VBScript uses a file extension of .vbs.

48. Match the file system term used in Linux to the function.

The certification objectives list the words “swap file system” as a term to be defined as it relates to the Linux file system. Swap space, swap file, or swap partition are other words for describing hard drive space that is used when the system needs more memory than there is RAM.

49. Which two data storage locations contain persistent data that can be used by computer forensics specialists? (Choose two.)

  • cache
  • RAM
  • CPU registers
  • hard disk drives
  • solid state drives

Explanation: Persistent data is data stored on an internal or external hard drive, or an optical drive. Data is preserved when the computer is turned off.

50. On which two occasions is it most likely that a technician will have to perform a clean operating system installation if a backup has not been performed? (Choose two.)

  • The existing operating system is corrupted.
  • The computer is being moved to a different network.
  • A user requires access to a new printer.
  • The existing security software requires upgrading.
  • A new replacement hard drive is installed in a computer.

51. Which three items are biometric security devices? (Choose three.)

  • smart card
  • fingerprint reader
  • password
  • key fob
  • voice recognition
  • retina scanner

Explanation: Fingerprint readers, retina scanners, and voice recognition are all biometric devices, comparing physical characteristics of the user to stored data to authenticate the user. Smart cards, key fobs, and passwords are all security measures, but do not rely on biometrics.

52. Which two guidelines are appropriate for creating strong passwords? (Choose two.)

  • Include letters, numbers, and symbols.
  • Passwords should contain symbols only.
  • Change the password once each year.
  • Use at least eight characters.
  • Use only upper case and numeric values in passwords.

Explanation: Strong passwords should be at least eight characters, and should include upper and lower case letters, numbers, and symbols. Although passwords should be changed regularly as specified in the local security policy, the amount of time between changes has no effect on the creation of strong passwords. Limiting a password to only symbols, or to only numbers and upper case letters, does not provide the strongest password possible.

53. A support desk technician is dealing with an angry customer. Which two approaches should the technician take in dealing with the customer? (Choose two.)

  • Ask socially related questions to direct the customer away from the problem.
  • Let the customer explain the problem without interrupting.
  • Immediately transfer the customer to a higher level technician.
  • Work to redirect the conversation to solving the problem.
  • Reply to the customer with the same level of anger.

Explanation: Angry customers should be allowed to explain the problem, then be redirected to discussing how the problem can be solved. Transferring the customer, replying in a rude tone, and asking unrelated questions will usually increase, not ease, the anger being expressed by the customer.

54. A technician working on a computer discovers what is suspected to be illegal activity. Which three pieces of information should be immediately documented? (Choose three.)

  • evidence of the suspected illegal activity
  • technical specifications of the computer
  • why the computer was accessed by the technician
  • location of the computer
  • details of all past users of the computer
  • duration of the suspected illegal activity

Explanation: The initial reason for accessing the computer, the suspected illegal matter or operations, and the location of the computer are immediately apparent to the technician and should be among the first details documented. Details of past computer users and the duration of the illegal activity are matters that the appropriate investigators will determine. The technical specifications of the computer may have little relevance to its illegal use.

55. What two roles or tasks are associated with level two technicians? (Choose two.)

  • prioritizing incoming calls according to their severity
  • remotely updating drivers and software on customer computers
  • escalating a trouble ticket to a higher level technician

  • gathering customer information to initiate a work order

Explanation: Level two technicians are primarily tasked with receiving and working on escalated work orders. Their tasks involve using remote access software to connect to the computer of a customer to perform maintenance and fixes.

56. A store in a shopping center uses a wireless network to provide internet access for three tablet computers. The authentication to the wireless router has been configured as 128-bit WEP. Recently the store employees notice that the internet connection is getting slower. The network administrator of the shopping center reviews the logs of the wireless router and notices many non-store devices are associated with the router. Which two actions can the network administrator do to improve the security of the wireless network access? (Choose two.)

