63

Which of the following are data link layer protocols? (select all that apply)

802.11 Ethernet PPP

Which statement describes an extended star topology?

End devices connect to a central intermediate device, which in turn connects to other central intermediate devices.

What are three ways that media access control is used in networking? (Choose all that apply.)

Ethernet utilizes CSMA/CD. Media access control provides placement of data frames onto the media. Data link layer protocols define the rules for access to different media.

Which LAN topology is a hybrid topology?

Extended Star

Which two functions are performed at the MAC sublayer of the OSI data link layer?

Implements a trailer to detect transmission errors. Controls the NIC responsible for sending and receiving data on the physical medium.

Which two statements describe features or functions of the logical link control sub layer in Ethernet standards? (Choose two.)

Logical link control is implemented in software The data link layer uses LLC to communicate with the upper layers of the protocol suite.

Which topology displays networking device layer IP addresses?

Logical topology

Fill in the blank. The Ethernet _____ sublayer is responsible for communicating directly with the physical layer.

MAC

The media access control method used depends on which two criteria?

Media sharing Topology

Which statement is true about MAC addresses?

The first three bytes are used by the vendor assigned OUI.

During the encapsulation process at Data Link layer, what occurs at the data link layer for a PC connected to an Ethernet network?

The physical address is added.

What statement describes a characteristic of MAC addresses?

They must be globally unique.

Which statement describes a characteristic of the frame header fields of the data link layer?

They vary depending on protocols.

What type of communication rule would best describe CSMA/CD?

access method

What type of address is 01-00-5E-0A-00-02?
