CompTIA A+ 220-702 Essentials Practice Test....(Part 2)

RAID 1 is fault tolerant and allows for disk mirroring. In RAID 1, data is mirrored on two or more drives simultaneously, providing redundancy. This means that if one drive fails, the data can still be accessed from the remaining drives. Disk mirroring ensures that the same data is written to multiple drives simultaneously, providing a backup in case of drive failure. Therefore, RAID 1 is a reliable option for fault tolerance and disk mirroring.

After removing the virus from the user's machine, the technician should check the web browser's proxy settings next. Proxy settings can sometimes be modified by malware, causing issues with internet access. By checking and potentially adjusting the proxy settings, the technician can ensure that the user can access the internet properly. Disabling port forwarding on the router, rebooting to Safe Mode, and formatting the machine and reinstalling the OS are not necessary steps in this scenario as the issue is likely related to the proxy settings.

If the CPU is not locked into the socket properly, it can cause the laptop to shutdown. The CPU needs to be securely fastened in the socket for proper functioning. If it is not locked in properly, it can cause an unstable connection and result in the laptop shutting down after a few seconds of being on.

The correct answer is continuous ping of an IP address until cancelled. The "-t" option in the PING command allows the user to continuously ping an IP address until they manually cancel the command. This is useful for monitoring network connectivity and latency over an extended period of time. The other options mentioned, such as reaching a count of 1000 or waiting for a response or return from the target, do not accurately describe the functionality of the "-t" option.

The reason the user cannot see the run command after upgrading to Windows Vista is because the run command is not displayed by default on the start menu.

The message "Missing NTLDR press any key to reboot" indicates that the computer is unable to find the NTLDR file, which is a critical component for the Windows XP operating system to start. This error is commonly caused by an incorrect boot order in the BIOS. By verifying the boot order in the BIOS, the technician can ensure that the computer is attempting to boot from the correct device, such as the CD drive, where the Windows XP Media Center installation files are located.

A multimeter is the correct device to determine the correct voltage being delivered to a desktop computer's power supply. A multimeter is a versatile tool that can measure various electrical properties, including voltage. By connecting the multimeter to the power supply, the technician can accurately measure the voltage and determine if it is within the required range or not. This allows them to identify any issues with the voltage and take necessary steps to rectify them.

The technician should check the POP3 protocol for incoming mail. POP3 (Post Office Protocol version 3) is a standard protocol used for receiving emails from a remote server to a local email client. It allows the user to download and access their emails from the server onto their device. By checking the POP3 protocol, the technician can troubleshoot any issues related to the user not receiving emails.

A wireless card on a laptop is typically inserted into a Mini PCI socket. This socket is specifically designed to accommodate Mini PCI cards, which are commonly used for wireless connectivity. PCIe and PCI are different types of expansion slots found on desktop computers, while AGP is an outdated graphics card slot. Therefore, Mini PCI is the correct answer for a laptop's wireless card socket.

The VER command is used to display the current version of the operating system running on a Windows computer. By running this command at a command prompt, the user can determine which Windows OS is installed on their computer.

To have the newly installed hard drive recognized by the system, the technician should initialize and format the hard drive through Disk Management. This process will prepare the hard drive for use by creating a partition and formatting it with a file system that Windows can recognize. Once the hard drive is initialized and formatted, it will be visible in Windows Explorer and ready for use.

The cause of the problem is that FAT32 cannot handle single files larger than 4GB. This means that when trying to transfer a 5GB file to the new drive, the file size exceeds the maximum limit supported by the FAT32 file system.

Enabling MAC filtering will prevent unauthorized devices from connecting to the network. By specifying the MAC addresses of the allowed devices, the router will only allow those devices to connect, thereby preventing new workstations from showing up under network neighborhood. This will also help in preventing the constant reboots of the SOHO router, as it will only allow authorized devices to connect and reduce the network traffic.

The correct next step would be to assign a static IP to the printer. Since the printer was never properly configured, it is likely that it does not have a valid IP address. By assigning a static IP, the printer will have a fixed address on the network, allowing users to connect to it and print. This step should be taken after verifying that the printer is plugged in and can print locally, as mentioned in the question.

The most likely cause of the computer responding slowly and spool.exe using 95% of system resources is the printing subsystem. The spool.exe process is responsible for managing print jobs in the Windows operating system. If there is a problem with the printing subsystem, such as a large number of print jobs or a printer driver issue, it can cause the spool.exe process to consume excessive system resources and slow down the computer.

The technician should have the customer run the loopback command first. Running the loopback command allows the technician to check if the network interface card (NIC) is functioning properly. If the loopback command is successful, it indicates that the issue is with the workstation's configuration or software. This helps narrow down the problem and eliminates the need to replace hardware components like the NIC or motherboard.

A loopback plug is the best tool to troubleshoot a DB-9 port because it allows for testing the port's functionality by creating a loop within the port itself. This means that any issues with the port, such as connectivity or signal problems, can be identified and resolved. Unlike the other options listed, a loopback plug specifically targets the DB-9 port and provides a simple and effective method for troubleshooting. An ohm meter measures resistance, an anti-static wrist strap prevents static discharge, and an oscilloscope is used for analyzing waveforms, but none of these tools are specifically designed for troubleshooting a DB-9 port.

Phone line voltages can damage Ethernet equipment. RJ-11 jacks are designed for phone lines, which typically carry lower voltages compared to Ethernet networks. Connecting a RJ-11 phone line jack to a RJ-45 Ethernet network port can result in higher voltages being applied to the Ethernet equipment, potentially causing damage. Therefore, it is important to ensure that a RJ-11 phone line jack is not connected to a RJ-45 Ethernet network port to prevent any potential damage to the equipment.

Enabling wireless encryption adds a layer of security to the wireless network by encrypting the data transmitted between devices. This prevents unauthorized access as the neighbor would need the encryption key to decrypt the data.

Disabling SSID broadcasting hides the network's name from being broadcasted publicly, making it more difficult for the neighbor to discover and connect to the network. They would need to manually enter the network name to connect, which adds an extra layer of security.

The technician should find voltage readings of +5V and +12V on the Molex connector. This is because the Molex connector is commonly used to provide power to hard drives, and the standard voltage outputs for the Molex connector are +5V and +12V. These voltage readings indicate that the power supply is providing the correct power levels to the hard drive, suggesting that the issue lies elsewhere in the troubleshooting process.

If the laptop is not displaying any video through the laptop screen or an external monitor, the most likely component that needs to be replaced is the video card. The video card is responsible for generating and sending video signals to the display. If the video card is faulty or not functioning properly, it can result in no video output on the screen. Replacing the video card should resolve the issue and restore video display on the laptop.

Based on the given information, the share permissions for \\SERVER\FILESHARE are set to "Read Only" for the Users group. Therefore, the login account USER1, being a part of the Users group, will have "Read Only" access to the files via the UNC path \\SERVER\FILESHARE. The directory permissions on the hard drive are not relevant in this case, as the share permissions take precedence.

The correct answer is that the new switches are configured for 10MB. This means that the switches are set to operate at a maximum speed of 10 megabits per second, which is significantly slower than what the office network requires. As a result, the speed of the Internet has drastically decreased since the network hardware refresh.

The cause of the Invalid boot disk error is that there is a CD-ROM in the drive. When a computer is trying to boot up, it checks various boot devices in a specific order, such as the hard drive, floppy drive, and CD-ROM. If there is a CD-ROM in the drive, the computer may try to boot from it instead of the hard drive, resulting in the error message. To fix this issue, the user should remove the CD-ROM from the drive and try booting up again.

