Network Access Chapter 4
Refer to the exhibit. What is the maximum possible throughput between the PC and the server?
128 kb/s The maximum throughput between any two nodes on a network is determined by the slowest link between those nodes.
STP
COPPER MEDIA INDUSTRIAL LOTS OF INTERFERENCE
What method is used to manage contention-based access on a wireless network?
CSMA/CA
What method is used to manage contention-based access on a wireless network?
CSMA/CA 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.
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.
In fiber optic media, the signals are represented as patterns of
LIGHT
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?
ORANGE STRIPED-ORANGE-GREEN STRIPED-BLUE-BLUE STRIPED-GREEN-BROWN STRIPED-BROWN
COAXIAL
TRADTIONALLY USED FOR TELEVISION BUT CAN BE USED IN NETWORK TO CONNECT CUSTOMER LOCATION
OPTICAL FIBER
TYPE MEDIA - HIGH TRANSMISSION SPEEDS OVER LONG DISTANCES
WIRELESS
TYPE OF MEDIA PROVIDES MOBILITY
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. (pg 208)
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 each type of frame field to its function. (Not all options are used.)
addressing error detection type frame start
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 (pg 206)
What type of cable is used to connect a workstation serial port to a Cisco router console port?
rollover (pg 183)
Which is a function of the Logical Link Control (LLC) sublayer?
to identify which network layer protocol is being used (pg 199)
What is the purpose of the OSI physical layer?
transmitting bits across the local media
