Refer to the exhibit. What is the maximum possible throughput between the PC and the server?
128 kb/s
What method is used to manage contention-based access on a wireless network?
CSMA/CA
Which statement correctly describes frame encoding?
It converts bits into a predefined code in order to provide a predictable pattern to help distinguish data bits from control bits.
Fill in the blank.In fiber optic media, the signals are represented as patterns of
LIGHT Light light
What is a characteristic of a WAN hub-and-spoke topology?
The branch sites are connected to a central site through point-to-point links.
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?
The end-user device needs mobility when connecting to the network.
Which statement describes a characteristic of the frame header fields of the data link layer?
They vary depending on protocols.
Match the description with the media. (Not all options are used.)
UTP cables are used in wired office environments. Coaxial cables are used to connect cable modems and televisions. Fiber optics are used for high transmission speeds and to transfer data over long distances. STP cables are used in environments where there is a lot of interference.
Match each type of frame field to its function. (Not all options are used.)
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.
A network team is comparing topologies for connecting on a shared media. Which physical topology is an example of a hybrid topology for a LAN?
extended star
Which method of data transfer allows information to be sent and received at the same time?
full duplex
What makes fiber preferable to copper cabling for interconnecting buildings? (Choose three.)
greater distances per cable run limited susceptibility to EMI/RFI greater bandwidth potential
Which two factors influence the method that is used for media access control? (Choose two.)
how the connection between nodes appears to the data link layer how nodes share the media
What type of cable is used to connect a workstation serial port to a Cisco router console port?
rollover
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?
straight-through
Which is a function of the Logical Link Control (LLC) sublayer?
to identify which network layer protocol is being used
What is the purpose of the OSI physical layer?
transmitting bits across the local media