CD-ROM, Hard drive, and DVD-ROM are the correct answers because these devices have the options of master, slave, and cable select. These options determine the device's role and behavior when connected to the computer's motherboard or controller. The master device typically controls the communication on the data cable, while the slave device follows the commands of the master. Cable select allows the devices to automatically determine their roles based on their position on the cable. This flexibility in configuration is commonly found in optical drives (CD-ROM and DVD-ROM) and hard drives.

Going back to a previous restore point would permanently solve the problem of malware reappearing on the computer. A restore point is a snapshot of the computer's system files, settings, and installed applications at a specific point in time. By restoring the computer to a previous restore point, any changes made by the malware, including its presence on the system, would be undone, effectively removing the malware and preventing it from reoccurring.

The technician should check the local print queue for a failed print job. This is because the user has already rebooted their computer twice and other users are not experiencing any problems, indicating that the issue is likely specific to the user's computer. Checking the local print queue will help identify if there is a failed print job stuck in the queue, which could be causing the printer to not print.

Before replacing the new motherboard, a technician should use a power supply tester. This tool is used to check if the power supply unit (PSU) is functioning properly. By testing the PSU, the technician can ensure that the motherboard will receive the correct amount of power and prevent any potential issues that may arise from a faulty power supply.

The correct answer is "statistics" because the question is asking about the variable used to find out the number of files sent by the workstation service when using the NET command. The "statistics" variable would provide this information.

The easiest solution to implement for the issue of random lighter printing areas in an office laser printer is to replace the toner cartridge. This is because the toner cartridge is responsible for supplying the toner, which is used to create the image on the drum and transfer it onto the paper. If the toner cartridge is old or faulty, it may not be distributing the toner evenly, resulting in lighter areas on the printed pages. By replacing the toner cartridge, the printer will have a fresh supply of toner and should be able to print evenly again.

Booting from the floppy disk or CD-ROM prior to scanning is a method used in the removal of a boot sector virus. This is because booting from a clean and trusted source, such as a floppy disk or CD-ROM, allows the computer to bypass the infected boot sector on the hard drive. By doing so, the virus is not loaded into memory, which enables the antivirus software to effectively scan and remove the virus from the system.

A yellow exclamation mark next to a device in Device Manager indicates that the device driver is missing. This means that the operating system is unable to locate the necessary software to communicate with the device. Without the driver, the device will not function properly, if at all.

The most likely cause for the Page cannot be displayed error is that the device cannot locate a DHCP server. This is indicated by the IP address assigned to the computer (169.254.10.70), which falls within the Automatic Private IP Addressing (APIPA) range. When a device is unable to obtain an IP address from a DHCP server, it automatically assigns itself an IP address within this range. This suggests that there is no DHCP server available to provide the device with a valid IP address, resulting in the inability to access the website.

A SATA drive requires an adapter when connecting to a Molex connector. Molex connectors are typically used for older power supply units, while SATA drives use a different type of power connector. Therefore, an adapter is needed to convert the Molex connector to the appropriate power connector for the SATA drive.

When an NTFS-formatted USB drive is inserted into a USB port on a second computer, the accessibility of the files and folders on the drive will depend on the set permissions. This means that if the second computer has different permission settings compared to the original computer, the files and folders may or may not be accessible. The permissions determine whether the user has the necessary rights to access the files and folders on the drive. Therefore, the answer "Files and folders may or may not be accessible depending on set permissions" is correct.

Upgrading the video card can increase performance in this case because the user states that the computer performance is slow when the Aero settings are enabled. Aero is a graphical user interface feature in Windows Vista that requires a certain level of graphics processing power. By upgrading the video card to a more powerful one, the computer will be able to handle the Aero settings more efficiently, resulting in improved overall performance.

The technician would use the "chkdsk c: /r" command to locate bad sectors and recover readable information. The "/r" parameter stands for "repair" and instructs the chkdsk command to locate bad sectors on the hard drive and attempt to recover any readable information from them. This command is commonly used to fix disk errors and recover data on a malfunctioning workstation.

To confirm the authenticity of a new virus definition file, a technician can check the hash key. A hash key is a unique alphanumeric value generated by a cryptographic algorithm. By comparing the hash key of the downloaded file with the official hash key provided by the antivirus software vendor, the technician can verify if the file has not been tampered with or modified in any way, ensuring its authenticity. This method ensures that the file has not been compromised or infected with malware during the download process.

Putting a firewall or router with NAT (Network Address Translation) between the computer and the Internet is the best method of connecting a home computer to the Internet in order to protect and secure the computer from malicious Internet attacks and scans. NAT acts as a barrier between the Internet and the computer, hiding the computer's IP address and providing an extra layer of security. It helps to prevent unauthorized access and filters incoming and outgoing traffic, reducing the risk of malicious attacks. This method provides a secure and controlled connection for the home computer.

The firewall being turned on is the likely cause of the issue. Windows XP computers may not be able to connect to the new computer because the firewall on the new computer is blocking incoming connections. To resolve this, the firewall settings on the new computer should be adjusted to allow incoming connections from the Windows XP computers.

The printer being out of paper could be a possible problem because if there is no paper, the printer will not be able to print the documents. Additionally, if the spooler is not functioning, it can cause issues with the printing process as the spooler is responsible for managing print jobs.

The error message "No Input Detected" suggests that the monitor is not receiving any signal from the video source. Since a video card has been added to the system, it is likely that the monitor is still connected to the on-board video controller instead of the newly installed add-on video card.

The technician should recommend installing an IEEE1394b video capture card. This is because the computer is already state-of-the-art in terms of hardware, so the issue lies with the external legacy USB 1.1 video capture card. By installing an IEEE1394b video capture card, which is a faster and more modern connection, the computer will be able to capture video from the HD camera at a higher speed and improve its video capture capabilities.

The correct answer is User Account Control; it can be turned off under User Accounts in the Control Panel. User Account Control (UAC) is a feature in Windows Vista that prompts users for confirmation before running most applications or making system changes. To turn off this functionality, users should navigate to the User Accounts section in the Control Panel and disable UAC.

Performance Monitor is the correct answer because it is a tool in Windows that provides detailed statistics and performance data about various system resources, including disk I/O. It allows users to monitor and analyze the performance of their computer's hardware and software components, and provides detailed information such as disk read/write speeds, disk queue length, and other relevant metrics. Task Manager, Computer Management, and Device Manager may provide some information about disk I/O, but Performance Monitor is specifically designed to gather the most detailed statistics in this regard.

To access the administrative share on the company's file server called "documents$", two requirements must be met. First, the user must know the exact network path to the folder, which means they need to know the specific location of the administrative share on the network. Second, the user must have proper access rights assigned to the folder, indicating that they have the necessary permissions to access and interact with the administrative share. These two factors are crucial for accessing the administrative share from a computer on the company's intranet.

192.168.0.1 is commonly used for internal IP addressing because it belongs to the private IP address range specified by the Internet Assigned Numbers Authority (IANA) for use in private networks. This address range is reserved for use within local area networks (LANs) and is not routable on the internet. 192.168.0.1 is often used as the default gateway IP address for home routers and is commonly used for configuring network devices within a private network.

A power supply tester would be the most suitable tool to troubleshoot the reported issue. Strange noises and random power offs are often caused by a faulty power supply. By using a power supply tester, the technician can check if the power supply is providing the correct voltage and if it is functioning properly. This will help identify if the power supply is the root cause of the problem and determine if it needs to be replaced.

The best explanation for a system experiencing intermittent memory errors is that the memory sticks have corroded contacts. Corroded contacts can cause poor electrical connections between the memory sticks and the motherboard, leading to intermittent errors. This can result in data corruption, system crashes, and other memory-related issues.

