Question 1

A technician from your IT department needs to understand the difference between EFS and BitLocker. Which of the following statements correctly describe the security features of BitLocker? Choose two.
A)Only administrators can enable or disable BitLocker.
B)User profiles are used to store encryption keys.
C)During the boot process, BitLocker protects system integrity.
D)BitLocker is used when combining the system and boot volumes.

Accepted Answer

Besides the restriction for only administrator-level access, BitLocker scans for unauthorized system changes during the boot process (protecting the system integrity).
Key Takeaway: The NTFS Encrypted File System (EFS) allows any user to encrypt files and doesn't protect system integrity.

Question 2

Of the following options, which are useful in securing servers? Choose all that apply.
A)Configure the firewall.
B)Establish strong password security for BIOS access.
C)Using antivirus software.
D)Using antiphising software.

Accepted Answer

Firewalls, strong passwords, and antivirus protection are essential elements in protecting servers.
Key Takeaway: While there are more procedures to securing servers, these are certainly a part of any security standard to protect servers from internal and external access.

Question 3

The marketing department just installed Windows 7. A manager reports that they are suspicious of a security issue when installing a common and pre-authorized Adobe program. The screens dim, and users are asked if they want to proceed with the install. Is this a security issue?
A)Yes, a virus has been detected.
B)No, power to the screen is diminished during installation of programs.
C)No, the User Account Control operates this way.
D)Yes, the user needs to be logged in as an administrator to install any program.

Accepted Answer

UAC (User Account Control) is a feature that detects changes that typically require administrator permissions. However, the UAC allows users signed in under a general user account the option to install programs using administrator permissions without having to log in as an administrator.
Key Takeaway: UAC was initiated in Windows Vista and carried over to Windows 7. The dimming of the desktop and a security prompt is how the program interacts with users.

Question 4

A remote office needs wireless network security. You advise the local manager to disable the DHCP server on his internal network. Why?
A)This prevents the viewing of the SSID of the network.
B)This prevents the intruder from receiving an IP address.
C)Actually, disabling the DHCP doesn't help improve security.

Accepted Answer

Automatic assignment of an IP address is not available when the DHCP server is disabled.
Key Takeaway: Disabling the DHCP server will improve wireless network security. However, in doing so, you will need to assign an IP address to each computer.

Question 5

David is using a laptop computer with a 1.4 GHz processor. However he notices that the processor is operating at 900 MHz only. Which of the following could be the possible explanation?
A)The processor pins are bent
B)The processor is not seated properly
C)The processor is being throttled
D)The processor is over-clocked

Accepted Answer

If a processor is operating at a speed lower than the one it is designed to operate at, the processor is most likely being throttled. This is done to reduce the dissipated heat and the power consumption in a computer.
Key Takeaway: CPU throttling, also known as dynamic frequency scaling, is a technique that runs the processor at a lower frequency (or, speed) than it is designed to operate. This is primarily done for the following reasons:
1. To reduce heat dissipation in poorly cooled systems.
2. To conserve battery in laptop computers. Operating laptop processors at lower speeds results in less heat generation and reduces cooling costs.

Question 6

Jane is trying to connect a flash drive to her friend's desktop computer. The drive doesn't seem to work in any of the USB ports. However, the drive works on her laptop. Which of the following could be the most likely cause of the issue?
A)The drive works only on laptop computers
B)The processor is faulty
C)The drive is faulty
D)USB is turned off in the desktop BIOS

Accepted Answer

Since the drive is working on the laptop computer, it can be inferred that the flash drive works fine. Most of the time, a good flash drive does not work on a computer because the USB option will be turned OFF in the CMOS setup. Another cause for a flash drive to not work could be faulty USB ports on the desktop computer. Verify the integrity of the ports by connecting good-known USB devices to these ports.
Key Takeaway: The sequence of steps to follow when a USB drive does not work on a USB port is:
1. Try using the drive in any other port. If it works on any one of the slots, that means the other slots are faulty.
2. Try using another good-known drive on these ports.
3. Check if the USB option is turned ON in the CMOS setup.

Question 7

Jonathan has added some more components to his computer and wants to replace the power supply. Which of the following should he check for to replace the power supply effectively? a.

A)a,d
B)a,c
C)a,b
D)b,d

Accepted Answer

Three things you need to check for before you replace the power supply are:
- Type of connectors on the supply
- Number of connectors on the power supply
- Total wattage of the power supply
Key Takeaway: Power supply provides power to all the components on the computer. Before replacing the power supply, check for the type, number of supply connectors, and the wattage to ensure the proper working of the power sub system.

