3.
What is the most popular wired network topology?
Correct Answer
B. Star
Explanation
The most popular wired network topology is the star topology. In a star topology, all devices are connected to a central hub or switch, forming a star-like structure. This topology offers several advantages such as easy troubleshooting, scalability, and high reliability. Each device has its own dedicated connection to the central hub, which allows for independent communication and reduces the chances of network failure. Additionally, the star topology allows for easy addition or removal of devices without disrupting the entire network.

D. RJ-45
Explanation
The correct answer is RJ-45. RJ-45 is the registered jack that is commonly used to terminate the standard network patch cable. It has 8 pins and is widely used for Ethernet connections. RJ-99 and RJ-2 are not commonly used registered jacks, while RJ-11 is used for telephone connections.
5.
In a simple home wired network what device would you use to provide more unmanaged/routed Ethernet ports?
Correct Answer
A. Switch
Explanation
A switch is the correct answer because it is a device used to connect multiple devices in a network, allowing them to communicate with each other. It provides more Ethernet ports, which can be used to connect additional devices to the network. Unlike a hub, a switch can intelligently direct network traffic to the appropriate device, improving efficiency and performance. A router, on the other hand, is used to connect multiple networks together and manage the flow of data between them. A KVM (Keyboard, Video, Mouse) is a device used to control multiple computers using a single set of peripherals.

RDP is commonly used for remote administration, technical support, and accessing files and applications on remote computers.
10.
Is a BSOD a hardware or software problem?
Correct Answer
E. Either Is Equally Possible
Explanation
The answer "Either Is Equally Possible" is correct because a BSOD (Blue Screen of Death) can be caused by both hardware and software issues. Hardware problems such as faulty RAM, overheating, or incompatible hardware drivers can trigger a BSOD. Similarly, software issues like incompatible or corrupted software, driver conflicts, or malware can also lead to a BSOD. Therefore, it is not possible to determine whether a BSOD is solely a hardware or software problem without further investigation.
11.
What tool do you use to analyze BSOD crashes?
Correct Answer
B. Windbg
Explanation
Windbg is the correct answer because it is a powerful debugging tool provided by Microsoft that is specifically designed for analyzing Blue Screen of Death (BSOD) crashes. It allows users to examine crash dump files and provides detailed information about the cause of the crash, including the stack trace, memory contents, and register values. Windbg is widely used by developers and system administrators to troubleshoot and diagnose BSOD errors.
12.
In the field of cybersecurity, what does the term "phishing" specifically refer to?
Correct Answer
A. The practice of sending emails that appear to be from reputable sources with the goal of gaining personal information.
Explanation
Phishing is a type of social engineering attack often used to steal user data, including login credentials and credit card numbers. It occurs when an attacker, masquerading as a trusted entity, dupes a victim into opening an email, instant message, or text message. The recipient is then tricked into clicking a malicious link, which can lead to the installation of malware, the freezing of the system as part of a ransomware attack, or the revealing of sensitive information. This method is distinct from other attacks like denial-of-service attacks or vulnerability scanning, making it a unique and common threat in the field of cybersecurity.
13.
What file is a Word 2007 or newer document?
Correct Answer
E. .docx
Explanation
A Word 2007 or newer document is typically saved with the .docx file extension. This file format was introduced in Word 2007 and is used to store documents created in newer versions of Microsoft Word. The .docx format allows for more advanced features and improved compatibility with other software applications. Therefore, the correct answer is .docx.
14.
If you wanted to add a user to a Domain where would you add them?
Correct Answer
C. Active Directory
Explanation
The correct answer is Active Directory because Active Directory is a centralized database that stores and manages information about network resources, including user accounts. It provides a way to organize and manage users, computers, and other network objects within a domain. By adding a user to the Active Directory, they will be granted access to the resources and services available within the domain.
15.
If you can get to a website via direct IP but are unable to via web url what is most likely the problem?
Correct Answer
C. DNS problem
Explanation
If you are able to access a website using its direct IP address but not through its web URL, the most likely problem is a DNS (Domain Name System) issue. DNS is responsible for translating human-readable domain names into IP addresses that computers can understand. If the DNS is not functioning properly, it may not be able to resolve the web URL to the correct IP address, resulting in the inability to access the website through the URL.
16.
What would you use to connect 2 sites to each other so they can access files/printers as if they were in the local building/location?
Correct Answer
A. VPN
Explanation
A VPN, or Virtual Private Network, is used to securely connect two sites together over the internet. It creates a private network connection between the two sites, allowing them to access files and printers as if they were in the same local building or location. This is done by encrypting the data that is transmitted between the two sites, ensuring that it remains secure and private. VPNs are commonly used by businesses to connect remote offices or enable remote workers to access resources on the company's network.
17.
What is SMART?
Correct Answer
B. A hard drive diagnosis built into the drive
Explanation
The correct answer is "A hard drive diagnosis built into the drive." SMART stands for Self-Monitoring, Analysis, and Reporting Technology. It is a system built into hard drives that monitors various attributes of the drive's performance and health. It can detect potential issues or failures before they occur, allowing users to take preventative measures such as backing up data or replacing the drive.
