet out interface FastEthernet 0/1.2.