  • Use the MAC address filtering feature.
  • Change WEP to WPA2 protocol.
  • Ensure that the shared key is randomly generated.
  • Use a 32-character long SSID.
  • Change to the 152-bit WEP protocol.

Explanation: The SSID is used to identify the wireless LAN and should not be considered a method for securing the WLAN. WEP encryption is weak and prone to attacks with wireless hacking tools. WEP should not be used and has been replaced by the much more secure WPA2 protocol. MAC address filtering can ensure that only authorized devices can be associated with the wireless router.

57. A user is hiking in a city park. The user wants to make a call home but cannot get a reliable cellular signal. What are two possible causes for the bad cellular coverage? (Choose two.)

  • The distance to the nearest Wi-Fi access point is too far.
  • The user is located between coverage areas of the carrier.
  • The location service is turned off.
  • The Bluetooth headset is unpaired.
  • There are not enough cell towers in the area.

Explanation: A mobile user may experience weak or dropped signal issues if there are not enough cell towers surrounding the area or the location is not covered well by the carrier.

58. A user purchases a new smartphone and is trying to use a high quality Bluetooth headset on the new device. However, the headset is not connected to the smartphone. What are three settings that the user needs to check to troubleshoot the problem? (Choose three.)

  • The battery capacity on the smartphone is above 50%.
  • The USB port on the headset is working.
  • The authentication service is turned on.
  • The Bluetooth connection is enabled on the smartphone.
  • The headset is turned on.
  • The pin code is entered correctly.

Explanation: Three factors contribute to a successful pairing between a Bluetooth capable host (the smartphone in this case) and a Bluetooth device (the headset):

  • The Bluetooth device is turned on.
  • The pin code is entered correctly.
  • The Bluetooth connection is enabled on the mobile device.

59. A third-party security firm is performing a security audit of a company and recommends the company utilize the Remote Desktop Protocol. What are two characteristics of the Microsoft Remote Desktop Protocol (RDP)? (Choose two.)

  • RDP uses an encrypted session.
  • RDP connects on TCP port 3389.
  • RDP requires a Windows client.
  • RDP is a command-line network virtual terminal protocol.
  • RDP connects on TCP port 22.

Explanation: The Remote Desktop protocol (RDP) is used to remotely access a Windows OS. It is a client/server protocol.The port number for RDP is TCP port 3389 and it uses encryption.

60. A computer can successfully ping outside the local network, but cannot access any World Wide Web services. What is the most probable cause of this problem?

  • Windows Firewall blocks port 23 by default.
  • The computer network interface card is faulty.
  • The BIOS or CMOS settings are blocking web access.
  • Windows Firewall is blocking port 80.

Explanation: The World Wide Web (HTTP) protocol uses port 80; port 23 is used by Telnet. Successful pings to other devices indicate that the network interface card is working correctly. BIOS and CMOS settings control system hardware functions, not network applications such as the World Wide Web.

61. Which question would be an example of an open-ended question that a technician might ask when troubleshooting a security issue?

  • Have you scanned your computer recently for viruses?
  • Is your security software up to date?
  • Did you open any attachments from a suspicious email message?
  • What symptoms are you experiencing?

Explanation: Close-ended questions generally have a fixed or limited set of possible responses, such as “yes” or “no”. Open-ended questions imply no limited or fixed set of replies but rather generally prompt the responder to provide more meaningful feedback.

62. A technician is troubleshooting a computer security issue. The computer was compromised by an attacker as a result of the user having a weak password. Which action should the technician take as a preventive measure against this type of attack happening in the future?

  • Ensure the security policy is being enforced.
  • Verify the physical security of all offices.
  • Scan the computer with protection software.
  • Check the computer for the latest OS patches and updates.

Explanation: As part of the fifth step of the troubleshooting process, technicians should apply preventive measures whenever possible. Most company security policies include a section on password complexity and length requirements. Ensuring that this policy is being enforced can help prevent attackers from being able to compromise systems through password cracking.

63. A user notices that some of the programs that are installed before upgrading to Windows 7 no longer function properly. What can the user do to fix this problem?

