What OSI second layer network device can connect dissimilar networks, such as Ethernet and Token Ring?
a. router b. gateway c. bridge d. switch e. hub |
c.
A bridge operates on the Data Link layer and can connect dissimilar networks. router = directs packets from one network to another gateway = either a special router or operates on multiple layers of the OSI model switch = connects only similar types of media hub = can only regenerate the same signal to ports on same type of network |

Which IEEE subcommittee defines Token Rings?
a. 802.1 b. 802.2 c. 802.3 d. 802.4 e. 802.5 |
e.
802.5 defines Token Rings. |
|
|
What is the upper sub-layer of layer two of the OSI model?
a. media access control b. logical link layer c. physical layer d. network layer e. transport layer |
b.
The Logical Link Layer is the upper sub-layer of the OSI Data Link layer. |
|

Which of the following is a correct example of a MAC address?
a. 256.2.150.4 b. 155.210.17.9 c. 255.255.255.0 d. 5G:43:B2:41:34:E2 e. 2F:94:5B:2C:34:2E |
e.
2F:94:5B:2C:34:2E because it contains twelve properly formatted hexidecimal numbers. (d is invalid because is not a exadecimal number) |

Match:
a. 802.1 b. 802.2 c. 802.3 d. 802.4 e. 802.5 _____ Token Bus _____ Internetworking _____ Logical Link Control _____ Token Rings _____ Carrier Sense Multiple Access/Collision Detection |
802.4 = Token Bus
802.1 = Internetworking 802.2 = Logical Link Control 802.5 = Token Rings 802.3 = Carrier Sense Multiple Access/Collision Detection |
|
|
Device that operates on the Data Link layer of the OSI model and extends a network to make two separate segments appear as if they are one.
|
bridge
|
|
|
True or False
Different media communications, such as Ethernet and Token Ring, can be connected using a bridge. |
true

Name the organization that determines specifications on many types of electrical systems.
|
IEEE
(Institure of Electrical and Electronics Engineers) |
|
|
Name the 12-digit hexadecimal number that defines a network node on the Data Link layer of the OSI model.
|
MAC address
(Media Access Control) |
|
|
What are the two sublayers of the Data Link layer?
|
Logical Link Control (LLC)sublayer
Media Access Control (MAC)sublayer |
|
|
Which Data Link sublayer sublayer multiplexes protocols running atop the data link layer, and optionally provides flow control, acknowledgment, and error recovery?
|
LLC sublayer
(Logical Link Control) |
|
|
Which protocol can be used with all of the IEEE 802 MAC layers, such as Ethernet, token ring, IEEE 802.11, etc., as well as with some non-802 MAC layers such as FDDI?
|
802.2
