Multiple Choice Questions

This type of media provides most mobility options.
  • Wireless is..........?
  • What does addressing do?
  • Optical fiber........?
  • STP is..........?
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.

The physical layer is responsible for transmitting the actual signals across the physical media as bits. Exchanging frames, controlling media access, and performing error detection are all functions of the data link layer.

  • What is the purpose of the OSI physical layer?
The maximum throughput between any two nodes on a network is determined by the slowest link between those nodes.

  • Refer to the exhibit. What is the maximum possible throughput between the PC and the server?
  • Which two factors influence the method is used for media access control?
  • What type of cable is used to connect a workstation serial port to a Cisco router console port?
UTP cable wire pairs can be terminated in different configurations for use in different applications. To use a UTP cable for consoling into a Cisco router from a PC serial port, it must be terminated as a rollover or console cable.
  • What method is used to manage contention-based access on a wireless network?
  • Which statement describes a characteristic of the frame header fields of the data link layer?
  • What type of cable is used to connect a workstation serial port to a Cisco router console port?
  • Which two factors influence the method is used for media access control?
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.

  • Refer 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?
  • A network administrator is designing a new network infrastructure that includes both wired and wireless connectivity. Under which situation would a wireless connection be recommended?
  • What method is used to manage contention-based access on a wireless network?
light
  • In fiber optic media, the signals are represented as patterns of _______?
  • Refer to the exhibit. What is the maximum possible throughput between the PC and the server?
  • What method is used to manage contention-based access on a wireless network?
  • Which method of data transfer allows information to be sent and received at the same time?
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.
  • Which statement correctly describes frame encoding?
  • What is the purpose of the OSI physical layer?
  • Which statement describes a characteristic of the frame header fields of the data link layer?
  • Which is a function of the Logical Link Control (LLC) sublayer?
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.

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.

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.

Used by the LLC to identify the Layer 3 protocol.
  • What does type do?
  • What does error detection do?
  • Wireless is..........?
  • What does addressing do?
Defining the media access processes that are performed by the hardware and providing data link layer addressing are functions of the MAC sublayer. The data link layer accepts Layer 3 packets and packages them into data units that are called frames.
