To connect a switch to a LAN, you must use some sort of media. The most common LAN media is Ethernet. Ethernet is not just a type of cable or protocol. It is a network standard published by the Institute of Electrical and Electronics Engineers

Q

A flexible, transparent fiber that is made of very pure glass (silica) and is not much larger than a human hair. It acts as a waveguide, or “light pipe,” to transmit light between the two ends of the fiber.

A

optical fiber

18
Q

Is used for shorter distances at a lower bit rate than SMF

A

MMF (Multi-Mode Fiber)

19
Q

For long-distance communications,

A

SMF (Single-Mode Fiber)

20
Q

Is for enterprise equipment and is commonly used on small form-factor pluggable (SFP) modules.

A

Local connector (LC)

21
Q

Is for enterprise equipment.

A

Subscriber connector (SC)

22
Q

Is for patch panels (for their durability)

A

Straight tip (ST)

23
Q

Is for patch panels and is used by service providers.

A

Fiber-optic connector (FC)

24
Q

Connector is a two-fiber connector (transmit and receive), has a form factor and is used for enterprise equipment.

A

Mechanical Transfer Registered Jack (MT-RJ)

25
Q

This field consists of 8 bytes of alternating 1s and 0s that are used to synchronize the signals of the communicating computers.

A

Preamble

26
Q

The DA field contains the MAC address of the network interface card (NIC) on the local network to which the frame is being sent.

A

Destination Address (DA)

27
Q

The SA field contains the MAC address of the NIC of the sending computer.

A

Source Address (SA)

28
Q

This field contains a code that identifies the network layer protocol.

A

Type

29
Q

This field contains the network layer data. If the data is shorter than the minimum length of 46 bytes, a string of extraneous bits is used to pad the field. This field is also known as “data and padding”.

A

Payload

30
Q

The frame check sequence (FCS) field includes a checking mechanism to ensure that the frame of data has been transmitted without corruption. The checking mechanism that is being used is the cyclic redundancy check (CRC).

A

FCS (frame check sequence)

31
Q

Communication in which a frame is sent from one host and is addressed to one specific destination. In a unicast transmission, there is only one sender and one receiver. Unicast transmission is the predominant form of transmission on LANs and within the Internet.

A

Unicast

32
Q

Communication in which a frame is sent from one address to all other addresses. In this case, there is only one sender, but the information is sent to all the connected receivers. Broadcast transmission is used for sending the same message to all devices on the LAN.

A

Broadcast

33
Q

Communication in which information is sent to a specific group of devices or clients. Unlike broadcast transmission, in multicast transmission, clients must be members of a multicast group to receive the information.

A

Multicast

34
Q

The OUI identifies the manufacturer of the NIC. The IEEE regulates the assignment of OUI numbers. Within the OUI, there are 2 bits that have meaning only when used in the destination address field:

A

24-bit OUI

35
Q

When the least significant bit in the first octet of the MAC address is 1, it indicates to the receiving interface that the frame is destined for all (broadcast) or a group of (multicast) end stations on the LAN segment. This bit is referred to as the Individual/Group (I/G) address bit.

A

Broadcast or multicast bit

36
Q

The second least significant bit of the first octet of the MAC address is referred as a universally or locally (U/L) administered address bit. Normally, the combination of the OUI and a 24-bit station address is universally unique. However, if the address is modified locally, this bit should be set to 1.

A

Locally administered address bit

37
Q

This portion uniquely identifies the Ethernet hardware.

A

24-bit, vendor-assigned, end-station address

38
Q

The MAC address table is stored in the

A

content-addressable memory (CAM)

39
Q

The switch examines the destination MAC address and if it is unicast, performs one of the following actions depending whether the MAC address is present in the MAC address table:

  • No: Forwards the frame out all ports except the incoming port (referred to as unknown unicast).
  • Yes: Forwards the frame out of the port from which that MAC address was learned previously.
A

Unicast frames forwarding

40
Q

The switch examines the destination MAC address and if it is broadcast or multicast, forwards the frame out all ports except the incoming port (unless using Internet Group Management Protocol (IGMP) with multicast, in which case it will only send the frame to specific ports).

A

Broadcast or multicast frames forwarding
