IPX/SPX is a protocol suite developed by Novell that was widely used on older NetWare networks. However, newer versions of NetWare have shifted to using TCP/IP as the preferred protocol. Microsoft refers to IPX/SPX as NWLink (NetWare Link).
2.
________ is a transport protocol developed by IBM but adopted by Microsoft for use in earlier versions of Windows and DOS. This protocol is commonly found in smaller networks due to the fact that it is a nonroutable protocol.
Correct Answer
NetBEUI
Explanation
NetBEUI is a transport protocol that was initially developed by IBM but later adopted by Microsoft for use in earlier versions of Windows and DOS. It is commonly found in smaller networks because it is a nonroutable protocol, meaning it cannot be used to communicate across different networks. NetBEUI is known for its simplicity and efficiency, making it suitable for smaller networks where routing capabilities are not required.
3.
NetBEUI has a close friend, _______, with which it works closely when communicating with systems on the network. It is an application programming interface (API) that is used to make network calls to remote systems. When you install NetBEUI, it includes this protocol, and it relies on it for session management functionality. Also, it is nonroutable but may be installed with other routable protocols such as IPX/SPX or TCP/IP to allow it's traffic to travel across networks.
Correct Answer
NetBIOS
Explanation
NetBEUI has a close friend, NetBIOS, with which it works closely when communicating with systems on the network. NetBIOS is an application programming interface (API) that is used to make network calls to remote systems. When NetBEUI is installed, it includes the NetBIOS protocol and relies on it for session management functionality. NetBIOS is nonroutable but may be installed with other routable protocols such as IPX/SPX or TCP/IP to allow its traffic to travel across networks.
4.
This protocol has two communication modes, Session mode and Datagram mode.
Correct Answer
NetBIOS
Explanation
NetBIOS is a protocol that provides services for communication between computers on a local area network. It supports two communication modes, Session mode and Datagram mode. In Session mode, a connection is established between the communicating devices, allowing for reliable and ordered data transmission. Datagram mode, on the other hand, does not require a connection and allows for faster but less reliable transmission of data. NetBIOS is commonly used for file sharing, printer sharing, and other network services.
5.
This communication mode is used for connection-oriented communication in which NetBIOS would be responsible for establishing a session with the target system, monitoring the session to detect any errors in transmission, and then recovering from those errors by retransmitting any data that went missing or was corrupt.
Correct Answer
Session
Session mode
Explanation
Session mode is the correct answer because it refers to the communication mode used for connection-oriented communication. In this mode, NetBIOS is responsible for establishing a session with the target system, monitoring the session for errors, and recovering from those errors by retransmitting any missing or corrupt data.
6.
This communication mode Is used for connectionless communication in which a session is not needed. It also is used for any broadcast by NetBIOS. It does not support error detection and correction services, which are therefore the responsibility of the application using NetBIOS.
Correct Answer
Datagram
Datagram mode
Explanation
Datagram mode is a communication mode that is used for connectionless communication, meaning that a session is not required. It is also used for any broadcast by NetBIOS. In this mode, error detection and correction services are not supported, so the responsibility of ensuring data integrity falls on the application using NetBIOS. Therefore, the correct answer is Datagram mode.
7.
______ is a routable protocol that was built by Novell and used in older version of Netware.
Correct Answer
IPX/SPX
Explanation
IPX/SPX is a routable protocol developed by Novell and used in older versions of Netware. It stands for Internetwork Packet Exchange/Sequenced Packet Exchange. IPX/SPX was primarily used for communication between computers in a local area network (LAN). It provided reliable and efficient data transmission by breaking data into smaller packets and ensuring their sequential delivery. However, with the emergence of TCP/IP as the dominant networking protocol, IPX/SPX has become less common and has been largely replaced by TCP/IP in modern networks.
8.
This protocol is responsible for the routing of packets, it is also a connectionless, unreliable transport.
Correct Answer
A. IPX
Explanation
IPX (Internetwork Packet Exchange) is the correct answer. IPX is a network layer protocol that is responsible for routing packets in a network. It is a connectionless and unreliable transport protocol, meaning it does not establish a connection before transmitting data and does not guarantee the delivery of packets. IPX was commonly used in Novell NetWare networks. SPX (Sequenced Packet Exchange) is a transport layer protocol that works in conjunction with IPX to provide reliable delivery of packets. However, the given statement does not mention SPX, making IPX the appropriate answer.
9.
This protocol is responsible for reliable delivery. It is a connection-oriented protocol that will ensure that packets that are not received at the destination are retransimitted on the wire.
