Worksheet time: 8mins
What is a primary role of the Physical layer in transmitting data on the network?
provide physical addressing to the devices
create the signals that represent the bits in each frame on to the media
determine the path packets take through the network
Which two statements describe the services provided by the data link layer? (Choose two.)
It manages the access of frames to the network media.
It packages various Layer 3 PDUs into a frame format that is compatible with the network interface.
It defines the end-to-end delivery addressing scheme.
It provides reliable delivery through link establishment and flow control.
A network team is comparing physical WAN topologies for connecting remote sites to a headquarters building. Which topology provides high availability and connects some, but not all, remote sites?
partial mesh
mesh
hub and spoke
point-to-point
During the encapsulation process, what occurs at the data link layer for a PC connected to an Ethernet network?
The physical address is added.
An IP address is added.
The logical address is added.
The process port number is added.
Which switching method has the lowest level of latency?
cut-through
fast-forward
store-and-forward
fragment-free
What are two actions performed by a Cisco switch? (Choose two.)
using the source MAC addresses of frames to build and maintain a MAC address table
utilizing the MAC address table to forward frames via the destination MAC address
building a routing table that is based on the first IP address in the frame header
forwarding frames with unknown destination IP addresses to the default gateway
Which type of UTP cable is used to connect a PC to a switch port?
straight-through
console
rollover
crossover
What action will occur if a host receives a frame with a destination MAC address of FF:FF:FF:FF:FF:FF?
The host returns the frame to the switch.
The host will process the frame.
The host replies to the switch with its own IP address.
The host forwards the frame to all other hosts.
What OSI physical layer term describes the physical medium which uses electrical pulses?
copper cable
fiber-optic cable
goodput
What OSI physical layer term describes the amount of time, including delays, for data to travel from one point to another?
latency
bandwidth
throughput
What OSI physical layer term describes the measure of the transfer of bits across a medium over a given period of time?
bandwidth
throughput
latency
goodput
What OSI physical layer term describes the capacity at which a medium can carry data?
bandwidth
IEEE
EIA/TIA
Which is a multicast MAC address?
01-00-5E-00-00-03
FF-FF-FF-FF-FF-FF
5C-26-0A-4B-19-3E
00-26-0F-4B-00-3E
What is the purpose of the FCS field in a frame?
to determine if errors occurred in the transmission and reception
to obtain the MAC address of the sending node
to verify the logical address of the sending node
Which statement is true about the CSMA/CD access method that is used in Ethernet?
All network devices must listen before transmitting.
When a device hears a carrier signal and transmits, a collision cannot occur.
A jamming signal causes only devices that caused the collision to execute a backoff algorithm.
