Which two characteristics describe Ethernet technology? (Choose two.)
It is supported by IEEE 802.5 standards
It typically uses an average of 16 Mbps for data transfer rates
It uses unique MAC addresses to ensure that data is sent to the appropiate destination
It is supported by IEEE 802.3 standards
It uses a ring topology
What statement describes a characteristic of MAC addresses?
They are added as part of a Layer 3 PDU
They must be globally unique
They are only routable within the private network
They have a 32-bit binary value
What is the special value assigned to the first 24 bits of a multicast MAC address transporting an IPv4 packet?
01-5E-00
FF-FF-FF
01-00-5E
FF-00-5E
What will a host on an Ethernet network do if it receives a frame with a unicast destination MAC address that does not match its own MAC address?
It will strip off the data-link frame to check the destination IP address
It will forward the frame to the next host
It will discard the frame
It will remove the frame from the media
Which network device makes forwarding decisions based on the destination MAC address that is contained in the frame?
hub
router
repeater
switch
Which network device has the primary function to send data to a specific destination based on the information found in the MAC address table?
hub
router
modem
switch
Which function or operation is performed by the LLC sublayer?
It adds a header and trailer to a packet to form an OSI Layer 2 PDU
It performs data encapsulation
It is responsible for media access control
It communicates with upper protocol layers
What happens to runt frames received by a Cisco Ethernet switch?
The frame is broadcast to all other devices on the same network
The frame is dropped
The frame is sent to the default gateway
The frame is returned to the originaring network device
What addressing information is recorded by a switch to build its MAC address table?
the source Layer 3 address of outgoing packets
the source Layer 2 address of incoming frames
the destination Layer 3 address of incoming packets
the destination Layer 2 address of outgoing frames
What is auto-MDIX?
an Ethernet connector type
a type of Cisco switch
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 a specific group of hosts
an address that reaches one specific host
an address that reaches every host inside a local subnet
an address that reaches every host in the network
Which statement is true about MAC addresses?
A NIC only needs a MAC address if connected to a WAN
The first three bytes are used by the vendor assigned OUI
The ISO is responsible for MAC addresses regulations
MAC addresses are implemented by software
What are the two sizes (minimum and expected maximum) of an Ethernet frame? (Choose two.)
1024 bytes
128 bytes
56 bytes
64 bytes
1518 bytes
Which two functions or operations are performed by the MAC sublayer? (Choose two.)
It adds a header and trailer to form an OSI Layer 2 PDU
It handles communication between upper and lower layer
It is responsible for Media Access Control
It performs the function of NIC driver software
It adds control information to network protocol layer data
