What are three benefits of implementing VLANs? (Choose three)
A. A more efficient use of bandwidth can be achieved allowing many physical groups to use the same network
B. Broadcast storms can be mitigated by decreasing the escort girl paris number of broadcast domains,thus increasing their
C. A higher level of network security can be reached by separating sensitive data traffic from other network
D. Port-based vlans increase switch-port use efficient,thanks to 802.1Q trunks
E. A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network
F. Broadcast storms can be mitigated by increasing the number of broadcast domains,thus reducing their size.
G. VLANs make it easier for IT staff to configure new logical groups,because the vlans all belong to the same
Correct Answer: CEF
VLAN 3 is not yet configured on your switch. What happens if you set the switchport access vlan 3
interface configuration mode?
A. The command is accepted and the respective libertines girl paris VLAN is added to vlan.dat.
B. The command is rejected.
C. The command is accepted and you must configure the VLAN manually.
D. The port turns amber.
Correct Answer: A
Even VLAN 3 is not yet configured on the switch, we can set the switchport access vlan 3 command without no
problem and it also displays when we type the “show running-config” command.
What are three advantages of VLANs? (Choose three)
A. VLANs establish broadcast domains in switched networks.
B. VLANs utilize packet filtering to enhance network security.
C. VLANs provide a method of conserving IP addresses in large networks.
D. VLANs provide a low-latency internetworking alternative to routed networks.
E. VLANs allow access to network services based on department, not physical location.
F. VLANs can greatly simplify adding, moving, or changing hosts on the network.
Correct Answer: AEF
On corporate network, hosts on the same VLAN can communicate with each other, but they are unable to
communicate with hosts on different VLANs. What is needed to allow communication between the VLANs?
A. a router with subinterfaces configured on the physical interface that is connected to the switch
B. a router with an IP address on the physical interface connected to the switch
C. a switch with an access link that is configured between the switches
D. a switch with a trunk link that is configured between the switches
Correct Answer: A
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?
A. 802.1Q giants frames could saturate the link.
B. VLAN 10 on CAT1 and VLAN 1 on CAT2 will send untagged frames.
C. A native VLAN mismatch error message will appear.
D. VLAN 10 on CAT1 and VLAN 1 on CAT2 will send tagged frames.
Correct Answer: C
Which of the following are benefits of VLANs? (Choose three)
A. They increase the size of collision domains.
B. They allow logical grouping of users by function.
C. They can enhance network security.
D. They increase the size of broadcast domains while decreasing the number of collision domains.
E. They increase the number of broadcast domains while decreasing the size of the broadcast domains.
F. They simplify switch administration.
Correct Answer: BCE
When using VLAN the number and size of collision domains remain the same -> A is not correct.
VLANs allow to group users by function, not by location or geography -> B is correct.
VLANs help minimize the incorrect configuration of VLANs so it enhances the security of the network -> C is
VLAN increases the size of broadcast domains but does not decrease the number of collision domains -> D is
VLANs increase the number of broadcast domains while decreasing the size of the broadcast domains which
increase the utilization of the links. It is also a big advantage of VLAN -> E is correct.
VLANs are useful but they are more complex and need more administration -> F is not correct.
Which statement about vlan operation on Cisco Catalyst switches is true?
A. when a packet is received from an 802.1Q trunk,the vlan id can be dvcermined from the source MAC
B. unknown unicast frames are retransmitted only to the ports that belong to the same vlan.
C. ports between switches should be configured in access mode so that vlans can span across the ports.
D. broadcast and multicast frames are retransmitted to ports that are configured on different vlan.
Correct Answer: B
Which two benefits are provided by creating VLANs? (Choose two)
A. added security
B. dedicated bandwidth
C. provides segmentation
D. allows switches to route traffic between subinterfaces
E. contains collisions
Correct Answer: AC
Assuming the default switch configuration which vlan range can be added modified and removed on a Cisco
A. 2 through 1001
B. 1 through 1001
C. 1 through 1002
D. 2 through 1005
Correct Answer: A
