A layer 3 switch is also called?
a multilayer switch as it operates at Layer 2 and Layer 3
100
True or False
The Physical layer is only concerned with wired network connections.
False
100
What is the purpose of the vlan.dat file on a switch?
It holds the VLAN database
100
What media uses patterns of microwaves to represent bits?
Wireless
100
What is the default VLAN on a cisco switch?
VLAN 1
**NOTE** While we cannot delete VLAN 1, cisco will recommend that we assign these default features to other VLANs
200
What media uses patterns of light to represent bits?
Fiber-optic
200
What kind of media is this?
Shielded Twisted-Pair (STP) Cable
200
The physical layer standards address three functional areas. What are those areas?
1. Physical Components
2. Encoding
3. Signaling
200
What are your VTY lines for a switch?
What are your VTY lines for a router?
switch(config)#line vty 0 15 (switch)
switch(config)#line vty 0 4 (router)
200
What command do you use to verify the correct mode is assigned to the interface?
show interface switchport
or
show run
300
True or False
Passwords should be less than eight characters in length.
False

A cisco switch currently allows traffic tagged with VLANs 10 and 20 across trunk port F0/5. What is the effect of issuing a switchport trunk allowed vlan 30 command on F0/5?
It will allow ONLY VLAN 30 on F0/5
300
When VLANs are missing in a trunk interface, how do you add the missing VLANs?
1. Delete entire line (switchport access vlan ____) then retype it again
2. Use the add command (switchport access vlan add ______)
300
What are the steps to configuring a subinterface?
1. Encapsulation dot1q vlan_id [native] - This command configures the subinterface to respond to 802.1Q encapsulated traffic from the specified vlan-id. The native keyword option is only appended to set the native VLAN to something other than VLAN 1.
2. IP address ip-address subnet-mask - This command configures the IPv4 address of the subinterface. This address typically serves as the default gateway for the identified VLAN.
300
What are the bandwidth terminology?
**NOTE** There are three
Latency
Amount of time, including delays, for data to travel from one given point to another
Throughput
The measure of the transfer of bits across the media over a given period of time
Goodput
The measure of usable data transferred over a given period of time
Goodput = Throughput - traffic overhead
400
What is the purpose of setting the native VLAN separate from data VLANs?
1. The native VLAN is for the routers and switches to exchange their management information, so it should be different from data VLANs
2. The security of management frames that are carried in the native VLAN can be enhanced
3. The native VLAN is for carrying VLAN management traffic only
4. A separate VLAN should be used to carry uncommon untagged frames
4. A separate VLAN should be used to carry uncommon untagged frames
400
This method requires you to create a subinterface for each VLAN to be routed. What is this method called?
Router-on-a-Stick
400
What command is used to clear all the configurations in the privilege EXEC mode?
Erase startup-config
400
There are some simple steps that should be taken that apply to most operating systems. What are they?
1. Default usernames and passwords should be changed immediately
2. Access to system resources should be restricted to only the individuals that are authorized to use those resources
3. Any unnecessary services and applications should be turned off and uninstalled when possible
4. Often, devices shipped from the manufacturer have been sitting in a warehouse for a period of time and do not have the most up-to-date patches installed. It is important to update any software and install any security patches prior to implementation
400
It is a good practice to use the __________ command to add information about the network connected to the interface.

What do you need to start and end with for your message of the day?
a delimiter
This can be a letter, number, or special character
**DOUBLE POINTS** If you can identify what delimiter character cannot be used
500
When a cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default?
Native VLAN ID
500
What are the steps to creating trunking on a switch?
1. Create the VLAN
2. Name the VLAN
3. Assign IP address
4. Configure trunk mode
5. Allow all VLANs
6. No shut the interface

What file is stored in RAM?
startup-config = NVRAM
running-config = RAM
