What does the acronym TCP stand for?

Transport control policy
Technology control protocol
Technical computer processor
Transmission control protocol

Correct Answer

A. Transmission control protocol

Explanation

TCP stands for Transmission Control Protocol. It is a widely used protocol in computer networking that ensures reliable and ordered delivery of data packets over the internet. TCP breaks down large data into smaller packets and reassembles them at the destination. It also includes mechanisms for error detection, flow control, and congestion control to ensure efficient and accurate transmission of data.

Which of following is NOT one of the layers in the Open Systems Interconnection (OSI) model?

Transport
Application
Physical
Security

Correct Answer

A. Security

Explanation

The Open Systems Interconnection (OSI) model consists of seven layers that define the different functions and protocols in a network. These layers are Physical, Data Link, Network, Transport, Session, Presentation, and Application. The layer that is NOT part of the OSI model is Security. While security is an important aspect of network communication, it is not considered as a separate layer in the OSI model. Instead, security is implemented across multiple layers to ensure the confidentiality, integrity, and availability of data.

Which RAID level improves disk performance but doesn't provide any redundancy?

0
1
2
5

Correct Answer

A. 0

Explanation

RAID level 0, also known as striping, improves disk performance by distributing data across multiple disks. However, it does not provide any redundancy or fault tolerance. In RAID 0, if one disk fails, the entire array is at risk of data loss. Therefore, while RAID 0 enhances performance, it is not suitable for applications where data integrity and reliability are crucial.

What does FQDN stand for?

Correct Answer
fully qualified domain name

Explanation
FQDN stands for fully qualified domain name. It is a complete and specific domain name that indicates the exact location of a specific resource on the internet. It includes the host name and the top-level domain, providing a complete address for a specific website or server. The FQDN is necessary for accurate and reliable communication over the internet, as it ensures that requests and data are directed to the correct destination.

UDP is a ____________ protocol

Connetion-oriented
Connectionless
Wireless
Encryption

Correct Answer

A. Connectionless

Explanation

UDP (User Datagram Protocol) is a connectionless protocol. Unlike connection-oriented protocols, such as TCP, UDP does not establish a direct connection between sender and receiver before transmitting data. Instead, it simply sends data packets, called datagrams, without any guarantee of delivery or order. This makes UDP faster and more efficient for certain types of applications, such as streaming media or real-time communication, where a small amount of data loss is acceptable. However, it also means that UDP does not provide error checking or retransmission of lost packets, making it less reliable than connection-oriented protocols.

7.

The physical address of any network device is called the _____________?

IP address
Subnet mask
MAC address
Network IP

Correct Answer

A. MAC address

Explanation

The physical address of a network device is called the MAC address. This address is a unique identifier assigned to each network interface card (NIC) or network adapter. It is used to identify devices within a local network and is essential for the proper functioning of network communication. Unlike IP addresses, MAC addresses are assigned by the manufacturer and cannot be changed.

The IEEE standard for wireless networking is ____________?

802.11
802.3
801.11
802.1

Correct Answer

A. 802.11

Explanation

The correct answer is 802.11. The IEEE standard for wireless networking is 802.11. This standard specifies the protocols and technologies used for wireless local area networks (WLANs). It defines the different variations of Wi-Fi, such as 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac, which provide different speeds and capabilities for wireless communication.

Which of the following is not a benefit of unmanaged switches over hubs?

Eliminate collisions
Allow full deplex connections
Reduce broadcast domains
Improve security

Correct Answer

A. Reduce broadcast domains

Explanation

Unmanaged switches do not have the capability to reduce broadcast domains. A broadcast domain is a network segment in which all devices receive broadcast messages. Switches forward broadcast messages to all connected devices, whereas routers can separate broadcast domains. Therefore, reducing broadcast domains is not a benefit of unmanaged switches over hubs.

What does the acronym SCSI stand for?

Small Computer Systems Interface
Serial Connected Storage Input
System Core Storage Interface
Serial Computer Storage Interface

Correct Answer

A. Small Computer Systems Interface

Explanation

SCSI stands for Small Computer Systems Interface. It is a set of standards for physically connecting and transferring data between computers and peripheral devices. SCSI allows multiple devices, such as hard drives, tape drives, and scanners, to be connected to a computer simultaneously, providing a high-speed and reliable data transfer interface.
