A network administrator is troubleshooting connectivity issues on a server. Using a tester, the administrator notices that the signals generated by the server NIC are distorted and not usable. In which layer of the OSI model is the error categorized?
presentation layer
network layer
physical layer
date link layer
What type of cable is used to connect a workstation serial port to a Cisco router console port?
crossover
rollover
straight-through
coaxial
Why are two strands of fiber used for a single fiber optic connection?
The two strands allow the data to travel for longer distances without degrading
they prevent crosstalk from causing interference on the connection
They increase the speed at which the data can travel
They allow for full-duplex connectivity
Which procedure is used to reduce the effect of crosstalk in copper cables?
requiring proper grounding connectinons
Twisting opposing circuit wire pairs together
wrapping the bundle of wires with metallic shielding
Avoiding sharp bends during installation
What is the definition of bandwidth?
the speed of bits across the media over a given period of time
the amount of data that can flow from one place to another in a given amount of time
the speed at which bits travel on the network
the measure of usable data transferred over a given period of time

93
What is the binary representation of 0xCA?
10111010
11010101

What is true concerning physical and logical topologies?
The logical topology is always the same as the physical topology
Physical topologies are concerned with how a network transfers frames
Physical topologies display the IP addressing scheme of each network.
Logical topologies refer to how a network transfers data between devices
Which statement describes the half-duplex mode of data transmission?
Data that is transmitted over the network can only flow in one direction.
Data that is transmitted over the network flows in one direction at a time.
Data that is transmitted over the network flows in one direction to many different destinations simultaneously.
Data that is transmitted over the network flows in both directions at the same time.
What are the two sublayers of the OSI model data link layer? (Choose two.)
internet
physical
LLC
transport
MAC
What type of physical topology can be created by connecting all Ethernet cables to a central device?
Bus
Ring
Star
Mesh
Which is a function of the Logical Link Control (LLC) sublayer?
to define the media access process that are performed by the hardware
to provide data link layer addressing
to identify which network layer protocol is being used
to accept segments and package them into date units that are called packets
Which network device makes forwarding decisions based on the destination MAC address that is contained in the frame?
hub
repeater
switch
router
Which network device has the primary function to send data to a specific destination based on the information found in the MAC address table?
switch
router
hub
modem
What happens to runt frames received by a Cisco Ethernet switch?
The frame is dropped
the frame is returned to the originating network device
the frame is broadcast to all other deices on the same network
the frame is sent to the default gateway
What is auto-MDIX?
a type of Cisco switch
an ethernet connector type
a feature to automatically determine speed and duplex
a feature that detects ethernet cable type
What type of address is 01-00-5E-0A-00-02?
an address that reaches every host inside a local subnet
an address that reaches one specific host
an address that reaches every host in the network
an address that reaches a specific group of hosts
