Hubs can have their ports be configured with VLANs
Using hubs is costly with regard to bandwidth availability.
Switches can not forward broadcasts.
Switches are more efficient than hubs in processing frames.
Switches increase the number of collision domains in the network.
Bridges are faster than switches because they have fewer ports.
A switch is a multiport bridge,
Bridges and switches learn MAC addresses by examining the source MAC address of each frame received.
A bridge will forward a broadcast but a switch will not.
Bridges and switches increase the size of a collision domain.
Collision prevention on a LAN segment.
Broadcast domain enlargement
A network adapter card
The microsegmentation of broadcast domains
Bridging between LAN segments
VLAN membership assignment
Switches are primarily software based while bridges are hardware based.
Switches usually have a higher number of ports than most bridges.
Bridges are frequently faster than switches.
Both bridges and switches forward Layer 2 broadcasts.
Both bridges and switches make forwarding decisions based on Layer 2 addresses.
A. Switches take less time to process frames than hubs take
B. Hubs can filter frames
C. Switches do not forward broadcasts
D. Switches increase the number of collision domains in the network
E. Using hubs can increase the amount of bandwidth available to hosts
A CSU/DSU terminates a digital local loop.
A router is commonly considered a DCE device.
A modem terminates an analog local loop.
A router is commonly considered a DTE device.
A modem terminates a digital local loop.
Allowing simultaneous frame transmissions
Increasing the size of broadcast domains

Decreasing the number of collision domains
To determine the status of network services on a remote device
To obtain the IP Address of a connected device in order to telnet to the device
To verify the type of cable interconnecting two devices
To verify Layer 2 connectivity between two devices when Layer 3 fails
To obtain VLAN information from directly connected switches
Neighbor traffic data
Fiber optic cable
None of the above
A crossover cable connecting the switches
A backbone switch connecting the switches with either fiber optic or straight-through cables
A straight-through cable connecting the switches
A CSU/DSU connected to the switches with straight-through cables

The data link layer
The application layer
The access layer
The session layer
The network layer
The presentation layer translates bits into voltages for transmission across the physical link.
The transport layer divides a data stream into segments and adds reliability and flow control information.
Packets are created when the network layer adds Layer 3 addresses and control information to a segment.
The data link layer adds physical source and destination addresses and an FCS to the segment.
Packets are created when the network layer encapsulates a frame with source and destination host addresses and protocol-related control information.
The sequence number in the TCP header
The Start Frame Delimiter in the 802.3 Preamble
The TTL in the IP header
The acknowledgement number in the segment header
The frame check sequence in the Ethernet frame trailer
The destination port number in a segment header will have a value of 80
The destination IP address of a packet will be the IP address of the E0 interface of the Certkiller 1 router
The destination IP address of a packet will be the IP address of the network interface of the Certkiller II server
The destination address of a frame will be the MAC address of the E0 interface of Certkiller 1 router
