Devices on the same network logically grouped as if they were on separate networks.
you are configuring a switch so that you can manage it via PuTTY from the same network segment as the switch. on the switch, you enter the following commands: switch#config terminal switch(config)#interface vlan 1 switch(config-if)#ip address 192.168.1.10.255.255.255.0 WIll this configuration work?
NO the no shutdown command needs to be entered

you run a small network for your business that has a single router connected to the internet and a single switch. You keep sensitive documents on a computer that you would like to keep isolated.
VLAN

VLANS
you manage a network that uses a single switch. All ports within your building connect through the single switch. In the lobby of your building are three RJ-45 ports
VLANs
a router is configured with the login, no password condition for console access
access is denied
a switch running STP is classified as a backup bridge.
blocking
which of the following statements describe how VLANs affect broadcast traffic within an internetwork?
broadcast traffic is transmitted only within a VLAN Devices on the same VLAN have the same subnet address
you manage a network with a single switch. On each switch port, a hob connects multiple devices to the switch.
collisions
match each switch management method on left with its corresponding characteristics on the right. drop down
commonly sold at retail stores unmanaged switch provide port security features managed switch support VLANS managed switch provide very few configuration options unmanaged can be configured over a network connection managed can be configured over a dedicated communication channel managed
match each switch management method on left with its corresponding characteristics on the right. drop down
competes with normal network traffic for bandwidth in-band uses a dedicated communication channel out of band must be encrypted to protect communications from sniffing in band does not compete with normal network traffic for bandwidth out of band affected by network outages in band
you have three switches configured as shown in the exhibit. how can you guarantee that switch C becomes the root bridge?
configure switch C with a lower priority value.
what does the ip address dhcp command allow you to do?
configures the switch to obtain an IP address from a DHCP server

you manage a networking with two switches. you defin vlan 1 and vlan 2 on each switch. A device on the first switch in VLAN 1 needs to communicate with a device on the same switch which is in VLAN 2

which of the following features dynamically places switch ports in blocking or forwarding states?
spanning tree
which of the following solutions would you implement to eliminate loops?
spanning tree
which of the following solutions would you implement to eliminate switching loops.
spanning tree
you manage a network that uses multiple switches. You want to provide multiple paths between switches so that if one link goes down, an alternate path is available.
spanning tree
you manage a network that uses multiple switches. you wan to provide multiple paths between switches so that if on link goes down, an alternate path is available.
spanning tree
you manage a single subnet with three switches. The switches are connected to provide redundant paths between the switches which feature prevent switching loops and ensures there is only a single active path between any two switches?
spanning tree.
a virtual LAN can be created using which of the following
switch
you want to reduce collisions by creating separate collision domains and virtual LANs. Which of the following devices should you choose?
switch

switch port
which of the following statements accurately describes a vlan ID
switches append a vlan.
what problem does the spanning tree protocol prevent?
switching loops from developing when redundant paths are implemented between switches.
which of the following are true regarding using multiple VLANs on a single switch?
the number of broadcast domains increases. the number of collision domains remains the same.
while viewing the status of the interfaces on a cisco switch, you see an abnormally large number
the workstations network board is jabbering.
when configuring VLANs on a switch, what type of switch ports are members of all VLANs defined on the switch?
trunk ports
you manage a network with TWO switches, The switches are connected together through their Gigabit Ethernet uplink ports. you define VLAN 1 and WLAN2 on each switch.
trunking
you manage a single subnet with three switches. The switches are connected to provide redundant paths between the switches. to pass WLAN traffic between the switches.
trunking
