CompTIA A+ 220-702 Essentials Practice Test....(Part 1)

Before attempting to use an extension magnet to pick up a screw inside a computer case, it is essential to unplug the power cord. This is necessary to prevent any possible shorts or electrical accidents that could occur while the technician is working inside the case. By disconnecting the power source, the technician ensures their safety and minimizes the risk of damaging the computer components or causing any electrical malfunctions.

After terminating an Ethernet cable, a technician would most likely use a cable tester. This device is used to check the continuity and proper functioning of the cable connections. It can identify any faults or issues with the cable, such as shorts or open circuits, ensuring that the cable is properly terminated and ready for use. A multimeter is used to measure voltage, resistance, and current, but it is not specifically designed for testing cables. Extension magnets are used to retrieve metallic objects from hard-to-reach places, and a toner probe is used for tracing and identifying cables in a network.

A stop error, also known as a blue screen, refers to a situation where the operating system encounters a critical error and cannot recover, resulting in a complete system failure. This error is displayed as a blue screen with error codes and can force the system to restart. On the other hand, a Dr. Watson error occurs before the Windows GUI (Graphical User Interface) appears and is often related to issues with the graphics adaptor or memory chip. It does not cause a complete system failure like a stop error.

The correct answer is "C:\Documents and Settings\". This is the default directory for User Profiles in Windows XP. It is where user-specific data and settings are stored for each individual user on the computer.

The most likely cause of the non-system disk error is that there is a disk in the floppy drive. This error typically occurs when the computer is trying to boot from a non-bootable disk, such as a floppy disk, instead of the hard drive where the operating system is installed. By removing the disk from the floppy drive, the technician can resolve the issue and allow the computer to boot from the correct drive.

An IEEE-1394 device, also known as FireWire or iLink, is a high-speed data transfer technology that allows for fast and efficient file transfers. Unlike USB ports, which have been disabled, IEEE-1394 ports may still be enabled on the work desktop computer, allowing the user to connect their home desktop computer and transfer the large work-related files.

The crumpled pages from the third tray indicate that there is an issue with the pickup rollers. Pickup rollers are responsible for feeding the paper from the tray into the printer. If they are worn out or damaged, they may not be able to grip the paper properly, causing it to crumple. Replacing the pickup rollers should resolve the problem and ensure smooth paper feeding.

The best option to use when attempting to check the DHCP status of a client machine is "IPCONFIG /all". This command displays detailed configuration information for all network interfaces on the machine, including the DHCP status. It provides information such as the IP address, subnet mask, default gateway, DNS servers, and DHCP lease information. This command is commonly used to troubleshoot network connectivity issues and verify DHCP settings.

When attempting to upgrade an older PC that currently only has USB 1.1 to USB 2.0, the applicable solution is to add a USB 2.0 expansion card. This will allow the PC to have USB 2.0 ports, which provide faster data transfer speeds compared to USB 1.1. Changing the legacy device settings in the BIOS or using an IEEE 1394 adapter are not relevant solutions in this case. A USB 1.1 to 2.0 adapter may not provide the desired upgrade in terms of speed and functionality.

The technician would use the "ping -t" command and switch to verify if the remote printer is back online. The "ping" command is used to send a network request to a specific IP address or domain name and receive a response back. The "-t" switch is used to continuously ping the target until it is manually stopped. By using this command, the technician can check if the remote printer is responding to network requests, indicating that it is online and operational.

The most likely problem in this scenario is that the port forwarding settings are not correct. Port forwarding is a technique used to allow external devices to connect to specific ports on a network. If the technician is able to connect to the internet but cannot connect to a remote machine through Remote Desktop, it suggests that the necessary ports for Remote Desktop are not properly forwarded. This could be due to incorrect configuration or settings in the router or firewall.

The correct path to disable a service in Windows XP is through Control Panel > Administrative Tools > Services. In the Services window, you can find a list of all the services running on your computer. From there, you can select the service you want to disable, right-click on it, and choose "Properties". In the Properties window, you can change the startup type to "Disabled" to prevent the service from starting automatically.

FIXMBR is the best command to resolve the missing NTLDR error. NTLDR (NT Loader) is a critical system file used by Windows operating systems to start the system. If it is missing or corrupted, the computer will not be able to boot properly. FIXMBR command is used to repair the Master Boot Record (MBR) of the system, which contains important information for the boot process. By fixing the MBR, it can restore the NTLDR file and resolve the error. FORMAT, DISKPART, and FDISK /MBR commands are not specifically designed to fix the NTLDR error.

The correct answer is Mail because port 25 is commonly used for SMTP (Simple Mail Transfer Protocol), which is responsible for sending and receiving email messages. By testing connectivity on port 25, the technician is specifically checking the functionality of the email application.

In this situation, where there are 50 computers transferring large amounts of data to various servers in a single room, the most suitable recommendation is to use switched full-duplex connections. Switched full-duplex connections provide dedicated bandwidth for each computer, allowing them to transmit and receive data simultaneously without any collisions or interruptions. This ensures efficient and high-speed data transfer between the computers and servers, making it the best option for this scenario.

A plastic shim would be the best tool to open the case of a laptop LCD screen because it is less likely to cause damage to the delicate components inside. Using a flathead screwdriver or metal shim could potentially scratch or puncture the screen or other internal parts. Pliers would not be suitable for this task as they are not designed for opening cases.

The most likely cause for the IDE hard drive not showing up in the operating system is that the primary controller BIOS setting is incorrect. The BIOS controls the basic functions of the computer and if the setting for the primary controller is not configured properly, it can prevent the operating system from recognizing the IDE hard drive. This can be resolved by accessing the BIOS settings and ensuring that the primary controller is set correctly.

The most likely cause of the problem is that the software requires the user to be an administrator. Since the technician installed and tested the program using an administrative account, it is possible that the program has certain features or functionality that can only be accessed or modified by an administrator. Therefore, when a regular user runs the program and makes configuration changes, the program fails to keep those changes because the user does not have the necessary administrative privileges.

When installing a wireless access point, the technician should first change the default password. This is important for security purposes as leaving the default password unchanged makes it easier for unauthorized individuals to gain access to the access point. By changing the default password, the technician ensures that only authorized individuals can access and configure the wireless access point.

The LCD cutoff switch is most likely causing the laptop to go into standby mode unexpectedly. The cutoff switch is responsible for detecting whether the laptop lid is closed or open. If the switch is faulty or stuck, it may send incorrect signals to the laptop, causing it to enter standby mode even when the lid is open.

Dual band routers allow for the simultaneous transmission of 802.11n at both 5.8GHz and 2.4GHz frequencies. This means that the router can support devices that are compatible with either of these frequencies, allowing for greater flexibility and improved performance. By transmitting on both frequencies simultaneously, the router can provide a more stable and reliable connection, as well as better coverage throughout the network. This makes dual band routers a popular choice for homes and offices that have multiple devices and require a strong and consistent Wi-Fi signal.

The most likely cause for the blank page after entering credentials on the newly created internal site is that a proxy exception has not been configured. When a user accesses a website through a proxy server, the proxy server may block certain sites by default. In this case, since the internal site is newly created, it is possible that the proxy server is blocking access to it. By configuring a proxy exception specifically for the new site, the user will be able to access it without any issues.

The correct answer is NET USE. The NET USE command is used to connect to and map a shared drive from a remote computer. This command allows users to access files and folders on a network share by assigning a drive letter to the shared resource. The TRACERT command is used to trace the route that packets take to reach a destination, the IPCONFIG command is used to display the IP configuration of a network interface, and the NSLOOKUP command is used to query DNS servers for information about domain names.

The default location for temp files in Windows 7 is C:\Windows\Temp.

The TYPE command is used to display the contents of a text file on the command line in Windows XP Professional. This command allows the technician to view the text file without opening any additional applications or programs.

A toner probe is a tool used to trace and identify network cables. It consists of two parts - a tone generator and a probe. The tone generator is connected to the network drop in the user's cubicle, and it sends a signal through the cable. The technician can then use the probe in the network room to trace the signal and find the correct drop. This allows the technician to identify the specific network drop that needs to be activated, making the port hot.

The fuser is responsible for melting the toner onto the paper, and if it is damaged, it may not be able to properly fuse the toner onto the paper in that particular area, resulting in a blank streak. The other options, such as rebooting the printer, having thick paper, or a low toner cartridge, would not typically cause a specific blank streak along one edge of each page.

Installing heat sinks on the RAM modules is the best practice in this situation because heat sinks help to dissipate the heat generated by the RAM modules, preventing them from overheating. This can improve the overall performance and stability of the system. Installing additional CPU fans may help with overall system cooling, but it may not specifically address the overheating issue of the RAM modules. Replacing the RAM slots is not necessary unless they are physically damaged. Installing a heat sink on the chipset driver is not relevant to the overheating issue of the RAM modules.

A cable tester would be used to troubleshoot this issue because it can help identify if there is a problem with the network cable connecting the laptop to the server. By using the cable tester, the technician can check for any breaks or faults in the cable that may be causing the connection issue. This tool can help pinpoint the specific problem and determine if the cable needs to be replaced or repaired.

When a user installs a PostScript driver for a printer that only supports PCL (Printer Control Language), the printer will not be able to understand the PostScript commands sent by the driver. As a result, the printer will print garbage or unreadable characters instead of the expected output. This is because the printer lacks the necessary capabilities to interpret and process the PostScript language.

Disabling the SSID from broadcasting prevents the wireless network from being visible to unauthorized users, making it more difficult for them to discover and connect to the network. Changing the default admin password adds an extra layer of security by preventing unauthorized access to the network settings and configuration.

The correct answer is that the sound card's optical plug is not connected. This explanation suggests that the red, laser-type light is emitted when the optical plug is not properly connected, indicating a connectivity issue rather than a defect or failure of the sound card.

A user can change the programs that run at startup in Windows XP by adding or removing programs from the startup folder. This folder contains shortcuts to programs that are automatically launched when the computer starts up. Additionally, the user can run msconfig (Microsoft System Configuration Utility) and configure startup programs. This utility allows the user to enable or disable programs that are set to run at startup, providing more control over the startup process.

The Manager is receiving this error because the Sales group, of which the Manager is a member, has the NTFS permission "Deny" for modifying the file. Even though the Managers group has the NTFS permission "Full Control Allow", the "Deny" permission takes precedence and overrides the "Allow" permission. Therefore, the Manager is denied access to update the file.

The correct answer is hard drive and memory. FRU stands for Field Replaceable Unit, which refers to components that can be easily replaced by the user or a technician without having to send the entire device for repair. Both the hard drive and memory modules in a laptop can be easily replaced by the user or a technician, making them FRUs. The sound card, modem, and video card, on the other hand, are not typically considered as FRUs as they require more technical expertise and may involve disassembling the laptop to replace them.

A user that belongs to both the Administrators and Users groups would have the access level of an Administrator. This is because the Administrators group typically has the highest level of privileges and permissions in a system, allowing them to perform administrative tasks and make changes to the system settings. Being a member of both groups would grant the user all the privileges and permissions associated with the Administrator group.

The size of the computer hard drive is the most important factor when using offline files on a networked computer because offline files are stored locally on the computer's hard drive. The larger the hard drive, the more offline files can be stored, allowing for greater accessibility and productivity when the computer is not connected to the network.

The most likely reason why the printer is displaying "Paper Jam C Front Door" is that something is stuck inside the pickup assembly. This could be causing the printer to have difficulty picking up the paper properly, resulting in paper jams. Replacing the fuser assembly, pickup rollers, or toner cartridge would not directly address this issue.

Task Manager is the best tool for changing the process priority of a background program. Task Manager allows the technician to view and manage all running processes on the computer, including background programs. It provides options to change the priority of a process, allowing the technician to allocate more system resources to the background program if needed. MSCONFIG is used for managing startup programs, Computer Management is used for managing system settings and resources, and Task Scheduler is used for scheduling tasks to run at specific times.

