CompTIA A+ 220-1002 - Prep Quiz

A UPS (Uninterruptible Power Supply) is the correct recommendation in this scenario. A UPS provides battery backup power to devices in the event of a power outage or fluctuation. This will prevent file corruption by allowing the devices to shut down properly without losing any data. Additionally, a UPS can provide at least one hour of uptime during extreme weather conditions, ensuring that critical operations can continue even if the power supply is disrupted. Surge protectors, power strips, and power distribution units do not provide the same level of protection and backup power as a UPS.

An Inactive VPN is the MOST likely item to inhibit a remote worker.

Ann is experiencing unauthenticated wireless connectivity. The presence of a "?" in the radio icon suggests that the phone is connected to the public hotspot, but it is not able to authenticate and establish a proper connection. This is why she is unable to access the internet and sees the "page cannot be displayed" message.

*##*SSO (Single-Sign On) is the only option that allows an end-user to enter the same username and password once to use for multiple applications.*##*Permission propagation, Inheritance, and MFA (Multi-Factor Authentication) do not offer this option.

The Administrator and Power User privilege are too much for these users and Remote Desktop User doesn't apply here. Guest is the most likely option.

While none of these options are bad, you should not work in a PC still receiving power. That's the absolute first thing to do!

After restarting the computer and finding that the OS still does not load, the technician should attempt to reboot into safe mode and roll back the updates. This is because the black screen issue could be caused by a recent patch or update that is incompatible with the system. By booting into safe mode, the technician can access the system with minimal drivers and services, allowing them to uninstall or roll back the problematic update. This can potentially resolve the issue and allow the OS to load properly. Repairing the Windows Registry, disabling Windows services and applications, or configuring boot options in the BIOS may not directly address the issue of the OS not loading after a recent update.

An in-place upgrade is the appropriate method for the technician to use in this scenario. This method allows the technician to install the latest OS without affecting the user's settings and files. It essentially upgrades the existing OS to the latest version while preserving all the user's data and configurations. This ensures a seamless transition for the user without the need to reconfigure settings or restore files from a backup.

Making sure the date and time are correct is how the computer knows if a certificate is expired or not. None of these options would interfere in this process as much as an un-adjusted date and time.

All 32-bit systems have a maximum RAM of 4GBs, often less.

If you're a massive nerd saying " well you can use a PAE (Physical Adddress Extension to access up to 64GBs), that's cool and all but unless you're running Windows Server then any other copy of Windows won't support PAE.

Dumpster diving is exactly how it sounds. The individual looks in your waste to find material.

This is a question meant to trick you into thinking it's a specifications issue. Technically, the user's Windows XP machine meets the minimum 32bit requirements for all 4 versions of Windows. However, it says "upgrade" not Clean Install.

 

There is not a direct option to upgrade to Windows 8+. But there is an option to upgrade to Windows 7. The difference between upgrading and a clean install would be the loss of files and settings. 





 

An Open License is the only license that is free.

The technician should use the "Folder Options" utility in the Control Panel. This utility allows the user to customize various settings related to folders and files, including the ability to view and modify protected system files. By enabling the option to show hidden files and folders, the technician will be able to locate and edit the protected .dll file that they need.

If the battery backup went down during an outage, then that would directly explain the missing time and seemingly the corrupted files/backups.

The question is which CMD tool allows a technician to apply a new policy. The only option here that can do that is gpupdate which stands for for group policy update.

Disabling the user accounts would be the best way to enforce the company's security policy. By disabling the user accounts, the contractors will not be able to log in to the laptops after the inventory is completed, ensuring that they cannot access the laptops until the next inventory. Deleting the user accounts would permanently remove them, which may not be necessary if the contractors will be returning for future inventories. Restricting the user accounts may still allow contractors to log in but with limited access, which does not align with the policy. Resetting the user accounts would only reset the passwords, but the contractors would still be able to log in.

During construction, there is likely to be a lot of dust and debris in the air, which can be harmful to the sensitive equipment in a server room. Using air filters at the site will help to remove these particles from the air, ensuring a clean and safe environment for the servers. This will help to prevent any damage or malfunctions that could be caused by the dust and debris. Therefore, air filters are necessary while setting up the temporary server room during construction.

The technician should ask more open-ended questions to try and narrow down the issue. By asking specific questions, the technician can gather more information and potentially identify the problem more efficiently. This approach can help save time by avoiding unnecessary troubleshooting steps that have already been tried by the customer. It also shows the technician's commitment to resolving the issue and addressing the customer's concerns.

The correct answer is PXE. PXE stands for Preboot Execution Environment, which is a boot method that allows computers to boot from a network instead of a local storage device like an SSD, optical drive, or flash drive. In this scenario, since the technician only has one disc for the installation, they choose to upgrade over the network using PXE to initiate the upgrade process on multiple machines.

Any other option besides Single-factor means there is another point asking the end user for authentication or authorization. But since there isn't, then single-factor is the only option.

Installing multiple real-time protection antivirus software programs can cause conflicts and slow down the performance of the laptop. Removing the user-installed antivirus software will eliminate any conflicts and improve the performance of the laptop.

Compared to the other options, a Badge Reader and Biometric lock would be the most secure. both would identify the specific user and combined, they would make it even harder to gain access.

*##*Fingerprint Locking is the most secure of these 4 options. Biometric security makes it harder while the other options can be brute forced or provide no security.*##*Swipe lock doesn't provide any security.

A PIN can be brute forced easily

A passcode is secure to a point, but it's not as secure as a biometric lock.

SSH (Secure Shell) is the correct answer because it provides a secure and encrypted method for accessing network devices such as switches and routers. Unlike Telnet, which sends data in clear text, SSH encrypts the data, making it more secure against unauthorized access or eavesdropping. RDP (Remote Desktop Protocol) and VNC (Virtual Network Computing) are used for remote desktop access and control, but they are not typically used for managing network devices. Therefore, SSH is the most appropriate choice for securely accessing the devices in this scenario.

The correct answer is "sudo". The sudo command in Linux allows a user to run programs with the security privileges of another user, typically the superuser or root. By using sudo, the junior Linux system administrator can gain the necessary permissions to update the system software.

PII, or Personally Identifiable Information, is considered government-regulated data because it refers to any information that can be used to identify an individual, such as their name, social security number, or address. Governments often have regulations in place to protect the privacy and security of PII, as its misuse can lead to identity theft or other forms of harm. Therefore, PII is subject to government regulations and organizations handling such data are required to comply with specific security and privacy standards.

You want to perform to the best of your ability while meeting the obligations of your workplace. The best option is to have another technician that is available.

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 or resource-intensive applications, the technician can reduce the CPU utilization and improve the laptop's performance. However, since the issue persists the next day, there may be underlying factors causing the high CPU utilization that need to be further investigated.

UPS (Uninterruptible Power Supply) and server racks are both devices that are commonly used in data centers or server rooms where the grounding of electrical equipment is crucial for safety and proper functioning. UPS devices often have grounding wires to ensure that any electrical faults are safely directed to the ground. Server racks also typically have grounding wires to prevent static electricity buildup and to protect sensitive equipment from electrical surges. On the other hand, desktop printers, patch panels, and modems are not typically designed with grounding wires as they are not as sensitive to electrical issues as UPS and server racks.

To increase the security of the wireless network in a crowded building, the installation technician should perform two actions. Firstly, reducing the transmit power will limit the range of the wireless signal, making it harder for unauthorized users outside the office to connect to the network. Secondly, disabling the SSID broadcast will prevent the wireless network from being easily detected by potential attackers, as the network name will not be visible in the list of available networks. These two measures together help to minimize the chances of unauthorized access and enhance the overall security of the wireless network.

Shoulder surfing is a technique used by malicious employees to obtain user passwords. It involves the act of looking over someone's shoulder while they are entering their password, in order to gain unauthorized access to their accounts. This method allows the malicious employee to easily observe and memorize the password without the victim's knowledge. It is a form of social engineering attack that exploits human vulnerabilities and lack of awareness about the surroundings.

*##*Updating the antivirus software, running a scan, verifying the browser settings are correct along with the hosts file and checking all email settings will provide a better resolution to the problem than changing more settings.*##*What's being described here is a connection issue. Modifying the BIOS and changing the OS is a leap but also not relevant to the immediate issue of the internet. The technician found nothing wrong with the CPU, only slow loading pages and periodic connections dropped.

Sending a test email, running a file system check, and emptying the browser cache isn't necessarily wrong but doesn't seem like something that will resolve the problem.

An incompatible partition being marked as active is the most likely cause of the error "No OS found" after installing a secondary OS. When a partition is marked as active, the computer looks for an operating system in that partition during boot. If the partition contains an incompatible OS or no OS at all, the error message is displayed. In this case, the technician has confirmed that the boot.ini file is correct, ruling out other potential causes such as GRUB Legacy, Windows Startup services, or an unsupported version of Windows.

The message "No boot device available" will be displayed. This message indicates that the computer is unable to find any device from which it can boot the operating system. Since the hard drive is not recognized, the computer cannot access the necessary files to start up. This could be due to a faulty hard drive or a problem with the connection between the hard drive and the motherboard.

Joe can set up alerts to let administrators know when backups fail in order to ensure that the backups will work if needed. This will allow the administrators to take immediate action and address any issues or errors with the backups, ensuring that they are functioning properly and can be relied upon for recovery if necessary. By being alerted to backup failures, the IT department can promptly troubleshoot and resolve any problems, minimizing the risk of data loss and maximizing the effectiveness of the backup plan.

Of all these options, WPA2 on a SOHO router is the most secure. Combined with Multifactor Authentication, it meets all the needs of the user.

And before you ask...RADIUS is for remote users and TACACS is an outdated alternative to Radius.

The technician is most likely performing image deployment on the computer. PXE booting is a method that allows a computer to boot from a network instead of a local hard drive. This is commonly used for deploying operating system images to multiple computers simultaneously. Therefore, the technician is likely using PXE booting to deploy an image onto the computer.

The correct answer is Display - Brightness. The user's mobile device is losing battery life rapidly and feeling warm to the touch, which indicates that the display brightness may be set too high. Higher display brightness consumes more battery power and generates more heat. By reducing the display brightness, the device will consume less power and generate less heat, thereby resolving the issue.

A MITM attack is done using spoofing to mask the attacker as someone trusted.

The correct answer is "Power Levels" because by adjusting the power levels of the wireless network, the small business can limit the range of the network signal. This will make it more difficult for the nearby company to connect and use the wireless connection without permission. By reducing the power levels, the network signal will be weaker and have a shorter range, making it more localized to the small business premises.

chkdsk is short for "Check Disk" and dism stands for "Deployment Image Servicing and Management"

• Dir would show a targeted directory and folders within
• Ipconfig would show the ip configuration for that device
• Format would format a disk
• diskpart would create a disk partition

Of these choices, chkdsk and dism are the only two that perform some measure of troubleshooting tasks related to the mentioned issue.

1. Identify malware symptoms. << Technician DID THIS


2. Quarantine infected systems. << THIS IS what the Technician should do next.


3. Disable System Restore.


4. Re-mediate: Update antivirus.


5. Re-mediate: Scan and remove.


6. Schedule scans and run updates.


7. Educate the end user.

The network administrator most likely gave the technician a physical network diagram. This diagram provides a visual representation of the physical layout of the network, including the switch-ports that need to be patched in for the network upgrade. It shows the physical connections between devices, such as switches, routers, and servers, and helps the technician understand how to physically connect the network components. The other options, such as process diagram, fiber backbone diagram, and logical topology diagram, do not specifically provide information about the switch-ports and their physical connections.

To determine the cause of the issue, the first step should be to check the application permissions. This is because the camera shutter noise may be triggered by an application that has been granted permission to access the camera even when the user is not actively using it. By checking the application permissions, the user can identify if any application has such access and disable it if necessary. This step will help narrow down the cause of the issue and potentially resolve it without the need for more drastic measures like uninstalling the camera application or resetting the phone to factory settings.

The network administrator must plan to document a backout plan to roll back changes to the router. This is important because even with thorough planning and risk analysis, there is always a possibility that the OS upgrade may cause unforeseen issues or disruptions to the network. Having a backout plan in place ensures that if any problems arise during or after the upgrade, the administrator can revert the changes and restore the previous functioning state of the router. This helps to minimize downtime and potential impact on the organization's network operations.