Correct Answer
B. SPX
Explanation
SPX (Sequenced Packet Exchange) is a protocol that provides reliable delivery of packets. It is a connection-oriented protocol, meaning that it establishes a connection between the sender and receiver before transmitting data. SPX ensures reliable delivery by retransmitting any packets that are not received at the destination. Therefore, SPX fits the description given in the question, making it the correct answer.
10.
This protocol is a routable protocol that is used primarily in Macintosh environments to connect multiple systems together in a network environment. It was implemented in two phases, known as phase 1 and phase 2, with the second phase being more popular today.
Correct Answer
AppleTalk
Apple Talk
Explanation
AppleTalk is a routable protocol primarily used in Macintosh environments to connect multiple systems together in a network. It was implemented in two phases, phase 1 and phase 2, with the second phase being more widely used today.
11.
This phase of the AppleTalk protocol was designed for small workgroup environments and therefore supports a much smaller number of nodes on the network. It supports nonextended networks; each network segment is allowed to be assigned only a single network number, and only one zone is allowed in a nonextended network. A zone is a logical grouping of nodes—the network administrator will assign nodes to a particular zone.
Correct Answer
A. 1
Explanation
The correct answer is 1 because it accurately describes the phase of the AppleTalk protocol that was designed for small workgroup environments. This phase supports a smaller number of nodes on the network and allows only one network number to be assigned to each network segment. Additionally, it only allows for one zone in a nonextended network, which is a logical grouping of nodes that the network administrator assigns.
12.
This phase was designed for larger networks and supports more than 200 hosts on the network.It supports extended networks, thereby allowing one network segment to be assigned multiple network numbers and allowing for multiple zones on that network segment. Each node is part of a single zone on an extended network.
Correct Answer
B. 2
13.
This protocol is unsecure and requires configuration when installing. However, it can be used to connect dissimilar environments together.
Correct Answer
TCP/IP
Explanation
TCP/IP is a widely used network protocol suite that allows communication between different devices and networks. It is considered unsecure because it does not provide built-in encryption or authentication mechanisms. However, it can be configured to enhance security by implementing additional protocols or using encryption technologies. TCP/IP is also known for its ability to connect dissimilar environments, enabling communication between different operating systems and network architectures.
14.
This is the only protocol that is nonroutable.
Correct Answer
A. NetBEUI
Explanation
NetBEUI is the correct answer because it is the only protocol among the options that is nonroutable. This means that it cannot be used to communicate across different networks or subnets. NetBEUI is primarily designed for small local area networks (LANs) and does not have the capability to route data between different networks. In contrast, IPX/SPX, AppleTalk, and TCP/IP are all routable protocols that can be used for communication between different networks.

TCP is an example of a transport protocol responsible for:
Correct Answer
A. Reliable delivery
Explanation
TCP (Transmission Control Protocol) is a transport protocol that ensures reliable delivery of data over a network. It achieves this by using various mechanisms such as acknowledgement, retransmission, and flow control. TCP guarantees that data packets are delivered in the correct order and without errors, making it suitable for applications that require accurate and error-free transmission, such as web browsing, email, and file transfer.
18.
UDP is an example of a transport protocol responsible for:
Correct Answer
B. Unreliable delivery
Explanation
UDP (User Datagram Protocol) is a transport protocol that provides unreliable delivery of data. Unlike TCP, UDP does not guarantee that the data will be delivered successfully or in the correct order. It is a connectionless protocol that does not establish a dedicated connection before sending data. UDP is commonly used for applications that prioritize speed and efficiency over reliability, such as streaming media, online gaming, and DNS. Since it does not have the overhead of error checking and retransmission, UDP can deliver data with lower latency, but it also means that data may be lost or arrive out of order.
19.
A reliable dialog between two computers is called a ________________.
Correct Answer
session
Explanation
A session is just like a telephone call. You set up a telephone call by dialing (handshaking), speak to the other person (exchange data), say “Goodbye,” and hang up when finished.
20.
_____________ communication is a form of communication in which the sending system does not “introduce” itself—it just fires the data off. Also, the destination computer does not notify the source when the information is received. This type of communication can be unreliable because there is no notification to guarantee delivery. It can be faster than the other type of communication because the overhead of managing the session is not there, and after the information is sent, there is no second step to ensure proper receipt of information.
Correct Answer
Connectionless
Explanation
Connectionless communication is a form of communication where the sending system does not identify itself and simply transmits the data without any acknowledgment from the destination computer. This type of communication can be unreliable as there is no guarantee of delivery. However, it can be faster than connection-oriented communication because there is no overhead of managing the session and no need for a second step to ensure proper receipt of information. Therefore, the correct answer is "Connectionless."
21.
This type of communication means data is sent without acknowledgment of receipt.
