Is Your Computer Technician Worth IT? Only If He Passes This Test

To prevent an electrical hazard when repairing a PC, the technician should first disconnect the power before servicing the PC. This is crucial to ensure that there is no electrical current flowing through the components, reducing the risk of electric shock or damage to the equipment. By disconnecting the power, the technician can safely work on the PC without the danger of electrical hazards. Once the power is disconnected, the technician can then proceed with other safety measures such as putting on an ESD strap, placing components on an ESD mat, or placing the PC on a grounded workbench.

An uninterruptible power supply (UPS) is the most suitable solution for preventing file corruption and ensuring a graceful shutdown during extreme weather conditions. A UPS provides battery backup power when the main power source fails, allowing the user to continue working or safely shut down their system. It also protects against power surges and voltage fluctuations, which can cause damage to electronic devices. A surge protector only protects against power surges, while a power strip and power distribution unit do not provide battery backup power.

An uninterruptible power supply (UPS) is the most suitable solution for preventing file corruption and ensuring a graceful shutdown during extreme weather conditions. A UPS provides backup power in case of a power outage, allowing the user to continue working for a certain period of time, typically at least one hour. It also protects against power surges and fluctuations, which can cause damage to electronic devices. A surge protector only protects against power surges, while a power strip and power distribution unit do not provide any backup power.

The correct answer is .bat. A .bat file is a batch file that contains a series of commands that are executed in sequence when the file is run. In this case, the command "net use T:\\server\files" is a command to map a network drive to the letter T, connecting to a server and accessing the files. Therefore, a user would expect to see this command in a .bat file.

The message "No boot device available" will be displayed. This indicates that the computer is unable to find a device from which to boot the operating system. Since the technician has confirmed that the memory, power supply, and monitor are working, and the hard drive is not recognized during the internal diagnostics, it suggests that there may be an issue with the hard drive or its connection to the computer.

Windows 7 would be the best recommendation for this computer because it has lower system requirements compared to the other options. With only 1GB of RAM and 16GB of hard drive space, the computer may struggle to meet the minimum requirements for Windows 8, 8.1, and 10, which typically require more memory and storage space. Windows 7, on the other hand, can run smoothly on this configuration and provide the best performance.

An open license would be the most suitable recommendation in this scenario. An open license allows users to freely use, modify, and distribute the software without any cost. This would fulfill the user's requirement of not wanting to pay for a license while still providing antivirus protection for their home PC.

The most likely cause of the employee being unable to view in-office network folders while working at home is an inactive VPN. A VPN (Virtual Private Network) is a secure connection that allows remote access to the office network. If the VPN is not active or not properly configured, the employee will not be able to connect to the office network and access the network folders.

The network administrator most likely gave the technician a physical network diagram. This document would provide a visual representation of the physical layout of the network, including the switchports that need to be patched in for the upgrade. It would show the connections between devices, such as switches, routers, and servers, and provide information on the physical location of each device. This diagram would be essential for the technician to accurately and efficiently complete the network upgrade.

The technician would most likely set up a Guest account on the kiosk machine. This is because the Guest account is typically used for temporary or limited access, which is suitable for customer interaction in a kiosk. Additionally, the Guest account does not require a password to log in, fulfilling the requirement of automatic login after reboot or power on.

The technician can use Task Manager to resolve the issue. Task Manager allows the technician to view and manage the running processes and applications on the laptop. By closing unnecessary applications and processes, the technician can reduce the CPU utilization and improve the laptop's performance.

Computer technicians require specialized tools for diagnosing and repairing hardware issues. Multimeters measure electrical properties, screwdrivers aid in disassembly, oscilloscopes analyze signals, and soldering irons join components. Telescopes, used for astronomical observation, have no relevance in computer repair.

The technician should use the "grupdate" command-line tool to apply the new policy. This tool is commonly used to update Group Policy settings on a Windows computer. By running the "grupdate" command, the technician can ensure that the new policy denying access to removable hard drives is applied to the network users.

The best method of securing the phone in this scenario would be a fingerprint lock. This is because a fingerprint lock provides a higher level of security compared to other options like passcode, swipe, or PIN locks. Since the phone contains valuable customer PII, a fingerprint lock ensures that only authorized individuals with registered fingerprints can access the data, reducing the risk of unauthorized access or data breaches.

Dumpster diving refers to the act of searching through trash or recycling bins to obtain sensitive or valuable information. In this scenario, the employee reported a suspicious individual looking through the recycle bin, indicating that someone may be attempting to gather information or assets by physically searching through discarded materials. Therefore, the correct answer is dumpster diving.

A 32-bit version of Windows has a memory limit of 4GB. This is because a 32-bit operating system can only address a maximum of 4GB of memory. However, due to system requirements and memory mapping, the actual usable memory may be slightly less than 4GB.

A man-in-the-middle attack is associated with spoofing. In this type of attack, the attacker intercepts communication between two parties and impersonates each party to gain unauthorized access or steal information. The attacker spoofs or impersonates one or both parties involved in the communication, tricking them into believing they are communicating with each other when in fact, the attacker is in control of the communication. This allows the attacker to eavesdrop on the communication, modify the data being transmitted, or even inject malicious code or commands.

SSH (Secure Shell) is the correct answer because it is a secure network protocol that allows remote login and command execution over an encrypted connection. It provides a secure way for the IT firm to access the network switches and routers from a remote location. Telnet, RDP, and VNC are not as secure as SSH and do not provide the same level of encryption and security for remote access.

The technician should ask more open-ended questions to see if the issue can be narrowed down in order to properly identify the issue and save time. This will allow the technician to gather more information about the problem and potentially discover a solution that hasn't been tried yet. By actively engaging with the customer and asking for more details, the technician can work towards resolving the issue more efficiently.

The technician needs to adjust the date and time on the workstation to fix the issue. This is because an invalid certificate error can occur when the date and time on the workstation are not synchronized with the server's date and time. By ensuring that the date and time are correct, the workstation will be able to establish a secure connection with the website using port 443.

Based on the given information, the technician notices missing time slots in the event log, which suggests that there may have been power outages or interruptions. Since the server is experiencing errors and some files are not opening, it is likely that these issues are caused by power fluctuations. Therefore, the technician should replace the battery backup to prevent these issues in the future. The battery backup provides uninterrupted power supply during power outages, ensuring that the server continues to operate smoothly and preventing data loss or corruption.

The technician should restart the network services next. This is because the error message states that Windows Update cannot check for updates because the service is not running, indicating a problem with the network services. Restarting the network services can help resolve the issue and allow the manager to check for updates.

An incompatible partition being marked as active could cause the error "No OS found" after installing a secondary OS. When a computer boots up, it looks for the active partition to load the operating system. If an incompatible partition is marked as active, the computer will not be able to find a compatible operating system to boot from, resulting in the error message.

Time Machine is a built-in utility on Mac that allows users to back up and restore their data. In this scenario, since the operating system became corrupted and files were deleted due to malware, using Time Machine would be the most appropriate choice. Time Machine creates regular backups of the Mac's files, including the operating system, applications, and user data. By accessing the Time Machine backup, the user can restore their system to a previous state and retrieve the data that was previously stored on the Mac.

The technician should use the "Internet Options - Connections" utility to configure the setting. This utility allows the technician to specify the proxy server settings for the Windows workstations.

The user installed additional real-time protection antivirus software, which means there are now two antivirus software programs running simultaneously on the laptop. This can cause conflicts and slow down the performance of the system. To resolve the issue and avoid recurrence, the technician should remove the user-installed antivirus software, leaving only one antivirus software program running on the laptop.

The technician should update the antivirus software, run an antivirus scan, verify the browser settings, and check all email settings. This is the next step to resolve the problem because the symptoms described by the SOHO user suggest a potential malware infection. Updating the antivirus software and running a scan will help detect and remove any malware that might be causing the slow performance and internet connectivity issues. Verifying the browser and email settings will ensure that there are no configuration issues contributing to the problem.

The technician should have covered end-user education as part of the original repair. End-user education involves providing the user with information and guidance on how to prevent future virus infections, how to identify potential threats, and how to safely use the computer to avoid malware. By educating the user, the technician can help them understand the importance of practicing safe browsing habits, regularly updating antivirus software, and avoiding suspicious downloads or email attachments. This knowledge would have helped Joe prevent the recurrence of symptoms and protect his computer from further infections.

SSO, or Single Sign-On, is the security method that allows a user to enter their username and password once, and then gain access to multiple applications without having to re-enter their credentials. This eliminates the need for multiple login prompts, simplifying the user experience and improving efficiency. SSO achieves this by using a centralized authentication system that securely stores and manages user credentials, allowing for seamless authentication across multiple applications.

The reason for Ann's problem is multifactor authentication. Multifactor authentication adds an extra layer of security by requiring users to provide multiple forms of identification, such as a password and a verification code sent to their phone. In this case, when Ann reset her email password, she only changed the password and did not update the authentication method in the third-party email client. Therefore, the client still expects the old authentication method and rejects the new credentials, causing the error message.

Updating the OS of the smartphones should be the first step for the technician because the issue is occurring on two devices with the same model. It is possible that the application requires a newer version of the operating system to function properly. By updating the OS, the technician can ensure that the smartphones have the latest software and any compatibility issues with the application are resolved. Reinstalling the application or rolling back to an earlier version may not solve the problem if it is related to the OS. Clearing the application cache is also unlikely to fix the issue in this case.

Requiring authentication on wake-up ensures that any time the PC is left unattended and goes into sleep mode, users will need to enter a password to access the system again. This helps secure the PC in a public workspace by preventing unauthorized access when the PC is idle. Removing the guest account from the administrators group is good practice but does not directly address network access security. Disabling single sign-on can increase security but may not be necessary if other secure practices are in place. Issuing a default strong password is not a long-term solution since users should change default passwords immediately for better security.

Spear phishing is the correct answer because it involves the use of personalized information to trick individuals into revealing sensitive information or performing certain actions. Unlike regular phishing attacks, which are more generalized and target a large number of people, spear phishing is highly targeted and tailored to specific individuals or organizations. Attackers gather personal information about their targets to make their messages appear more legitimate, increasing the chances of success in obtaining confidential information.

The technician should use the Folder Options utility to edit a protected .dll file. This utility allows the user to customize how folders are displayed and accessed, including showing hidden files and folders. By enabling the option to show hidden files, the technician will be able to locate and edit the protected .dll file that is not visible in the System32 directory.

An unattended installation type requires the use of an answer file to install the OS. This file contains pre-defined responses to the installation prompts, allowing the installation process to proceed without user intervention. This type of installation is often used to deploy the OS on multiple computers simultaneously or to automate the installation process, saving time and effort.

The technician should use the "chkdsk" command to check the integrity of the file system and fix any errors. This can help improve the performance of the PC by resolving any issues with the hard drive. Additionally, the technician should use the "dism" command to repair the Windows image and fix any corruption that may be causing the PC to run slowly. This command can help optimize the system and improve its overall performance.

Designing and developing new software applications is typically the role of a software developer or engineer, not a computer technician. Computer technicians focus on maintaining and repairing existing computer systems and networks. Their tasks include installing and configuring software, troubleshooting hardware and software problems, and replacing faulty components.

The technician should follow the naming convention format of Asset ID, MAC address. This format allows for easy tracking and identification of the client's PCs. The Asset ID provides a unique identifier for each PC, while the MAC address ensures that there are no duplicates. This naming convention format is effective in keeping track of the client's PCs while they are in use.

UPS and server racks are most likely to have a grounding wire attached to them based on the manufacturer's design. This is because UPS (Uninterruptible Power Supply) devices are used to provide backup power to critical equipment, and server racks are used to house servers and other networking equipment. Both of these devices are typically connected to electrical systems and have the potential to generate or attract electrical currents, making it important to have a grounding wire to prevent electrical shocks or damage to the equipment.

The most important step a technician can take to protect against possible infection is to ensure that the server is patched with the latest security updates. Patching the server with the latest security updates helps to address any known vulnerabilities and protect against potential threats and attacks. By keeping the server up to date with the latest patches, the technician can significantly reduce the risk of infection and ensure the server's security.

The best choice for the technician to make in this situation is to ask another technician to take the call. Since the technician is about to go on a break, it would not be appropriate to troubleshoot the issue for the user or input it as a ticket and escalate to Tier 2. Politely asking the user to call back would also not be the best choice as it may lead to frustration for the user. Therefore, assigning the call to another technician ensures that the user's issue is addressed promptly and efficiently.

The technician should first look up the error number associated with the failed update. This will provide more specific information about the cause of the failure and help in troubleshooting the issue. By identifying the error number, the technician can search for solutions or find relevant support articles related to that specific error, which may provide guidance on how to resolve the problem.

Joe can ensure the backups will work if needed by setting up alerts to let administrators know when backups fail. This will allow the IT department to promptly address any issues with the backups and take necessary actions to ensure the data is properly backed up. By being alerted when backups fail, Joe can proactively monitor the backup process and ensure that the data is being successfully backed up on a daily basis.

Joe is unable to access his personal shares on his home media server because a firewall exception must be set. This means that the firewall on Joe's company-issued Windows laptop is blocking the connection to his personal shares. By setting a firewall exception, Joe will allow the necessary network traffic to pass through the firewall and access his personal shares on the home media server.

The contractor should recommend cloud storage as it provides a secure and off-site location for data storage, ensuring that data is not lost even if the hardware is damaged or destroyed. Additionally, the contractor should suggest a hot site, which is a fully equipped and operational backup facility that can be used in the event of a disaster. This will allow the company to quickly resume operations and minimize downtime.

The most likely reasons for the users being unable to access the shares are mapped drives and denied write/delete permissions. Mapped drives could be causing the issue if the data was moved to a different location and the mapped drive is still pointing to the old location. Denied write/delete permissions could be the cause if the users do not have the necessary permissions to access and modify the shares.

The PCs are most likely infected with Zombies and Worms. A Zombie is a type of malware that allows an attacker to remotely control an infected computer. In this case, the PCs are sending out traffic as part of a DDoS attack, indicating that they are being controlled by an external source. A Worm is a self-replicating malware that spreads across a network, infecting other computers. Since multiple internal PCs are involved in the attack, it suggests that a worm has infected these machines and is using them to propagate the attack.

The administrator should put the terminal server into the router's DMZ to increase server security. Placing the server in the DMZ isolates it from the internal network, providing an additional layer of protection against unauthorized access. Additionally, blocking all unused ports on the LAN smart switch helps to prevent any potential vulnerabilities or unauthorized access through those ports, further enhancing server security.

The default login configuration allowed the attack to take place because the attacker was able to gain access to the router using the default username and password. This highlights the importance of changing default login credentials to prevent unauthorized access. Additionally, the WEP configuration also contributed to the attack as it is a weak encryption protocol that can be easily cracked by attackers. Using stronger encryption protocols such as WPA2 should be implemented to enhance network security.
