Which part of an Ethernet Frame uses a pad to increase the frame field to at least 64 bytes?

• EtherType

• Preamble

• Start of Frame Delimiter

• Data field

Which part of an Ethernet frame detects errors in the frame?

• Preamble

• Start of Frame Delimiter

• Frame Check Sequence

Which part of an Ethernet Frame describes the higher- layer protocol that is encapsulated?

• EtherType

• Preamble

  

• Start of Frame Delimiter

  

• Frame Check Sequence

Which part of an Ethernet Frame notifies the receiver to get ready for a new frame?

• Start of Frame Delimiter

• Frame Check Sequence

• Preamble

• Data field

Which data link sublayer controls the network interface through software drivers?

• MAC

• LLC

Which data link sublayer works with the upper layers to add application information for delivery of data to higher level protocols?

• MAC

• LLC

What is a function of the MAC sublayer? (Choose three.)

• controls access to the media

• checks for errors in received bits

• uses CSMA/CD or CSMA/CA to support Ethernet technology

• communicates between software at the upper layers and the device hardware at the lower layers

• allows multiple Layer 3 protocols to use the same network interface and media

When the switch forwards the frame, which statement(s) are true?

• Switch adds the source MAC address which is currently not in the MAC address table

• Frame is a broadcast frame and will be forwarded to all ports

• Frame is a unicast frame and wilt be sent to specific port only

• Frame is a unicast frame and will be flooded to all ports

• Frame is a unicast frame but it will be dropped at the switch

What are two methods for switching data between ports on a switch? (Choose two.)

• cut-off switching

• cut-through switching

• store-and-forward switching

• store-and-supply switching

• store-and-restore switching

Which switching method can be implemented using fast-forward switching or fragment-free switching?

• cut-off switching

• cut-through switching

• store -and-forward switching

• store-and-restore switching
