CCNA TEST ---SEM3 CH8 1 Which of the following states the 80/20 rule of end-to-end VLANs? 80% of network resources should be remote and 20% should be on the local VLAN. 80% of VLANs should be static and the remaining 20% should be dynamic. 80% of network traffic should be local and 20% remote. ¡Ì 80% of the network sources should be centralized at the core layer and the remaining 20% at the distribution layer. 80% of traffic should be routed and 20% should be switched.
Workstations, departments, and network resources are seldom moved. ¡Ì VLAN port membership frequently changes. Robust VLAN management software is available to the network administrator. ¡Ì The overhead required to manage VLAN MAC address and custom filtering tables is not desirable. VLANs are often added, deleted, and modified. ¡Ì
the physical addressing scheme traffic patterns in the network ¡Ì types of applications in use ¡Ì the adaptability of the network workgroup functions and commonality ¡Ì the tagging option used for VLAN identification

The root bridge timers control BPDU traffic on the network. ¡Ì Only the show commands on the switch can display root bridge information. It is the central point of a spanning tree topology. ¡Ì Storm control is enabled by default. VLANs cannot be trunked between switches until the root bridge has been elected.

They become inactive. ¡Ì They default back to the management VLAN. They automatically become a part of VLAN1. They must be assigned to another VLAN before the original VLAN can be deleted. They remain a part of that VLAN until the switch is rebooted. They then become members of the management VLAN.
logical addresses ¡Ì physical addresses ¡Ì ISL addresses switch port attachment ¡Ì hardware platform traffic pattern
The router IOS does not support trunking. ¡Ì The port is connected and is not receiving alignment and FCS errors. The switch duplex and speed are not set properly. ¡Ì The router and switch are running different versions of STP. The switch IP address is incorrectly configured.
The switch will discard the frame. The switch will request the sender resend the frame. The switch will map the source address to the port on which it was received. ¡Ì The switch will flood the frame to all attached devices. The switch will issue an ARP request to confirm that the source exists.
Enter database configuration mode. ¡Ì Reboot the switch in order for the changes to take effect. Use the negative form of the command that was used to create the VLAN. ¡Ì Reassign the switch ports from the deleted VLAN to other VLANs if they are to be used. ¡Ì Use the erase vlan command in global configuration mode. Delete the vlan.dat file from flash.

CDP messages are only sent on VLAN1. ¡Ì VLAN1 is reserved for links between switches. All switch ports are members of VLAN1. ¡Ì VLAN1 must be created before ports can be assigned to it. Only switch port 0/1 is assigned to VLAN1. An IP address configured on the switch will only apply to ports on VLAN1. ¡Ì
The traffic needs to be routed between the two VLANs. ¡Ì The hosts must be reconfigured to be on the same logical network. The VLANs need to be configured to be on the same broadcast domain. The switch must be configured to share VLAN traffic.
The frame header is in its original format when it reaches the endpoint device. ¡Ì The VLAN membership of frames does not need to be identified unless ISL is in use. The Ethernet frame is encapsulated or modified with the VLAN ID information. ¡Ì The VLAN ID is removed by the endpoint device upon delivery of the frame.
membership by MAC address membership by logical address membership by protocol membership by port ¡Ì membership by operating system

If the source is unknown, the source port is shutdown. If the source port of a frame is unknown, a bridge will issue an ARP request. If the destination is on another segment, the bridge forwards the frame only to the correct interface. ¡Ì A bridge forwards frames for unknown destinations to the default gateway. If the destination port is unknown, a bridge will flood the frame to all ports in the broadcast domain, except for the source port. ¡Ì If the destination of the frame is on the same segment as the source, a bridge will not forward the frame. ¡Ì

by centralizing departmental staff and network resources together in a single physical area by allowing organizational flexibility by grouping users together by function instead of physical location ¡Ì by simplifying the task of adding and moving network resources and users in a growing organization ¡Ì by reducing the number of broadcast domains in an enterprise network by eliminating the need for routing traffic in large networks by reducing network management costs by replacing many Layer 2 devices with a few Layer 3 devices
The message will be seen by the hosts on VLAN1 and VLAN2. The message will be seen only by the hosts connected to Switch1. The message will be seen only by the hosts connected to VLAN1 on Switch1. The message will be seen by the hosts connected to VLAN1 on Switch1 and Switch2. ¡Ì The message will only be seen by router interface e0.