Correct Answer
A. Unreliable
Explanation
This type of communication, known as unreliable, refers to the transmission of data without any acknowledgment of receipt. In this type of communication, there is no guarantee that the data will reach its intended destination or that it will be received correctly. It is called unreliable because there is a possibility of data loss or errors during transmission.
22.
This type of communication means that a session is not established before transmitting.
Correct Answer
B. Connectionless
Explanation
Connectionless communication refers to a mode of communication where a session is not established before transmitting data. In this type of communication, each packet is treated independently and does not require a dedicated connection or acknowledgment from the receiver. This approach allows for faster transmission and reduced overhead, making it suitable for applications where reliability is not a primary concern, such as streaming media or real-time communication.
23.
This protocol runs at layer 3 and 4 but the Network+ exam only considers layer 3 as the correct answer. It is not connection oriented. It is routable. It is an unreliable communication.
Correct Answer
A. IPX
Explanation
Remember, unreliable means data is sent without acknowledgment of receipt, and connectionless means that a session is not established before transmitting.
IPX = Internetwork Packet Exchange
24.
This protocol is a transport protocol used by IPX for connection-oriented communication. It is responsible for breaking the message into manageable packets and ensuring the data reaches the destination. It runs at layer 4.
Correct Answer
B. SPX
Explanation
SPX is the equivalent to TCP but for the IPX/SPX protocol suite.
SPX = Sequenced Packet Exchange
25.
This protocol is responsible for the logical addressing and routing of messages across the network. It does not ensure the delivery of the packets; that is the responsibility of higher-layer protocols, such as TCP.
This protocol is fully capable of running over either Token Ring or Ethernet networks.
It is a layer 3 protocol.
Correct Answer
C. IP
Explanation
The Internet Protocol (IP) in the TCP/IP protocol suite performs the same routing functions that IPX does for the IPX/SPX protocol suite.
IP = Internet Protocol
26.
This protocol is a transport-layer protocol that is responsible for breaking the data into manageable packets and ensuring that the packets reach their destination. It is considered a connection-oriented protocol, which means that it relies on a session being first established. This is different from a connectionless communication, which just sends the data out and if it reaches the destination, great; if not, no big deal. With connection-oriented protocols, a session is established through introductions. (“Hi, I’m Glen Clarke. Nice to meet you, I am going to send you some data.”) Connection-oriented protocols will monitor that session to ensure that the packets have reached their destination.
Correct Answer
D. TCP
Explanation
TCP = Transmission Control Protocol
27.
This protocol is part of the TCP/IP protocol suite and is the brother of TCP. When you send data on a TCP/IP network and if you need a connection-oriented conversation, you use the TCP protocol. But if you want to have a connectionless conversation you use this protocol. Both TCP and this protocol are layer 4 protocols. IP is used to deliver both types of data, but TCP and this protocol determine whether it is connection oriented or not.
Correct Answer
E. UDP
Explanation
UDP = User Datagram Protocol
28.
This protocol is a protocol for file sharing that enables a user to use network disks as though they were connected to the local machine. It was created by Sun Microsystems for use on Solaris, Sun’s version of UNIX. It is still used frequently in the UNIX and Linux worlds and is available for use with nearly all operating systems. It is a protocol that is used universally by the UNIX community. Vendor and third-party software products enable other operating systems to use it. It has gained acceptance with many companies and can be added to nearly any operating system. In addition to file sharing, it enables you to share printers. It is located in the application layer of the OSI model and is considered a member of the TCP/IP protocol suite. The primary reason to use it is to access resources located on a UNIX server or to share resources with someone working on a UNIX workstation.
Correct Answer
F. NFS
Explanation
NFS = Network File System
29.
These protocols are implemented in redirectors. A redirector is software that intercepts requests, formats them according to the protocol in use, and passes the message to a lower-level protocol for delivery. Redirectors also intercept incoming messages, process the instructions, and pass them to the correct upper-level application for additional processing.
They are used primarily for file and printer sharing in Microsoft and Novell networks, respectively, and are considered application-layer protocols.
Correct Answer
G. SMB and Novell NCP
Explanation
SMB = Microsoft's Server Message Block
NCP = Novell's NetWare Core Protocol

This protocol defines the structure of Internet mail messages. It is a level 7 protocol.
Correct Answer
H. SMTP
Explanation
SMTP = Simple Mail Transport Protocol
31.
This protocol is a standardized method of transferring files between two machines. It is a connection-oriented protocol, which means that the protocol verifies that packets successfully reach their destinations.
This other, closely related protocol has the same purpose and function as the previous, except that it is not a connection-oriented protocol and does not verify that packets reach their destinations. By not verifying that data has been successfully transferred to its destination and therefore requiring less overhead to establish and maintain a connection, it is able to operate faster than the previous protocol. It has no authentication mechanism, whereas the previous protocol can require a username and password.