Question 8

David had configured a password to restrict access to the CMOS setup. Which of the following should he do to remove this password and access the CMOS setup?
A)Clear the CMOS by shortening the CMOS jumper
B)Boot to a floppy and fdisk the drive
C)Go into BIOS setup and delete the password
D)Boot down the computer while holding down the <CTRL> key

Accepted Answer

To reset or bypass the CMOS password, clear the CMOS jumper on the motherboard. This clears all the CMOS settings, including the CMOS password.
Key Takeaway: The CMOS password is used to protect any unauthorized changes to the machine's basic configuration. If you forget the password, you will not be able to enter the CMOS setup. To clear this password and enter the setup, do the following:
1. Locate the CMOS jumper on the motherboard.
2. Remove this jumper from its default location.
3. Refer to the manual for the password reset location. Ideally pin #1 and #2 are default, and pin #2 and #3 are used for a password reset.
4. Keep the jumper in the reset location for 20-30 seconds and then place it in the default location.

Question 9

Which of the following determines the drive letter while installing a second hard drive on the computer?
A)Amount of memory
B)Operating system
C)Position on cable
D)Drive manufacturer

Accepted Answer

The position of the drive on the cable determines the letter assigned to the drive.
Key Takeaway: The Windows XP operating system uses the following logic to assign drive letters:
1. Assign the drive letter A to the first floppy disk drive and B to the second floppy disk drive.
2. Assign a drive letter, beginning with C to the first active primary partition recognized on the first physical hard disk.
3. Assign subsequent drive letters to the first primary partition upon each successive physical hard disk drive.
4. Assign subsequent drive letters to every recognized logical partition, beginning with the first hard drive and proceeding through successive physical hard disk drives.
5. Assign subsequent drive letters to any RAM Disk.
6. Assign subsequent drive letters to any additional floppy or optical disc drives.

Question 10

Which of the following is not an attribute of a CMOS battery?
A)CMOS batteries are small and are attached directly to the motherboard
B)CMOS batteries are loosely held to the motherboard by 2-4 clips
C)CMOS batteries produce more waste heat than other forms of logic
D)CMOS batteries are mostly circular in shape (although not always)

Accepted Answer

CMOS devices are designed with two transistors, only one of which is on at any given time. The system draws power only when switching between on and off states, and prodces less waste heat than other devices.
Key Takeaway: CMOS batteries maintain the time, date, hard disk, and other configuration settings in the CMOS memory.

Question 11

Choose the ports that can be used to connect a mouse. (Choose all that apply.)
A)Serial
B)PS/2
C)USB
D)Parallel

Accepted Answer

A mouse can be connected to both PS/2 and USB ports.
Key Takeaway: Always use a PS/2 mouse if the port is available on the motherboard. The USB port can be reserved for other USB devices.

Question 12

Which of the following distinguishes a Firewire port from a USB port? (Choose all that apply.)
A)Firewire ports look just like USB ports except that one of the shorter sides converge
B)Firewire ports are thicker than USB ports
C)Firewire ports are square and USB ports are rectangular
D)There is no visual difference between Firewire ports and USB ports

Accepted Answer

Firewire ports are similar to USB ports, but generally thicker and with the longer sides meeting in a triangular edge at one end.
Key Takeaway: The IEEE 1394 interface is a serial bus interface standard for high-speed communications and isochronous real-time data transfer.

Question 13

John is booting his computer for the first time in 2 weeks. After the CMOS set-up screen, the monitor displays an error message which states "NTLDR is missing". Which of the following options should he use to fix this problem?
A)Boot with a second hard drive.
B)Boot using the Last Known Good Configuration.
C)Perform a system restore.
D)Boot using the Recovery Console.

Accepted Answer

Use the Recovery console to fix the "NTLDR is missing error". You can fix missing or damaged boot files using the Recovery console.
Key Takeaway: The most common causes for a computer to display the error "NTLDR is missing" are:
1. The computer is booting from a non-bootable device.
2. HDD is not set up in the BIOS.
3. Corrupt NTLDR and/or NTDETECT.COM file.
4. Mis-configured boot.ini file.

Question 14

David is switching ON his computer after a month, and an error message displays stating "No operating system found". Which of the following is NOT a possible cause of this issue?
A)A device in SYSTEM.INI cannot be found.
B)No operating system was installed.
C)There are corrupt boot files.
D)The boot sector is corrupt.

