642-813 Q&A – Implement VLAN based solution (56-60)

Section 1 – Implement VLAN based solution, given a network design and a set of requirements

QUESTION NO: 56
What is a characteristic of assigning a static VLAN membership?
A. VMPS server lookup is required
B. Easy to configure
C. Easy of adds, moves, and changes
D. Based on MAC address of the connected device
Answer: B

Explanation:
Static port VLAN membership on the switch is assigned manually by the administrator on a portby- port basis.
Characteristics of static VLAN configurations include the following:
1. Secure
2. Easy to configure
3. Straight forward to monitor
4. Works well in networks where moves, adds , and changes are rare.
Incorrect Answers:
A: VMPS server lookups are a function of dynamic VLANs and are not used with statically assigned VLANs.
C: Moves, adds, and changes, would require a network administrator to change the configuration of the switch every time a change is required.
D: This would describe a function of dynamic VLAN configurations, where the MAC address of the end user determines the VLAN that it belongs in, instead of the physical port.

What command could you enter to display the trunking status of a module/port in the switch?
(Type in the answer below):
Answer: show trunk

QUESTION NO: 58
Switch R1 has been configured with DTP using the desirable option. Which statement describes Dynamic Trunking Protocol (DTP) desirable mode?
A. The interface actively attempts to convert the link to a trunk link.
B. The interface is put into permanent trunking mode but prevented from generating DTP frames.
C. The interface is put into permanent trunking mode and negotiates to convert the link into a trunk link.
D. The interface is put into a passive mode, waiting to convert the link to a trunk link.
E. None of the other alternatives apply
Answer: A
Explanation:
In the switchport mode command, you can set the trunking mode to any of the following: trunk –
This setting places the port in permanent trunking mode. The corresponding switch port at the other end of the trunk should be similarly configured because negotiation is not allowed. You should also manually configure the encapsulation mode. dynamic desirable (the default)-The port actively attempts to convert the link into trunking mode. If the far-end switch port is configured to trunk , dynamic desirable , or dynamic auto mode, trunking is successfully negotiated. Dynamic auto -The port converts the link into trunking mode. If the far-end switch port is configured to trunk or dynamic desirable , trunking is negotiated. Because of the passive negotiation behavior, the link never becomes a trunk if both ends of the link are left to the dynamic auto default.

QUESTION NO: 59
What are some virtues of implementing end-to-end VLANs? (Choose two)
A. End-to-end VLANs are easy to manage.
B. Users are grouped into VLANs independent of a physical location.
C. Each VLAN has a common set of security and resource requirements for all members.
D. Resources are restricted to a single location.
Answer: B,C
Explanation:
In an end-to-end VLAN, users are grouped into VLANs independent of physical location and dependent on group or job function.
Each VLAN has a common set of security requirements for all members.
Incorrect Answers:
A: End to end VLANs are more difficult to manage than local VLANs, due to the physical distances that they can span.
D: In an end-to-end VLAN, network resources are generally distributed across the entire enterprise wide area network.

QUESTION NO: 60
You need to configure a new Company switch to support DTP. Which DTP switchport mode parameter sets the switch port to actively send and respond to DTP negotiation frames?
A. Access
B. No negotiate
C. Trunk
D. Dynamic desirable
E. Dynamic auto
F. None of the other alternatives apply
Answer: D
Explanation:
Dynamic desirable (the default)-The port actively attempts to convert the link into trunking mode. If the far-end switch port is configured to trunk , dynamic desirable , or dynamic auto mode, trunking is successfully negotiated.