When a disk is listed as foreign in the Device Manager, it means that the disk was previously used in another system with a different configuration. To make the disk usable, it needs to be imported. Importing the disk will allow the current system to recognize and access the disk's data. This is necessary before any further actions, such as converting the disk to basic or dynamic, can be performed. Running Windows Update is not relevant in this scenario.

NSLOOKUP is a command-line tool used to query the Domain Name System (DNS) to obtain information about a specific domain or IP address. It is primarily used to translate an IP address to a corresponding hostname or domain name. By entering an IP address into NSLOOKUP, it will retrieve the associated domain name, providing a reverse DNS lookup. This can be useful for troubleshooting network connectivity issues or verifying the ownership of a particular IP address. Therefore, the correct answer is "translate an IP address to a name."

The correct answer is bootmgr.exe, winload.exe, winresume.exe. In the Windows Vista startup process, NTLDR has been replaced by bootmgr.exe, which is responsible for locating the operating system and loading it into memory. Winload.exe is then used to load the Windows operating system kernel (ntoskrnl.exe) and essential system files. Finally, winresume.exe is responsible for resuming the system from hibernation or sleep mode.

A faulty CMOS battery is the most likely problem in this scenario. The CMOS battery is responsible for providing power to the CMOS chip, which stores the BIOS settings. If the battery is faulty, it may not be able to provide sufficient power to the CMOS chip, causing the BIOS to reset and take the user into the BIOS setup instead of booting up normally. This can be resolved by replacing the faulty CMOS battery.

Disabling SSID broadcast and changing the SSID from default are two items that can be configured on a wireless router to make it more difficult for attackers to gain access. Disabling SSID broadcast prevents the router from broadcasting its network name, making it less visible to potential attackers. Changing the SSID from default adds an extra layer of security as attackers often target routers with default settings. By changing the SSID, the attacker would need to spend more time figuring out the network name, making it harder for them to gain access.

The technician should install the latest WAP firmware. This is because the WAP (Wireless Access Point) is not listing WPA2 as an option, indicating that it may not be compatible with the current firmware. By installing the latest firmware, the technician can ensure that the WAP supports WPA2 and can properly configure it for the SOHO setup.

The correct answer is COPY /Y because the /Y switch in the COPY command allows the technician to copy a file without prompts. When the /Y switch is used, any existing file with the same name as the file being copied will be automatically overwritten without any prompts or confirmation messages. This saves time and allows for a quicker and more efficient file copy process.

The possible causes for the program continuously prompting to insert blank media are:
1) A CD is inserted into the drive, which is not compatible for copying a DVD.
2) A DVD is inserted upside down in the drive, preventing the program from recognizing it as blank media.
3) The wrong DVD type is inserted into the drive, meaning it is not compatible for copying.

Installing a USB 2.0 firmware update on the motherboard is the most likely solution to provide USB 2.0 functionality in this scenario. This update will ensure that the motherboard's firmware is compatible with USB 2.0 devices and will enable them to run at the correct speed. This solution is preferred over the other options because it directly addresses the issue with the system's USB functionality and does not require any additional hardware or cables.

Port 22 should be forwarded on the firewall to make SSH management accessible from the Internet. SSH (Secure Shell) is a protocol that allows secure remote access to a computer or server. By forwarding port 22, incoming SSH connections can reach the server through the firewall, enabling remote management and administration.

The correct answer is "arp -a" because the "arp -a" command is used to display the ARP (Address Resolution Protocol) cache table, which contains the IP address to MAC address mappings. In this case, the line "00:0C:24:09:08:07 10.0.0.1" represents an entry in the ARP cache table, where the MAC address "00:0C:24:09:08:07" is associated with the IP address "10.0.0.1".

A DHCP server is responsible for assigning IP addresses, as well as other network configuration parameters, to DHCP clients. Among the options provided, a DHCP server can provide the IP addresses of WINS server, DNS server, and the default gateway to the DHCP client. The WINS server is used for NetBIOS name resolution, the DNS server is used for domain name resolution, and the default gateway is the router that connects the local network to other networks.
