During the boot process, the registry loads into what type of memory?
- A.
ROM
- B.
EEPROM
- C.
RAM
- D.
FLASH
Correct Answer
C. RAMExplanation
During the boot process, the registry loads into RAM. RAM (Random Access Memory) is a type of computer memory that is volatile, meaning its contents are lost when the power is turned off.

Which file system offers the most security?
- A.
NTFS
- B.
FAT16
- C.
FAT32
- D.
OSPF
Correct Answer
A. NTFSExplanation
NTFS (New Technology File System) offers the most security compared to the other file systems listed. NTFS provides features such as file and folder permissions, encryption, auditing, and access control lists (ACLs), which enhance security and protect data from unauthorized access or modifications. It also supports advanced security mechanisms like file system journaling and disk quotas. In contrast, FAT16 and FAT32 lack these advanced security features, making them less secure options. OSPF (Open Shortest Path First) is a routing protocol and not a file system, so it is not relevant to the question.Rate this question:

What tool is used to analyze a hard drive and consolidate files and folders improving drive efficiency?
- A.
System Configuration
- B.
Disk defragmenter
- C.
Task Manager
- D.
Dr. Watson
Correct Answer
B. Disk defragmenterExplanation
Disk defragmenter is a tool used to analyze a hard drive and consolidate files and folders, improving drive efficiency. When files are saved or deleted on a hard drive, they can become fragmented, meaning that parts of a file are scattered across different locations on the drive. This can slow down the computer's performance. Disk defragmenter rearranges the fragmented files, placing them closer together and in a more organized manner, which allows for faster access and improved efficiency when accessing files on the hard drive.Rate this question:

The protocol suite used for Internet connectivity is:
- A.
TCP/IP
- B.
NetBEUI
- C.
IPX/SPX
- D.
All of the above
Correct Answer
A. TCP/IPExplanation
The correct answer is TCP/IP because it is the most widely used protocol suite for Internet connectivity. TCP/IP stands for Transmission Control Protocol/Internet Protocol and it is a set of protocols that allows computers to communicate with each other over the Internet. TCP/IP provides reliable and efficient data transmission, addressing, and routing capabilities, making it the foundation for Internet communication. NetBEUI and IPX/SPX were also used in the past for local area networks, but they are not commonly used for Internet connectivity. Therefore, the correct answer is TCP/IP.Rate this question:

Each network interface card has a unique 48 bit number burned into ROM called (an):
- A.
Token
- B.
MAC address
- C.
IP address
- D.
Host address
Correct Answer
B. MAC addressExplanation
A MAC address, or Media Access Control address, is a unique identifier assigned to each network interface card. It is a 48-bit number burned into ROM, which distinguishes one device from another on a network. The MAC address is used at the data link layer of the OSI model to ensure that data packets are correctly delivered to the intended recipient. Unlike IP addresses, which can change and are assigned by a network administrator, MAC addresses are permanent and cannot be modified or reassigned.Rate this question:

OSI is an acronym for:
- A.
Open System Interconnect
- B.
Operating System Interface
- C.
Ongoing Standard Integrity
- D.
Output System Input
Correct Answer
A. Open System InterconnectExplanation
The correct answer is Open System Interconnect. OSI is a reference model that defines how different software and hardware components in a network should communicate with each other. It consists of seven layers, each responsible for specific tasks in the network communication process. The term "Open System" refers to the ability of the model to work with different types of systems and technologies, while "Interconnect" emphasizes the model's focus on enabling seamless communication between these systems.Rate this question:

In an Ethernet network, a ___________ connection is one that can transmit data in both directions, but not at the same time.
- A.
Full duplex
- B.
Simplex
- C.
Parallel
- D.
Half-duplex
Correct Answer
D. Half-duplexExplanation
In an Ethernet network, a half-duplex connection allows for data transmission in both directions, but not simultaneously. This means that data can be sent or received, but not both at the same time. In contrast, a full-duplex connection allows for simultaneous two-way communication, while simplex allows for one-way communication only. Parallel does not describe the type of connection in terms of simultaneous data transmission.Rate this question:

What encryption method used with wireless networks?
- A.
Shared
- B.
WEP
- C.
VPN
- D.
SSID
Correct Answer
B. WEPExplanation
WEP (Wired Equivalent Privacy) is an encryption method used with wireless networks. It was one of the earliest methods used to secure wireless networks, but it is now considered to be weak and easily compromised. WEP uses a shared key authentication and encryption system, where all devices on the network use the same key to encrypt and decrypt data. However, WEP has several vulnerabilities that make it susceptible to attacks, such as the ability to crack the encryption key through packet sniffing. Therefore, it is no longer recommended to use WEP for securing wireless networks.Rate this question:

Which of the following is NOT and example of a network topology?
- A.
Star
- B.
Ring
- C.
Bus
- D.
Peer
Correct Answer
D. PeerExplanation
The term "peer" does not refer to a network topology, but rather to a type of network connection or relationship. In a peer-to-peer network, devices are connected directly to each other without a central server. Network topologies, on the other hand, refer to the physical or logical layout of devices and connections in a network, such as star, ring, or bus. Therefore, "peer" is not an example of a network topology.Rate this question:

One of the oldest network topologies is the:
- A.
Bus
- B.
Mesh
- C.
Ring
- D.
Star
Correct Answer
A. BusExplanation
The correct answer is Bus. A bus network topology is one of the oldest and simplest forms of network architecture. In this topology, all devices are connected to a single cable called the bus. Each device on the network can transmit data onto the bus, and all other devices receive that data. This makes it easy to add or remove devices from the network. However, if the bus cable fails, the entire network can go down.Rate this question:

The two major classifications of fiber optic cable are:
- A.
Single and multi-mode
- B.
Plastic and glass
- C.
Flexible and inflexible
- D.
Colored and monochrome
Correct Answer
A. Single and multi-modeExplanation
The correct answer is single and multi-mode. Fiber optic cables are classified based on the way they transmit light signals. Single-mode cables have a smaller core and allow only one mode of light to propagate, resulting in longer transmission distances. Multi-mode cables have a larger core and support multiple modes of light, making them suitable for shorter distances. Plastic and glass, flexible and inflexible, and colored and monochrome are not the classifications used for fiber optic cables.Rate this question:

The access method used by wireless networks is ______.
- A.
Token passing
- B.
CSMA/CA
- C.
CSMA/CD
- D.
Mesh
Correct Answer
B. CSMA/CAExplanation
CSMA/CA stands for Carrier Sense Multiple Access with Collision Avoidance. It is the access method used by wireless networks to ensure that multiple devices can access the network without causing collisions. In CSMA/CA, devices listen to the network before transmitting to check if it is busy. If the network is busy, they wait for a random amount of time before attempting to transmit again. This helps to avoid collisions and ensures efficient utilization of the wireless network.Rate this question:
