Q

OSI and TCP/IP models are two tools that provide what for a IT professional?

A
  1. Provide powerful mental tools, for diagnosing problems . Understanding models enables a tech to determine quickly at what layer a problem can occur.
  2. Provide a common language to describe networks.

Q

An Oscilloscope is used to measure what?

A

Oscilloscope can measure voltage between network devices. Note: These voltages can assist in identifying the binary signals coming across the wire.

21
Q

NIC Creates and Sends, as well as receives and reads frames True or False?

A

True, The NIC is designed to create and send frames, as well as receive and read frames.

22
Q

CRC

A

(Cyclic redundancy check) error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data.

23
Q

FCS

A

(Frame Check Sequence) Uses a type of binary math called CRC (cyclic redundancy check that the receiving NIC uses to verify that the data arrived intact. (Integrity)1

24
Q

A NIC is composed of two logical parts what are they?

A

LLC and MAC

25
Q

What does the LLC part of a NIC handle

A

LLC handles multiple Network Protocols and provides flow control.

26
Q

The basic paramaters for TCP/IP were developed where?

A

(DARPA) Defense Advanced Research Projects Agency. Robert E. Kahn and Vinton Cerf worked out the robustness of the design and eventual implementation.

27
Q

IP is on what layer of the OSI Model

A

Layer 3, Network Layer

28
Q

What protocol uses a Doted Octet numbering system

A

IPv4

29
Q

What command can you use if your system shares the same IP address as another on the network?

A

Ipconfig /release, Ipconfig /renew… If these commands do not work you can check event viewer logs for DHCP error codes.

30
Q

What OSI layer are packets created?

A

Layer 3 Networking

31
Q

What does the Transport Protocol Do?

A

Breaks up the data into chunks called segments or datagrams. and gives each segment some type of sequence number.

Assembly Disassembly and initialize requests for packets that were not received in good order.

32
Q

Datagrams have sequence numbers assigned by the transport protocol. True-False

A

False - Only segments have sequence numbers assigned by the transport protocol

33
Q

Layer 4 in the OSI model represents what?

A

Transport Layer

34
Q

Layer 5 of the OSI model Represents what?

A

Session Layer

35
Q

What is the Session Layer responsible for?

A

Initiates sessions, accepts incoming sessions and opens and closes existing sessions.

36
Q

Layer 6 of the OSI model Represents what?

A

Presentation Layer

37
Q

What is the Presentation Layer responsible for?

A

Translates data from lower layers into a format usable by the application layer.

38
Q

SSL TLS are on what layer of the OSI Model

A

Both layer 5 and 6. SSL and TLS initiate at layer 5 then encrypt and decrypt at layer 6.

39
Q

Layer 7 of the OSI Model Represents what?

A

Application Layer

40
Q

What is the Application Layer responsible for?

A

Refers not to the applications itself but rather the code built into all operating systems that enable network-aware applications. All operating systems have application programing interfaces (APIs) that programers can use to make their programs network aware.

41
Q

What does a API provide

A

A standard way for programmers to enhance extend an applications capabilities.

42
Q

How many layers does the OSI model consist of?

A

7 Layers

43
Q

How many layers does the TCP/IP model consist of?

A

4 Layers Application/Transport/Internet/Link/Network Interface.

44
Q

Where does a hub send Data?

A

To all systems connected to the hub

45
Q

What Uniquely Identifies every NIC

A

MAC address

46
Q

A MAC address is known as a ________ Address

A

Physical

47
Q

A NIC sends data in discrete chunks called

A

Frames

48
Q

Which MAC address begins a frame

A

begins with the MAC address of the receiving NIC followed by the MAC address of the sending NIC, Followed by type of encapsulation data, the data, and FCS

49
Q

A frame ends with a special bit called the frame check sequence What does FCS do?

A

Verifies the data arrived correctly (Integrity)

50
Q

Which layer of the TCP/IP model controls the assembly and disassembly of data

A

Transport Layer

51
Q

Which layer of the OSI seven-layer model keeps track of a systems connections to send the right response to the right computer?

A

Session Layer keeps track of a systems connections to ensure that it sends the right response to the right computer.
