Look at the list below and decide what is the correct boot sequence.a. POST is runb. NTLDR reads the boot.ini filec. BIOS reads the MBRd. NTLDR loads ntoskrnl.exe and hal.dlle. ntoskrnl.exe starts winlogon.exe
- A.
A, c, e, d, b
- B.
E, c, d, b, a
- C.
A, c, b, d, e
- D.
D, b, e, a, c
Correct Answer
C. A, c, b, d, eExplanation
The correct boot sequence is a, c, b, d, e. First, the POST (Power-On Self Test) is run to check the hardware. Then, the BIOS reads the MBR (Master Boot Record) which contains the boot loader. Next, the boot loader (NTLDR) reads the boot.ini file to determine the operating system to load. After that, NTLDR loads the necessary files ntoskrnl.exe and hal.dll. Finally, ntoskrnl.exe starts winlogon.exe, which initializes the Windows login process.Rate this question:

During the POST process, how many beeps indicates an error with the processor? (Choose 1)
- A.
7 Beeps
- B.
2 Beeps
- C.
5 Beeps
- D.
11 Beeps
- E.
6 Beeps
Correct Answer
C. 5 BeepsExplanation
During the POST process, the system performs a series of tests to check the hardware components. The number of beeps produced by the system speaker indicates the type of error encountered. In this case, 5 beeps indicate an error with the processor. This could be due to a faulty or improperly installed processor, or a problem with the motherboard's connection to the processor.Rate this question:

Which of the following are not TCP/IP attacks? (Choose 2)
- A.
Replay
- B.
SYN Flood
- C.
Worm
- D.
DDoS
- E.
Spam
Correct Answer(s)
C. Worm
E. SpamExplanation
Worm and Spam are not TCP/IP attacks because they do not exploit vulnerabilities in the TCP/IP protocol stack or target specific TCP/IP protocols. Worms are self-replicating malware that spread through networks, while Spam refers to unsolicited bulk emails. On the other hand, Replay, SYN Flood, and DDoS attacks are all TCP/IP attacks. Replay attacks involve the interception and retransmission of network data, SYN Flood attacks exploit the TCP three-way handshake process, and DDoS attacks overwhelm a target system with a flood of traffic.Rate this question:

What benefits does NTFS provide over FAT32? (Choose 2)
- A.
File and folder level permissions
- B.
Limit of 4GB files
- C.
Smaller clusters use more of the available space
- D.
Compatible with Windows 95/98/Me
- E.
Supports 4.17 million files per volume
Correct Answer(s)
A. File and folder level permissions
C. Smaller clusters use more of the available spaceExplanation
NTFS provides file and folder level permissions, which means that users can have different levels of access and control over specific files and folders. This allows for better security and privacy control. Additionally, NTFS uses smaller clusters, which means that it can make more efficient use of the available storage space on a disk compared to FAT32. Smaller clusters reduce wasted space and allow for more efficient storage allocation.Rate this question:

This wireless security protocol was created by Cisco to address weaknesses in WEP & WPA. ____________ is a good choice when using Cisco equipment in a Windows or Linux environment. (1, 2 or 4 words)
Correct Answer(s)
LEAP
Lightweight Extensible Authentication Protocol
EAP-CiscoExplanation
LEAP, also known as Lightweight Extensible Authentication Protocol, is a wireless security protocol created by Cisco to improve upon the weaknesses of WEP and WPA. It is a good choice when using Cisco equipment in both Windows and Linux environments.Rate this question:

Which wireless security protocol is used by devices that employ Wireless Application Protocol? (Choose 1)
- A.
WPA
- B.
WEP 128
- C.
WTLS
- D.
LEAP
- E.
SSID
Correct Answer
C. WTLSExplanation
WTLS (Wireless Transport Layer Security) is the correct answer because it is specifically designed for securing wireless communication in devices that use the Wireless Application Protocol (WAP). WTLS provides encryption, authentication, and integrity protection for data transmitted over wireless networks. It is a lightweight security protocol that is optimized for the constraints of wireless devices, making it suitable for mobile applications. WPA (Wi-Fi Protected Access) and WEP 128 (Wired Equivalent Privacy) are wireless security protocols used in Wi-Fi networks, but they are not specifically associated with WAP. LEAP (Lightweight Extensible Authentication Protocol) and SSID (Service Set Identifier) are not security protocols but rather authentication methods and network identifiers, respectively.Rate this question:

A ________ _______ is a type of TCP/IP attack that randomly opens TCP ports tying up the network resources. (2 words)
Correct Answer
SYN floodExplanation
A SYN flood is a type of TCP/IP attack where the attacker sends a large number of SYN requests to a target server, but does not complete the handshake process. This causes the server to keep waiting for a response, tying up its resources and preventing it from servicing legitimate requests. By opening TCP ports randomly, the attacker can overwhelm the network and disrupt its normal functioning.Rate this question:

What is the 4th step in the Laser printing process? (Choose 1)
- A.
Fusing
- B.
Developing
- C.
Cleaning
- D.
Transferring
- E.
Conditioning
Correct Answer
B. DevelopingExplanation
The 4th step in the Laser printing process is "Developing." Developing involves applying toner to the electrostatically charged drum, which creates the image or text that needs to be printed. The toner is attracted to the charged areas on the drum, forming the desired image. This step is crucial in transferring the image onto the paper during the subsequent steps of the printing process.Rate this question:
