Question 1

A new technician has been hired by a company that provides technical services to small businesses.Most businesses want both a wired network and a wireless network.Which of the following wireless security protocols is least secure?
A)WEP
B)WPA
C)WPA2-Personal
D)WPA-Enterprise

Accepted Answer

WEP (Wired Equivalent Privacy) is the least secure wireless security protocol. It uses a weak encryption algorithm, which can be easily cracked by hackers. It is no longer recommended as a security option for wireless networks. WPA (Wi-Fi Protected Access) and WPA2 (Wi-Fi Protected Access II) are more secure options, with WPA2 being the most secure. WPA-Enterprise offers even more security than WPA-Personal, as it provides the ability to authenticate users individually rather than just using a shared password.

Question 2

A tablet mounted in a restaurant for Internet access has multiple web pages open by themselves,and the tablet is running slowly even when playing locally installed games.What should the technician do?
A)Enable a pop-up blocker
B)Restart the tablet
C)Ensure that anti-malware software is installed and up-to-date
D)Change the firewall profile to public

Accepted Answer

The symptoms described suggest that the tablet may be infected with malware. Ensuring that anti-malware software is installed and up-to-date is the best option to address this issue. Enabling a pop-up blocker or changing the firewall profile to public may help prevent further infections but will not remove any malware already present on the device. Restarting the tablet may temporarily alleviate the issue but will not solve the underlying problem.

Question 3

Which security technique would most likely be needed for a nosy admin assistant who happens to wander by when you are logging into your computer?
A)Privacy screen
B)Anti-malware
C)Mantrap
D)Key fob

Accepted Answer

A privacy screen would limit the visibility of the computer screen to only the user in front of it, preventing nosy individuals from seeing the login information. Anti-malware software, mantraps, and key fobs are all security measures that protect against different threats, but would not specifically address the issue of a nosy admin assistant.

Question 4

Which type of network environment would be best for a company that has 30 computers and wants the following capabilities: wired and wireless access,file server,networked printer,centralized authentication to be able to sign on to any computer,shared folders across the network,and a networked scanner?
A)Workgroup
B)HomeGroup
C)Domain
D)VPN

Accepted Answer

A domain environment would be the best choice for a company with 30 computers and the desired capabilities. A domain environment provides centralized authentication, shared folders, and centralized control over network resources such as printers and scanners. Additionally, a file server can be set up to provide file sharing to all computers on the network. While a workgroup could provide some of these capabilities, a domain environment is better suited for a company with multiple users and devices. A VPN is not necessary for this type of network setup.

Question 5

If 50 computers were being upgraded with a new image using Windows Deployment Services,which boot method would a technician use to initiate the deployment?
A)PXE
B)NTFS
C)Optical drive
D)GRUB

Accepted Answer

PXE (Preboot Execution Environment) is the most commonly used method for initiating a network-based deployment. It allows the computers to boot and connect to the network server hosting the deployment image, and begin the installation process without the need for any physical media such as a CD or USB drive.

Question 6

What should a technician do if the Windows installation process shows no storage devices,but the BIOS/UEFI shows a hard drive?
A)Obtain third-party drivers
B)Flash the BIOS/UEFI
C)Start the installation process again
D)Restart the computer and then start the process again

Accepted Answer

If the BIOS/UEFI shows a hard drive but the Windows installation does not, it is likely that the installation does not have the necessary drivers to detect that particular hardware. Obtaining and installing third-party drivers can resolve this issue.

Question 7

What is open source software?
A)Software that is free but that will not fail
B)Software that requires Internet connectivity in order to operate
C)Software that can be used on mobile devices that connect to wireless networks
D)Software that contains the core source code that is modifiable

Accepted Answer

Open source software is software that contains the core source code that can be modified by anyone. It is typically free and offers the ability for users to contribute to the development of the software. A and B are incorrect because open source software can fail and does not necessarily require internet connectivity. C is incorrect because open source software can be used on a variety of devices, including mobile devices, but it is not dependent on wireless networks.

Question 8

Which security tool would help prevent a zero-day attack?
A)Screensaver password
B)Mantrap
C)Biometrics
D)Patch management

Accepted Answer

Patch management involves keeping all software and operating systems up to date with the latest security patches and updates, which can help prevent zero-day attacks. A zero-day attack exploits a previously unknown vulnerability, and by keeping all software systems updated, the vulnerability can be patched before it can be exploited. Screen saver password, mantrap, and biometrics are all security measures, but they would not necessarily prevent a zero-day attack.

Question 9

A technician has been asked to update a salesperson's laptop from Windows 7 Home Premium to Windows 10 Pro.What should the technician do first?
A)Verify that the laptop meets the requirements
B)Back up the data from the hard disk
C)Purchase a license for Windows 10 Pro
D)Defragment the hard drive

Accepted Answer

The technician should first verify that the laptop meets the system requirements for Windows 10 Pro to ensure compatibility and a smooth installation process.

Question 10

A technician is copying files from an NTFS partition to a FAT32 partition.What happens to the permissions assigned to the files?
A)A prompt appears,asking if the technician would like the permissions transferred
B)They are kept without any indication of this
C)They are lost
D)They are imported into the FAT32 permissions

Accepted Answer

FAT32 does not support the same file system permissions as NTFS, so the permissions assigned to the files will be lost during the copying process.

Question 11

A corporate employee notices that all of his social media apps are updating his precise location.What mobile feature should the employee disable to prevent this from happening?
A)Airplane Mode
B)Geotracking
C)Tethering
D)WiFi

Accepted Answer

Geotracking is a feature that allows apps to track the user's precise location, which can be a privacy concern. Disabling this feature will prevent apps from automatically updating the user's location. Airplane mode will disable all communication features, including location services, which may not be desirable in all situations. Tethering and WiFi are not related to location tracking.

Question 12

Which macOS feature allows a technician to view all virtual machines as well as open applications?
A)Mission Control
B)Dock
C)Control Panel
D)Launchpad

Accepted Answer

Mission Control allows a technician to view all virtual machines as well as open applications in a single view. The Dock only shows open applications, the Control Panel is not a macOS feature, and Launchpad shows only installed applications.

Question 13

A company is reviewing its data protection plan.Which of the following should be done on a regular basis in order to prevent data loss if a hard disk fails?
A)Run chkdsk
B)Perform a factory reset
C)Create a backup
D)Restore the system

Accepted Answer

Creating a backup is essential to preventing data loss in the event of a hard disk failure. Regular backups should be made to ensure that the most up-to-date information is saved in case of a system failure. Running chkdsk, performing a factory reset, or restoring the system are all reactive measures that do not necessarily prevent data loss.

Question 14

Which type of partition would a technician deploy on a 4 TB drive?
A)Primary
B)FAT32
C)MBR
D)GPT

Accepted Answer

A 4 TB drive would require a partition table that supports larger drives, such as GPT. MBR is limited to drives with a maximum capacity of 2 TB, so it would not be a suitable choice. Both primary and FAT32 are file system types and do not relate to partition tables, so they are not applicable to this question.

Question 15

Which security measure would be best for a mobile device?
A)Fingerprint lock
B)Facial recognition
C)Privacy filter
D)Numeric passcode lock

Accepted Answer

Fingerprint lock is the most secure option as it is unique to each individual and cannot be easily replicated.

Question 16

Which Linux command is used to search text or a specific file for lines that match a specific text string?
A)search
B)ls
C)apt-get
D)grep

Accepted Answer

The grep command is used to search text or a specific file for lines that match a specific text string. It is a powerful tool that can search recursively through directories, search for multiple patterns at once, and can even be used with regular expressions. The other options (search, ls, apt-get) do not have the same functionality as grep for searching text.

Question 17

What is the best way to prevent unknown devices from connecting to a SOHO wireless router?
A)Disable SSID broadcasting
B)Enable MAC filtering
C)Implement a network domain
D)Toughen the password requirements

Accepted Answer

Enabling MAC filtering allows only specific devices with known MAC addresses to connect to the wireless router, preventing unknown devices from connecting. Disabling SSID broadcasting and implementing a network domain may provide some level of security, but are not as effective in preventing unknown devices from connecting. Toughening the password requirements can improve security, but it does not specifically prevent unknown devices from connecting.

Question 18

After a technician sets up a computer share for an administrative assistant,the next day the assistant calls the technician to report that the share is no longer accessible.What can the technician do so that this doesn't happen every day?
A)Connect the computer to a UPS
B)Train the user in using the Sleep power option
C)Run anti-malware
D)Enable the Reconnect at Logon option

Accepted Answer

Enabling the "Reconnect at Logon" option will ensure that the shared folder remains accessible even after the computer has been restarted or shut down. This option will automatically reconnect the share every time the user logs on, preventing the need for the technician to constantly fix the issue.

Question 19

With which type of network security attack is a man-in-the-middle attack associated?
A)DoS
B)DDoS
C)Smurf
D)Spoofing

Accepted Answer

A man-in-the-middle attack is a type of network attack where an attacker intercepts communication between a client and a server. The attacker then masquerades as the server and relays communication between the client and the actual server, allowing them to intercept sensitive information. This is often accomplished through spoofing, where the attacker pretends to be the server to the client, hence the correct answer is D.

Question 20

An employee who wants to be a technician stands behind a network administrator and watches the administrator type the server password.Later,the employee uses the password to gain access to the server and create a secret administrator account.What specific security threat is this?
A)Social engineering
B)Shoulder surfing
C)Trojan
D)Spear phishing

Accepted Answer

This is an example of shoulder surfing, where someone gains unauthorized access by observing a password or passphrase being typed in. It is not social engineering, which involves manipulating people into divulging confidential information, nor is it a Trojan or spear-phishing attack.