The technician is replacing a processor that is attached parallel to the motherboard. The Pin grid array processor is the correct type needed in this case. Pin grid array processors have an array of pins on the bottom that fit into corresponding holes on the motherboard, allowing for parallel attachment. Slot 2 and Slot 1 processors are not parallel attachment types, and a socket to slot adapter is not necessary in this scenario.

Using PING to attempt to reach the default gateway will verify that the network adapter is functioning properly and communicating on the LAN. The default gateway is the IP address of the router that connects the local network to other networks. By successfully pinging the default gateway, it confirms that the network adapter is able to send and receive data on the local network.

Executing %temp% from the run command will open the current user's temporary folder. The %temp% variable is a system variable that represents the path to the temporary folder for the currently logged-in user. Opening this folder allows users to access and manage temporary files that are created and used by various applications and processes on the operating system.

The best explanation for why none of the access points are listed is that they are out of range. This means that the desktop computer with the new 802.11n network adaptor is not within the range of any available access points.

If a laser printer displays 15% fuser remaining, it means that the fuser, which is responsible for bonding the toner to the paper, is nearing the end of its lifespan. However, it still has enough remaining to continue printing without any issues. Therefore, the printer will print according to specification, meaning it will continue to print normally until the fuser needs to be replaced.

Windows XP has a limitation where it can only recognize and utilize up to 137GB of storage on a hard drive without the installation of Service Pack 1. Therefore, the most likely problem in this scenario is that Service Pack 1 has not been installed on the machine, causing the limitation in recognizing the full 250GB capacity of the hard drive.

A cable tester should be used to troubleshoot the issue of a workstation no longer having network connectivity. This tool is specifically designed to test the integrity and connectivity of network cables. By using a cable tester, the technician can verify if the network cable is functioning properly or if there is a fault in the cable that is causing the connectivity issue. This will help identify if the problem lies with the cable itself, allowing the technician to take appropriate steps to resolve the issue.

The customer's system is infected with multiple viruses, including spyware and malware. In such a situation, it is important to prioritize the recovery of critical data. By removing the hard drive and copying the critical data to another system using an external dock, the technician can ensure that the data is safely transferred without the risk of further infecting the system. This method allows for a quick and efficient recovery of the important data within the given time frame.

A user should be added to the "Backup Operators" group for the ability to restore files without granting any ownership privileges. This group is specifically designed to allow users to perform backup and restore operations on a system without having full administrative control. By adding a user to this group, they will have the necessary permissions to restore files from backups, but they will not have the ability to make any other significant changes or modifications to the system. This helps to maintain security and prevent unauthorized access or modifications.

The technician should look for a proxy server that has been enabled in this situation. A proxy server acts as an intermediary between a user's computer and the internet, allowing it to control and monitor internet traffic. If a browser has been hijacked, it is possible that a proxy server has been enabled without the user's knowledge or consent. This can redirect internet traffic, collect sensitive information, or inject malicious content into web pages. Therefore, identifying and disabling any unauthorized proxy server is crucial to resolving the issue.

The correct answer is "attrib -s -h -r C:\BOOT.INI". This command will allow modification of the file C:\BOOT.INI by removing the "system" (-s), "hidden" (-h), and "read-only" (-r) attributes from the file.

To implement BitLocker on a Windows 7 Ultimate notebook hard drive, the technician should run the BitLocker wizard and any necessary partitions. This will allow the technician to set up BitLocker encryption on the hard drive. Additionally, the technician should enable TPM (Trusted Platform Module) in the system BIOS. TPM is a hardware component that provides additional security for encryption keys. By enabling TPM, the technician ensures that the encryption keys used by BitLocker are securely stored and protected.

The correct answer is "ping -t". The technician suspects a failing NIC, which could result in slow internet connection. By using the "ping -t" command, the technician can continuously send ICMP echo requests to a specified IP address and check for any dropped packets or high latency. If the NIC is failing, it may cause delays or packet loss, indicating a problem with the internet connection. The other options, such as "ipconfig /all" and "ping -a", provide information about network configurations and resolve IP addresses respectively, but they do not specifically test the performance of the NIC. "netsh winsock reset" is used to reset the Windows Socket API configuration and would not directly verify the failing NIC.

