What else can I help you with?
Which LAN device will direct frames onto the correct network segment by analyzing the frame's destination MAC address?
A Switch looks at the MAC address its a layer 2 device (OSI Model).
What layer of the ois model adds source and destination MAC address to frames?
in the osi model data link layer is adds source & destination mac address to frames
How do bridges keep track of whether they should forward or filter frames?
they maintain a filtering database that identifies which frames can be filtered and which should be forwarded, based on their destination MAC address.

What kind of device that links network segments and that forwards and filters frames between segments?
its a switch
Which two statements describe the operation of an access layer ethernet switch choose two?
The source MAC address within a frame is used by the switch to associate a port with that MAC address. Frames are directed by the switch from one port to another based on the destination MAC address within the frame.
How does CDP gather the neighbor devices network address information?
CDP is a Cisco proprietary protocol; it only works between Cisco devices. If CDP is enabled on a Cisco network device, it will regularly send frames with information about itself out its interfaces.CDP is a Cisco proprietary protocol; it only works between Cisco devices.

What does the format for Ethernet frames specify?
destination (physical/hardware address) Source (physical/hardware address) Start flag (start of message indicator) Recipient sender encapsulated data end of frame
What is the use of adding header and trailer to the frames?
Trailer is added at only data link layer because data link layer provides error and flow control.Header Contains address of device where frames will be send
Which device makes traffic forwarding decisions based on mac address?
A switch uses MAC address to forward frames while a router uses IP addresses.
What is a logically defined device that operates at the Data Link layer to pass frames between nodes?
virtual switch
What are frames that are not actually data frames but aberrations caused by a device misinterpreting stray voltage on the wire?
Ghosts