  • Lower the UAC setting in the Change User Account Control settings dialog box of the User Accounts control.
  • Reinstall the programs in Compatibility Mode.
  • Update the driver for the graphics card.
  • Change the file system to FAT16.

Explanation: UAC is used to change user account settings while converting the file system to FAT16 and updating the driver for the graphics card will not resolve the issue. Compatibility mode in Windows 7 allows for the running of a program created for previous versions of the Windows environment.

64. In which folder are application files for 32-bit programs typically located on a computer that is running a 64-bit edition of Windows 7?

  • C:\Users
  • C:\Program Files (x86)
  • C:\Application Data
  • C:\Program Files

Explanation: The C:\users folder contains all the user profiles. The C:\Application Data folder contains application data related to all users. The 32 bit program files are located in the C:\Program Files(x86) folder while 64 bit program files are located in the C:\Program Files folder.

65. What is required in order to connect a Wi-Fi enabled laptop to a WPA secured wireless network?

  • a security encryption key
  • a MAC address
  • a username and password
  • an updated wireless driver

Explanation: Regardless of the levels of security configured on a WLAN, a WPA secured WLAN always requires the use of an encryption key. Without the proper key, a device cannot connect to the network.

66. What is a feature that can be used by an administrator to prevent unauthorized users from connecting to a wireless access point?

  • MAC filtering
  • WPA encryption
  • software firewall
  • proxy server

Explanation: Limiting a certain set of MAC addresses to connect to an access point is a way to ensure that only those devices are allowed to use the wireless network. A software firewall is used to prevent other users from gaining access to the protected computer. Configuring WPA encryption does not guarantee that the unauthorized user will not find the way to connect to the network. A proxy server is mostly used to filter traffic based on content.

67. A user is configuring a wireless access point and wants to prevent any neighbors from discovering the network. What action does the user need to take?

  • Configure a DNS server.
  • Disable SSID broadcast.
  • Enable WPA encryption.
  • Configure DMZ settings.

Explanation: Disabling SSID broadcast prevents the access point from announcing the name of the network. Enabling WPA encryption, configuring DMZ settings, and configuring a DNS server will accomplish different tasks, but the name of the network will still be announced.

68. Which setting must be turned on in order to share a printer in Windows 7?

  • Sharing
  • Share this Printer
  • Windows Firewall
  • File and Printer Sharing

Explanation: File and Printer Sharing must be turned on in order to share a printer in Windows 7. Share this Printer is a setting in Windows XP. Sharing is a setting in Windows Vista. Windows Firewall is not required to be turned on in order to share a printer.

69. A user is able to only access files required to perform a specific task. What type of security practice is being applied?

  • principle of least privilege
  • principle of most privilege
  • principle of privileges
  • principle of necessary privilege

Explanation: Limiting access to files or folders that are needed to perform a specific job is known as the principle of least privilege. The other options do not exist.

70. A technician is troubleshooting a workstation in a domain that has been infected with a virus. What is the first step the technician should take to clean the infected workstation?

  • Run the antivirus software.
  • Turn off system restore.
  • Disconnect the workstation from the network.
  • Update the antivirus software.

Explanation: The first step is to disconnect the infected workstation from the network. This will quarantine the infected workstation and prevent the virus from spreading throughout the network.

71. A technician is about to install and configure a wireless network at a small branch office. What is the first security measure the technician should apply immediately upon powering up the wireless router?

  • Disable the wireless network SSID broadcast.
  • Configure encryption on the wireless router and the connected wireless devices.
  • Change the default user-name and password of the wireless router.
  • Enable MAC address filtering on the wireless router.

Explanation: The first action a technician should do to secure a new wireless network is to change the default user-name and password of the wireless router. The next action would usually be to configure encryption. Then once the initial group of wireless hosts have connected to the network, MAC address filtering would be enabled and SSID broadcast disabled. This will prevent new unauthorized hosts from finding and connecting to the wireless network.