Installing a 1Gbps network adapter in the manager's laptop would increase the transfer speed because the current network adapter (802.11g NIC and 100Mbps Ethernet adapter) is limiting the transfer speed to 100Mbps. By upgrading to a 1Gbps network adapter, the laptop will be able to take full advantage of the 1Gbps network access speeds provided by the office, resulting in faster file transfers.

The technician should execute the "ipconfig /release" command next. This command will release the current IP address lease from the DHCP server, allowing the client to obtain a new IP address. This can help in resolving connectivity issues and establishing a proper connection to the Internet.

The technician should first check the application website for known hardware compatibility issues. This is because the user updated the application software and now the video display is not working with the new application. By checking the application website, the technician can determine if there are any known compatibility issues between the application and the hardware. This will help identify if the issue is due to compatibility and if any specific steps need to be taken to resolve it.

The application log is the best location for a technician to check for further information about the cause of the crash. The application log records events and errors specific to the applications running on the computer. By analyzing the entries in the application log, the technician can identify any errors or issues that may have caused the program to crash and the computer to lock up. This log provides valuable information for troubleshooting and resolving the crash.

The technician needs to have a USB header available before installing the new internal flash memory card reader into the floppy drive bay. This is because the flash memory card reader will require a USB connection in order to function properly. The USB header will provide the necessary connection for the device to communicate with the computer.

The correct answer is FORMAT because the FORMAT command is used to prepare a new disk for use by creating a file system on it. By running the FORMAT command on the new hard disk, the technician can make it accessible to users by formatting it with a compatible file system such as NTFS or FAT32.

A technician can use NBTSTAT utility to display NetBIOS over TCP/IP information. NBTSTAT is a command-line tool that shows the current NetBIOS over TCP/IP connections, including the local NetBIOS name table, the remote NetBIOS name table, and the NetBIOS session table. It provides information about NetBIOS names, IP addresses, and MAC addresses of connected devices, allowing technicians to troubleshoot and diagnose network connectivity issues related to NetBIOS.

The most likely problem is that the SATA port is faulty. This means that the port on the motherboard where the data cable connects to is not functioning properly, causing the new drive to not be recognized in the system BIOS. The other options are less likely to be the problem in this scenario. The jumper on the drive is not set would only be relevant if the drive was an older IDE drive, not a SATA drive. The drive not being formatted would not prevent it from being recognized in the BIOS. The BIOS not supporting SATA is also unlikely, as most modern motherboards have SATA support.

Moving the file to a new location on the same volume will retain its NTFS permissions. When a file is moved within the same volume, the file's metadata, including its NTFS permissions, is preserved. This is because the file system keeps track of the file's metadata and updates the file's location in the file system's master file table (MFT) without changing its permissions. On the other hand, copying the file to a new location on the same volume or moving the file to another NTFS volume will also retain the permissions. However, copying the file to another FAT32 volume will not retain the NTFS permissions as FAT32 does not support the same level of file permissions as NTFS.

When restoring a backup, it is important to enable the restore to include security settings. This ensures that the files being restored retain their original permissions and access rights. By enabling the restore to include security, the technician would have allowed the client to open the files without any issues.

Installing a PATA drive formatted with NTFS would improve the performance of the system. This is because PATA (Parallel ATA) drives have a higher data transfer rate compared to EIDE (Enhanced Integrated Drive Electronics) drives, which would allow for faster saving of large files. Additionally, formatting the drive with NTFS (New Technology File System) provides better performance and security features compared to FAT32 (File Allocation Table), further enhancing the system's performance.

The most likely cause of the problem is that the wireless client is using the wrong wireless adapter. This means that the adapter being used is not compatible with the IEEE 802.11a standard, which is the standard used by the wireless access point. As a result, the laptop is unable to connect to the network despite being configured correctly.

A TDR (Time Domain Reflectometer) is used to locate cable breaks in UTP (Unshielded Twisted Pair) cables. It works by sending a signal down the cable and measuring the time it takes for the signal to reflect back. By analyzing the time and intensity of the reflected signal, a technician can determine the distance to the break. This helps to pinpoint the exact location of the cable break, allowing for quicker and more accurate repairs.
