18
Q

Provides a method for the receiving device to determine if the frame experienced transmission errors (HDLC).

A

Frame Check Sequence (FCS)

19
Q

Protocol that allows users to connect to IP networks using modems or dedicated leased lines.

A

Point-to-Point protocol

20
Q

What are the fields of a PPP frame>

A
  • Flag
  • Addresss
  • Control
  • Protocol ID
  • Payload
  • FCS
21
Q

A packet-switched technology that emerged in the early 1990s and provides for dynamic-bandwidth and congestion control features.

A

Frame Relay

22
Q

Transmitted by source (sending) terminal requesting the destination (receiving) terminal slow down its request for data.

A

Forward Explicit Congestion Notification (FECN)

23
Q

Transmitted by destination terminal requesting the source terminal send data more quickly.

A

Backwards Explicit Congestion Notification (BECN)

24
Q

Providing a guaranteed minimum bandwidth for each user.

A

Committed information rate (CIR)

25
Q

What is a frame relay frame composed of?

A

Flags, address field, data, payload, FCS field

26
Q

One of the oldest packet-switched services available, developed before the OSI model. Uses a reliable Data Link Layer protocol for error checking which adds overhead to the data slowing down transmission speeds.

A

X.25

27
Q

Used to perform buffering of data, packet assembly, and packet disassembly, when network devices are too simple to implement full X.25 functionality.

A

Packet assembler/disassembler

28
Q

Allows routers to label data and use specific connections and paths.

A

Multi-Protocol Label Switching (MPLS)

29
Q

An MPLS router that performs routing based only on the label.

A

Label Switch Routers (LSRs)

30
Q

A router that operates at the edge of an MPLS network and acts as the entry and exit points for the network.

A

Label Edge Routers (LERs)

31
Q

An error reporting mechanism for the IP protocol. It sends error reports back to the originator of the datagram if there is a problem along the transmission path.

A

Internet Control Message Protocol (ICMP) (Network Layer)

32
Q

Utiltity that uses the ICMP messages Echo (request) and Echo reply to request a ersponse from a remote host to verify if it is available for communication.

A

ping

33
Q

Utility that uses ICMP to send messages and then uses the returning ICMP Time Exceeded (Time to Live) error messages to identify routers from source to destination.

A

traceroute

34
Q

A protocol used with IP multicast.

A

Internet Group Management Protocol (IGMP)

35
Q

Protocols that handle data delivery between computers.

A

Transport Layer Protocols

36
Q

A reliable, connection-oriented Transport Layer protocol that accepts data of any length from upper-layer protocols and breaks them into segments.

A

Transmission Control Protocol (TCP)

37
Q

TCP uses a process known as the ________ to establish a logical connection prior to the transmission of data, whcih is maintained throughout the entire communications session.

A

Three-way handshake

38
Q

What are the three steps of the three-way handshake?

A
  1. SYN
  2. SYN/ACK
  3. ACK
39
Q

An unreliable, connectionless protocol that does not guarantee data tranmission.

A

User Datagram Protocol (UDP)

40
Q

What are the two most common tools used with ICMP?

A

ping and traceroute

41
Q

Which WAN protocol deals with Supervisory and Unnumbered frames?

A

HDLC

42
Q

What type of ICMP error messages are user with traceroute?

A

Time Exceeded

43
Q

Which protocol allows nodes to join multicast groups?

A

IGMP
