Refer to the exhibit. What would happen if the network administrator moved the network cable of Host A from interface Fa0/1 to Fa0/3 on switch SW1?

Host A remains a member of VLAN 10, because the router is routing traffic between VLANs.Host A is no longer a member of VLAN 10, because port Fa0/3 has been manually assigned to VLAN 30.Host A remains a member of VLAN 10, because the switch provides dynamic VLAN assignment for the port.Host A maintains connectivity to all members of VLAN 10, because it is connected to the same physical network.Host A is no longer a member of VLAN 10, but because port Fa0/3 was unused, it is now a member of VLAN 1.

It routes packets between different LAN segments.It uses the destination MAC address to selectively forward a frame. It performs switching and filtering based on the destination network layer address. It drops a frame whose destination MAC address is not in the MAC address table.

Refer to the exhibit. A network administrator has segmented the network into two VLANs. The connected hosts can only access resources in their own VLAN. What is the most scalable and cost effective solution to allow inter-VLAN communication in this network?

Replace S1 with a router that has one FastEthernet interface for each PC. Add a second switch and divide the PCs so that each VLAN is connected to its own switch. Configure a router with two subinterfaces on one of its FastEthernet ports and connect it to S1 using a trunk link. Connect a router to a port on S1 and assign the IP address of VLAN1 to the connecting router interface.

Refer to the exhibit. Which three options correctly describe the router configuration that is shown? (Choose three.)

An IEEE standard trunking protocol is in use.Interface Fa0/1 has been configured with subinterfaces. The shutdown command has been applied to interface Fa0/1. Interface Fa0/1.3 is mapped to the default management VLAN. The configuration is appropriate for a router-on-a-stick network design. An IP address should be applied to interface Fa0/1 for routing to occur.

72 A network administrator needs to save the configuration file currently in RAM to NVRAM before rebooting the switch. Which command should the administrator issue?

Switch1# copy startup-config flash:filenameSwitch1# copy running-config startup-configSwitch1# copy startup-config running-config Switch1# copy flash:config.txt running-config

!!!Refer to the exhibit. Switch SW2 has been newly purchased and added to the network. What configuration should be applied to SW2 so that it participates in the same VTP domain as switch SW1, receives VLAN information from SW1, and synchronizes VLAN information?

Disable VTP pruning on SW2. Configure SW2 in VTP transparent mode. Configure SW2 with the VTP domain password. Configure SW2 as a VTP server with a higher revision number.

77What are three features of router-on-a-stick, inter-VLAN routing? (Choose three.)

requires the use of VTPrequires the use of subinterfacesreduces the number of broadcast domainsaffects performance when many VLANs are usedrequires an access link between the router and at least one switchis more cost effective than other approaches to inter-VLAN routingdictates that at least two switch ports be used between the router and the switch

78While configuring a new switch, a network administrator configures the switch as an HTTP server. What benefits does this configuration provide?

This allows the switch to host web pages for the network. This allows remote VPN connections to the switch over the Internet. This is required if a web server or web farm is attached to the switch. This allows web-based configuration tools to be used with the switch.

Refer to the exhibit. What does STATIC indicate in the output that is shown?

This entry will be removed and refreshed every 300 seconds to keep it in the table. The switch learned this MAC address from the source address in a frame received on Fa0/15. The switch will only allow a device with a MAC address of 0000.c123.5432 to connect to port Fa0/15. When processing a frame, the switch does not have to perform a lookup to determine the final destination port. The switch is configured to forward traffic destined for MAC address 0000.c123.5432 will be forwarded to Fa0/15.

80Which benefit is gained by designing a network with a small network diameter?

lower latencyimproved securityincreased redundancy higher interface bandwidth

Refer to the exhibit. Both switches are interconnected via a trunk link. Host A and host B are on the default VLAN but are not able to exchange traffic. What should be done to fix the problem?

Allow all VLANs on the trunk link.

Remove the native VLAN from the trunk.

Include a router or switch with Layer 3 capabilities.

Configure the same native VLAN on both ends of the trunk.

121Company policy requires disabling the command history buffer on network devices. An administrator enters terminal no history size at the command prompt on a Cisco Catalyst switch and receives no error messages back, but the command history buffer is still available. What is the problem?

The command contained a syntax error. The Cisco IOS version does not support disabling the command history buffer. The command history can only be disabled on a router, not a switch. The size parameter reset the default buffer size but did not disable access to the buffer.

Refer to the exhibit. What does the term DYNAMIC indicate in the output that is shown?

This entry can only be removed from the MAC address table by a network administrator.

When forwarding a frame to the device with address 0060.5c5b.cd23, the switch does not have to perform a lookup to determine the final destination port.

Only the device with MAC address 0060.5c5b.cd23 will be allowed to connect to port Fa0/18.

The switch learned this MAC address from the source address in a frame received on Fa0/18.

Refer to the exhibit. Router R-West and switch S-West1 are connected via a single ethernet cable between the router interface fa0/0 and the switch interface fa0/1. The router and switch have been configured with the commands that are displayed in the exhibit. The network administrator enters the show interfaces trunk command and receives the output as shown. What is the cause of the "not-trunking" status for switch port Fa0/1?

The trunk is established, but no VLANs have been configured to use it.The router is missing the dynamic trunking protocol statements necessary to form a trunk.Because the router does not support Dynamic Trunking Protocol, the trunk has not been established.The router, the switch, or both must be configured with the dynamic desirable option for Dynamic Trunking Protocol to establish a trunk.