72. A company has a preventive maintenance policy that requires every computer have a new restore point created every six months. For computers using the Windows 7 operating system, how can a technician create the restore point?

  • From the CLI enter the command restore /cn.
  • Choose Start > Control Panel > Accessories > System Tools > System Restore > Create a restore point.
  • Choose Start > All Programs > Accessories > System Tools > System Restore > Next.
  • Right-click My Computer and then choose Properties > Restore > Create Restore Point.

73. What does virtual memory provide to an operating system?

  • the creation of virtual partitions on the hard drive
  • an increase in data storage
  • an increase in the speed of accessing RAM
  • a temporary storage of data until enough RAM is available to process it

Explanation: The OS uses virtual memory when a computer does not have enough RAM available to run a program. Virtual memory moves data from RAM and places it in a paging file on the hard drive. A paging file is a place where data is stored until enough RAM is available to process the data. This process is much slower than accessing the RAM directly.

74. Why would an administrator use Windows Remote Desktop and Windows Remote Assistant?

  • to provide secure remote access to resources on another network
  • to connect to a remote computer over the network to control its applications and data
  • to connect to an enterprise network across an unsecured connection and act as a local client of that network
  • to enable sharing of files and presentations with a group of users over the Internet

Explanation: Windows Remote Desktop and Remote Assistant allow an administrator to connect a local computer with a remote computer across the network and to interact with it as though it were the local computer. The administrator sees and can interact with the desktop of the remote computer. With Remote Desktop, the administrator logs onto the remote computer using an existing user account and starts a new user session. No user is required at the remoter computer to allow this access. With Remote Assistant, the purpose is for a technician to interact with a remote computer with the assistance of a remote user. The remote user must allow the remote access to the current user session and is able to observe what the technician is doing.

75. A technician needs to check the system settings on a remote computer to make sure it will be compatible with a new software update that will be sent out. The technician will use an administrator account to log in and start a user session on the remote PC. Which Windows tool will the technician use to accomplish this?

  • Windows file sharing services
  • Windows VPN remote access client
  • Windows Remote Desktop
  • Windows Update Assistant

Explanation: Windows Remote Desktop allows a technician to log in to a remote computer through an existing user account. The technician can run programs and view and manipulate files within the system of the remote computer.

76. A business traveler connects to a wireless network with open authentication. What should the traveler do to secure confidential data when connecting to the business services?

  • Connect with a VPN.
  • Change the network location profile to public.
  • Change the Windows firewall settings.
  • Manually configure an IP address, subnet mask, and default gateway.

Explanation: A VPN is used to form a secure tunnel across a public network. This technology allows users to communicate over an insecure network and yet keep data confidential. Changing the network location profile will modify firewall settings on a computer but not increase the confidentiality of data crossing a network. Modifying the IP address, subnet mask, and default gateway will not change the confidentiality of data transmitting on a network.

77. What determines the level of support that a call center technician will provide to an individual customer?

  • A level one technician will provide a higher level of support than a level two technician.
  • Support is based on the SLA for that customer.

The first step to remediating an infected computer is to remove the computer from the network to prevent other computers from becoming infected. The next step is to follow any incident response policies that are in place. The log files should be saved to a removable media for further analysis. Restarting an infected PC may destroy the evidence of infection.

97. All Windows 10 computers in a small advertising company are configured with the System Restore service. One of the PCs was infected by malware when an employee was doing research on the internet. The IT administrator scans the system and deletes the malware from the Quarantined Items folder. What should the administrator do next to complete the remediation process?

  • Delete all restore points.
  • Disable the System Restore service.
  • Create a restore point.
  • Restore the system from a backup.

Explanation: Once the System Restore service is turned on, a PC will create regular restore points. When the PC is infected with malware, the system restore points may contain infected files. Deleting all system restore points after the system has been remediated, prevents bringing infected files into the system when the System Restore service is needed.

98. A mobile user downloads and installs an app. Once the app is installed, the Android mobile device is frozen. What is a cause for the issue?
