Question 1 of 17
1. Question
1 pointsA network team is comparing topologies for connecting on a shared media. Which physical topology is an example of a hybrid topology for a LAN?Correct
Incorrect
An extended star topology is an example of a hybrid topology as additional switches are interconnected with other star topologies. A partial mesh topology is a common hybrid WAN topology. The bus and ring are not hybrid topology types.

6. Question
1 pointsWhich statement describes a characteristic of the frame header fields of the data link layer?Correct
Incorrect
All data link layer protocols encapsulate the Layer 3 PDU within the data field of the frame. However, the structure of the frame and the fields that are contained in the header vary according to the protocol. Different data link layer protocols may use different fields, like priority/quality of service, logical connection control, physical link control, flow control, and congestion control.

7. Question
2 pointsWhich two factors influence the method that is used for media access control? (Choose two.)Correct
Incorrect
The media access control method used depends on the topology (how the connection between the nodes appears to the data link layer), and how the nodes share the media. The type of data generated by end devices applications, the way signals are encoded by the NICs on end devices, and even the way the IP protocol forwards the packet through the network have no influence on the choice of the method used for media access control.

8. Question
1 pointsWhat method is used to manage contention-based access on a wireless network?Correct
Incorrect
Carrier sense multiple access with collision avoidance (CSMA/CA) is used with wireless networking technology to mediate media contention. Carrier sense multiple access with collision detection (CSMA/CD) is used with wired Ethernet technology to mediate media contention. Priority ordering and token passing are not used (or not a method) for media access control.

9. Question
5 pointsMatch each type of frame field to its function. (Not all options are used.)Sort elements
- This field helps to direct the frame toward its destination.
- This field checks if the frame has been damaged during the transfer.
- This field is used by the LLC to identify the Layer 3 protocol.
- This field identifies the beginning of a frame.
- This field identifies special flow control services.
-
addressing
-
error detection
-
type
-
frame start
Correct
Incorrect
Place in the following order: error detection - This field checks if the frame has been damaged during the transfer. The second answer is not used. addressing - This field helps to direct the frame toward its destination. frame start - This field identifies the beginning of a frame. type - This field is used by the LLC to identify the Layer 3 protocol.

10. Question
1 pointsRefer to the exhibit. One end of the cable is terminated as displayed, and the other end is terminated in accordance with the T568A standard. What type of cable would be created in this manner?Correct
Incorrect
A straight-through cable can have either a T568A or T568B standard termination at one end and the same at the other end. A crossover cable has a T568A standard termination at one end and a T568B standard at the other end. A rollover cable can have either a T568A or T568B standard termination at one end, and at the other end have the same standard, but with the wires connected in reverse order. A fiber-optic cable is not terminated using RJ-45 connectors.

11. Question
1 pointsA network administrator is designing a new network infrastructure that includes both wired and wireless connectivity. Under which situation would a wireless connection be recommended?Correct
Incorrect
When the end-user devices need mobility to connect to the network, wireless is recommended. If an end-user device only has an Ethernet NIC, the user will only be able to use Ethernet cabling. If RFI is an issue, wireless is not recommended. An end-user device that requires a dedicated connection for performance would perform better with a dedicated Ethernet cable.

15. Question
1 pointsWhich statement correctly describes frame encoding?Correct
Incorrect
Frame encoding converts a stream of data bits into a predefined code that is recognized by both the sender and receiver. These codes are used for a variety of purposes, such as distinguishing data bits from control bits, and identifying the beginning and end of a frame.

16. Question
1 pointsWhat is a characteristic of a WAN hub-and-spoke topology?Correct
Incorrect
A hub-and-spoke topology is a WAN version of the star topology in which a central site interconnects branch sites using point-to-point links. A mesh topology requires that every end system be interconnected to every other system using point-to-point links. A partial mesh is a variation of this topology, where some but not all end devices are interconnected. There is no topology where all the sites have to have hub devices that are connected to a router.