Accepted Answer

If a device cannot be found in SYSTEM.INI, it will not lead to the error message "No operating system found." No operating system found, corrupt boot.ini files, or a corrupt boot sector can lead to this error message.
Key Takeaway: Many times you may delete a program or application from your computer, but one of the files is still called by the System.ini, or the Registry. This leads to the error message. To fix this:
1. Open System.ini in Notepad or with Sysedit.
2. Search for the file name and delete the entire line.
3. If it is not found in System.ini, run Regedit, and find the filename.
4. Delete the and close Regedit.

Question 15

You want to install automatic updates on your computer at 3:00 PM every day. Which of the following depicts a path that can be used to configure the automatic installation of updates at the same time each day?
A)Open the Control Panel on the Start menu, go to Automatic Updates, select the Automatic (Recommended) radio button, and specify the time.
B)Open the Control Panel on the Start menu, go to Windows Updates, select the Automatic (Recommended) radio button, and specify the time.
C)Open Automatic Updates in the Administrative Tools menu, select the Automatic (Recommended) radio button, and specify the time.
D)Open Windows Update Scheduler in System Tools, select the Automatic (Recommended) radio button, and specify the time.

Accepted Answer

A standard way of configuring the automatic installation of updates at the same time each day is to open the Control Panel on the Start menu, go to Automatic Updates, select the Automatic (Recommended) radio button, and specify the time. Sometimes Automatic Updates will be displayed directly on the Start menu, but it will always be displayed on the Control Panel.
Key Takeaway: The Automatic Updates tab in the Windows XP lets you configure how you want to handle updating the OS. You can specify that you want to automatically download updates, notify the user when updates are available, or turn off the feature. You can also specify that you want Windows XP to notify you of updates you declined to download at an earlier point in time.

Question 16

Identify the Windows XP command that displays the following output:
A)DEFRAG
B)DXDIAG
C)PING
D)MSCONFIG

Accepted Answer

The output displayed is from the dxdiag command. Dxdiag shows the vital system information like Operating System name, PC model, BIOS version, RAM amount, and DirectX version etc. in the main system tab of its diagnostic tool window.
Key Takeaway: To run dxdiag, you need to type dxdiag in the Run window.

Question 17

What network topology has each node connected to exactly two other nodes, forming a single pathway for the signal to travel on?
A)Star
B)Ring
C)Bus
D)Mesh

Accepted Answer

A ring topology is a network topology or circuit arrangement in which each network device is attached along the same signal path to two other devices, forming a path in the shape of a ring.
Key Takeaway: Identifying a physical ring topology is easy. A ring topology connects to exactly two other nodes, forming a single continuous pathway for signals through each node. Ring topologies are not used these days, due to its apparent disadvantages which include high-impact on network performance if network changes are made and the fact that failure of a single node causes the entire network to fail.

Question 18

Identify the command that displays the following output:
A)Tracert
B)Ping
C)Ipconfig
D)Nslookup

Accepted Answer

The output displayed in the image is from the tracert command. Tracert is a tool that you can use to trace the path that an IP packet takes to its destination from a source. It does this by sending Internet Control Message Protocol (ICMP) Echo Request messages to the destination.
Key Takeaway: To identify the tracert command's output, make sure it has the following columns:
1. Column 1 on the left that increments from 1 to 'n,' where n is the last hop.
2. Columns 2, 3, 4 that denote the time in milliseconds. These effectively denote the time taken by that hop.
3. Column 5 denotes the name or IP address of the router.

Question 19

Which of these tools should be use to enable auditing on a local level?
A)Local Security Settings
B)AD policy
C)Group Policy
D)User Settings

Accepted Answer

At a local level, the security settings should be modified. These include password policy, account lockout policy, audit policy, and user rights management. To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority.
Key Takeaway: It is very crucial to modify these settings to enable a high level of security.

Question 20

Jill is trying to install an antivirus on her computer. In spite of repeated attempts she is not able to install the antivirus software. What could be the most likely problem?
A)It is an old version of the antivirus software.
B)She has just re-installed the operating system.
C)She has Microsoft office running on the computer.
D)She is logged in as a guest.

Accepted Answer

Since she is logged in as a guest, she will not have privileges to install any application on the computer. She would either need to login as an administrator or assign administrator privileges to her account.
Key Takeaway: There are many reasons why an antivirus fails to get installed. They include:
1. Incompatibility with the OS.
2. Another antivirus on the system.
3. User who is trying to install is logged in as a guest.
