SwitchB(config)#*ip default-gateway* 192.168.8.254 SwitchB(config)#interface vlan 1 SwitchB(config-if)#ip address 192.168.8.252 255.255.255.0 SwitchB(config-if)#no shutdown (The Management Workstation is in a different subnet from the SwitchB. For inter-subnetwork communication to occur, *you must configure at least one default gateway.* This default gateway is used to forward traffic originating from the switch only, not to forward traffic sent by devices connected to the switch.)

A technician has installed SwitchB and needs to configure it for remote access from the management workstation connected to SwitchA. Which set of commands is required to accomplish this task?

the interface has an access port to allow the voice VLAN ID.

Configuration of which option is required on a Cisco switch for the Cisco IP phone to work?

trunk port

On which type of port can switches *interconnect* for *multi-VLAN* communication?

Check the *duplex mode for SwitchA's fa0/2 port.*

Refer to the exhibit. Given this output for SwitchC, what should the network administrator's next action be?

Switch-Cisco*!* The "!" is a special character which is not allowed in the hostname of Cisco device.

Which option is an *INVALID* hostname for a switch? 5witch-Cisco Switch-Cisco*!* 5witchCisc0 SwitchCisc0

If the destination MAC address is unknown, *the frame is flooded to every port* that is configured in the same VLAN except on the port that it was received on.

Which statement about *unicast* frame forwarding on a switch is true?

They *drop* packets with 802.1Q tags.

Which statement about switch access ports is true?

*cut-through* switching

Which switching method *duplicates the first six bytes of a frame* before making a switching decision?

Microsegmentation, decreases, collisions root bridge, forwarding, broadcast VLANS, broadcast

Which three statements accurately describe *layer 2 Ethernet switches?* - ______________________ ___________________ the number of network_______________ on the network. - In a properly functioning network with redundant switch paths, each switched segment will contain one _________ __________ with all its ports in the __________________ state. All other switches in that ___________________ domain will only have one root. - Establishing ____________ increases the number of __________________ domains.

MAC address Port numbers

Which two types of information are held in the MAC address table?

ping

Which utility can you use to determine whether a switch can send echo requests and replies?

It configures an *inactive switch virtual interface.* (In the configuration above, the "no shutdown" command was missing so interface Vlan 1 is still inactive.)

Refer to the exhibit. What is the effect of the given configuration? Switch#configuration terminal Switch#interface VLAN 1 Switch(config-if)#ip address 192.168.2.2 255.255.255.0 Switch(config-if)#end

*Remote access management* of this switch *will not be possible* without configuration change. (From the output we notice that the administrator has just shut down Interface Vlan1, which is the default VLAN so no one can access it remotely (like telnet)

Refer to the exhibit. Which of these statements correctly describes the state of the switch once the boot process has been completed?

Switch-1 will *flood* the data out all of its ports except the port from which the data originated. (*MAC has not been learned*, so Switch-1 will broadcast the frame out all of its ports, except originating port.)

Switch-1 needs to send data to a host with a MAC address of 00b0.d056.efa4. What will Switch-1 do with this data?

Switch1 (config)# *ip default-gateway* 192.168.24.1

The network administrator *cannot connect to Switch1 over a Telnet session, although the hosts attached to Switch1 can ping the interface Fa0/0 of the router.* Given the information in the graphic and assuming that the router and Switch2 are configured properly, which of the following commands should be issues on Switch1 to correct this problem?

The switch needs an appropriate *default gateway* assigned.

The network administrator normally establishes a Telnet session with the switch from host A. The administrator's attempt to establish a connection via Telnet to the switch from host B fails, but pings from host B to other two hosts are successful. What is the issue?

The two hosts are in the *same broadcast domain.*

Two hosts are attached to a switch with the default configuration. Which statement about the configuration is *true?*

- The number of *collision* domains would *increase* - The number of *broadcast domains* would *remain the same*

What two results would occur if the hub were to be replaced with a switch that is configured with one Ethernet VLAN?

Dynamic

What type of MAC address is *aged automatically* by the switch?

switch-mdf-c1*(config)#hostname* switch-mdf1

Which command can you use to set the hostname on a switch?

CSMA/CD (CSMA/CD is used with devices operating in half-duplex mode only.)

Which feature allows a device to use a switch port that is configured for *half-duplex to access the network?*

both, full duplex both, auto negotiate both, half duplex

Which of the three options are switchbox configurations that can always avoid duplex mismatch errors between two switches? - Set ________ sides of the connection to _______ ___________ - Set ________ sides of the connection to _______ ___________ - Set _______ sides of the connection to ________ ___________
