3.1.1 Introducing VLANs
Assessment Item:
Which two statements describe the benefits of VLANs? (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.

3.2.3 Trunking Modes
Assessment Item:
Refer to the exhibit. SW1 and SW2 are new switches being 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 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.

VLAN information is saved in the startup configuration.
Non-default VLANs created manually must use the extended range VLAN numbers.

3.2.3 Trunking Modes
Assessment Item:
What is the effect of the switchport mode dynamic desirable command?
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.

likely cause of this problem?
Cisco switches only support the ISL trunking protocol.

By default, Switch1 will only allow VLAN 5 across the link.

3.2.1 VLAN Trunks
Assessment Item:
What is a valid consideration for planning VLAN traffic across multiple switches?
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.

3.4.2 A Common Problem with VLAN Configurations
Assessment Item:
Refer to the exhibit. Company HR is adding PC4, a specialized application workstation, to a new company office. The
company will add a switch, S3, connected via a trunk link to S2, another switch. For security reasons the new PC
will reside in the HR VLAN, VLAN 10. The new office will use the 172.17.11.0/24 subnet. After installation, the
existing PCs are unable to access shares on PC4. What is the likely cause?
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 the other HR VLAN PCs.
A single VLAN cannot span multiple switches.
